MB Quartz speaker issue

[Rmack]

Is it normal for these speaker to blow? I just noticed two out of the 4tower speakers where blown. It's a 2012 and I don't really play the music that loud.

I know they aren't the best but they shouldn't blow that early.

Its as normal for a speaker to blow as it is a tire. If they are truly blown, there is a reason they blew. If they are just not working, then theres also a reason and it just requires some investigation.

Both speakers were ripped at the top

First thing I would check is to make sure the amp is set to hi-pass and not full-pass or off depending on the amps nomenclature. Full-pass could be causing over excursion. Are the surrounds contacting the grills? Other then that, it could be a bad batch of speakers will low UV inhibitors or low quality bond between the surround and basket.

had one speaker blow and one crossover blow. Still a mystery because I never had them cranked (and rarely on)...

Damaged surrounds on 6x9's is somewhat common because of the shape of the cone. You see that all more frequently on a -x- speaker than you do on a round speaker.

That's not a "blown" speaker by the way, just a torn surround. Blown is usually the term used when the voice coil gets overheated and the speaker crackles, pops or quits working all together.
