when I say something your best bet is to listen..I design speakers FYI..
note the compliance to mass ratio of the tc designs
they just don't have the mechanical dampening to be used in what we normally use for ported alignments, don't believe me see how peaky and how much GD you get with a lms-r 15 is 4 tuned to 35..
I'm not using modeling software I'm telling you physical facts..
the PMs needs 2.5 tuned to 28..
there created to provide a flat wide bandwidth with low group delay aka good sounding drivers..
they are amoung some of the best when optimized and no they aren't loud..
in fact the lms sound alot like the IMAX but with more balls..
as far as the 9500 not competing with the xl that's just a good laugh..
