BUT much safer than using phone plugs! No chance of accidental disconnect, dont suffer from the shorting out your amp problem when disconnecting at the speaker side, cant accidentally plug them into something you're not supposed to (well, extremely small chance anyway), bi/quad amping capability, more durable, easier to fix than a phone plug (no soldering), much tidier with heavier gauge wires, no chance of mixing up a speaker cable and an instrument cable... And miles better than using *shudder* XLRs for speaker connectors... Silly Bose!
