well, in terms of price the SVS closest to this one is the PB12NSD.
honestly, the MFW with its 15" should be better than the PB12NSD.
but right now with their backlog and "not as good as SVS" customer service, i'd choose the PB12NSD... oh right, I did.
i hate the fact that "I have the money" "I want to buy your sub" is met with "its not available indefinitely and then some" if the MFW were available right here right now, i'd have ordered one already.
with regards to a 600 dollar axiom sub. don't. they couldn't do it with 1200 dollars, they can't do it with 600 dollars.
on a side note ... everyone seems to sing the MFW's praises and yet there are only a handful who actually has one. "things that make you go hmmm" i suggest you take them with a grain of salt lest you be immersed in too much hype.
if i had 1600 bucks right now and no other sub... i'd get the PB13 hands down, case closed, nuff said.
