As for build quality, there is more to it than just a
pretty
cabinet.
Agreed, there is the quality of the drivers too. If you aspire to something like
the Response D100 (i.e. a driver good enough to make Proac's flagship design) then check out ATC SCM 19 or 20. The dome midrange is grafted onto a 6 inch woofer in this low cost version to make what is possibly the world's largest 6 inch driver motor of all time - see this desciption - insane as this may sound the drive motor is actually adapted from what is used on the 3" dome version in the Proacs (if this is possibly the world's largest 6 inch woofer motor then it is certainly the world's largest 3 inch motor, as used in D100). Since the SCM20 has been around for ages and ages and is still made - you can find second hand ones reasonably priced. The entire thing is British built (apart from the tweeter) - sorry to go on so much about quality but it seems that is what you cherish and I thought you would be interested. If not then sorry for wasting your time.
