So what 'turn of phrase' were you meaning?

he didn't mean it was an urban legend (cos its real 
). More like the legendary underfloor hornloaded sub. Its somewhere in the link:
here's its half completed form:
That's not sane.

Looks perfectly sane to me.
Could grow spuds in it aswell, maybe some carrots!!

No, just suitable cables

Its a G thing
Certainly seems to be the current trend. For their size they are really incredible. Foo Fighters at Earls Court I couldnt believe they could project such a visceral sound at such high SPLs.Onno said:

Hi,
Goodies, the 1960's EV 30W (the 30 refering to the diameter imperial style) and the current Fostex FW-800 (metric) at least as big, if not bigger (scale's kinda hard to judge well without context.
BTW, here the hint to all those who pooo-pooo large drive units, it seems you like slow bass, as FAST bass REQUIRES large cone areas (if it is not immedialy obvious why, study a little physics, dare I say mass, spring, motor strength and surface?).
Some of the fastest bass I ever came across came from hornloaded Precision Devices 24" drivers, it probably was the loudest too, per driver.
And no, lack of low bass and heavily distorted upper bass is not "fast" bass, it is merely "no bass but loads of distortion", if you like it, enjoy.
Ciao T
PS, given the mention of the BT7, if you use them with a suitable upper bass system and can run them so the mechanical noises from the drive system are drowned out they are great, we used them in the latter of my PA Days, with Community RS-880 tops and community 4 X 10" fillin's (to get some speed), plenty of low SPL for a small package

I've seen those PD drivers. Love the industrial cast octagonal edges and outrageously impressive polished magnets. If I had the room I'd love a coffee table / sub made with one of those 24's. Trouble is it would hardly be turned on, so as not to overwhelm the rest of the music. One day :MILD:

Hi,
I did.
Violently so.
About T-80 violence level.
Anyway, the only people arguing against VERY LARGE woofers are either serely underendowed in the trouser dept, or have never experienced them and are therefore strictly speaking from expressing opinions.
In my experience an 8" diameter diphragm driven by an 8" voicecoil (eat dat dynaudio) makes a nice midrange driver.
A 5" 'bass' driver? You have gotta be kidding gov.
Ciao T
PS, if in doubt, remember, the average kick drum is 24" in diameter and the skin gets displaced, depending on force applied via pedal and the tightness, both which contribute to the sound, by between a quarterinch to an in inch. I will leave it to the mathematcians in the crowd to wrok how many feet a 5" diameter diphragm has to be diplaced to match a 24" diaphragm displaced 1/3rd off center by 1".
