agree that 90% of the subs on the market are garbage. The interesting
thing is that this is the one area in audio where you really can do a
better job with DIY than you can buy at any price!

DIY a sub? Most are active, often with feedback. Occasionaly with digital
amps, motion sensors, set up software, room response algorythims..........

Given a big enough cabinet I could generate bass in (almost) any room.
Getting a quart out of a pint pot.....that is not something even the most
"throw money at it" R&D of B&W etc. has been able to do.

I hates dem,..... nasty, fat, subses...... (with appologies to Gollum)

Hi guys - Can't agree about subs - even when supposedly "properly set up"
Maybe I'm just sensitive to the mush which they put out but they strike me
as this years "graphic equaliser" and the sooner they fall out of fashion
again, the better.

Properly done, they most certainly do not put out 'mush', but I'll
agree that 90% of the subs on the market are garbage. The interesting
thing is that this is the one area in audio where you really can do a
better job with DIY than you can buy at any price!

Apropos of which, thanks for recommending the Tempest. I've had a
discourse with the technical chaps at Adire, and between us we came to
the conclusion that one of those in my big brick cupboard, implemented
as infinite baffle (which it approaches pretty closely) will give me,
with room gain, a flat response down to about 12Hz. Of course with a
total lack of any kind of tuned ports, the phase response and hence
perceived speed will be just great. I'm currently building the
mounting panel that will replace the door. Reports will follow...

I think that the biggest problem with subs generally is that a great
deal of music is mastered without them, and the subsonic mush that may
be present is simply not noticed. Of course back in vinyl days, it was
all rolled off in mastering anyway, but now with CDs that doesn't
happen unless somebody specifically thinks about it. The result can be
either great or horrible.

DIY a sub? Most are active, often with feedback. Occasionaly with digital
amps, motion sensors, set up software, room response algorythims..........

You can buy the 'plate' amps and drivers from Wilmslow Audio, or
import them from Madisound, or get them from audioparts.co.uk, or from
design3dw3.co.uk. All it takes is a little energy, and the will to
succeed!

Given a big enough cabinet I could generate bass in (almost) any room.
Getting a quart out of a pint pot.....that is not something even the most
"throw money at it" R&D of B&W etc. has been able to do.

Actually yes, all you need is a *very* powerful amplifier - you can
buy a kilowatt jobby from Madisound, and an Adire Tumult 15" driver
from design3dW3. Like I said, all it takes is a little willpower.....

I hates dem,..... nasty, fat, subses...... (with appologies to Gollum)

Me too - that's why mine will be unobtrusive and as tight as a kettle
drum - but less resonant! :-)

Apropos of that, download the Tempest white paper to get full T/S
specs, and check out what happens when you use the 'shorted coil'
option. I make it flat to 20Hz *anechoic*, with f10 at 10-11 Hz, and a
250 watt plate amp is more than adequate to 'Xmax out' up to 30Hz
driving two of them in a loft-mounted manifold.
