Listening
Impressions: Movies
I auditioned the AS 120 with a combination of newer DVDs as well as some
older standbys with challenging bass. In Apollo 13, the launch scenes of
the Saturn V rocket thundered with clear, unmuddied impact. Next was Black
Hawk Down, which features a number of slow motion scenes with low-frequency
sounds of helicopter blades. While this review did not include instrument
measuring of frequency response, there was noticeable roll-off with material
that extended to the lowest frequencies. In particular, scene #4 "Irene"
includes material that reaches to 18 Hz as the choppers leave the staging
area and enter the city. The AS 120 did not reproduce these truly infrasonic
notes, but otherwise handled the scene well with pulsating thumps which were
modulated with clarity.
War of the Worlds, which received an Oscar nomination for sound editing,
features a lot of low-frequency material, from explosions, to the structural
groans of buildings being torn apart. I was particularly impressed with the
AS 120's reproduction of the sound the alien tripods make. If you've seen
the movie, you'll probably remember the sound to which I'm referring, but the best way
to describe it is a wailing foghorn which decreases in frequency rather than
being a single fundamental note. It's mastered at a fairly high level, no
doubt to startle and instill just a little fear in the listener, and the AS
120 did just that with force and accuracy.
No subwoofer review is complete without a submarine movie, my personal
favorite being Das Boot – The Director's Cut. Though both the video and
audio production quality are of 1980s vintage, to me this epic movie is
still second to none in the genre. The output of the Canton subwoofer was
never an issue, providing powerful bass throughout every depth charge-laden
scene. Even when pushed to aggressive/loud playback levels, the AS 120
retained decent dynamics, but I noticed a moderate increase in distortion on
the most demanding passages.
Listening Impressions: Music
So the AS 120 can produce low frequencies with some authority, but how'd it
do with music material? Well I started with a CD that demands quite a bit of
subwoofers, David Gray's White Ladder. Most of the tracks are a mix of male
vocals, acoustic guitar, piano, drums, and very deep bass. From "Please
Forgive Me" onward, there are a number of synthesized bass lines that go well
down into the 20-30+ Hz range. I have listened to this disc with other
subwoofers, and have been unfortunate to hear the dreaded "Clack" of the
driver bottoming out as it reaches maximum excursion attempting to reproduce
the lowest frequency notes. But, the Canton sub handled each of these tracks with
aplomb.
Next up were some piano tracks, for which I chose a disc with piano concertos
by Schumann and Dvorak. The multi-channel hybrid SACD (Channel Classics
CCS-SA-17802) features pianist Paulo Giacometti with the Arnhem Philharmonic
Orchestra conducted by Michel Tilkin, though I listened to it in two-channel SACD mode. The lowest octave and a half of the piano (all below 80 Hz) and
the deep orchestral instruments sounded natural and managed to blend nicely
with the high frequency material.
Conclusions
The AS 120 SC acquitted itself well for this review. It is attractively
designed, with very good build quality and fit and finish. It may not reach
to the deepest depths with perfectly flat frequency response, but it
certainly does not have an audible "hole" at the low end that I've
experienced listening to some other subwoofers. I found placement to be a
bit trickier than other subwoofers I have used, but this will largely be
dependent on the characteristics of a given listening space, and the AS 120
offers users some welcome flexibility here with the room correction circuit.
The ICEpower™ amp and Canton driver took everything
that tough movie and
music tracks could throw at them and provided enjoyable accuracy.
The market for subwoofers at or near the $1,000 mark is an extremely
competitive one. Powerful amplification, sophisticated equalization
capabilities, and even 15" drivers are available at this price point. Also, many companies sell to consumers
Internet direct, which keeps overhead costs
to a minimum. Conversely, Canton sells its products through a network of
dealers and installers which adds overhead to the retail cost. So while the
AS 120 may not represent the best performance/ value ratio in this price
segment, it does offer good performance for its size, it has very high
aesthetic appeal and great build quality, so I would not hesitate
recommending an audition to prospective buyers.
