I fear that with the introduction of hard science and engineering, including advanced measurement techniques, into speaker design around 50 years ago the standards that the commercial manufacturers could reach became hard to replicate on a DIY basis. However some very good designs have been released onto the market over the years in kit form for self-builders. And now that high quality sound cards and calibrated reference mics have become readily available DIY design, based on manufacturers' Thiele Small parameters, is again possible for the amateur.

If you check Troels Gravesen's pages here http://www.troelsgravesen.dk/Diy_Lou...r_Projects.htm for example, there is clearly a lot going on. I'm about to start building a pair of Dennis Murphy's CAOW1s http://murphyblaster.com/content.php?f=CAOW1.html. I've heard a couple of other pairs and for smallish standmounts they sound very impressive indeed ! Instead of using plywood for the cabinets, however, I'm going to follow a friend's example and make them from Corian. So there is still experimentation out there.

Cheers,

GJ
