they sound much better, less boomy
i used to hear the bass coming from below the seat
now it feels like its coming from the door speakers
i like it much more
i am crossing over my door speakers at 60hz
and believe it or not they sound great
but i think the slight resonance i am hearing is the plastic cage of the actual speaker
not something else vibrating
i am using the logic 7 speakers
very happy with them otherwise, except at certain frequencies they resonate
can't think of a fix for that
i tried using weather sealant foam like you did on the 344is
improved, but not removed the resonance
any ideas?
