Perf Trap

Perf Trap

$269.00 AUD

The Perf Trap is a broadband low-mid frequency resonant absorber, targeting frequencies below 200Hz with a peak absorption at the 80-100Hz range.

Like the V Trap, this product is suitable to treat low frequency energy (room modes, standing waves, etc) which cannot effectively be controlled using standard acoustic panels.

Suitable for:
Critical listening spaces such as professional recording and production studios, mastering studios and high end HIFI rooms and home theatres.

Plywood frame, sealed perforated ply face, sealed ply backing
Fabric wrapped front and sides, sealed ply backing

1222x594x250mm (+/- 3mm)

Estimated 60 to 110Hz, centred at 90Hz. Wide Q

20m3 = 2x traps
30m3 = 4x traps
40m3 = 6x panels

Wait times: Our Traps range are mostly pre-constructed and generally take between 1-2 weeks depending on supply and demand.

High performing low/mid control with a wide Q.

The Perf Trap is a fully enclosed plywood box filled will polyester insulation and a perforated face. It is our physically deepest product coming in at 250mm, but with that comes a punch. It has an exceptionally large Q and plays a large role in treating critical listening spaces.
They come as an exposed or fabric wrapped option, are professionally made and can be hung in various positions with our available hang-kits, or simply stacked on top of one another. They are most effective at room boundaries where the sound pressure of a given frequency is highest.

Note: It is worth considering that this guidance is general as low frequency interactions are often complex in normal rooms. This may require a more detailed assessment in order to maximise the performance of the products and the space as a whole.
Please refer to our services section for more information.

Matched Design

Frame or fabric wrap finish options to match out V Panel range.

Damage Free Install

The Perf Trap can simply stand on the floor or be stacked against a wall.

Essential Product

Bass trapping is critical for professional mixing and mastering rooms. Most small rooms will have low frequency issues.

Fire Retardant

Fire retardant cotton drill fabric and core poly insulation suitable for commercial and residential applications.

Responsable manufacturing

Made mostly from recycled or natural materials and are all locally sourced. Made in Melbourne.

Professionally made

Handcrafted with years of experiences, Verbox products are presentable, effective and affordable.

True low end reduction

Strong and focused modal rings in a room distort our judgement of low frequency information. The perceptual effect of this is a smearing of transient information for instruments such as kick drums and bass guitars. The Perf Trap is specifically designed to tame these modal issues targeting this common frequency range.

Solid Construction

All of our Traps are ribbed internally for stable integrity to ensure effective low frequency absorption. This also keeps the weight as low as possible so the units are easily manoeuvrable.

Targeted approach

As the performance of most broadband treatment tends to taper off at around 100Hz, a targeted resonating absorber such as the Perf Trap provides a far higher amplitude reduction, diminishing strong and focused modal rings in a room.

We offer a wide range of products to suit a variety of listening environments. To best help you decide what you need, the simplest way is to email us ( with the following information.

  • Photo’s, room dimensions and details of the surfaces areas

  • Your ideal budget

  • Your location (will effect recommendation if not in Melbourne)

  • What the room is being used for

  • Any preference of colour or panel style (fabric wrapped/framed)

  • In need of installation or not

  • Room test data (waterfall graph etc) if you have it - not essential

With this information, we can provide a general recommendation for your room. Depending on your budget, location and your confidence with the process, we may offer a free site visit. Although we do recommend when possible for us to come out and test your rooms frequency response to get a more detailed assessment of your room. You can purchase this in the services section under ‘Room test and analysis’.

We also offer a range of packages under the ‘Packages’ section. These are discount packs to suit most small, medium and large rooms.

Verbox products are made to an exceptionally high standard using very high quality materials. We use a heavy cotton drill (yet still breathable) fabric, polyester acoustic batts (custom made for Verbox and E0 emissions rating), structural ply and MDF boards (also E0 emissions rating) and use bracing on all of our products when necessary.

However, they are still subject to damage by in-proper use and care. So we suggest you take the following precautions.

  • Wipe fabric surfaces with a clean, damp, lint free cloth to remove any dust. Blowing with a blower or vacuuming is also fine but less efficient.

  • DO NOT hold products from the front fabric face as your fingers around the frame can stretch the fabric.

  • For products that have rear support bars: only hold from one end of the bars where they join the panel. DO NOT hold them from the middle as they can easily pull apart. They are only there for additional support and are structurally sound if used correctly.

  • Also for products with rear support bars: when DIY installing, you must use 2x hang points (screws) to hang from on the wall and they must be 500mm apart (Lite Panels are an exception and can be used with 1x screw if you wish). Hanging too close together or just from 1x screw will result in the bar pulling apart from the panel. Again, this is normal and is not an issue if used correctly. Refer to the ‘Step-by-step Guide’ on the ‘Wall Kit’ product page for more information.

  • Do not stack heavy items on V Panels as they are not designed to hold a lot of weight and it may sag the fabric. The V Trap and Perf Traps are an exception but just use common sense.

  • Keep all Verbox products in a dry, dust free space to avoid general wear and tear. Avoid moving and dragging fabric wrapped products on hard or rough surfaces as it will scuff the fabric and could potentially tear.

  • Avoid bumping or knocking ply framed products as the ply is softer than other woods and will mark easily.

  • Avoid puncturing V Traps and Perf Traps as they are designed to be completely sealed and will lose their effectiveness.

  • Avoid placing products in direct sunlight to avoid fabric fading.
