STRECKKOD BT is a bass trap based on a core of high-performance acoustic foam, which provides a base with a high sound absorption capacity, which incorporates a wooden panel that acts as a resonance membrane, improving absorption at the lowest end of the frequency range. The wooden panel also presents a series of grooves based on a mathematical MLS diffusion sequence, providing the product with a combination of absorbent zones and reflective zones that transform excess absorption of the core at high frequency into sound diffusion capacity, therefore maintaining the appropriate definition of the room.

The wooden basstraps are available with varnished 'Nordic', 'Cerise' or lacquered in white or black colors.

Acoustic techniques it includes

  • High-performance foam core with air chambers that improve its absorption capacity by 20%.
  • Exclusive design of the core that optimises the efficiency of shipping, reducing the volume by 30%.
  • Wooden resonant panel that increases the low-frequency absorption capacity.
  • Grooved design on the wooden panel using an MLS sequence, providing a degree of spectral sound diffusion (without affecting the phase of the wave) while maintaining the definition of the room.

What is the application used for?

STRECKKOD BT is the perfect solution for the control and reduction of low-frequency reverberation and reduction of standing waves in music studios, control rooms, mastering rooms, Hi-Fi, radio / television studios, etc.

They’re the bass traps to complete the acoustic treatments with STRECKKOD panels.
