The premium VELVET VL42 loudspeakers are designed and handmade in Italy in the heart of the city of Milan. These high-end loudspeakers are designed specifically for audiophiles, professionals and discerning customers in the Hi-Fi segment.

They are the result of the UBSOUND passion for audio born in 2011.

You will be fascinated by the overall performance of your new UBSOUND Velvet loudspeakers.

The excellent sound performance of these loudspeakers originates from the implementation of the exclusive High Definition Natural Sound Signature (HDNSS) technology invented, designed and developed in Italy by UBSOUND.

The formula of HDNSS acoustic technology is based on several criteria and related algorithms, part of which are confidential and not disclosable. In the design process, the acoustic engineering of HDNSS technology emphasizes the physics and acoustic-dynamic approach rather than an electro-acoustic approach, as other brands tend to do. UBSOUND firmly believes in a better acoustic result thanks to the help of this technology, restoring a more natural harmony and an experience which seems more analog rather than digital.

The HDNSS technology studies rely in part on the theories of the mathematical physicist Manfred Schroeder regarding the internal resonance of the loudspeaker and its soundproofing.

One application of our technology is in relation to the soundproofing of the internal wooden panels of the loudspeaker, for which specific sound-absorbing coatings of different sizes, thicknesses, angles and materials have been used.

The perfect sound does not exist, but with this exclusive technology UBSOUND has been able to create a pure, natural and balanced sound. A sound that succeeds in reproducing an impressive amount of sound details with high fidelity, while retaining a slightly warm tone thanks to the exclusive implementation of the 45° curved asymmetric bass reflex that plays a fundamental role in the homogeneity of the propagation of low frequencies below 200Hz. This generates an excellent listening soundstage.

The goal of HDNSS technology is to create an excellent natural and high definition acoustic signature, hence the acronym “High Definition Natural Sound Signature“.


Based on the principles of this technology, we define our loudspeakers as “designed by sound“, that is to say the structure, design and materials of the loudspeakers are simply the result of what is really needed to achieve the desired acoustic signature, without any compromise. Those are the real technical-acoustic, acoustic-dynamic and electro-acoustic needs for a better listening performance.



The wooden external of the loudspeakers is finished with a special multi-coat paint, strictly hand applied with a paintbrush and the use of high quality paints. Every single detail is the result of accurate processing and selection of premium materials. A unique, attractive and minimal design, an unmistakable urban-style look that adapts to any furnishings.

They are high performance passive loudspeakers compatible with all amplifiers with a maximum power of 100W per channel at 8Ω impedance.


The UBOUND Velvet Series passive loudspeakers can be used with digital amplifiers, integrated, analog, valve tube, classic or class-A, high current, standard 2-channel stereo systems, compact systems and 5+1 systems using the two Velvet loudspeakers as front monitors in the left and right channels. They are also suitable for the “pure direct line” system (no equalization) available on some amplifiers; also suitable for those who simply want to replace their home hi-fi system loudspeakers in order to achieve significantly better sound performances. Suitable for both professional and domestic use for the most demanding users.
