High end glass speaker

The Cube T

Unique glass enclosure structure free of vibrations and cavity resonances in the air volume throughout the bandwidth of the bass-/midrange driver; results in unparalleled purity and precision of sound.

The Cube T Speaker

As a longtime specialist for glass design we have joined efforts with international audio experts and proudly present a glass speaker system which is not only a visual highlight but plays at the top of the high-end audio league. By employing a specially developed holistic concept that is sonically optimized in every possible way, glass has become the ideal structural material for this revolutionary high end audio solution. Sound and appearance unite to a unique symbiosis that redefines the state of the art – not only when it comes to design.

Facts

Glass enclosures
Glass has three excellent properties for utilizing as cabinet material the stiffness, the density yielding inertia and the neutral reflection of the audio wave on the glass without coloration. It has however one horrible property energy storage and ringing. 

Force canceling drivers
By directly coupling the magneticstructure of the drivers we can virtually eliminate vibration transfer to the cabinet and using the SSG (Super Silent Glass) philosophy we can even further eliminate vibrations.

Placing the drivers optimally in the enclosure and paying miniscule attention to the dimensions of each compartment we can push the resonance modes up way outside the passband.

Internal modes pushed x8 and x16
As an example moving the midrange driver placement as little as 1 cm in one dimension would lower the push from 8x to 4x.

Custom drivers
Developing custom drivers for the midrange with components like titanium voice coil former extra long stroke voice coil keeping it in the magnet gap super stiff aluminum cone with first cone resonance way outside the passband.

The magnetic motor assembly utilizes copper elements to minimize non-linear distortions.

The subwoofer also utilizes similar technics.

X-over and cabling
The x-over frequency was wisely chosen at 900 Hz to be in the optimal x-over band 900-1600 Hz and taking into consideration of the passband for the midrange compartment.

The X-over components used is top line Mundorf chosen after extensive listening sessions.

Omni-directional bass AND mid-range with a cardioid like super wide tweeter.

What the listeners say.

Michael Fremer, The Point

“Also outstanding was the sound in the Perfect 8/Ypsilon/Bergmann turntable room. I played "Mood Indigo" from Ellington Masterpieces and the presentation was holographic and tonally right on the sonic money, which was fortunate since the speakers alone cost around $150,000.”

Greg Weaver, Senior Editor, Positive Feedback

"This system had the ability to recreate the scale of the music in a remarkably accurate manner, yet it was able to serve up the nuances and subtleties with uncanny, unnerving realism. This system very nearly breathed life into the music it reproduced."

Larry Greenhill, Stereophile

"All of this design would be of no importance if the sound produced were deficient. I was prepared for, well, I don't know what. I was stunned to hear utterly transparent sound, with the clarity and lucidity of the original Quad's midrange. Selecting "The Mooche" from Stereophile's Editor's Choice CD, I heard the best sound I've heard from all the different loudspeakers on which I have auditioned this recording - while the asking price is other-worldly, so was the sound."

Marc Phillips

“The Perfect8 The Cube doesn’t sound like any other speaker I’ve heard, so I don’t expect it to fall in line with my expectations. I love The Perfect8 The Cube because of its uniqueness, the soundstaging and the imaging that seem impossibly vivid, and the low frequencies that are low and truly satisfying. You know I want to review these. BADLY.”

Most Coveted Product - Perfect8 Technologies Cube-T loudspeaker. The glass enclosure gets your attention but it’s the sonic transparency and authority that keeps you coming back for more. Especially having heard this new model, I really, really, really want to review something from this manufacturer. Is that enough “reallys,” Robert?

Perfect8 Technologies $60k Cube T quasi-omnidirectional floorstanders driven by Ypsilon electronics were boxlessly open on a cover of The Eagles’ “Desperado” and very very good on female vocals. “This is a contender,” I wrote in my notes. An Oscar Peterson album sounded superb in the midrange and upper octaves, despite a little room muddle at the bottom on Ray Brown’s bass. Detailed and open with a wide soundstage, the Cube T was rather like a stat with greater image solidity.
