Technics SB-T300 is an 8-ohm speaker system with an allowed input of 100W (DIN). It features bi-wiring connection for superior sound reproduction, and the speakers are designed to be anti-magnetic to prevent discoloration on TVs. The speakers should be placed away from walls and windows to prevent resonance and feedback, and they should not be placed on the same surface as a turntable to avoid acoustic feedback. The instruction manual emphasizes the importance of using speaker cables with the correct polarity and avoiding excessive input to prevent damage to the circuits or other malfunctions.
