T27 tweeters are being adopted in the world famous BBC designed LS3/5A broadcast monitor.
Model 101 combined the T27 tweeter with the SP1057 version of the B110 in a 6.7 litre closed box. The system was fully overload protected by the S-Stop system, included mechanical decoupling of the bass driver to minimize colouration and each pair were acoustically matched to within 0.5dB. The result was a system with accurate tonal balance and detailed stereo imaging - being suitable for use with the best electronics - and able to fit unobtrusively into the listening room.
