want two lol

Yep, I gotta admit it - that *is* impressive!!! :-)

Not really, as the system would have worked better as an infinite
baffle arrangement, avoiding the need for all that concrete. Nice
technobabble bull****, though.................


I trust fellow 'sportsmen' here will note that I don't take an easy
shot at this 'low bird'...... ;-)




Best easy shot is with a http://photogallery.net/sub.jpg big sub......


I've been contemplating building a sub, but not quite on this scale!!!
;-)



I remember an article in one of the UK mags some years ago, can't
remember which ... of a guy in Wales who specialised in concrete
underfloor subwoofer builds :-)


Yep, not uncommon it would seem and I was told recently that when central
heating started to become commonplace a number of 'audio buffs' converted
their chimneys into massive horn speakers...!!!???



The driver/s at the chinney pot end?


So I gather, but this was from another Scot in whom I'm fast losing
faith.....


Thats reminded me of one of my early DIY build speakers (full range) in
concrete pipes - sounded okay.
I thought I was daft building support towers etc. underfloor but now I
feel quite 'normal' after seeing that subwoofer build site :-)
