yeah I never claimed Dyn was cheap.. haha I think I paid around $800 for my 3-way front stage some years back when I bought it, but every driver is sealed, so I don't have to worry about anything being behind the drivers, which makes installation in a car a dream. Especially when fiberglassing kickpods. They use silk tweeters which lends to that smoothness, as does their 6dB/octave crossover used for their separates. The XO is a bit shallow (first order) for my liking, which limits the power handling a tad, but they sound great if you're not a fan of voerly aggressive treble like you see with so many other brands. I have mine driven with an Orion 2250SX (300Wx2ch@4 firstname.lastname@example.orgVDC) and they perform splendidly, but I'm a SQ guy anyway. SPL has no appeal for me in the mobile world. I outgrew that phase in my teens.
Ideally I'd like to move to a fully active setup, but for now the passive XOs work fine, and the head unit has mic-assissted time alignment and phase correction along with auto-EQing (a mobile version of Audyssey basically) so it works well, and I have a big enough car to allow for a decent signal path length.

For home audio I'm mainly a UK/US sort of guy, leaning toward KEF Reference and MartinLogan for my tastes.
