After reading Clement
Perry's review of the
Nova Bravo loudspeakers,
I became very interested
in giving them a listen.
When the opportunity
arose, I eagerly agreed
to do this follow-up
review.
For a number of years
now, loudspeaker
designers have been
trying to find ways to
get a larger, fuller
sound from smaller
enclosures. It is
surprising the degree to
which this goal has been
achieved. The Nova Bravo
is just such a
loudspeaker. The Bravo
stands less than four
feet high and is less
than ten inches square.
The pair that I had was
finished in a light oak,
to a high degree of fit
and finish. In my
opinion, they are a very
attractive pair of
speakers that should
easily fit into most any
décor.
Given the relatively
small size of these
speakers, they have a
surprisingly full
low-end response.
Product literature
attributes this response
in part to the carbon
fiber filled composite
bass-midrange driver
derivative of the much
larger Evolution
speaker. The result is a
driver that is very
stiff while at the same
time low in mass. The
major contributor to
this response is that
the cabinet is a slotted
or a reflex design.
Briefly, with a reflex
or bass reflex design,
the cabinet vents some
of the low frequency
energy into the room
through a port, or slot
in this case. The port
is lined with absorbent
material in order to
smooth the frequency
response. In this case,
the port is located on
the rear of the cabinet.
The trick here is to
delay the energy leaving
the port long enough to
be in phase with the
energy being emitted
from the front of the
woofer. Admittedly this
is an
oversimplification, but
this method will
generally result in a
much deeper bass
response when compared
to a sealed box design.
As you shall see, Nova
has utilized this design
to produce a rather
small package that
produces a large sound.
The Sound
I set the
Bravos up in my usual
listening position. They
were just about seven
feet apart and three
feet out from the rear
wall. My seating
position formed the last
leg of the triangle at
just about seven feet
away. I gave them a
slight toe in; this
seemed to provide the
best image. Neither too
defuse nor overly
etched.
One of my favorite CDs
is Patricia Barber's
Companion, [Blue
Note/Premonition 7243 5
22963 2 3], recorded
live at The Green Mill.
Cut two, "Use Me,"
begins with a tight solo
bass line that is a good
test for a speaker's
upper to mid bass
performance. While the
Bravos performed well
with tight and tuneful
bass, the output level
seemed to diminish as
the bassist explored the
lowest levels of the
instrument, but Ms.
Barber's voice was
conveyed with what I
felt to be the right
amount of intimacy and
breathy detail.
The venerable Kind of
Blue, by Miles Davis
[Columbia Legacy CK
64935], came across
quite well overall.
Tonal shadings were
resolved accurately but
the brass tended to
become forward and hard
sounding when the volume
was pushed past low to
normal listening levels.
This also happened with
some female voices under
the same conditions.
I found these speakers
to be somewhat cable
sensitive. With the
Audience Maestro speaker
wire, the treble was
clearer but harder
overall. I achieved the
best sonic results with
a bi-wire run of Cardas
Neutral Reference
speaker wire. With this
wire, the treble
hardness was not
entirely eliminated, but
it was greatly reduced.
This problem did become
much less noticeable at
more moderate listening
levels.
The reason for a ported
enclosure becomes
apparent with music that
has a very prominent
bass line. "Genesis,"
which is the first cut
of George Duke's album
Illusions,
[Warner Bros. 9
45755-2], is a case in
point. This is heavily
synthesized dance music
that makes very strong
demands of speaker's
low-end capabilities.
While your pants legs
won't flap in the wind
from the bass energy,
the output is more than
adequate to serve the
music. Given the fact
that we are talking
about a 7" woofer here,
the performance in this
area was quite
impressive.
Aaron Copland's Third
Symphony, [Reference
Recording RR-93CD] is a
good test because of the
full range of the
symphony orchestra. The
Novas were able to
deliver the width and
breadth of the
performance, although at
reduced scale when
compared to larger floor
standing speakers.
Strings had the proper
silkiness without any of
the nasties that often
come along with the
reproduction of those
instruments. While they
could not provide the
full musical impact of
"Appalachian Spring
Suite" that I have heard
from larger and more
expensive speakers,
given their size and
driver complement, the
Bravos acquitted
themselves quite well.
Everything taken into
account, the Nova Bravos
are a fine pair of
loudspeakers. The field
in the 4K-price range is
crowded, but the Bravos
can certainly hold their
own there. While I feel
that these speakers may
be better suited to jazz
or rock, they also will
do a credible job with
other musical fare.
Given their small
stature, they should fit
easily into most rooms.
Choose your cables and
associated equipment
carefully. I would avoid
any thing that is zippy
or hard sounding unless
you prefer that sound.
If that is your cup of
tea, you could still end
up with too much of a
good thing.
If you are in the market
for a pair of speakers
in this price range, I
recommend that you do
give the Novas a serious
audition.
