Hey, whats up fellow BMW enthusaists. My brother (eduardov) on the board, has a 2000 BMW 328Ci and he is currently running a pretty bare system on it. A MTX Thunder 12" 9500 Subwoofer, powered by a MTX Thunder 1500 Watt Amp. When he got the system, it sounded 'alright' I thought, sure was loud for only one subwoofer. Anyways, around two weeks later he decided to get clear corners, and a few other little cosmetic modifications. His backseats we're down so the base could 'port in' and the place where we bought it from (Racehype, which is our local Car Superstore) the Owner noticed that the backseats were down, and put the Boxes in the back. Racehype is about a mile from our house (which is totally irrelevant) anyways, while we were installing the clear corners, clear side markers and some other goodies we noticed that the sub had a very small chip on it, quickly, I felt how big it was and figured it was no big deal (it only chipped a piece of the plastic cover, it didnt make a crack in the subwoofer itself. Its VERY VERY small, and he claims the his system is 'totally ruined, and does not sound right' and he says that the Subwoofer is cracking. I bursted in laughter, knowing that there is no way in hell that a VERY VERY minor crack on the OUTER shell of it (not the subwoofer itself, (the black cover), MTX put a fancy plastic cover over the sub. Basically, he is blaming the damage on me completely, while its his complete utter responsibility to check his vehicle, especially that he knew that the boxes were in the trunk, that it may hit the sub. It really didnt even cross my mind, the truth of the matter is that he 'ruined' his subwoofer, and is moaning and groaning.

I'll post a picture of what I really think the size of the crack is,
Andrew -

PS: Please post your feelings if this 'minor minor' crack could have really affected the whole tone of the subwoofer.

Heres a picture.

is it a hole that is all the way through the cone, or just a part of the plastic missing but nothing penetrated the cone itself? if there is actually a hole there then "something" can be wrong... but IIRC MTX has (like you said) a plastic dust cap over the majority of the cone and in this case of just some plastic being cracked off i couldn't imagine a difference in sound.... i am not there to hear it and did not hear it (before the incident) to notice if anything is different or wrong...

if you can post a better (close up) image of the exact damage i mightbe able to come up with a better hypothesis and/or conclusion for the situation...

also the type of box can make a difference... what type is it? ported, sealed, (please lord tell me it isn't...) bandpass? if sealed i can see it making a difference if there is a hole in the sub, but no other way can i foresee any problem

good luck getting shit solved w/ the bro... i know how mine can get sometimes too!

A little piece of the plastic is missing, not the actual paper of the sub.

That is a huge sub. Is that a new model as I have never seen it? How does it compare to the MTX RFL sub? In case no one has heard of it RFL really stands for "Real F*(#ING Loud". An MTX rep actually told me this.

Regarding the hole, if the hole is actually through the cover then it could be causing a problem. Maybe he should have put a cover over the sub. Here is an image of the RFL.

it's 34535x better than the RLF in terms of realworld use (daily setup). The 9500 doesn't need to have a box as big as the RFL would need. it also has a bit softer suspension than the RFL, translating into a lower resonance frequency. The 9500 has more xmax and effective cone area which means more potential musical output. All around, the 9500 is more useful. If you need an SPL fart-machine, the RFL will do.




anyways. Can a picture of that black thing be taken? I'm not sure what you mean by the black cover.
