Krix is an
Australian speaker company that builds speakers for both the home theater
and commercial cinema markets. They're the oldest speaker company in
Australia (founded in 1974), and here in the US their consumer products are
distributed by FDW Worldwide.
Secrets has previously reviewed several of
their models, and I had the opportunity to evaluate a multi-channel system
built around Krix's new Epicentrix center channel unit.
Features & Setup
The Krix 5.1 setup included the
Phonix floor-standers for the front left/righ, Epicentrix center, KDX-M monitors for
the rear channel, and Seismix 5 subwoofer. Krix manufacturers their speakers
in-house in their own facilities in Australia.
The Epicentrix is Krix's flagship center channel and is intended to match
the Phonix or Esoterix front channels. Both the Epicentrix and Phonix
speakers are physically large units, and share the same complement of
drivers though different three-way crossover networks.
The tweeter is a 1" dual
concentric diaphragm (a.k.a. ring radiator) design from Vifa/Peerless. The
midrange unit is a 5" coated paper driver, and the bass is handled by an
array of four 5" coated paper drivers (different design from the midrange
units), all sourced from Peerless.
give you a sense of scale, the Epicentrix is three feet wide and weighs over
50 pounds. In my home theater setup, I stand- mounted the Epicentrix just
below and approximately two feet in front of my wall-mounted projection
The Epicentrix's drivers are not magnetically shielded for use
adjacent to an older CRT-type display, but the cabinet seems sufficiently
braced to place a digital display on top of the unit.
The Phonix units were
placed approximately four feet on either side of the Epicentrix and slightly toed in
to the listening area.
A pair of KDX-M bookshelf speakers were used for the rear channels. These
are a two-way MTM design featuring a pair of 5" doped paper mid-bass drivers
and a 1" fabric dome tweeter. I stand-mounted these to the sides and
slightly behind the seating area for the purpose of this review.
Bass duties were handled by the Seismix 5 powered subwoofer. The Seismix 5
is a box subwoofer design and uses a 12" paper cone driver powered by a 400
watt amplifier. This amp has ample power (capable of peak output of 800W),
and is also used in Krix's top-of-the-line 15" Seismix 7 subwoofer.
The Epicentrix and Phonix units reach a claimed low end response of 40 Hz and 30 Hz
respectively. I tested the speakers both with full-range signals and also
crossed over at 80 Hz to the subwoofer. Most of my listening was done
All of the speakers featured an Atlantic Jarrah wood veneer, with the
Phonix and Epicentrix having a black painted front baffle. This wood, native
to Australia, is a deep red in color similar to mahogany and I must admit
that the veneers were very nicely done, though the flat black front baffles
looked a bit plain by comparison.
All the speakers have removable grilles as
well. Overall, the fit and finish of these Krix speakers is excellent.
I listened to the Krix system in a
wide range of settings, including two-channel audio, multi-channel audio, and
For music listening, I mostly used the Phonix left and right channels in
conjunction with the Seismix subwoofer. The Phonix units are nearly
full-range and can be quite satisfying on their own, though a sub helps with
low bass whether listening to concertos or electronic music. I was impressed
by the precision of the imaging that they delivered, as large full-range
speakers often lack the imaging capabilities of monitors. In listening to
various Vladimir Horowitz recordings, the Phonix speakers convincingly
reproduced the grand piano in his bold style.
It took a little while to get output levels and placement just right, but
the Seismix 5 provided ample output volume across the low bass range. The
claimed frequency response reaches 16 Hz, and in watching Blade II
and other reference material I've used for subwoofers, the Seismix seemed to
deliver the goods. In conjunction with the bass output from the Epicentrix
and Phonix units, the system handled the rolling thunder of artillery in the
Dolby TrueHD soundtrack of the Letters From Iwo Jima HD-DVD with
multi-channel mode, the seamless blend and dynamic range from the front three
channels in particular comes to the fore. Again, in Letters From Iwo Jima,
there are a number of scenes with enveloping sounds coming from around the
soundstage like bombing runs or ethereal nighttime footage. There was no
audible "jumping" as these environmental sounds moved across the center
The KDX-M speakers in the rear channels had reasonable tonal match,
though they have different driver compliments than the Phonix and Epicentrix
units up front. A system with another pair of Phonix speakers in the rear
would be quite a sound to behold.
When watching the HD-DVD version of The Matrix, I was impressed by
the dialogue clarity of the Epicentrix and channel separation of the system.
In particular, in the scene where Neo and Trinity first meet in the club,
the hushed conversation could be heard perfectly despite the pulsating metal
soundtrack of Rob Zombie in the background. Overall, hearing this Dolby TrueHD soundtrack on the Krix speakers was a joy.
I was thoroughly impressed by
this Krix system. For multi-channel home theater and audio settings, the
Epicentrix is a standout center channel speaker and compliments the Phonix
mains quite well. Listening to a setup like this makes you wonder why more
speaker manufacturers don't place greater emphasis on matching the output
capability and tonal balance of all three front channels. Given the
importance of the center in multi-channel home theater, it's easy to
appreciate the Epicentrix and all its capabilities. This is especially so
now that we don't place the center channel speaker on top of TVs anymore,
and the HDTV flat panel units are getting so big.
At approximately $9,000 for the entire system (each model
available individually), these Krix speakers are not inexpensive, but offer
good aesthetics and excellent performance for the price.
