• If the sub is in a corner, move it away from the walls slightly. Subwoofers tend to become loud and boomy in a corner.
• Experiment with other sub locations in the room to get good bass sound without creating an earthquake.
• Turn the level on the back of the sub to 50%-60%.
• Turn the crossover on the back of the sub all the way up to its maximum point.
• Set all your speakers to small and adjust their crossovers. Usually 80Hz is a good start, but you can use other crossovers depending on your speakers.
• Run the auto calibration program to calibrate all your speakers, including the subwoofer. Alternatively, you can buy a digital SPL meter from Radio Shack and do the calibration manually.
• Put a thick area rug under the sub.
• Open the sub. Add some polyfill to it without overstuffing it. You can buy polyfill from Wal-Mart for less than $5. Make sure it is flame retardant.
• Put the sub on a riser and put dampening material under it.
