Aquasonic Underwater Speaker Installation
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.

In-wall installation of the underwater speaker requires a parts kit which is sold separately. For the Aquasonic Underwater Speaker In-wall Assembly Parts Kits, click here.

How do I know how many speakers I need for my pool?

A  Answered on 11/28/2006 by InyoPools Product Specialist Patrick P.

For ideal sound transmission, the manufacturer recommends using one speaker for every 20' x 20' section of pool.

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 InyoPools Product Specialist 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.

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 InyoPools Product Specialist 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.

What is the maximum depth for this speaker?

A  Answered on 8/6/2008 by InyoPools Product Specialist 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.

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

A  Answered on 4/14/2009 by InyoPools Product Specialist 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.
