With the amp on one side of the room, is it ok for the speaker cable runs to the two speakers to be of unequal lengths? I thought not, but my recent professional cable installation was done with 3 metres of cable for one speaker and 15 for the other. Decent quality 4mm square section copper cable. Are the unequal lengths a factor?
Should the woofer and tweeter screws be tightened to specific torques? Are there any torque specifications available somewhere?
