Masterpiece Regis

Regis Masterpiece

After many years of building the hugely popular and successful Regis Mk1 and knowing that due to the discontinued bass/mid driver, I would have to design a new model and try and succeed in raising the bar in terms of overall sonic qualities. No mean feat because the Mk1 is truly a reference loudspeaker in many ways.

The Regis Masterpiece was born from the desire to build a cost no object reference stand mount loudspeaker and choosing 2 very high end drive units from well respected manufacturers, namely Morel and Raal. The top of the range Morel copper sleeve bass/mid driver is exceptional in every way and the Raal ribbon tweeter is possibly the best tweeter in existence and also used in the Voltaire lll and new Opus One.

Internal wiring,  cross-over components and Rhodium plated pole connectors are chosen specifically  to match these particular drive units and honed to match this design perfectly. Complimented with Mundorf's "Angel hair" internal wadding for damping properties which significantly increase the auditory spaciousness of music reproduction.

These loudspeakers are capable of the most incredible holographic presentation,  high resolution detail and bass depth defying their size. 

These reference monitors will continue to extract more resolution and quality no matter how good the ancillary equipment is in terms of cost or quality.

Voltaire III

Voltaire III

A glimpse pre-view of our latest speaker in the Voltaire range…….

Exceptional in many ways this design has virtually no cross-over and uses drivers specially chosen and adapted to give perfect integration in a 3 way system of incredible dynamics and realism.

Low frequencies are handled by a modified Volt 12” radial bass unit which takes bass control and precision to a new level and which runs completely open with no cross-over components in the signal path or in parallel.

The midrange frequencies are handled by a modified 3” Volt soft dome unit covering the most important mid band frequencies extending up to 4.5kHz crossing over to the legendary Raal ribbon tweeter to give shimmering highs only this tweeter is capable of.

The midrange unit has a single Dueland Coherent Audio cast resistor in series to lower it’s sensitivity and with a single Mundorf parallel capacitor to perfectly integrate with the tweeter.

The Raal tweeter then uses a single series Clarity Cap CMR capacitor which can be upgraded to a Dueland cast silver/oil capacitor on request.

Internal wiring has been specially chosen and using damping control and cryo frozen to give additional purity of signal path combined with WBT pole connectors.

All these components and virtually no cross-over equates to incredible dynamics and the rendition of musical passages only heard of from esoteric and extremely expensive loudspeakers.

Voltaire II

Following on in the footsteps of Zero and Voltaire Ref 1, Voltaire II achieves greater bass extension and all the hand crafted refinement of the Robson trademark use of beautiful hardwoods and leathers in a substantially built cabinet using 25mm Scandinavian
birch ply with additional bracing and damping adding to the sonic magic this monitor is capable of.

Coupled to Track Audio’s precision base renowned for adding bass control and giving greater dimension, this loudspeaker performs as a true reference marque.

Using a critically doped 8” bass unit with high linear excursion characteristics and low midrange colouration and able to achieve very good transient stability at high sound levels.

Coupled with a highly specified and large ribbon tweeter able to crossover at lower frequencies gives this loudspeaker much of its incredible vocal clarity and refined sound.

Superb imaging and a fabulously large soundstage are just some of the qualities to expect from these monitors along with bass dynamics only Volt are able to achieve through innovative engineering and state of the art performance and design.

Burlington

Burlington Mkll

The new Burlington Mkll has taken many years to develop and a big achievement to supersede an already very popular design.

Based around a cabinet of high structural integrity using constrained layer damping philosophies in much of it's design and using possibly the best bass/midrange and tweeter on the planet with a cross-over that flawlessly integrates both drivers together.

As with all new designs we are constantly trying to raise the bar in terms of simple musical enjoyment  where you can connect with the music being played. The Burlington Mkll does this in a truly holographic nature! Stereo separation and the natural decay of notes are portrayed in exquisite detail and resolution. High frequencies such as cybils and the natural air and textures  around instruments give an astounding realism to  recordings especially live venues.

Although this design incorporates a single Purify Audio 6.5" driver for bass and mid frequencies, the level and quality of bass produced still amazes everyone. Capable of reproducing the lower octaves of music with extreme speed and authority.

Special attention was given to the cross-over design which uses specific components to match the drivers irrespective of cost. Additional damping applied to the cross-over board with point to point wiring, silver solder and internal wiring using 99.999% 5N OCC copper wire with Airlock insulation made from fluoropolymers.

Each base is made of 10mm steel with isolation coming from our Panzerholtz and ball bearing feet which has been proven to give a far superior isolation of loudspeaker to floor. It is essential to dampen the vibrations emitted by loudspeakers either through the air or via the ground borne vibrations with both equipment dampening and loudspeaker dampening techniques. Spikes and "soft" isolation feet generally do not work and can introduce various problems when connected to differing floor structures.

Both the stand mount version and the floor standing model will redefine the  possibities  from an audiophiles perspective in terms of sound staging, resolution and dynamic contrast.

Vanishingly low distortion figures are only 1 of many features these loudspeakers exhibit bringing  the listener closer to the " in real life" musical experience within your listening space than ever before.

Opulus

Opulus

 

The all new Opulus has been completely re-designed with an upgraded bass/mid transducer from Morel utilising a massive 3" Hexatech voice coil and damped composite polymer  for high power rating and low distortion. 

State of the art components and construction allow this design to operate with great speed, and precision with extended and controlled bass belying it's small size. Complimented by a Ribbon tweeter which is incredibly fast and dynamic, music flows effortlessly allowing the listener to become one with the musician.

Our new reference internal wadding "Angel hair"from Mundorf is installed as standard bringing significant improvements in the mid range frequency band. Its damping properties significantly increase the auditory spaciousness of music reproduction.

Having spent many years researching the benefits of higher quality internal wiring, binding posts and cross-over components, Opulus as with all the Robson range comes with an upgrade path to maximise on signal purity.

This incredible loudspeaker will live up to all expectations and partnering with the very best equipment will only allow Opulus to redefine musical reproduction.

Arabis

Arabis

Arabis is an ultra high end mini monitor based around  Purify Audio's ultra low distortion 4" bass/mid transducer and a Morel dome tweeter.

Although these were originally designed for near field monitoring, they are equally at home as full range loudspeakers due to the huge bass capabilities of the Purify transducers.

Incredibly low distortion,  purity of sound and detail resolution are where these monitors excel. Bass response is beyond understanding for such small loudspeakers.

Arabis are one of the new designs of high end loudspeaker models from Robson Acoustics  which now incorporate Purify Audio transducers which we believe to be amongst the very best in the world. Combined with a compact Acuflex dome tweeter from Morel to give an amazing soundstage and tonal accuracy.

All loudspeakers are handcrafted in solid hardwood which are finished in a hard wax polish. 

Cross-over design and internal wiring as always, using very good quality components and mounted on well dampened boards and using Mundorf " Angel hair" as internal dampening material. This creates a very flat response across the frequency band.

Orders now being taken with a choice of hardwoods.

The current model shown is in spalted copper beech.
