T.P.D.A. - Artnovion technology (Tunable Pistonic Diaphragmatic Absorber)

The ultimate combination of performance and finesse.

 

Low-frequency control is the foundation of acoustic treatment. Strong modal frequencies can be the make-or-break of many rooms, often uncontrollable without altering room structure.

 

Enter the Sub Trap - a new approach on low-frequency control - a fine-tuneable device with unprecedented performance. The Sub Trap is a new category of acoustic treatment, targetting the sub-bass frequency range. It boasts the highest absorption coefficient per volume on the market.

It employs Artnovion's latest membrane technology - a symbiosis of precision engineering and material science - creating a device that can be precisely calibrate to work at the exact resonant frequency of a space. T.P.D.A.

 

The Sub Trap is composed of 4 independent cavities - 3 sealed volumed equipped with independent, tuneable diaphragmatic membranes (T.P.D.A.), and an additional acoustic core packed with a high-performance porous absorber (V.A.B.T.). This configuration is designed to bring you the best performance possible, with pressure and velocity sensitive cores exposed to the correct modal areas.

 

Outstanding tuneable performance. Issues under 60Hz are common, and can be tricky to solve. Usually structural alterations - such as lowering ceilings, or dedicating huge portions of the room to bass trapping are required.

 

Here enters the Sub Trap, Artnovion’s latest addition gives you the chance to keep your home as it is - and tune it to exactly what you need – with a panel that attenuate room modes from as low as 40Hz.The Sub Trap takes a new approach on absorption, using a new membrane technology akin to a speaker cone, suspended a calibrated mass on an elastic surround - allowing for a much superior - and controlled - performance. A further feature is the possibility to precisely tune the membrane to resonate at your desired frequency by simply adding or removing mass from the membrane (TPDA).

 

The Sub Trap can either be installed in corners, or feature as a stand-alone unit. Integrated Fixing System, already incorporated on the panelThe exterior of this colossal panel is clad in exquisite hand-crafted wooden grills, available in select finishes.

 

Performance - Use the Sub Trap performance chart to estimate the number of units required to achieve different dB reduction levels in certain room sizes.

Efficiency - The positioning of Sub Trap units relative to the mode shapes is extremely important.
