Scopus™ Tuned Membrane Bass Traps

Broadband traps are velocity absorbers effective over a wide range of frequencies from bass through treble. Tuned pressure absorbers like Scopus traps focus performance into a narrow, specific frequency region to reduce ringing, resonances, and decay times. Use thick broadband bass traps for most of the heavy lifting; use Scopus tuned devices to surgically fix any remaining stubborn problem areas.

Measure your room and note the dominant modal decay times (e.g., ~40 Hz, ~70 Hz, ~100 Hz) in a spectrogram or waterfall graph. Choose the Scopus unit closest to that center frequency. If two modes are problematic, you can mix models or add more units at the relevant boundaries. We also offer custom tuned Scopus traps (between 40 and 100Hz)!

Start at pressure zones correlated with the problematic frequency. These can be vertical corners behind the speakers, wall–ceiling junctions, or along the front/rear walls near the midpoint of the offending wavelength. Small placement changes can matter; it's important to measure before/after to confirm improvements. As always our Design team is ready to help you navigate the complexities of using these devices.

No. Because Scopus is narrow-band, it reduces decay only around the targeted frequency. Your room retains natural energy above and below, especially when you balance Scopus with broadband panels for even response.
