I just purchased a tech soundsystem ct-212 It was advertised at a local music store as a (1)'12" cab with tweeter. The second speaker is actually out of site and loaded on an angle almost sideways in a horn type of formation. The tweeter is also mounted in the horn section. Well i took off the grill and to my amazement the speaker inside had been replaced by a Pyramid SuperPro PSC 700 watt stereo subwoofer (the actual RMS rating is 350 watts) I still have the original Tech front speaker and tweeter and only have played it at home. Sounds really good so far. Taking it out to a blues jam next tuesday. Just wonder what all the speaker experts think of this setup? Was this done by some deranged person or did he or she have something in mind?
