We work exclusively with the cutting edge speakers of the ACCUTON brand market, for its High End audiophile features and its proven quality.


To control our drivers, we exclusively use MUNDORF electronic components of the supreme series, both in resistors and in capacitors and CFC for the coils. In the development of the filter divisor of frequencies, which is mounted isolated in the base of our enclosures, we take into account all the aspects that intervene in the control of the drivers. The result is a tonal balance and a clear and enlarged sound image.


All the enclosures are manufactured entirely and exclusively in birch plywood, using a 3D structure patented by bonySound called Dualbox. We use this material and no other because of the rigidity that it implements to the structure, after long tests with other materials more common in the big market.


Colors & Finishes

We want to give our products the best possible finish regardless of the chosen model or its color, for this we use the same products that are used to make musical instruments and luxury furniture, a surface with a high gloss (or matte) lacquer, polished to hand and resistant to daily use.


We give the client the possibility to decide, free of charge, the exterior finish of the enclosures, the type of wood and the color. By default, the colors are black and high-gloss white, while the sides of the cabinet can be external laminated by natural rosewood, walnut, apple or ebony wood.


Other finishes can be done on demand.

DualBox Enclosure

Think of an acoustic enclosure where the sound only comes out through the speakers and you do not hear echoes in the box or unpleasant resonances. An enclosure built by hand, made of natural wood, which incorporates the best drivers on the market and with exceptional finishes reserved for musical instruments. All this and more is Dualbox.


We bet on the R + D + i in our products, and all our engineering effort and the creativity is the DUALBOX system, a box free of resonances, with a sharp and controlled response in the bass and medium frequency. This translates into a greater definition of the sound message, to expand the scene and listen to the silence between the instruments.


The construction process is laborious and completely manual, with a final result that makes the difference.


The Acoustic Boxes as well as the musical instruments must to be tuned, therefore we tune the boxes one by one, so that the naturalness and depth that defines our HIEND enclosures flows.

The Diamond Drivers

The physical difference between the standard and diamond speakers is in the material that covers the sapphire structure in the diamond version, which is made of diamond-shaped crystallized carbon. This deposit allows the structural hardness to be raised to the current technological limit. Acoustically, it drastically reduces the resonances of the dome material, making it stable up to 33kHz or 60kHz depending on the model. The dome of the standard sapphire version is stable down to 25kHz, and this means that the characteristic sound of all dome tweeters can still be heard at a very low level. Some even of well-known brands, we can speak of breaking the dome below 20kHz, significantly increasing this sensation.

When the tweeter reaches the break-up frequency, the instability of the cone makes accurate reproduction impossible thereafter. Acoustically, how can this change be explained? First, the harmonic distortion disappears to our sense of hearing, and consequently, the sensation of feeling the tweeter also disappears. Therefore, hearing is even clearer and more realistic and more pleasant.

The substitution of these drivers for the diamond model does not affect the acoustic spirit of the loudspeaker, but the clarity of the reproduction is improved to the limits that the current technique allows.


Bonysound allows music lovers and audiophiles to access this exclusive segment of HIGH-END loudspeakers with competitive prices, matching them, and even improving on the standard models on the market.
