The Scopus™ Tuned Membrane Bass Traps are precision tools for low-frequency problems you can’t fix with broadband absorption alone. Each unit is narrow-band, pressure-based, and factory-tuned to target specific modal trouble spots—think stubborn peaks and ringing that blur definition and mask detail. Use Scopus to knock down the exact frequencies causing longer decay times (e.g., 40 Hz, 70 Hz, 100 Hz), then let your broadband traps do most of the heavy lifting. The result is tight, articulate bass that translates.
