I have a 10" mdf sealed subwoofer box, and there's noticeable sound quality reduction through normal use. I suspect that the screws loosen and need to be tightened, but how do the screws affect sound quality? Are there other factors involved? Any advice? Thanks.

Did you build the box? Was the box built with the proper air volume for the sub being used? How did you seal it?
If the screws are coming loose then the sub does not have a good seal against the MDF and air leaks cause bad peformance.
I use 3/4" MDF with Liquid Nails Heavy Duty adhesive (in the caulk tube) Then I use drywall screws to finish securing the box. make sure to pre-drill all holes. Drywall screws can crack and split MDF easy. You can also countersink then plug and fill with putty, then sand/paint for a finished pro look.
Also good subs have a foam layer under the rim of the sub to act as sealant against the MDF. If yours doesnt go to any hardware store and get some 3/8"x 3/8" foam weatherstrip and apply that between the mdf and rim of the sub.

Maybe bad connections.. You might be messing up the wires that connect to the sub. Check your ground on the Amp and the connections at the amp and subwoofer.
If the box is becoming loose at the seams the sound would not be projected through the output hole but seap around the loose seams. Maybe the box is vibrating with the loose screws.

air mass is what makes speakers sound loud or crappy more the air less the sound
