High end glass speaker

The Cube S

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 S 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

Frequency response 
Below 30Hz in room (depending on room properties and positioning of speakers and listener, -6dB @ 50Hz anechoic 4pi, 12dB/octave roll off) to 25kHz (-5dB)

Typical THD 
Below 0.3% @ 96dB throughout critical midrange and treble 

Radiation pattern 
True 4pi monopole point source below 700Hz, 2pi point source above 1,2kHz, traversing in-between 

Treble (1 per channel)
(Extremely wide bandwidth, ultra-high quality tweeter with coated 35mm fabric dome. Top plate and T-yoke of the strong Neodymium magnet system are CNC machined for lowest distortion and excellent precision. Pole piece and voice coil former are ventilated into a rear chamber made of rigid metal in order to prevent cavity resonance and noise. 

Bass -/ Midrange (2 per channel) 
Specially developed proprietary 7“ Aluminum-Cone driver with low inductance linear magnetic drive due to heavy copper rings below and above the pole piece, extremely low mechanical losses, non-conductive voice coil former. Resonances and energy storage way outside passband. Very long stroke design (linear 14mm p-p, max. 22mm p-p) 

Impedance 
4 Ohm 

Sensitivity 
86dB 2.83V @ 1m (anechoic 4pi). Maximum dynamic output SPL approx. 112dB.

Power handling 
100W, short term 250W, 1000W impulse 

Crossover 
High quality Mundorf foil capacitors and air core coils in separate chamber, isolated from structural vibrations and the air pressure inside the enclosure. 

Dimensions 
Approx. 25cm x 27cm x 37cm (w x d x h) 

Weight 
Approx. 21 kg

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.”

Andrew Quint

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.
