DB Dynamics Polaris 5.1 Speaker
Package
Overview
DB Dynamics are an Australian-owned
company and a speaker brand that we have stocked for a number of years. They
have consistently produced competent, entry-level speakers that provide
fantastic ‘bang for the buck’. However, their new Polaris 5.1 speaker package
demonstrates just how serious DB Dynamics are in terms of running with the big
boys.

This is a big speaker package. The
front floorstanding speakers are a three way design standing 1150mm tall, 260mm
wide and 330mm deep. They incorporate a silk dome tweeter, a 4” moulded silk
dome midrange and three 8” polypropylene bass drivers. They are 8 ohm rated and
rear ported, with a power handling of 250 Watts, and weigh 32kg each. Frequency
response is a claimed 40-20k Hz.
The centre speaker is a little less
intimidating but still large: 540mm wide, 200mm high and 230mm deep. It uses the
same silk dome tweeter as the floorstanders and twin 6.5” bass drivers. Power
handling is up to 120 Watts. Weight is 10.5kg, it has dual rear ports and
frequency response is a claimed 60-20k Hz.
The surround/rear speakers are a
dipole design (DB Dynamics use dipoles in several of their speaker packages) and
utilise the same 6.5” midrange drivers and silk dome
tweeter
as the centre speaker. They weigh 8kg each and measure 330mm wide, 310mm high
and 310mm deep. Power rating and frequency response are also the same as the
centre, and they are front ported.
The subwoofer consists of a 200 Watt
A/B class amplifier partnered with a single forward firing 12” bass driver. On
the front of the unit is an LCD display showing frequency cut-off and volume
level. Three large ports can be found on the rear of the subwoofer, and
connections extend to line level inputs and speaker level input/output. There is
also a rocker switch to adjust phase (0 or 180o). Frequency response
is rated at 40-150 Hz. A remote control comes supplied allowing power, volume
and frequency cut-off adjustment. Dimensions: 540mm high, 400mm wide and 420mm
deep. Weight: 31kg
All speakers are magnetically
shielded and are finished in a black ash veneer.
Besides its size, the other thing
you notice about the Polaris pack is its bullet-proof build quality. The
enclosures are made from surprisingly thick MDF (exact cabinet details were not
available at time of writing) and are well braced. The build quality of these
speakers is a big step up in comparison to previous DB Dynamics products, and is
comparable to B&W and Paradigm.
For this review the
Polaris speaker pack was placed in a room measuring approximately 4m x 6m, with
2.7m ceilings. The subwoofer was placed in the front left corner of the room,
approximately 40cm out from each wall. Surround speakers were placed on 900mm
stands approximately 1.5m behind and to the side of the listener. They were not
toed in.
Performance:
First up, these speakers need some
room to perform their best. A room of at least 4m x 4m is needed to accommodate
the Polaris package. If your listening area is smaller than this, but is part of
a larger open-living area, this package will still be suitable.
For stereo music performance the
Polaris floorstanding speakers give a forward and punchy performance. A wide
selection of music was used for this review, including Joss Stone, U2, Keith
Urban, Billy Joel, Martina McBride, Justin Timberlake, James Blunt, Live, Missy
Elliot, Billie Holiday and Fleetwood Mac. The Polaris floorstanders are not as
laid back as Paradigm’s Phantom floorstander, instead exhibiting a more
prominent midrange kick, especially with contemporary and classic rock, as well
as pop-chart music and hip-hop. If this is the type of music you listen to you
will be very impressed by these Polaris floorstanders.

Crank the volume up and the midrange
stays forceful and clear, thanks in part maybe to the silk dome midrange, which
is a design very rarely seen in speaker manufacturing these days. High frequency
performance is better than expected at this price point, and while the bass
delivery is tight, I was expecting a bit more depth considering the size of the
cabinet and the number of bass drivers. Turning the Polaris subwoofer on will
fix this, and the bass it produces is surprisingly tight and unobtrusive for
music, considering the size of the driver and the three large ports at the rear
of the unit (that in most cases will fire straight back into the wall).
While we are impressed by the
musical performance of the Polaris speakers, the presentation they provide with
movies is way beyond what we expected. One word folks: awesome! This level of
performance is basically achieved through multiple, large speaker drivers
moving a lot of air within well-constructed speaker cabinets. The amount of
sound that this speaker package is capable of pushing towards you is phenomenal.
It makes watching a well recorded action movie like Master and Commander
or Mr and Mrs Smith not just a visual/aural experience, but a
physically moving one as well. Skip to Chapter 18 (around the 55:00 minute
mark) on Terminator 3 to see what I mean.
But it’s not all noise and fireworks
with the Polaris speaker package. It also relays the quieter moments of a movie
soundtrack very effectively. The tonal match between the speakers is spot-on,
and the centre channel provides clear vocals and decent depth to male voices and
effects-heavy movie scenes. The Polaris surrounds integrate well into the system
and their dipole design provides a seamless panning of sound behind the listener
when the movie calls for it. Their placement in the room is not as critical as a
forward-firing speaker so you can still enjoy fine surround sound performance if
you have to compromise in positioning.

One reservation prior to auditioning
the Polaris speaker pack was that the front floorstanders would drown out the
considerably smaller centre speaker, but we are glad to report this is not the
case. All we had to do was turn up the centre speaker +2dB through the A/V
receiver to balance speaker volume levels.
The icing on the cake is the Polaris
subwoofer. While it is a decent performer with music, where it really excels is
movie soundtracks. It will play low and loud and has a hell of a kick. Want to
shake the pictures off the wall? No problem. Just crank this baby up and enjoy!
It is conservatively rated at a lower frequency response of 40Hz, and although I
had no way of measuring it at the time, I’m confident this sub will gladly crank
out bass as low as 25Hz at a decent volume level. The supplied remote control is
also handy, allowing you to adjust volume and frequency cut-off without leaving
your seat.
Last Words
As clichéd as it may sound, we
believe the Polaris package is a standout speaker system. If you have the space
for this system you would be hard pressed to find a rival speaker package for
less than $3,500 that offers the Polaris’ combination large-scale dynamics for
movies and competence with stereo music. No, they are not going to worry
Paradigm Studio Reference Series speakers in terms of clarity or high end
detail, but they provide a performance that the vast majority of people would be
more than happy with. Highly, highly recommended.
