yeah, got some TAD 1601B drivers and this is a problem... look at the difference between the altec gasket on the left and the TAD on the right...
so it looks like i've got 6 or 7 mm increase in gasket thickness - and that's before i've allowed for any difference in cone excursion between the TADs and the Altecs.
I can look at the cone excursion specs but that won't tell me about the speaker surround movement, which is the bit which may touch the baffle - any thoughts on this, or will it be ok?
the TADs sound amazing at low levels though, but when you turn them up the surround definitely touches the baffle board...
thanks
