Hi Tony
Basically your enclosures should be solidly made, heavy, internally braced, internally dampened, airtight (unless ported), resonant free, isolated from the floor as much as possible. When at a reasonable volume the theory is that you should not feel vibration if you were to put your fingertips on them (more easily said than done).
Take a look at this site -

It will also help you with speaker cables - that is making your own as opposed to spending £7000 for a 4M pair of Nordost Valhalla's.
Have fun

Thanks David, useful stuff
Cables are not a concern. I have followed the debates about speaker cables for 15 years. As an engineer who has been involved in testing cables (including speaker cables and 'blind' listening tests) and subsequently as an academic who has read much published (not by manufacturers of cables!!!!!) material in this area I have concluded that there is absolutely no discernable (or measurable - even with extremely precise instruments) difference in the signal between 'exotic' oxygen free, solid silver etc., etc. cables at £1000 per meter and 'average' speaker cables at around £5 per metre. No signal change means the same sound at the speaker. I certainly could not hear any difference in the sound during the tests I was invovled in.
This subject was also exhaustible discussed for many years by the likes of John Linsley Hood (arguably one of the very best amplifier designers) in Electronics and Wireless world. The outcome of these published experiemnts and discussions concluded that the 'golden ear brigade' are seeing (hearing) the emperors new clothes.
OK. With very cheap, thin cables coated in poor quality insulation, the sound will be affected, but I am talking about 'decent' lower priced speaker cablers versus the 'exotic' cables here.
One pays the money and makes your choice - £5/m for me.
If people think they can hear a difference with £50/m cables, fair play to them - it can't be measured though and they are probably the only ones who can hear it :wink:
However, the choice of amplifier, source and speakers makes huge differences, hence my desire to get the enclosure right.
If you're interested, the amplifier driving these speakers is made by Rega (Famous for thier Planet turntables)
