There shouldnt be alot of mechanical noise...Didnt you recone those Subs...if so, they might not be aligned perfectly.

yea hot carl one does kinda click every now and then

they both make a little bit of noise though, just not clear, but i dont expect them too

it still plays just makes a funky click when it changes notes fast, but dosent happen alot

i just got one fixed from not even playing right, it works fine, but the other one just makes clicks some

i might just live with it, im not waiting like 3 weeks for it to be fixed too

Mine makes the clicking sound on occasion, normally at a lower volume and certain notes, just a faint little sound though. Hope it's normal for some of them

The gap is UBER tight... doesn't surprise me, not to mention they were designed to be all out SPL subs, they probably aren't too concerned with noises on the MT unless it's bringing scores down.

tight gap, no pole vent...in fact no venting at all... yes, its going to make noise.

They vent on the top side. slots in the basket that you can see the coil through. Would not hold up good as a daily sub with no vents //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

that is the basket/spider venting...the motor it'self has no means of venting. With a gap that tight the air behind the coil doesnt have anywhere to go. except to sqeeze around the coil and then get sucked back down.

I amnot trying to say you are right are wrong, but I woudl like to understand how those vents are not cooling the coil.

MTX Website (Didn't they start those vents? I am not sure, buit I think so):

"Spider Plateau Venting is characterized by twelve ½"-wide x 3/4"-tall vented aluminum grilles in the 8000 Series. These grilles surround the voice coil between the motor structure and the spider, the area of the woofer that gets the hottest. Cool air is directed in and warm air is pushed out of this key area allowing the woofer to handle lots of power while keeping the voice coil cool. This translates to an all around better performing subwoofer. All of these features add to Thunder8000's cool factor - literally."

I have a set of these subs at home in the closet, and no pole vent.

Maybe there is something different in the basket used in the MT, but just by design, air has to be moving in and out of those vents when the coil moves in and out, assuming the dust cap/top of the coil is sealed.
