Harry,
Get your hands on the best sounding .04uf caps(The caps need to be matched and as close to that exact value as they can for a 79.5Hz filter. You might want to measure the value of the X-2's you have and try to duplicate that value, it should be .04uf but all of the X-2's I have measured were way out of spec. This way is won't change the bass balance.) Get some M&F RCA's. Solder the caps on the hot side and a wire for ground. Sit back and prepare to enjoy a pair of filters that will put a grin on your face.
After word your X-2's will be for sale.
