i think they are factory matched at the plant in russia...taylor, i believe, simply re-tests the frequency response...but i could be wrong. i highly doubt you'd be able to match them yourself. did you buy them from the sound room, and did you ask for the matched pair?
finally, you could call or email taylor and ask him yourself, i've talked to him and dealt with him and i think he's a real nice guy and raelly caters to his customers.
