I used to own a pair of TDC 1 speakers. Actually, I guess you could say it was my first entry level mid-end system and consisted of the TDC model ones, a Cambridge Audio receiver (probably no more than 10 Watts RMS into 8 Ohms; in college I tried to drive a dorm-mate's new Advent 1s and no cigar, the amp just couldn't deliver the current quickly crapped out when we pushed the volume!), along with Garrard turntable with a Shure MM cartridge, all the for the rather high system price (for a student anyway) of $199 for the whole kitten kaboodle; they included the lamp cord speaker wire too!
The TDCs were a two way, sealed (no port) enclosure and they were soft at the top end, in fact I had to run the treble at 3 O'clock just to begin to get them to tweet.
But I discovered many new bands on that system from 1973 to about 1979 when I upgraded and gave away that system to a friend.
Anyway they probably aren't worth much now but I would be curious to know what became of TDC, a local Boston area manufacturer that really tried to get locally into the nascent "high-end" market in the early 70's. Tech HiFi, a local dealer chain carried the entire TDC line. Whatever happened to Tech HiFi?
I doubt very much that TDC had anything to do with British manufacturer Tannoy.
