10db may be a little much since about 6 db is perceived as "twice as loud"... I still don't think it should be rattling though.

I run my ep 500 at about 80 db with all others set to 75. Occasionally during an action movie I increase the sub level in the receiver from -2.5 to -1 db which offsets this a little more... but that is usually at an 'average' listening level.

does the noise sound like it is comming from the driver or from the amp?

Ken, the screws tighten into threaded metal sleeves... do you think over tightening would really strip the MDF? It seems like it would strip the theads on the screw or the sleeve, or strip the head of the screw.

Either way I wouldn't over tighten anything... maybe tighten about a 1/4 of a turn or so.
