Was at the end of the week on nem tuningtreffen. there I participated in the db drag. Classification was according to number of subs. So started at 1 sub. Result was 141,7db with a stupid basstest cd. Actually wanted to measure with sinus tones but it must all take the test cd from the organizer. Well, the loudest in category 1 woofer was of no use. Was even a little surprised as also Mtx and emphasic 38er were there at the competition. Even 2 5500 mtx 38er were quieter. a term lab was measured with it. But I will do the measurement with a term lab in the course of the week at the dealer. Guess how much I’ll do around the 140db I’ve got a AS x-ion 12 plus that is powered with 700watts. What did you build a bass tech and how much db do your woofer. Images of the bass compartment would be great too.
