3 things:
1-Spikes should get you more bang regardless of where you put it, maybe even a sandbag on top of it.
2-Someone taught me a long time ago that if you don't have test equipment, a great way to find the best position is to start with the sub where it is and crawl around on the floor. Where ever in the room you hear the best bass, try moving the sub to that position.
3-Bass is power hungry. If you can adjust the crossover to a lower frequency, ie from 60hz to 40hz, you will maximize the sub's ability to apply the power where you need it most. On the other hand, if you are running it full frequency, try crossing it over at 60hz or so. Why waste it's power reproducing what the MBL's can do so easily.
