Greg blew out his old girly Paradigm woofer when he got drunk one day and set his Yamaha to Pure Direct at full blast volume.
Poor little speaker. We all felt so badly for her.
See, in Pure Direct, even the low frequency like 20 - 40 Hz is sent FULL BLAST to the speaker instead of the separate dedicated LFE/Subwoofer.
So unless you have a full range speaker, don't set your speakers to Pure Direct and Turn UP the volume.
