ADC 404 Bookshelf Speakers

[Ed Holland]

Hi Folks,

As the title suggests, I have acquired a pair of ADC 404 Speakers. They seem to be an acoustic suspension design from about 1968 to (date unknown).

Actually I had these for a while, without knowing much about them, then mistakenly (stupidly, even) used them to test a faulty amp, which fried one of the woofers. That was a schoolboy error I will never repeat!

Well, by great, great fortune, I just found a set of replacement drivers on ebay, under $30 including shipping, so the speakers are singing again. They're fed from a pair of David Bogen DB130 mono valve amps - rather contemporary, excepting the CD player source. I have to say that these sound rather nice, and make system well suited to our study room.

Does anyone else know about these, or other ADC products - I've seen ADC 303's (a bigger brother) on ebay, and they seem well regarded?

Cheers,

Ed
