Slight static-ey sounding noise from a new driver...

I replaced a pair of 6.5's recently on one of my M10's....well there's a definite slight static-y noise vibe coming from only one of the drivers sounds more apparent sometimes on voices...but its not specific to it.

I can't say I've overdriven them...my bro was here...helping build a shelf....did show off a bit...but not past the half mark on the pre-amp...altho it is new power to me. Really tho it cranks out bass just fine...but will exhibit the zzzz vibe here and there on it as well.....the other driver is fine....I can't say it's blown....but somethings up.

Arrgghh........strangulate me!!!!

what is this fizzle....and will it fizzle away?

I think I traced it...it has 1 missing screw cuz I didn't like the way it was going in so I filled it..to re-tap it later....when I press on that corner....no more zzzz....sound right to u guys?

Air leak... the basket is probably vibrating against the cabinet.

I drilled a new hole and threw the old screw back in....problem went away....very very happy....I didnt think I went too far the other day....but to be sure I've over balanced to the other speaker.....shhwoooo what a releif.
