Need info on older M&K MX-90 sub...

Hey guys........

I recently picked up a used M&K MX-90 sub to add to my Rava to get a little more"thump".
Really happy with the combo so far,but cant find much info on this sub.It's a push/pull 12in
with a 125w amp.I emailed M&K ,but so far recieved no reply.Does anybody have any info on this sub?Also,it sounds very good and goes pretty deep and loud,but kinda confused as 125 watts just doesnt seem like near enough for how it performs.Does the push/pull design have something to do with it??

Thanks for any help

Those two drivers in the M&K are just more efficient to what you're used to. If the power was boosted to 250 watts the sub would only go 3 dB louder (barely audible). These obviously don't need that extra power cause they're more efficient.
