Peak Consult Perspective for The Kepheus

In the jungle of consumer and so-called High-End loudspeakers, there are some brands actually reaching for these higher goals. Peak Consult is one of them, but how is that done?

Countless hours of measuring and critical listening by many audiophile ears have gone into making The Kepheus one of the finest three-way loudspeakers available. With impedance curve and electrical phase characteristic like an electrostatic speaker, the final blend of art and technology has made The Kepheus an uncompromising work of art. The State of the Art and the finest loudspeaker have seen the light of day. It will herald a new meaning to High End speakers.

The multifaceted enclosure of The Kepheus is handcrafted in our own facilities in Denmark by skilled Danish artisans in a 1.5"- 3.0" HDF specially glued sandwich material covered by 1" solid acrylic. At all points, resonance suppressers have been used in the construction. Special resonance suppressers have also been milled into the construction. Each material panel has been measured and hand-chosen by skilled Danish artisans. The triple order composite creates a new standard in resonance control. The Peak triple construction renders resonance problems virtually history. Production is very costly, but Peak Consult made that final step.

The design optimises the off-axis response and minimizes any kind of diffraction. In order to minimize acoustical waves, there are no parallel front, back, top or bottom panels. The slant of the front panel aligns the phase and timing between tweeter, midrange and woofers. All design choices have been made and done to meet acoustical performances. The enclosure is the direct result and the acoustical phase behaviours are second to none.



The Tweeter:
The tweeter is a triple magnet 1" soft dome with a non-resonant aluminium chamber. It features multiple chambers with low compression and a machined aluminium faceplate. Peak Consult has altered the front plate in a very different way to take the perfect behaviour to the extreme. The tweeter performs effortlessly at the sonic extremes and creating "space and air" unlike all previous dome tweeters. The most important thing about the choice of this construction was the performance. There are many tweeters reaching for the higher frequencies, but they fail in phase characteristics and that is what it´s all about. Not data - only performance.

The Midrange:
The dual 5"Audio Technology midranges are hand-built specifically for optimal behaviour in The Kepheus enclosure. The driver features a cone that has been uniquely shaped for this moving system and a vented magnet system that includes Symmetric Drive, optimising the linear directivity. It performs with unparalleled sound staging ability and images as tight and sharp as a diamond. The midrange will set new standards with regards to midrange clarity and will go far beyond what is typically possible for a midrange driver.

What has been done? Peak Consult choose to have a very linear and stable cone, instead of fancy cones that in Peak Consult ears are unreliable in production as well as performance. The chosen cone is more coherent instead vs. the unnatural excesses of popular exotic cones. Furthermore, Peak Consult have decided to do the most linear design that makes the speakers perform effortlessly in years to come. This was an easy choice, instead of choosing an exotic appearance.

The Woofer:
The dual 6" Audio Technology woofers are hand-built and specifically designed for The Kepheus. Using new and special technology in the moving part of the units make them very low-loss drivers. The huge magnets and ventilation that includes Symmetric Drive systems make the driver´s reproduce very tight and extremely low frequencies - second to none. These drivers will set new standards in bass reproduction.



High frequencies:
The Kepheus includes an acoustical fully compensated second order crossover in the tweeter/midrange and woofer section, isolated from the moving system in its own dual sealed department. The Kepheus only features the best of the best. Dual Peak foil capacitors, silver carbon resistors and oiled/waxed inductors by Duelund Coherent Audio manufacturer of the world´s finest components.

Low frequencies:
The low frequency includes only oiled/waxed-foiled inductors from Duelund Coherent Audio helping to realise a fully compensated second order roll of. The low frequencies have also been altered by our straight level impedance and phase control. All sealed in its own isolated compartment.

Every component has been chosen for its sonic and musical behaviour, with no consideration for cost. The crossover is crimped and hardwired with silver soldering. The crossover is sealed in its own compartment to avoid microphony distortion and to shield it from electrical and magnetic radiation from the rest of the system. Peak Consult uses only the best parts to do this High End loudspeaker. Imagine, there is used more than 300 metres of components in a speaker. The end user only has control over a few metres of speaker cable. The speaker has a heart and for that only the finest is acceptable.

Internal wire:
Peak Consult uses a special dual Silver flat silk insulated OEM wire from Duelund Coherent Audio for the upper frequencies and a special Peak Consult manufactured high current cable for the bass.

The true Bi-wire termination is done with The WBT platinum signature.

Recommended room size:
From: 20 square meters and up.
