I've had an idea for awhile to buy a set of cheapo speakers and try to make something good around the base carcass. So, I got me a pair of Eltax Millenium floorstanders for £75 which are nice looking boxes apart from the tacky silver cones. So, where would I start looking for quality drivers etc.? Are there standard woofers/ tweeters that speaker companies use or do they make their own? Are there any good web resources for DIY speakers. I don't really have time to build them from bits of MDF but would like to try moddifying an existing carcass.
