Hi ,just recieved a pair of jbl speakers that I can't identify. I can't find the model number anywhere.It's a 2 way speaker system. The woofer Serial#127a,next to it, is a stamped #737 ,and the tweeter serial # is 033,next to it also is the stamped # 737. I can't see any #'s on the crossover. The dimensions of the cabinet are, H-23",W-15",L-11". The inside is well insulated. The cable connections in the back are a locking type.where you insert the cable and turn the knob to the right to lock,left to release. I know it's very little information to go on but it's all I have at this time. I'll try and post some pictures. Any information well be greatly appreciated. Thanks
