The "sweet Spot" just got a lot sweeter! The
brand new Ikonoklast5A now uses the same mid/LF driver as
the upscale Ikonkonoklast3HO. It may be field upgraded to
the 3HO, simply by snapping on the dual membrane tweeter,
at any future time.
No additional charge for this stellar upgrade!
SPEAKER SYSTEMS THAT PROVIDE SATISFYING REPRODUCTION,
EVEN AT EXTREMELY LOW SOUND VOLUME...
In every loudspeaker manufacturer's product line, one
mid-priced model inevitably becomes identified as the
"sweet spot."- That particular model that is
thought to offer most of the benefits of the
top-of-the-line, but at a sharply reduced price.
Because Ikonoklast5 subjectively delivers perhaps 80 -
90% of the intoxicating, nearly full range,
breathtakingly lifelike sound reproduction of the
flagship Model 3, at only three-fourths the price, we
believe this is about as sweet as things get!
Also, the Ikonoklast5 is
more "forgiving" of flawed program material, or
less than stellar sounding ancillary components.
Certainly, the finest program sources, components, mated
with state-of-the-art amplification and cables would be
required to reveal the difference between Ikonoklast5 and Ikonoklast3.
For this system, we have selected the Single Membrane
Coherent Line Source tweeter and paired it with a
magnificent, ultra low mass Mid/LF reproducer, with an
appropriately matched room sensitivity profile.
The underlying key to the superlative sonic realism is
provision of our exclusive 3/4-wave transmission line
enclosure for the Mid/LF driver.
This advanced technology back loading system does what
many loudspeaker designers would consider impossible: it
enables a light weight moving system midrange drive unit
(only7 grams mms) to operate all the way down, to
below 30Hz with unbelievable power, for its diminutive
5.25" size. The system provides un-rolled-off, flat
response to near 40Hz, in a typical small room!
But, extended low frequency response is only part of the
triple length transmission line advantage.
Use of the same driver to reproduce the midrange and low
bass is significant in that it eliminates the need for a
phase distorting, stereo image degrading, reactive
crossover network, containing sound quality obliterating
capacitors and inductors.
The "zero crossover components" theme is
carried even to the transition between the Mid/LF driver
and the Coherent Line Source tweeter. The Tweeter's
unconventional piezoelectric motor automatically rejects
lower frequencies, while the Mid/LF driver exhibits a
complementary, automatic high frequency rolloff. The
output of the two drivers is thereby effortlessly
blended, using the absolute optimum number of capacitive
and inductive crossover network components: zero.
Combined with physical arrival time compensation mounting
of the tweeter and Mid/LF reproducer, the crossover-less
transition regenerates a coherent sound front that keeps
both drivers in nearly perfect phase relationship in the
crossover region and beyond. The result is a more stable
and convincing stereo image and an engaging
"roundness" to the sound of reproduced voices
When sensitive low mass drive units are directly
connected to the driving amplifier, without intervening
power robbing crossover components, good things happen to
sensitivity. This effect is enhanced by the low back
pressure transmission line loading for the Mid/LF
element, freeing it from the necessity to struggle
against the cushion of trapped air that characterizes the
more typical sealed or ported enclosures.
The average room sensitivity of 92dB indicates the system
should be easy to drive, but it doesn't tell the whole
Ikonoklast5 sounds clear and engaging when
reproducing lower sound pressure levels than other
systems with similar numeric sensitivity ratings. We
refer to this concept as downward dynamic range. It is
partly this quality that enables the system to be driven
satisfyingly, even with micro-powered amplifiers.
We offer a virtually unending selection of fine hardwood
veneer finishes, all of which "wrap around" to
include the rear of the cabinet. Standard choices include
Cherry, Mahogany, Oak and Walnut. Other species may be
selected at extra cost, depending upon availability.

How it Works
A very thin conical, metal membrane is attached at its
apex to an ultra-low mass piezoelectric motor. The sound
waves ripple lengthwise through the surface until they
reach the distance alon
