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

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]
The trade of between 1 large sub and 2 smaller subs (all other things - including overall price tag - being equal) is that 2 smaller subs will allow placement that smooths bass response while the single sub (again properly chosen at the same price point) will allow greater clean output. Effects tracks WILL challenge your subs output capability, music usuallly does not.

Therefore, while there's a benefit to maximizing BOTH output capablity and smooth response, at any given price point (shy of zillions) you must choose one (to at least some extent) or the other. My rule of thumb is smooth (2 subs) for music and loud and clean (1 big sub) for movies.

Hope that clarifies MY thought process. As always, YMMV>

Good Luck

Also if you buy used,listen to real deep sounds only while checking it out.This may reveal a damaged voice coil from over driving.It will sound like something rattling or jingling inside it.You may have to put your ear close to it.It should take only a few minutes to hear this.
