Product description

The OS1 Bass Trap achieves the same powerful low-frequency absorption as our JS1 Bass Traps, while introducing enhanced midrange diffusion beginning at 1200 Hz. Thanks to its internal baffling system, the OS1 not only reduces muddiness in the bass range but also breaks up midrange reflections, maintaining a natural, lively character in your room.

Crafted with a blend of durable and natural materials, the OS1 combines performance with refined aesthetics. The back and face plates are MDF with a Cherry veneer, while the top and bottom plates are made from locally sourced Pine. Inside, fiberglass insulation and a thick felt layer maximize absorption, ensuring both deep bass control and smooth midrange behavior.

Performance:

  • Deep bass absorption comparable to our JS1 Bass Trap
  • Midrange diffusion starting at 1200 Hz via internal baffling
  • Targets sub-800 Hz muddiness for tighter, fuller low end
  • Reduces decay times across the spectrum while preserving energy in the mids
  • Enhances clarity and balances other room treatments without over-damping

Key Features:

  • Materials: MDF with Cherry veneer (back and face plates), Pine (top and bottom), fiberglass insulation, thick felt
  • Internal baffling for advanced diffusion of midrange frequencies
  • Dual-function design: bass absorption + midrange diffusion
  • Optimized for studios, hi-fi listening rooms, and home theaters

Test Results

The bass trap targets absorption in the low-mid and bass range, significantly improving muddy sounding audio under 800Hz and decreasing mid-range echoes from 250-800 Hz, heightening warm and full audio quality. Although designed to target these lower frequencies, it reduces decay times at all frequencies, amplifying the effectiveness of other potential room treatments. The absorption coefficient of the bass trap is higher than competitors tested in the same environment at the majority of frequencies calculated. This positive difference is most pronounced in the lower low-mid and upper bass ranges.
