Introduced a few years ago Pioneer Japan announced the new EX series 8 premium speakers worldwide, with existing Technical Audio Device (TAD ) concept and technology.

The company decided to revive a glorious tradition and assembled an international team of engineers and designers in Paris, where involved technical department from Tokyo and the R&D department from Los Angeles participated in the process.

So powerful effort and was created eighth series, which is headed by a floor model S-81-K. These systems meet the latest requirements in terms of not only design, but also engineering solutions.

Thus, through the use of this frequency band SUPERTWEETER 4-ways acoustics extended up to 100 kHz. Externally similar to the ribbon tweeter, but actually serves as the emitter dome of superfine titanium foil, placed in a slotted socket. Its shape is designed so that the radiation pattern in the horizontal plane turned out as widely as possible. Hundred kilohertz, of course, we will not hear, but the presence of harmonics on SACD, for example, gives a sense of air and subjectively extends spatial perception. In addition, the audio formats Dolby TrueHD and DTS-HD Master Audio more demanding acoustics used in home theater. It is interesting that on the rating plate speakers, among other things, there is the logo KEF Uni-Q, so it is possible that the HF unit has a coaxial design.

Diffusers other drivers is not quite normal - they are woven aramid and carbon fibers. It is known that synthetic aramid polymer (better known under the name Kevlar) has a bullet-proof resistance and carbon fibers effectively absorb mechanical resonances. The result is a lightweight, rigid and inert diffuser, introducing much less distortion at large signal amplitudes.

All three drivers - two woofers and midrange - not only have diffusers one size (13 cm), but also carefully chosen to give a minimum of time mismatch. For the same purpose, and designed new crossovers assembled from elements of audiophile quality.

Bass reflex bred forward, has a decent diameter and improved aerodynamics. Four input terminals, bridges made of segments of copper speaker cable. At the bottom, instead of thorns - massive legs in the form of hemispheres that.
