We tend to overlook instances when multiple subwoofers are used.
If you remember the KLIAV show over the lst 4 years, there was this
demo of the BBC LS3/5a, some if not most of us here have listened
to that setup. Did anyone realised that the sound you listened to
was made up of the ls3/5a speakers plus 2 passive subwoofers and
a active subwoofer? No? You never?
And yet, we might find hooking up large floorstanders with just 1
subwoofer could be 'overkill'! We have been made to believe that
it's alright to hook up a subwoofer to satelites or smallish speakers.
Large speakers are different matter altogether.
The ls3/5a could also be hooked up to just 1 active subwoofer
without the purpose made bass extender(the passive subwoofer
design) the AB-1s. What I heard was reallly different with just 1
subwoofer trying to cover the range where the passive subwoofers
operate and as well as covering the subsonic region of the low Hz!
I would still prefer the bass extenders plus the active subwoofer.
The music is just so much better sounding this way!
Mutiple subwoofers hooked to systems are not new, it's being
around for quite a while now. Users cited many reasons for it.
However, none with the approach of achieving more 3D imagings,
wider and more extensive soundscape and more perceived
ambiences and improved highs and much papable vocals! This
had to be done in a different approach from the usual way of
doing things, a more scientific & analytical approach has to be
adopted to achieve notable or perceivable results. However,
these results may not be your ordinary idea of hifi sound & may not
be deemed acceptable. One comment I would dare say is if
you want your system to sound out of the ordinary and different
from those of the 'average joe' you got to spend more $$$$ or
work/tweak/whatever on your existing system! Either you pay
someone to do it for you or you do it yourself, that is if you know
