I have a pair of 1977 decorators that have been modded with the Crites crossover and tweeter. I also put a brace across the motor board, side walls are braced to each other as well as the front/rear baffles and corners. Also added braces between the top/bottom of the port. Mid horn was damped with spray and wrapped with felt - no ringing.
I love them. Capable of such delicate, subtle tone and yet can really get "obnoxious" when cranked. Driving them with a 30watt push pull EL34 amp.
Room is not large 11X18, and I have them set up as per the Cardas speaker configuration. If the IV's are better than this, I would happily get a pair (however, budget does not allow for that)
The CW's and ESL-57's are my main speakers. Very different, which I like, and both are satisfying in their own way.
They certainly occupy some "real estate" in the room, but well worth it :)
