Installing an Aquasonic Underwater Speaker is easy both during your pool construction and after.

If you already have an existing pool, the underwater speaker can also be used by dropping it in the pool by the waterproof cord. The unit simply rests along the edge of the pool floor.

Underwater Speakers - How They Work
Designed for applications ranging from synchronized swimming and diver communication to recreational/therapeutic pools, ClarkSynthesis Aquasonic underwater speaker provides superior full-range fidelity. Why? Waterborne vibrations have less effect on the ear drum than do airborne vibrations. As a result, there tends to be a muted quality to underwater sound. This is why ordinary underwater loudspeakers don't win many awards for fidelity. However, if waterborne vibrations are strong enough, they also are conducted through the bones near our ears. This process - known as bone conduction - sends tactile sound vibrations directly to the inner ear, where they are translated into electrical signals for the brain (i.e., sound). This technology is what gives these transducers that feel-it-in-your-bones rich sound. Clark Synthesis' patented Aquasonic underwater loudspeakers are powerful compression drivers similar to the acclaimed Tactile Sound Transducers (TSTs) used in home theaters and other sound systems.

An Aquasonic underwater speaker produces strong vibrations over a full range of tactile and audible frequencies, providing high-quality underwater sound through a combination of acoustic transmission and bone conduction. Aquasonic speakers contain two elements: the main driver (for bass and middle frequencies) and an attached acoustic lens for improved high-frequency fidelity. Standard Aquasonic models are designed to either hang into the water by a cord or be installed in-wall in a standard pool light fixture. WTL models are designed specifically for installation inside Amerlite (Pentair) brand pool light fixtures. All Aquasonic underwater speaker models include 100-feet of built-in, Enduroflex waterproof speaker cable.

About Clark Synthesis
Clark Synthesis's transducers were originally developed for flight simulation. The patented design actually allows you to FEEL the music and was discovered to lend itself very nicely to underwater applications. It's one of the reasons they were issued U.S. Patent #5,473,700. The real 'secret' behind the Clark design is in their uniquely versatile shape and construction. And indeed they do perform, in the qualified opinion of many long-time audiophiles, better than anything else that we've experienced both in and out of the water. The unique design offers in-wall and drop-in capabilities.

Underwater Speakers Applications

This underwater speakers has been use for aquatic therapy, swim-in-place exercise pools, major luxury resorts, the Olympic Training Center in Colorado Springs, the Watsu Pool at the Mauna Lani Resort in Hawaii, for Dolphin Dance at Kelani Institute, Cirque du Soleil "O" at the Bellagio, synchro swim teams, marine biology studies, diver communications for the Navy, and at Seaworld to train orcas.

Do you need any kind of mounting kit or do these just mount right into the large pentair niche?

A     Answered on 6/29/2016 by Lennox H.

Hi Kyle, The In-Wall installation does require the Pentair large niche. The In-Wall Assembly Kit p/n AQ339KIT comes with everything needed for installation in a concrete pool and AQ339KITFV for Vinyl or Fiberglass pool.

I am building a lap pool. Dimensions are 12 x 67 feet long. How many speakers will be required? Thanks

A     Answered on 2/25/2016 by Patrick P.

How Many Speakers – The rule of thumb is one speaker for every 20’ x 20’ (or 400 square foot) section of pool. So for a 20’ x 40’ pool, you would use two underwater speakers. Some speakers have minimum and maximum depth ratings so be sure to consider this before installation.

Can this speaker be used in a pool with a salt chlorine generator?

A     Answered on 8/13/2012 by Patrick P.

According to the manufacturer, the AQ339 Aquasonic underwater speaker is designed to work in a salt water pool. They said that due to the low level of salt used (3000 PPM) there is no problem using this speaker.

Can the Aquasonic speakers be used out of the water?

A     Answered on 8/13/2012 by Patrick P.

According to the manufacturer, the AQ339 Aquasonic speakers do not transmit sound through the air, only underwater.

I'm an oceanographer looking for an underwater speaker that I can hang over the side of a ship and transmit acoustic signals. What is the maximum working depth (or pressure) for your AQ339 Aquatic Pool Speaker?

A     Answered on 8/13/2012 by Patrick P.

The manufacturer does not recommend using the AQ339 speaker in ocean water as it isn't designed for salt water use and is only sound tested to a depth of 10 feet.  We do carry Lubell underwater speakers and their LL916C 180dB Professional Underwater Speaker can be used in ocean water.

I live overseas and am interested in purchasing this speaker but our electrical is 240V 50 Hz, will this speaker work overseas?

A     Answered on 5/26/2009 by Patrick P.

The speaker is simply a speaker. AC Power requirements only apply to the amplifier. We recommend that you use an amplifier that delivers 125 to 150 watts into 4 Ohms.

How many feet of under water cable is included?

A     Answered on 4/30/2009 by Patrick P.

The AQ339 includes 100' of under water cable.

Can you hook an I-Pod up to this speaker?

A     Answered on 4/14/2009 by Patrick P.

We spoke with the manufacture of the AquaSonic speaker and they stated that you would plug your I-Pod into an amplifier and then the amplifier is wired to the speaker. The needed amplifier for the AquaSonic speaker is a 125 - 150 Watt into 4 Ohm.

?     Asked on 8/6/2008 by Guest

What is the maximum depth for this speaker?

A     Answered on 8/6/2008 by Patrick P.

The manufacture tests the pool speakers down to 10 feet.  However, recommend that they only be used down a few feet, which is the standard depth for a light niche. The manufacture will not warranty anything below 10 feet.

?     Asked on 8/4/2008 by Guest

What is the rated power of the speaker in watts in air? Any boat mount accessories? Could this be used to heard fish?

A     Answered on 8/4/2008 by Patrick P.

The Aquasonic is rated at 135 watts at 4 ohms.  The speaker does not produce much sound in air and should not be used as an air speaker. We do not provide any boat mount accessories. While the Aquasonic can reproduce sounds in the range of hearing for many fish (30 Hz to 4 kHz), and the Aquasonic is used in some underwater animal training programs, we are not aware of anyone using the Aquasonic to affect the behavior of fish.

My pool contractor is starting to dig tomorrow and I'd like to get him to install a couple of these speakers in my 20'x40' free form pool. How many speakers should I have ideally? The pool will have a gray marbelite bottom, are there covers available for the speakers to match?

A     Answered on 4/3/2007 by Patrick P.

We spoke with Clark Synthesis and they recommend 2 speakers. Clark Synthesis stated you should place a speaker every 20' X 20' square section of the pool. You may purchase the speakers through this link and you may purchase the in wall installation kit through this link the in wall installation kit kit comes with a stainless steel face plate cover, niche and all parts to install the speaker into the niche.

from Germany ()

Pros: good performance, good prize/performance ratio

Cons: easy to break plastic parts

This underwater loudspeaker is the best in performance in this prize category I have seen yet. Above that it has the flexibility to be used as dual (under/above water) at least in small areas. However the plastic material is not very robust so you have to handle carefully.
