New Rack Mountable 250 Watt Sub Amplifier and the Self-Powered 1,000 Watt Sunfire D10 Sub Rock Gives the Customer a Choice for Either Indoor or Outdoor 110/220v Power Sources

DENVER, September 14, 2006 - StereoStone, Inc. (, a leader in American -made architectural outdoor weatherproof speakers, is proud to announce that it now provides two choices for powering its acclaimed outdoor "Sub Rock" speaker systems. Both systems will be featured at the 2006 CEDIA Expo, held in Denver from Sept. 14 -17 at the Colorado Convention Center, booth 161.

"StereoStone's new rack mountable 250 Watt sub amp and the self -powered 1,000 Watt Sunfire Sub Rock give the customer a choice for powering our outdoor sub rocks," explained Alan Rottner, vice president of sales & marketing for StereoStone. "For those with a rack system that drives the outdoor subs, our new 250 Watt amplifier allows for easily changing the gain and/or setting the crossover as the amplifier is readily accessible in the rack system with the rest of the home theater components. Additionally with this system, there is no 'outdoor' 110/220 Volt runs required as speaker cable is run from amplifier directly to the subs."

Additional StereoStone 250 Watt Subwoofer amplifier specs include:
• Primary Power Switchable 115 / 230 Volt 50/60 Hz
• Rated Power Output: 250 Watts 4 ohms @ 100 Hz
• Removable 19 -inch Rack Mount Adapter

A great value, a pair of StereoStone Gibraltar and the 250w Sub Woofer Amplifier (which will drive both of the Gibraltar Subs) is offered for a total retail of only $1500, all the while attaining the renowned StereoStone audio quality.

For those audiophiles that require an integrated power supply within the sub rock itself, StereoStone also offers the Sunfire Sub Rock. This complete system includes a single, 10 -inch outdoor subwoofer that also incorporates an integrated 1,000 Watt Sunfire D10 amplifier that is fitted into a StereoStone rock enclosure which is designed to give protection to the powered internal amplifier from the surrounding outdoor elements. This system has the low frequency and volume pre -set within the enclosure and requires an additional 110/220 Volt speaker run.

StereoStone's exclusive loudspeaker design uses ferrofluid cooling technology, while also using santoprene weather resistant surround suspension and the latest poly mica cone materials. This permits greater power handling with lower distortion.
