Swap the +/- connections on ONE speaker so they're out of phase. Face the two speakers towards each other about an inch apart and play loud, bass heavy music for as long as you (and your neighbours) can stand.
how best to break in speakers?
i am close to buying new speakers for one of my kids apartment. leaning towards wharfedale diamond 8.1's. every thing i've read warns about long break in period. what's the best/fastest way to go about this. i'd like to break 'em in before i give them to him for xmas. any thoughts suggestion? feel free to comment on speaker choice too. he'll be riving them with a nad 3140 in a 12by 10 room.
