The JS1 Bass Trap is a refined acoustic treatment designed to bring precision and warmth to your listening space. Its original design strikes a balance between traditional triangular and square traps, achieving equal to improved low-frequency absorption in a smaller footprint. At just 47" H × 18" W × 14" D, the JS1 is compact yet powerful, making it an excellent companion to specialized treatments in both dedicated studios and casual living spaces.
Built from locally sourced white ash, fiberglass insulation, and a thick felt covering, the JS1 combines acoustic performance with natural materials for a modern, approachable aesthetic. The felt exterior enhances absorption while the ash detailing ensures it fits seamlessly into a room without feeling intrusive.
Performance:
- Optimized absorption under 200 Hz when placed behind speakers (with two units)
- Targets low-mid and bass frequencies (<800 Hz) to reduce muddiness
- Decreases midrange echoes (250–800 Hz) for improved clarity and warmth
- Improves decay times across all frequencies, amplifying the effectiveness of other treatments
- Higher absorption coefficient than competitors in real-world testing, especially in the low-mid and upper bass ranges
For best results, corner placement of multiple units is recommended. With only two traps, positioning them directly behind speakers delivers the greatest impact on low-frequency control.
