The Epicure Eleven, a step closer to reality
The Epicure Eleven, the ultimate bookshelf speaker, incorporates superior linearity excellent dispersion and nearly perfect system phasing. The Eleven delivers flat, undistorted linear frequency response from 38 to 20,000 Hz.
To achieve concert hall clarity ina compact speaker, the Eleven combines, in a ported system. Epicure's celebrated 1-inch air-spring tweeter and a specially fabricated controlled-excursion 6-inch low mass woofer. The tweeter provides unparalleled power response in the mid and upper ranges. In fact above 1800 Hz, nothing in the industry is capable of finer performance.
The key to the Eleven's overall superior sound is the unique relationship - a mathematical one, computer-calculated - between its 6-inch woofer and its bass port. It's not difficult to produce superb mid-range power response and dispersion with a driver this size. But to achieve those qualities in a compact speaker, and at the same time reproduce the earthshoking tones of the lowest bass frequencies, has never before been accomplished.
The sophisticated engineering design of the Eleven works in this way. From its crossover frequency at 1800 Hz to as low as 100 Hz, the Eleven's 6-inch woofer produces dynamic sound and dispersion by itself. Below 100 Hz and continuing through to as low as 38 Hz, the bass port - in essence an audio-active tube of air critically aligned within the speaker - serves to augment the power response of the woofer. So that those deep, fundamental tones normally unavailable to a driver this size become available. The total effect is total sound, concert hall realism from a speaker small enough to fit on a bookshelf.
The Epicure Eleven Tweeter
Here is a 1-inch, air-spring tweeter unlike any other in the industry.
There's a balanced, low-mass voice coil assembly. Not centered semi-perfectly, but centered perfectly. And not fixed with the usual silicone, but rather with a vastly superior substance, a space-age fluid that no one else in the business uses. The result is lower distortion in the midrange, particularly noticeable in the voices. And the tweeter produces nearly hemispherical dispersion across most of the audible range.
The Epicure Eleven Woofer
The Epicure Eleven has a specially fabricated controlled-excursion 6-inch low-mass woofer. Its low-vacuum deposit cone is light and stiff.
The woofer often remarkable openness and dispersion. The result is a smoother, more accurate bass without the usual resonance and hooviness of the low notes. This woofer makes it possible to really hear individual bass instruments not just "bass".
