TubeTrap: The Original Bass Trap

TubeTrap - IsoThermal Bass Trap

The original corner loaded bass trap, TubeTraps are cylinder shaped for strength and come with a built-in treble range diffuser.  Unlike membrane or resonant bass traps, TubeTraps are extremely fast because they are impedance matched to sound waves.  They easily handle unwanted bass energy buildup from transients as well as from sustained tones, and reduce mode coupling.  They enhance room ambience while improving transient dynamics.   TubeTraps deliver an unforgettably articulate, musical bass line. 


The TubeTrap's claim to fame is its unrivaled ability to absorb low frequency sound energy.  After its release to the public, it quickly became the de facto standard for acoustic room treatment.  Generally set up in the corners of the room where they act like sonic shock absorbers, TubeTraps eliminate excessive build-up of bass energy in the room while their built-in diffusers minimize flutter echo by horizontally scattering mid-high frequency sounds to provide fine grained lateral ambience.

Art Noxon, Inventor of the TubeTrap and Founder of ASC explains the TubeTrap and how they work:

How It Works

TubeTraps, the original, archetypal bass trap, dating back to 1984, are set up in the corners of the room where they act like sonic shock absorbers. TubeTraps eliminate excessive build-up of bass energy in the room while their built-in diffusers minimize flutter echo by horizontally scattering mid-high frequency sounds to provide fine grained lateral ambience.

The TubeTrap was developed using acoustical engineering principles and voiced by the consensus of "golden ear" audiophiles and engineers.  It was the first full bandwidth sound absorber/diffuser (abfuser) and has become synonymous with quality listening and performing spaces.  TubeTraps quickly became the worldwide defining icon of high performance audio room acoustics, and remain so to this day.

TubeTraps are used to make music from the beginning to the end of the audio chain.  In the recording studio, TubeTraps are used to control the acoustics that surround the talent and mic during the creation of audio tracks.  Next in the process, TubeTraps work to create crystal clear mixing environments.  After that, TubeTraps are used to create the perfectly translatable acoustic environment needed for song and album mastering.

Benefits

Sonic Benefits 

The TubeTrap is designed to absorb sound energy when in the presence of bass range sound pressure.  The higher the pressure, the more energy is absorbed. Bass pressure is 4 to 8 times stronger in the corners of the room than away from the corners.  TubeTraps are usually stacked floor-to-ceiling in columns in all four corners of the typical audio room. Each corner acts like a giant megaphone in reverse, compressing incoming sound waves into the narrow volume at the root of each corner of the room. This corner compression of bass waves creates the perfect location for a pressure zone bass trap: the TubeTrap.

 

Models

ASC has been and continues to be the sole manufacturer of TubeTraps since their inception in 1984.  TubeTraps, other bass traps and a wide assortment of over 100 specialty audio acoustic products and devices can be purchased factory direct.

Every standard TubeTrap comes with a 30 day, 100% satisfaction guarantee. If you don't like it, send it back and we'll refund your money, no questions asked.

We manufacture a wide variety of TubeTraps and every one of them is hand made by hand in our own 10,000 sqft workshop in Eugene, Oregon. Each product is air tight and fiber sealed and fits an exact acoustic and physical specification.

Customization

In addition to the wide variety of standard TubeTraps available, we provide an even wider variety of modified TubeTraps. Some modifications are superficial, belonging only to the appearance of the TubeTrap. Other modifications are internal, in which case they are fit with some sort of performance enhancing feature.

It is not unusual for a room corner to be acute or obtuse. QuarterRound TubeTraps can be altered to accommodate such situations.  Fractional TubeTrap (HalfRound and QuarterRound) end caps can also be installed at various angles so the units can be butted together to follow an irregular wall shape.  TubeTrap technology can be used to create "black acoustics" of nearly any shape, to be hidden behind stretch fabric, furnishings, or any other out-of-sight location which is also a high sound pressure zone.

We often add absorption enhancing elements inside what appears to be an ordinary TubeTrap.  The most common upgrade along this line is the SuperTrap,  where the operational volume of the TubeTrap is increased by 33%. This modification extends the roll off frequency of the TubeTrap ½ octave lower, and is available in all diameter models of TubeTraps.
