I'm starting to get that too-many-options feeling along with going a bit cross-eyed over Thiele-Small numbers, I'd better just get on with something...But a last few questions....the 8" idea sent me looking around the web and of course I came across the Crazy 8 which sounds great , and is a possible way to go , but I'm not quite sure what they mean when they say it's been "designed"...without a port to tune it I'd have thought the speaker just sees an enclosed volume of air and one box is very much like another if they are rigid and airtight and the same volume. Can `I just put the Faital Pro 8PR200 driver in a suitable box and hope for the same kind of response as a Crazy 8? Is it worth the extra over the Fane Sovereign? I'm also looking at the Beyma 8P300Fe/N , although it seems to have a rubbery surround as opposed to paper and I read somewhere that this is bad for bass clarity , any truth in that?.. same goes for the Beyma 10BR60v2 which has a 30Hz-5000KHz range if specs are to be believed and sounds like a perfect compromise of size/power/frequency range for a home cab , but things that call themselves "studio" or"monitors" often sound a bit sterile at least in the hi-fi world...but then things in small closed boxes also tend to sound "boxy" in that world so maybe I have to re-calibrate my speaker-thinking for bass guitar.
That'll do ....whatever I come up with , many thanks for all replies and input , I'll put up some pics of the finished article before too long I hope.
