subwoofer question


hi everyone, i have a chance to buy 2 m&k mx-150thx(mark I) subs for $900 shipped.
first off is this a good deal or am i over paying.
next, because these subs are old (10-15 years), can they compete with the new subs which use better technology.
i only use my system for home theater.
my room is 14x12.
will these subs be great for my room or should i get one really great "USED" sub like a jl fathom, or velodyne dd series, svs, etc.

thanks so much

At $900 used in a manageable sized room like yours, for HT only use, I would definitely buy a more current single, large sub.

IMHO, a pair of M&K (or any other brand of) subs might make sense for a dual use system where twin subs can be used to smooth bass response without adding EQ, which some people find objectionable for a music system. For HT only, I'd use a single large unit and also make sure that I had Digital Room Correction capability (e.g. Audyssey) somewhere in the chain to achieve smooth bass response via EQ.

Just MHO.

Good Luck

thanks for all your input guys.
i see everyone is against the m&k purchase.
i am strictly home theater not 2 channel.
i do have a audio control bijou equalizer(manual up/down sliders) which smoothes out the frequencies, but doesnt do anything for phase or whatever else the microphone eq's do(audessy, ARC, etc.)

do you really only benefit in 2 channel with 2 subwoofers(left and right)?

for home theater will 1 great high end sub do just as well as 2 subs would... or atleast close to it?
I forgot besides HSU and SVS,someone just posted this the other day if it helps.LINK>>[http://www.hometheatershack.com/forums/subwoofer-tests-archived/6015-index-subwoofer-tests-manufacturer-model.html]
In your size room(14X12),one may get buy.Some have a home trial I believe.It depends on how much thunder you want.
They seem to like it.>>>[http://svsound.com/Reviews/2006-12_S&V_Review_SBS-01-PB12.pdf]
