Summary Comments |
Part I: General Information/Features |
|
|
Packaging Solution |
4.75 |
Package is very protective of the
subwoofer, and should withstand rough handling during shipment. |
Owner's Manual |
4.50 |
Well written and comprehensive, with good
diagrams and instructions on using the PEQ. More information regarding
the amp standby/on/overload light would be appreciated. |
Size/Weight |
3.75 |
This is a fairly large and heavy
subwoofer, but with a manageable footprint. |
Floor Interface Solution |
4.50 |
Spiked brass feet with discs, or optional
soft rubber stick-on feet, or the option of no feet at all.
Installation of spikes and discs requires two people and can be tricky
with a subwoofer this heavy. Be careful not to drag the spiked feet
over a carpeted surface or they might tear out and damage the enclosure. |
Aesthetics |
5.00 |
Typical of Rocket products, the UFW-12 is
stunning from all angles. |
Fit/Finish |
5.00 |
The piano gloss end caps are deep and
lustrous, the wood is excellent in grain and smoothness and there are no
flaws anywhere in the finish. The amp and woofer were well fitted and
all screws were properly torqued and seated. |
Available Finishes |
5.00 |
Stunning and exotic real wood veneer
finish options to fit anyone's tastes and décor: South American
Rosewood, Piano Gloss Black, Piano Rosewood, African Macassar Ebony,
Gloss Bird's Eye Maple. |

The UFW-12 represents a good performance
value at the $1,000 price point. |
The UFW-12 is a handsome and beautifully-finished subwoofer with excellent
build quality and several unique finish options. I liked the flexible floor
interface options, which include classy spiked brass feet and discs. And
while the UFW-12 will never disappear into a room, its striking good looks
give it a high spousal acceptance factor for its size.
The efficient Glass G amp is powerful and has useful features like an
electronic limiter and steep high-pass filter to help protect the woofer
from overload, a single band PEQ control for taming an in-room response
peak, and slick three-color operating light showing standby, normal operation,
and clipping/overload.
The R-DES external PEQ system with PC interface is an innovative and easy to
use product which adds an extra dimension of equalization capability not
found on any subwoofer in this price range. The five PEQ bands can tackle
the worst of room modes, and the four onboard memory settings allow for
custom movie and music EQ curves. In addition, the product is well supported
with on-line help and tutorials, revision downloads, and the innovative Onix
Graph Paper for plotting the in-room FR.
On HT applications in a mid-size room, the UFW-12 exhibits respectable
mid-upper bass dynamics and good extension to about 25 Hz. At higher
playback volumes, the UFW-12 limiter will occasionally compress deep bass
passages, so hard-core HT enthusiasts might consider dual UFW-12 for an
additional 6 dB of headroom.
With popular music, I found the UFW-12 to exhibit impressive balance,
coherence and articulation. Pitch is well-preserved at/above 35 Hz, and the
UFW-12 renders low E beautifully. With the help of R-DES, integration with
the mains is smooth and seamless.
AV123 has hit the mark; the UFW-12 is a well-balanced
and attractive subwoofer which offers solid value at the $1,000 price point.
