I have a set of Fisher speakers (a very ill-advised purchase before I really knew anything) that I've long since upgraded from and have long since tried to sell, to no avail. They've been sitting for over a year now, and frankly the sight of them is starting to bum me out. Any friends looking for a music system would want something smaller, and any of them with any knowledge of speakers would prefer something a bit higher fidelity...and smaller. Would be a shame to bin them, since they're utterly pristine-not even a scratch on the fake vinyl or a dent in the cones.
As is, they sound fairly decent! A bit too midrangey and dull, but with proper EQ and they transform into something decently punchy. So if I can't sell these or even give them away, why not mod them into something better? The weak-spots are the usual cheap old speaker weak-spots: the crossover is but a resistor and a couple capacitors (6.8uF and 3.3uF caps, and a 1.5ohm resistor, IIRC?) wired between the drivers, the cabinet is empty and unbraced, and the tweeter is a cheap 3" paper cone. Very cheap, very basic. How hard would it be to wire up a slightly better crossover and add in a nice dome tweeter?
The nearest specs I could find on these are:
Model: Fisher DS177
Woofer: 12" cone, 50-70 watts, DCR=4.3 Ohms
Midrange: 5" cone, DCR=6.5 Ohms
Tweeter: 3" cone, DCR=3.0 Ohms
Power Handling: 5-75 watts (not sure if peak or continuous)
Nominal Impedance: 8 Ohms
Model Year: ca. 1981-1984?
MSRP: $99 (1981)
