Sounds like you are experiencing acoustic feedback. Are your woofers pumping?
You may need to relocate your turntable to a better location. You want to keep it away from the speakers and the corners of your room. If that does not work you could try putting it on a wall shelf.
Another way to deal with it is to purchase a rumble filter which basically filters the bass below 20 hz.
I recommend trying all other options before using a rumble filter beacause they can degrade the sound a little.
