Use room acoustics to your advantage. Place the subwoofer in your typical listening position, and then walk around the room until you hear the bass you're hoping for. Then place the sub in that spot where you were just standing -- that's the best spot in the room for your sub.
Check that the ProMonitor speakers have a single large threaded insert on the back. If so, then most of the cheaper floor stands will work with them, though they may not be as elegant as the Definitive stands. Stability can also be a problem, so pick a stand that looks like it has a hefty, wide...
Get a pair of Definitive StudioMonitor 450s and buy or build a pair of stands that set the speakers at just the right height. I've always been impressed by the bass that comes from those small speakers, which use side-firing passive radiators to get low, and Definitive's ability to design a...

I have a tremendous amount of respect for Cambridge Soundworks, which hasn't lost Henry Kloss' commitment to providing a high price/performance ratio, even though Kloss passed away several years ago. I have a Cambridge Soundworks MicroWorks II at my PC (not Kloss-designed), and I'd put it up...
Try unplugging the subwoofer from the receiver's LFE output, and see if it continues to make the strange sound. If it does, then the problem is inside your subwoofer. It may be that the amplifier is toast. I'm not sure what amplifier oscillation sounds like, but I had a set of PC speakers once...
Any hole in a speaker enclosure, if not completely airtight around whatever you put in the hole, will create a leak and wreck the acoustic bass loading of the enclosure. So be careful -- anything you do will need to be airtight.
I can say that I loved the sound of the PowerMonitor speakers I heard at a nearby Ovation store. They're capable of room-rattling output with low distortion - really an excellent concept, and nicely executed. The bass really packs a punch if you want it to, or you can dial it back if you're not...
