Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

Our special and unique design differs our products from the others. We use multi layer material developed for our speakers. But also very organic sound put our products on top of the speaker list. Customization is an other option that we provide to our customers making them feel special.

What's your approach to customer support?

Customers should not hesitate to contact directly with us if there is no dealer in their region. I have to mention that we have 0 customer claim until today. In terms of product sell, we work both ways. We have dealers in some countries but we also sell directly to customers in case of no dealer.

What are your favorite tracks for showcasing the strength of your products?

  • Castelucci. The Sound of Silence. Demonstrates that the specifications are not only on the paper but also in reality. Customers feels the deep and natural bass..
  • Chantal Chamberlain. The Temptation.  Very organic human voice
  • Yello. All songs. Demonstrate that our products is suitable with all kind of music.

What other products pair best with yours?

We have been using several devices and each time we get very good results. We can mention amps: Audio Research, Dan D’Agostino, and Kondo.

About the brand

Brodmann Acoustics applies piano manufacturing principles to create speakers with a unique "Acoustic Active Principle" that uses soundboard technology instead of conventional damping materials or ports for bass management. Their cabinets are designed as resonant bodies with piano-grade finishes (including optional 24-karat gold inlays), producing spacious, concert-like sound that fills rooms naturally while delivering linear bass response without typical box-speaker distortions.

About the brand

Vivid Audio's loudspeakers feature unique, nature-inspired shapes and glass-reinforced composite materials that minimize cabinet resonances and diffraction. Their proprietary Tapered Tube Loading technology and drivers made from the same alloy (developed by former B&W Nautilus designer Laurence Dickie) work together to deliver uncolored sound that makes the speakers seem to disappear in the room.

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

Unlike the vast majority of our competitors, who simply use others' active components, we have, from inception, March 2001, designed and manufactured our very own bespoke, proprietary drive units. The resultant filter networks are ridiculously simple. By controlling the whole process, we are able to derive the exact response from each in it's system. A little appreciated advange too, is we are able to provide spare parts for an extended period.

Any vibrating device will impart that vibration to the substrate to which it is fixed. At Vivid Audio at no time do we couple drive units to the cabinet directly, each is decoupled by a carefully selected soft, 30 shore silicone, memory free O ring. In the case of bass units, we go one step futher - in addition to the decoupling O ring, each driver is apposed by another identical bass unit in a reaction cancelling configuration. Expensive, resulting in an inert cabinet. Note the lack of visible fixing harware. 

A perfect acoustic solution.

(No matter how heavy you make a loudspeaker cabinet, all one is doing is shifting the damped resonances in band. Place your ear against any loudspeaker to appreciate this. The worst case example is the ubiquitous eccentricly loaded sub woofer.)  

We strive for as lower mass as possible in an extremely stiff configuration. The lower the mass, the lower the energy strorage. The same requirement as aircraft, race cars etc. There are many other unique technologies we employ, jointly presenting the cleanest window into the music. Our web page details these.

It would be foolhardy of me to send you a short list - by definition would exclude many excellent brands of which we have no knowledge. Suffice to say: Unusually, we expend an exorbitant effort in perfecting the loudspeaker / room interface, no sharp perturbations, corners, discontinuities, etc., and the loudspeaker / amplifier interface, ensuring at the minimum impedance, the current and voltage waveforms are close to being in phase - an ideal situation. Our loudspeakers present an easy load to the amplifier. Quality rather than quantity is emphasized.
