In a search for some more bass bins, considering selling my MTH30's, as they lack the punch i am looking for. (the bass is phenominal, just not kicky enough i guess). Came across this a while ago, im sure weve all seen it. I have attempeted to put in in HornResp, but i believe i'm doing it wrong. has anyone the time to do the measurements correctly? Also has anyone heard or own these?
