always heartened to see individuals pushing the envelope and
trying new things. A good example is the Granada Loudspeaker
from The Lotus Group that combines a super-exotic (and super-expensive)
Feastrex field-coil driver in an open baffle with a DSP crossover.
The design was radically different, but so was the sound--completely
natural, relaxed, and "un-hi-fi-like." I could have sat
and listened to this system for hours. We're thankful for
individuals who pursue their dreams and build (and demonstrate)
new technologies and approaches--they are the ones who keep

it was at CES, the Lotus Group Granada was a model of neutrality.
Even though it was digitizing analog sources via its DSP crossover,
it still managed to reproduce Joan Baez’s voice and guitar
on “Gospel Ship” with exceptionally natural timbre. Oh, maybe
it was subtracting a little bit of the most delicate tremolo
from Joanie’s soprano, but it wasn’t subtracting anything
else. What it was doing that so many other speakers weren’t
was sounding flat, uncolored, and utterly coherent. This (two-way)
speaker (using the marvelous Feastrex cone from Japan, augmented
below 200Hz by a couple of Acoustic Elegance woofers) needs
a review in TAS. Robert named it “Best of Show” at RMAF (and
I named it a runner-up), and it was a strong contender again

value of a loudspeaker to the listener can be judged by
the extent that it brings a recording into the present.
It must not only recreate the illusion of the space the
recording was made in, it must make that space believable
and rock solid. It must deliver a palpable sense of the
musicians' presence and show us plainly the intent and nuance
of their artistry. It should be able to define exactly the
effect of the interaction of venue and artist and enable
us to distinguish between the two. It must draw the listener
into a world where all thought of equipment is lost, leaving
us in awe of and emotionally connected to the spontaneously
arising event. We believe that the Granada uniquely masters
Field Coil Drivers
Feastrex field coil drivers represent the pinnacle of speaker
driver design. Their use of the world's finest handmade
washi paper cones, lambskin leather surrounds, and a variety
of extremely powerful electro-magnets, are legendary. Our
intent in creating the Granada Loudspeaker is to take advantage
of their greatest strengths and to augment those strengths
so that a new previously unheard level of performance can
We have chosen an open baffle design. Why? Simply, wiith
no "box" to contend with, there are no "box colorations".
The speaker drivers breathe naturally and present their
pristine innate qualities. No box means bass that is clear
and powerful and much less susceptible to room excitations.
Our baffle is machined from a three inch slab of Finnish
Birch plywood, not mdf which will deaden the sound. Since
the Granada is a bespoke product, we can build your pair
with any veneer, laminate or finish that will best suit
your taste. The Granada represents the pinnacle of 'Made
in America' craftsmanship.
mate a driver designed for full range performance with woofers?
The Feastrex field coil drivers are a force to contend with.
On their own, in a modest cabinet they will provide extraordinary
performance. Why then introduce more complexity to a loudspeaker
driver designed for solo use?
in loudspeaker design, there is no free lunch: The box used
to enhance the bass of a single driver, must necessarily
add colorations even if benign, and a single 5" driver with
limited cone excursion can only produce so much bass. When
massively driven by an uncompressed bass signal or orchestral
crescendo, a single driver can only do so much before it
will begin to distort or bottom out. This is in the nature
of the 'beast' and comes with the territory. A confirmed
single driver user will tell you that the compromise is
worth it. There is much to be said for this approach. On
the other hand, there is a benefit to be derived by relieving
the main driver of low bass duty. Now the 5" driver
can operate freely with less distortion within the very
broad range that is its comfort zone. In the case of the
Granada we wanted to offer a speaker without limitations,
or as close as humanly possible. In order to produce adequate
bass in an open baffle, high excursion woofers are required.
The woofers employed feature massive under-hung motors with
a full copper sleeve on the pole. This insures extreme linearity
and extremely low distortion. Each driver features dual
8 ohm voice coils with a high Q and low Fs for maximum power
Granada is an actively bi-amplified loudspeaker. Thus a
crossover of some type is required. Preserving the purity
of the Feastrex drivers was our top priority. As such, no
reactive components could be permitted between the amplifier
and the loudspeaker. Passive crossovers were ruled out,
and analog or digital active crossovers were the remaining
choices. Of the two, the option that affords the greatest
precision and flexibility is the digital option. With the
digital option, we are able to perfectly match drivers for
maximum imaging capabilities, properly smooth the power
and frequency response and tune the loudspeaker to each
individual room that it will be placed in. For those fearful
that a digital crossover will somehow compromise the purity
of their analog signal, we invite you to listen for yourself.
The Granada's digital crossover processes acoustic information
at 48 bits in real time, and is utterly transparent. We
feel that the advantages of a state of the art digital crossover,
when properly and subtlely implemented far outweigh any
advantages that an analog circuit may provide. The Granada
Loudspeaker couples the lastest, most up to date technology
with museum quality workmanship from Japan's finest mastercraftsmen
to create a new concept in loudspeaker design that will
take your breath away.
