BOSTON
ACOUSTICS ASW250 SUBWOOFER
Home cinema fans looking to augment or improve the level of
bass coming from their current home theatre set-up will do well to prowl the five floors of the coming KL
International AV Show 2013. Subwoofers
aplenty will be on offer and you might specifically want to give Boston Acoustics' mid-sized wonder, the ASW250
a serious going over.
Part of the current Boston Acoustics A Series the ASW250
is an active bass plumber featuring a
downward firing 10" ceramic glass fibre woofer in an enclosure measuring 372 x 357 x 415mm. It is also fairly heavy, weighing in at about
15kg. Retail price is RM1,750.00
Providing the drive is a built-in 100 watts RMS power
amplifier that Boston Acoustics claim is able to take low bass reproduction
capability of the ASW250 down to 35hertz.
Pundits should note that Boston Acoustics also offer
another 10" active sub in the A Series inventory - the higher end ASW650 which
retails for RM2,250. The
difference? Apart from a similar looking
and similarly sized enclosure the ASW650 comes with a much more potent 300
watts RMS power amplifier but unlike the ASW250 features a forward
firing driver. Possibly because of its
more powerful built-in amplifier Boston Acoustics is able to claim a more
extended bass response of down to 28 hertz for the ASW650 .
My personal thoughts is that there will undoubtedly be
some cause for confusion and hesitation
among purchasers especially when it involves a RM500 difference.
The ASW650 would have been better served had it offered a
similar quality 12" woofer instead of the 10" it comes with. At least
the difference between it and the ASW250 would have been that much more
palpable and distinct !
In use the ASW250 is
simple enough to set up.
Connections at the rear is rudimentary for a sub but adequate. In addition to a power on/off switch and the controls for volume, crossover frequencies
and phase, a trio of phono type sockets
allows connection from an AV receiver /processor . One of the inputs is marked LFE which when
used disables the crossover network in
the ASW250. Crossover frequency
selection in this case is achieved in the AVR/processor.
One of the greatest effects on bass performance is placement , so be sure to
experiment to achieve the optimum bass slam, control and extension. Optimum performance of the ASW250 in my system is at the
inner side of my main left speaker approximately a foot from the rear wall and
2½ feet from the side. Room
dimensions are 13' x 25'.
At this position the ASW250 delivered a well controlled and
tight bass slam. It was able to deliver
not only a good perceived bass extension but was able to go fairly loud though not quite as near the prodigious
level that my reference SVS is capable of.
That's understandable for the SVS
PB12 Plus is an entirely different animal. It is simply bigger and better and
yes, it also cost much more.
The Boston Acoustics ASW250 is targeted at a slightly
different market sector where decent performance is pre requisite of a given cost.
In this respect, in AV
systems of entre and mid level cost the ASW250
performed admirably.
The more costly ASW650 may, at least on paper, offer
certain performance advantages but its price may be a mitigating factor. My recommendation would be to opt for two
ASW250. It will of course jack up the
final cost but the advantage of improved volume, a flexible and more accurate bass loading and
extension would be significant and worth the extra cash outlay.
Boston Acoustics products will be on display/demo at the coming KL
International AV Show 2013, July 05-07, JW Marriott Hotel, Kuala Lumpur.
