whoom instead of BOOM

hi everyone. new into home theater(though been running loudspeakers off a tv since the early 80's). anyway, i'm having a problem with the low frequencies. at the volume at which i get the spls i want(pants rattle a bit, couch vibrates etc.) i get a whooom response and not BOOM and lose definition and clarity. is it possible to acheive these spls without the "whoom" mucking it all up?
the room: 35x25x10 it is not closed in completely
the system: mirage m5si fronts, mirage 595si rears, mirage om-c2 center, mirage bps 150i sub(also working with dialing in a polk psw12 sub together), onyo txds797 processor. the front end is a panasonic dvd-s97.
THANKS!!

My Velodyne HGS-15 is crossed at 80 Hz. It blends seamlessly with my KEF 104/2s, generates that subtle vibration you feel at a pipe organ recital when a big pipe is opened, and can make you feel pressure on your chest during explosions in certain flicks. With a 15 inch woofer, 1200 watt DC amp, and huge motor, it meets Shadorne's specifications. In my application, a 19 X 14 X 8 room, an Auralex SubDude base greatly improves the sound, removing boom and seeming to extend the low end. But it is a 100 pound cube when you want to move it.

Redwoodgarden,

Your post is confusing to me. Why would you define deep bass as 8 Hz, and not the 15-20 Hz available with a big sub? What does an infra integrator do? I presume shake you, because you sure as hell can't hear 8 Hz. What woofer will only go down to 60Hz? That's pretty pathetic performance for a woofer.

I wonder if you confused OP as much as you did me.
