»Rondo« project A23 had a break in speaker developing. It was not
resulting in a lack of further ideas, rather the contrary is true. A
two-way project was planned and the ideas were transposed into
prototypes. We learned that we are getting more this and that in
different aspects, but it was payed with the loss of the intoxicating
coherent sound picture the Rondo is able to paint. So we continued the
widerange-road and focussed another project of our hearts.
before music reproduction was considered an aspect of entertainment
electronics, reproducing music involved the use of high efficiency
speakers and low output power amplifiers. This was all that was
available at the beginning of Highfidelity, which predated stereo.
Anyone who has heard these distinctive components from the early
history of our field has no difficulty understanding our passion to
find or develop products today that exemplify the same, all too rare
qualities of design and sound. That is our quest: not to recreate the
past, but to find current implementations of the spirit, insight and
genius of the original creative giants when it really was all about the
Our commitment to these ideals and values is now realized
in the SoloVox loudspeaker. The first in a new, and unique line of
loudspeakers under the appropriate name "Hommage" SoloVox, as does the
entire Hommage line, represents a modern implementation of the
principles and standards that defined the greatness of audio
reproduction in the first half of the previous century. SoloVox
loudspeakers are produced in limited numbers reflecting a commitment to
produce the very best possible component and to highlight their
uniqueness. These are not loudspeakers intended for everyone, and they
do not represent a mass market effort to make yet another loudspeaker.
The SoloVox is anything but just another loudspeaker.
new breakthrough product, the SoloVox is the result of years of design
work. We at Auditorium 23 have been engaged with the French company
PHY-HP since 1997. Until now, most our speakers have been based on the
PHY-HP model H21 LB15 driver. Judging by the success among music lovers
and the press of our various speaker models all employing this driver
Appassionata, Provence and RA 605 - it's certainly no overstatement to
imply that Auditorium 23 has created with its different widerange
concepts the rising popularity of full-range drivers in dipole
speakers display the technical and sonic advantages of the open baffled
design while overcoming a number of problems normally associated with
this approach. However good these designs were, they were not without
their limitations and distinctive problems - as any other concepts in
the trade. All of these models were relatively large and when placed
close to the wall in smaller rooms, they sometimes had difficulty
sounding as free and airy in their musical presentation as they are
otherwise capable of. Nor could we offer a useful solution or
recommendation to this problem at the time. Instead of the airy, open,
relaxed sound that these speakers were capable of in most rooms, the
21cm driver could sound a bit caged and closed in.
to circumvent these problems ultimately led to the development of the
SoloVox, a loudspeaker whose unique and legally registered rear
radiation flow-pattern creates an increasingly airy and open
presentation even when placed close to the rear wall: previously
unheard of performance in an open baffle design.
The SoloVox is
capable of the most extraordinary, life-like, natural and unforced
music reproduction with the amplifiers of the most modest output power
and they can do this with an ease of placement in moderate sized rooms
that is was only recently taken to be unthinkable in an open baffle
design. The SoloVox brings all the distinctive virtues of the open
baffle to all listening rooms.
The uniqueness of the SoloVox extends beyond this major breakthrough in ease of placement in reasonable listening rooms.
SoloVox cabinet design unites the advantages of acoustic baffle and
closed housings and achieves optimal utilization of the sound energy
radiated to the rear.
- Ordinarily troublesome diffraction effects of the sound waves radiated forward are reduced by the shape of the acoustic baffle
proportions of energy radiated rearward are dispersed by specially
formed elements allowing a positioning near the wall in smaller rooms.
laterally radiated sound waves join the forward ones in ways that
literally make the enclosure disappear. Music is played as if in space
before you and not from speakers: the ultimate "disappearing" act.
