Four black acoustic foam cubes for fitting in the corners of a room, in the size you choose: 15 × 15 × 15 cm or 20 × 20 × 20 cm. The supplier lists only the 4 cubes as contents, so glue and double-sided tape are not included. They arrive compressed, and they need a few days to air so they regain their shape. They reduce echo by absorbing some of the sound that bounces around inside the room, but they do not stop noise coming from outside.

Black acoustic foam cube, 15 cm per side, on a white background

Acoustic corner panel cubes: size and material

Each pack contains 4 black acoustic foam cubes, all in the size you choose: 15 cm or 20 cm sides. The supplier does not specify the type of foam and does not state the weight. Stacked, 4 cubes cover 60 cm in height if they are 15 cm, and 80 cm if they are 20 cm. These figures are calculated from the side of the cube. The supplier advises covering the corner from top to bottom, so for a corner as high as the room, you will need more packs.

Choosing between 15 cm and 20 cm cubes

The two versions differ only in cube size: 15 × 15 × 15 cm or 20 × 20 × 20 cm, always in a pack of 4 pieces. The photos show one cube of each size, with the dimensions written on the sides. The colour stated by the supplier is black.

The 20 cm cube is larger: with the same number of pieces, it covers more wall and takes up more space in the corner. If the room is small or the corner is already filled with furniture, the 15 cm cube takes up less room. Before ordering, measure the corner and decide how many cubes you need, bearing in mind that each cube covers, in height, the size of its side.

How to fit the cubes in the corners

A cube rests in the corner between two walls, or between a wall and the ceiling. The pack does not list any glue, double-sided tape or screws: you choose the fixing method, as the supplier does not specify one. A practical tip: use an adhesive suitable for foam and test it first on a hidden spot, because a strong adhesive can take some paint with it when peeled off.

The cubes are packed compressed and may arrive thin and creased. The supplier explains that it is enough to leave them to air for a few days, or to wash them with water and dry them. Wait until they have regained their shape before fixing them.

Where to use acoustic corner panels

These cubes are designed for corners, where two walls or a wall and the ceiling meet. The supplier recommends them for spaces such as meeting rooms. At home, you can place them in the corners of a room or an office that you want to treat.

An important point: an acoustic cube reduces echo by absorbing some of the sound that bounces around inside the room, but it does not stop noise from neighbours or from the street. The supplier does not publish absorption figures, so we do not promise results: try one pack first and judge whether you need to cover the whole corner.

Frequently asked questions

How many cubes do I need for a corner?

It depends on the height of the corner. A 15 cm cube covers 15 cm in height, and a 20 cm cube covers 20 cm. For a corner 250 cm high, you need about 17 cubes of 15 cm, that is, 5 packs, or 13 cubes of 20 cm, that is, 4 packs. These are calculations based on the side of the cube. You can also cover only part of the corner, for example the area near the ceiling.

What is in the pack?

Four foam cubes in the size you choose, and nothing else: the supplier lists only the 4 cubes as contents. No glue, double-sided tape or screws are included, so you will need to source the fixing yourself. The colour is black. The supplier does not state the weight or the type of foam.

Why do the cubes arrive flattened?

The supplier packs them compressed to reduce their volume, so they may arrive thin and creased. The supplier presents this as a result of packaging, not as a defect. To help them regain their shape, leave them to air for a few days, or wash them with water and dry them. Wait until they are dry and have regained their shape before fixing them.

Do they stop the neighbours' noise?

No. The cubes reduce echo by absorbing some of the sound that bounces around inside the room, but they do not stop noise from outside. Reducing noise through a wall requires other materials and building work. The supplier provides no verifiable absorption figures, so we do not give any.

When will my order arrive?

Delivery takes 7 to 15 business days after payment; you receive the tracking number by email. The maximum delivery time is 15 business days: if it is not met, you can cancel the order and get a full refund.

Can I return the product?

Yes: you have 30 days from delivery to return the unused product in its original packaging. Return shipping costs are paid by the customer. All the details are in the return policy.
