well got me a Panasonic CT-990.. quite a rare item.. and decided to up the look and sound.. so bought a beater Panasonic DT-690.. took the speakers out of the CT-990 and planted them in the DT-690 speaker boxes.. sounds great.. a little more to the highs.. (piezo tweeter) but the look is much better.. speaker boxes are 100% compatible.. no physical damage done.. fit like a glove.. let me know what you think..
