I can't remember exactly what the measurements were, but right around 8" or 9" per side. Pretty small box. Got the specs off the PartsExpress web page.
Right now I'm using an old Technics SA-810 receiver, but if I push the speakers a little hard, the amp, for some reason, will heat up and shut down. At low listening levels, it will play all day, but that takes a lot of the fun out of it!!
Yeah, yeah, I know............my speakers blow. Bose 301, yamaha cheapo 3 ways, and JBL CF-120's. I really need to make a serious change with these things.
