(2 Pack) Triangular Corner Bass Trap 42x42x42cm Black SCIFI - LowFreq

In this review the reviewer examines the (2 Pack) Triangular Corner Bass Trap in Black SCIFI, a purpose-built corner treatment aimed at rooms where low frequency control matters. The bottom line: it is best for home studios, rehearsal rooms, and small auditoriums that need targeted bass absorption and some diffusion without a full renovation. The reviewer found the traps effective at reducing corner build-up, simple to position, and visually discreet, delivering clearer bass response while fitting into typical room decor.

Key Features

• Corner bass trapping: The triangular pyramid shape concentrates and absorbs low frequency energy where it accumulates in room corners, tightening bass response.
• Absorption and diffusion: A laminated MDF plate paired with acoustic foam provides both absorption and scattering between 63Hz and 1000Hz for balanced low to mid control.
• Generous dimensions: At 42x42x42cm overall with 210mm thickness, each unit offers deep broadband performance that outperforms thin panels for bass.
• Fire safety: Constructed with type M1 foam and rated Euroclass E for fire behavior, making it suitable for many commercial and home environments.
• Pack of two: Supplied as a box of 2 units so one purchase covers two corners or a pair of reflected positions for symmetrical treatment.

Who It's For

The Triangular Corner Bass Trap is aimed at musicians, audio engineers, and serious hobbyists setting up recording studios, home theaters, or rehearsal rooms who need to control low frequency build-up in corners. Its size and scattering range make it a practical option for rooms where standing waves and muddied bass are audible issues.

It is less suitable for buyers who want an all-in-one room overhaul or need FDA or higher fire ratings for strict commercial installations. Those who prefer modular, lightweight panels for temporary mounting may find the supplied mounting options and tape quality mixed in user reports, so plan the installation method ahead of purchase.

Pros & Cons

Pros

• Clean, unobtrusive triangular design that integrates with studio and home theater decor.

Frequently Asked Questions

Can these be mounted on the ceiling as well as corners?
Yes. The traps are intended for wall or ceiling installation, but secure mounting hardware is recommended over self-adhesive tape for ceiling use.

What frequency range do they affect most?
They are designed to absorb and scatter primarily in the low to lower mid range, roughly 63Hz to 1000Hz, improving bass definition.

Are they safe for commercial spaces?
The units use type M1 foam and carry a Euroclass E fire rating; check local regulations if a higher fire rating is required for your venue.
