T.H.E. Show Newport Beach 2015 Report
The Home Entertainment Show 2015
Concert Fidelity Electronics And DIASOUL Corporation Speakers

  Concert Fidelity is here at THE Show Newport 2015 with Kotobuki Acoustics and DIASOUL Corporation model DIASOUL I speakers ($120,000 per pair). The speaker was very intriguing and uses a pure boron tweeter. DIASOUL seeks to achieve high propagation velocity and moderate internal loss at the same time. B4C (boron carbide) at a propagation velocity of 12700m/sec is faster than boron and second only to diamond, yet it possesses an internal loss similar to paper making it the ideal material for a diaphragm according to the company. Each individual tweeter unit consists of a boron dome and cone which are implemented in a mechanically coupled two-way construction and as a simple direct radiator it is a single unit. The midrange and tweeter section is equipped with four modes of high-pass and low pass filters for frequency response correction, and one can match the listening room's characteristics for optimum in room frequency response.

The midrange unit and woofer units use NCV (Nano Carbonized high Velocity) diaphragms, which are injection molded nano-carbon tubes and multiple resins. The NCV midrange and woofer drivers are said to achieve a propagation velocity of 5600m/sec, which surpasses titanium (5100m/sec) and rival the moderate internal loss of paper.

Room acoustics tuning was done by Kotobuki Acoustics. Front-end gear was by Concert Fidelity, which Enjoy the Music.com has reviewed quite a bit over the years (check our search engine for details there). My listening notes say that imaging was nearly flawless, as nothing ever stuck to the speakers. Quite impressive and a very unique design. They played a piano piece and it sounded incredibly life-like. The female singer had a gracefully seductive yet realistic sound. I can't stress enough how natural the piano filled the room, as if there was one within the room! Splendid!
