You know those 8" fullrange drivers from CPC that we have, the ones in your open baffles? I FINALLY FOUND THE TS PARAMETERS FOR THEM! 
It also has 10", 12" and 15" big brothers 
which could make impressive open baffle woofers (very high Qts)
Look under the "L200W" column:

To anyone interested, this is a pretty nice sounding driver from CPC, suited to open baffle (Qts 1.01), and is only £10. I've tried them on baffles that were too small, and the amount bass was very surprising - there was almost more bass than from my dad's old mission bookshelf speakers!
Sorry for posting an entire thread, but apparently the parameters of this driver are often requested and I hope this finally clears this up for some people

Good work Bigwill!
It does seem that CPCl are supplying a bit more data for some of the drivers that they sell now!
Yes, I thought that 8 inch driver in the polystyrene baffles sounded very good so I would recommend it for anybody wanting to try out an open baffle wih a single driver (on a small budget).
Now, I must get my pair out and try them again!

An open baffle setup with the 15" jobs as woofers and the 8" as full-rangers, perhaps with a cheap tweeter? Would this be a good time to dig out my Doobie Brothers albums on vinyl?
I might have to give this a whirl...
By the way, I've tried my odd little 5 1/4" full-rangers in both open baffles and 25l sealed boxes (both polystyrene) -they sound very different (as you'd expect) but astonishingly good! Definately worth checking out at the price!

Perhaps we sould start a society?!?
Seriously though, I'm impressed; the least box signiture I've heard for a long while from cheap enclosures. Cutting was easy: I tried a few ways, and eventually settled on one of those cheese-wire cutters that I found in a local £1 shop and modified slightly.
The only slight hitch was discovering that polystyrene glue doesn't actually stick polystyrene to polystyrene!
Think I'll try a more... comprehensive (yes, that's the word) experiment now. That OB idea above is tempting. And cheap. I can't think of a reason not to really...
Cheers

I think I'm going to try my speakers with a cheap tweeter, I have a pair of titanium dome tweeters I got from CPC which should do nicely. I think they're 89dB efficient like the fullrangers, so they should blend well if I just connect them in series with a small cap. Once I've found a cap I'll try it and report how it sounds! I have a feeling it'll sound good, and with the surprising bass of these things, and with a bit of help in the top end, they may well be an upgrade to what I have at the moment!
