We finally have a victor in the consumer electronics industry’s long-running race to the bottom: the Dayton B652. How much less expensive can a two-way speaker get than $34.50 per pair? That’s the price Parts Express currently demands for the B652.

While on a swing through Vancouver this week to check out the vintage audio scene, I stopped by to say hi to the guys at Vancouver Audio Speaker Clinic, an old-school speaker repair shop of the type I haven’t seen since I was a kid in the 1970s trying to resurrect the shredded speakers from my

I would never do what SVS did with its new subwoofer, the SB13-Plus.

We seem to be going through a mini-renaissance in the hallowed tradition of the American hi-fi show, what with this year's burgeoning crop of existing shows and welcome upstarts.
