Here is an excerpt from a SubTrap review published in Equipment Review by John Kotches.

Widescreen SubTrap Review

The field of home acoustics control is crowded with relative newcomers to the industry. In this field, the Acoustic Sciences Corporation (ASC) is a relative veteran, and was one of the first companies to offer products for home and professional environments to address noise abatement and acoustical control issues.

The ASC SubTrap™ made a marked difference in the bass reproduction in my room, and I got the measurements to prove it!

ASC’s best-known product was awarded U.S. Patent 4,548,292 for a “Reflective Acoustical Damping Device For Rooms.” That isn’t a very catchy name; we’re much more familiar with the product’s retail name of TubeTrap™. The TubeTrap has achieved a rather interesting position in that it is used as both a generic (as is Xerox for photocopying), as well as a specific product. ASC has evolved far beyond the TubeTrap and now offers a wide range of acoustics products for the home, studio, and professional environments. Art Noxon is president of ASC and the inventor of the TubeTrap. Art holds advanced degrees in both physics and mechanical engineering, with a focus on acoustics. His company’s product line has greatly expanded since its inception 20 years ago.

When it came time to build the dedicated home theatre/multichannel room in my new home I took the advice of a friend and fellow Widescreen Review writer Stacey Spears. It was Stacey who suggested I use ASC’s ISO-Wall solution. Stacy has a complete dedicated ASC room, including both sound and vibration proofing and conditioning. And Editor-In-Chief Gary Reber uses SubTraps in one of the reference systems at Widescreen Review.

I couldn’t have been happier with the results of this decision, and I’ve been rewarded with a room that’s free of the usual boominess that can result from typical construction. These items can be objectively verified, and I have provided a series of MRC graphs demonstrating whether or not the product meets its design criteria.

• Lifts subwoofer out of the floor pressure zone, replacing it with a pressure zone bass trap.
• Shifts ceiling feedback reflection outside upper crossover frequency.
• Improves attack transients by reducing vertical mode ringing.
