If you are looking to purchase a pair of speakers in order to install in your house, you will often be confronted with a series of odd terms describing its performance. But how do these numbers relate to how the loudspeaker sounds and how are these to be interpreted? Now I will clarify the “power” rating of speakers. This specification is one of the most fundamental and possibly important specs to understand.

“Wattage” is occasionally also known as “Power” or “loudspeaker output power”. To put it in a nutshell, “wattage” relates to how much power your loudspeaker can endure without damage. The bigger this number typically the louder your loudspeakers. Depending on your application, you can choose a small loudspeaker tolerating merely a few watts or a larger one enduring several hundred watts. Many smaller home speakers merely can be driven with a few watts power which usually is adequate for a small space. If you intend to shake your walls then you clearly wish to choose a loudspeaker that has up to a few hundred watts. Most loudspeakers will have increasing music distortion as output power increases. For that reason, you want to get a loudspeaker that offers bigger output power than you are going to in fact require. This is going to assure that you are going to never drive the speaker into regions of high distortion.

Wattage is either specified as “Watts peak” which means the speaker can tolerate quick burst of this amount of power or “Watts rms” which shows how much output power the loudspeaker may tolerate for a longer period of time. The peak power rating in history often led to producers displaying big wattage ratings for tiny speakers. On the other hand, in reality these loudspeakers would not be able to endure larger levels of output power for longer amounts of time.

Nowadays most loudspeakers is going to state rms power that provides a better hint of the speakers’ true performance. Then again, please ensure that your speaker offers adequate headroom in order to avoid clipping of the audio. Having an adequate amount of headroom is crucial because music signals vary a great deal from sine wave signals that are utilized to determine rms wattage. Brief peaks of high wattage are often found in music signals. These peaks will drive the speaker into high distortion unless the peak wattage is large enough.

Please note that often the peak wattage that your amplifier can deliver to your speakers depends on the impedance of your speakers which is usually between 4 and 8 Ohms. An audio amplifier which has a set internal supply voltage will have a maximum output voltage swing which is restricted by that supply voltage. If you are driving an 8-Ohm speaker then your amp must deliver two times the output voltage than when driving a 4-Ohm speaker to deliver the same amount of output power to your speaker. Thus often maximum output wattage is specified for a specific loudspeaker impedance.

I just recently purchased and installed one of those poor boyz. The high quality is leading notch, but it is a little too much power for my Infinity Refference speakers. This alpine cda 9856 is best for someone who’s preparing on or already has a subwoofer. It’s a effective deck!

I’d suggest alpine even when you didnt want ipod connectivity simply because it’s such a good brand. I’ve used JVC, Sony, Pioneer in the past and alpine sounds much better than all of them.

The ipod interface is unmatched by any other vehicle audio business, period. it is the only company that provides complete speed ipod manage (no lag via an external ipod adapter, which can cost as much as $100) and an extreemly simple to use interface.

The ipod controls are almost precisely what you see on your ipod screen (which is replaced by an “///ALPINE” Logo when plugged in and tucked away in a glove box) except there’s only one line of text. You are able to do artist searches, playlist searches, song searches all withot lag. And yes, there’s a way to just shuffle all the songs on the ipod. The ID3 tag information is displayed on the display as well.

The only factor i could recomend besides this head unit, is the CDA 9857 because it has a 2 line display (a dot-matrix style display) but i couldnt justify spending an extra $150 just for that (that is, indeed, the only distinction). The single line display does just fine.

These products fall into 2 categories. The first category of products already has wireless built in. Second-category products, such as some streaming audio devices, have optional wireless capability. Typically they have a slot to insert a wireless LAN card. Latest generation iPods and cell phones already come with built-in WiFi and Bluetooth support.

Bluetooth is fairly widespread as a low-cost wireless solution. Still, Bluetooth does have some pitfalls. These weaknesses are frequently overlooked but will have an effect on high-quality audio applications.

1) Restricted operating range

The range of Bluetooth devices is generally only 30 ft. This excludes Bluetooth from multi-room applications.

2) Inadequate data transmission capacity

Bluetooth offers a maximum reliable data rate of around 1 Mbps only. This rate is not high enough to send uncompressed CD-quality audio. Therefore Bluetooth wireless devices apply audio compression. Audio compression will degrade the audio quality to some extent. High-quality audio transmission generally does not tolerate this type of degradation. As a result Bluetooth is usually not used in high-end audio devices.

3) Audio delay

The signal sent via Bluetooth will bear a slight delay of a minimum of 10 ms. This is for the most part due to the audio compression. While being uncritical for MP3 players, this delay may be a dilemma for video and other real-time applications.

4) No support of multiple headphones

Bluetooth does not support any quantity of headphones which may be a dilemma if you have a larger number of people who want to listen to headphones from a single transmitter device.

Another widespread protocol is WiFi which supports uncompressed audio but also has limitations simultaneously streaming to many receivers. Because of the high availability, WiFi is practical for streaming audio from a PC. On the other hand, WiFi products have relatively high power consumption. Because of this wireless headphones typically do not use this technology.

While newest-generation wireless speakers and wireless amplifiers use proprietary digital technologies, low-cost devices frequently still rely on FM transmission which is noisy and has high audio degradation and high susceptibility to radio interference.

Modern wireless audio protocols avoid audio degradation by employing digital transmission. These frequently also come with mechanisms such as forward error correction to cope with interference from other wireless devices.

Sophisticated wireless amplifier devices support uncompressed digital audio streaming to maintain the original audio quality. A few of these protocols allow streaming to an infinite number of wireless amplifiers which is convenient for whole-house audio distribution.

Some of these protocols support low-latency audio transmission which assures that the audio of all speakers will be in sync in a multi-channel application. These wireless audio transmitters normally work at 2.4 GHz. There are also some devices including Amphony’s line of wireless audio devices that work at 5.8 GHz. Products that operate at 5.8 GHz have less competition from other wireless products than those utilizing the crowded 2.4 GHz frequency band.

These wireless amplifiers also differ regarding amplifier output power, standby power consumption and audio quality. A high-quality audio amplifier is fundamental for optimum sound quality. Wireless Class-D amplifiers usually have standby power of 5 Watts or less and a power efficiency of larger than 80% but sometimes high audio distortion. Selecting a low-distortion amplifier is essential. Good-quality wireless amplifiers have audio distortion of less than 0.05%.

You should also consider safety when installing speakers. Damage, injuries, and added costs can be caused if speakers are not installed properly. As for the protection of hearing/vision, it should be used as necessary.

For installing speakers, here are some fundamental steps to follow. For some vehicles, it’s possible that they would require extra steps. Methods should be comparable even though the speaker’s location in your vehicle may vary from mounting locations.

Ascertain if the vehicle has speaker grilles that are removable if you are to install on the dash or door. If the grilles are removable, then here’s what you have to do: utilize appropriate tools to remove the grilles, remove the screw that are holding the speakers in, disconnect and connect the speaker harness to the new speaker, plug speaker harness, set speaker in the opening, reinstall using the screws for mounting, then replace the grille. You need to make sure that window operation won’t be interfered and affected by the speaker’s depth once you’ve installed in the door.

The dash pads or door panel will have to be removed if the grilles are not removable. Just pay close attention to any screws or clips that are removed. Aside from following the same steps above, you will also need to reinstall the door panel or dash pads. The screws that can be mounted in the armrest, behind the trim panels or inside the door latch space are what you need to be aware of when you’re removing the door panel. Raise the panel up after all the screws are removed so you can disconnect any wiring harnesses.

If you’re planning to install rear deck speakers, you first need to determine whether these speakers are top-mounted or bottom-mounted. Remove grilles and screws, disconnect and connect the speaker harness to the new speaker, plug in the harness, mount the speaker and replace the grille if these are top-mounted screws. For bottom-mounted speakers, reach in the trunk then remove the screws that are mounting the speaker. Then you can continue on following the basic steps above.

To check the operation of the new speakers, turn on the radio.

How many times have you ever thought about Audio Electronics? It may surprise you but it is actually something many people need at some point. However you should understand that most people actually have little idea what Car & Vehicle Electronics truly is! It is my greatest hope that through my articles I am able to pass on my deep knowledge of the subject to you, and that you will enjoy it every bit as much as I do.

It is tempting to consider the freedom which cordless loudspeakers promise and the comfort of adding audio anywhere in your home. Wireless speakers require power to drive the speaker elements and normally come with a power cord which needs to be plugged into an outlet. To eradicate the power cable, a number of cordless speakers have rechargeable batteries to power the inside amplifier that enables them to be placed virtually everywhere. Loudspeakers with moderate audio power, however, require quite heavy batteries which makes logging the loudspeakers to a place where the batteries may be recharged fairly of a hassle. Further batteries am going to age over time and need to be replaced.

Be confident to pick a speaker which offers enough audio power for yor application. If you are planning to set up your speakers in your kitchen or bedroom, you can select a reasonably low-powered loudspeaker. Then again, if you are preparing to set up cordless loudspeakers outdoors or in your home theater, you might want to take a look at average to high output power speakers. Depending on whether you are planning to use the speaker inside or outdoors, you might want to go with a loudspeaker which is rainproof or at the least water resistant.

After that, make sure the transmitter provides the right audio inputs for your audio equipment. First check what sort of audio outputs are accessible. Next confirm that your transmitter may connect properly. Clearly if the transmitter offers more than just one type of input, you will have more flexibility in case your audio equipment changes down the road. If you wish to connect your transmitter to your surround system, you might require loudspeaker terminal inputs unless your surround equipment provides line level audio for your rear speakers. If you have an iPod or iPhone you may wish to pick a transmitter with a built-in iPod cradle. Many transmitters will at least have a line-level audio input. Every audio device will output audio at different audio levels. To accomodate all devices, the transmitter must be able to adjust its audio input level. This will steer clear of clipping of the audio and take full advantage of the audio fidelity of the cordless transmission.

Several of the most recent cordless product models employ digital audio transmission generally either at 2.4 GHz or 5.8 GHz. These kinds of speakers eliminate the audio distortion and noise that are inherent to speakers that employ analog audio transmission, generally at 900 MHz. Another benefit of digital transmission is the higher robustness against interference from other transmitters such as cordless telephones which is essential with the ever increasing number of wireless gizmos these days.

While purchasing loudspeakers, a listening test is always a good idea. Nevertheless, keep in mind that the sound quality will also depend on your environment. However, if you cannot find a pair of cordless speakers which sound just right, or if you already have a couple of loudspeakers, why not make your existing speakers cordless by using a wireless speaker kit? These kits have a transmitter and one or more wireless amplifiers which can connect directly to your existing loudspeakers.

There are lots of separate types and styles of headphones on the market starting with in-ear headphones as being the smallest headphones, some of which have a bracket that is worn around the ear. These type headphones can simply be stored in a pocket. They are frequently bundled with iPods or MP3 players. Another type of headphones which are larger than in-ear headphones sit on the ear and include an flexible frame which either sits on the skull or wraps around the neck. If your budget is tight then you should possibly focus on these types of headphones. They are the least expensive of all types. Some types offer insulation from outside noise to some degree.

If you are able to spend more, you could take a look at medium-end headphones which are bigger than these very tiny type headphones. Each earpiece has an ear cushion that depending on the model either sits on top of your ears or wraps around your ears. The second design eliminates the pressure on the ears and is preferred by many people. The next decision you’ll have to make is between an open and closed headphone design. An open design in essence means that the sound from the transducer will penetrate to the outside of the headphones. It can also cross-couple into the other earpiece. While a number of people believe that an open design sounds light, a closed design will tend to absorb outside noise more and offer improved insulation between the two earpieces.

Today’s headphones are dynamic headphones for the most part. Dynamic indicates what kind of transducer is used. Static headphones are the second type. This type is fairly expensive but offers high sound quality. Static headphones need a special headphone amplifier.

Wireless headphones are an additional alternative which avoid the headphone cable. One choice to think about are Bluetooth headphones. Bluetooth headphones are a category of cordless headphones which are designed for Bluetooth-enabled products. Such devices include cell phones. The range of Bluetooth headphones is usually less than 30 ft and the sound quality does not rival the quality of corded headphones.

Other cordless headphones include low-cost 900 MHz types which utilize FM transmission and more advanced digital wireless headphones which operate at 2.4 GHz or 5.8 GHz. FM wireless headphones have noticeable static and audio distortion. They are also prone to interference from other wireless devices.

Digital wireless headphone models encode audio data prior to the transmission. This makes this type of headphones superior in terms of sound quality. Digital wireless headphones are also relatively robust against interference. A number of digital wireless headphones work at the less crowded 5.8 GHz frequency band. This band provides less competition from other wireless devices compared to the 2.4 GHz band.

Running audio in your house can be a intimidating undertaking. Many buildings are not wired for multi-room audio and getting the music from your living room to your bedroom can be quite a problem. Products which solve this difficulty are commonly based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.

Infrared wireless audio products are restricted to line-of-sight applications, i.e. only function within a single room since the signal is broadcast as infrared light which can’t penetrate walls. This technology is often found in wireless speaker kit products.

RF wireless products broadcast the music as RF waves – either by using FM transmission or digital transmission – and can as a result easily transmit through walls. The least expensive option is FM transmission. Products using FM transmission, however, have a series of drawbacks. These include degradation of the audio quality due to noise or hiss and audio distortion. In addition, FM transmitter products are also rather prone to interference from other wireless transmitters.

Products which utilize digital wireless audio transmission utilize a digital protocol. Such products include transmitters from Amphony. In this protocol, before transmission the audio signal is converted to digital data. Some wireless audio transmitters will use audio compression, such as Bluetooth transmitters which will lower the audio quality to some extent. Digital wireless audio transmitters which send the audio uncompressed offer the highest audio fidelity.

Products using wireless LAN are useful when streaming audio from a PC. Their disadvantage is that they normally have some fairly high latency, i.e. the signal will be delayed by some amount since wireless LAN was not particularly designed for real-time audio streaming. WLAN receivers often do not have built-in network access. As a result, such products frequently require purchasing separate LAN cards. These cards are then plugged into each receiver.

Powerline products send the audio via the power mains and offer large range. They run into trouble in homes where there are separate mains circuits in terms of being able to cross over into another circuit. Powerline products have another problem in the form of power surges and spikes which can cause transmission errors. To prevent audio dropouts, these products will usually have an audio latency of several seconds as a safeguard.

Here are some suggestions for choosing a wireless audio system: If you plan to stream audio into several rooms of your home, be certain to pick a system that allows streaming to multiple receivers at the same time. That way you don’t have to buy a separate transmitter for each receiver that you are streaming to. Some devices have some sort of error correction built in which will help guard against dropouts in case of strong wireless interference. Pick a digital RF audio transmitter to ensure that the audio quality is preserved. Make sure the audio latency is smaller than 10 ms if you have a real-time application such as video.

Select a transmitter that has all the audio inputs you require, such as speaker inputs, line-level RCA inputs etc. Choose a system where you can add receivers later on which provide all of the necessary outputs, e.g. amplified speaker outputs, RCA outputs etc. Given that you may want to connect the transmitter to several sources, you should select a transmitter that can be adjusted to different signal volume levels to prevent clipping of the audio signal inside the transmitter converter stage.

For high amplifier power efficiency and greatest sound quality, confirm that the amplified receiver has a built-in low-distortion digital amplifier. Pick a system that offers receivers that can drive speakers with the desired Ohm rating. Make sure the receivers have a small form factor and are easily mountable. This will help during the installation. Products using the less crowded 5.8 GHz frequency band will commonly have less trouble with wireless interference than 900 MHz or 2.4 GHz devices.
