Am I the only one having problems with MarkBass tweeters?

Good to know I'm not alone... It means these tweeters are weak, I probably will order a better one other then having tech supports with MB...

Again, there will be a few tweeter failures in any design, especially if you abuse it. Four in a row... something going on that is strange and specific to you. The good news is, tweeters (even pretty good ones) are relatively inexpensive, so you should be able to swap the fried tweeter out pretty easily. If the new one blows, then you would need to re-evaluate the situation. My guess is, it will.
 
It's good to know I'm not the only one that his MB amp can't withstand a bit aggression playing, can you please link me in PM or here? I will use Google translate, I need to read those posts to understand the situation.
 
I probably have some clips, but it doesn't really matter, my treble is flat and maybe a third centimeter boosted.

It seems like my tweeter shuts down when I play low notes and it resumes working afterward, though those are signs that the tweeter is dying...

Edit: I don't use the envelope often and even if I do I usually play it softly not causing too much lows or extreme highs.
 
Tweeters are damaged by clipping. When an audio waveform is clipped, it become a square wave, which is composed of many higher order harmonics. So you get FULL POWER of your amp at high to supersonic frequencies and poof! there goes your tweeter that is designed only to handle a few watts normally.

Since this has happened more than once, It is something in your setup or playing that is blowing the tweeter. Since the MB amp is capable of huge power output, I suggest you solve the problem before you keep trying and blowing tweeters. AT LEAST fuse it!
 
I'm sorry to say that, but if these tweeters can't handle slapping and aggressive playing they don't worth much and I should look for a better one.
Bass playing varies a lot, from soft playing to aggressive Geddy Lee and slapping, if a bass amp tweeter can't handle this, it's a design fault and it seems like it happens to a lot of people from what I read here.
I'll make sure my next tweeter can survival a nuclear blast before I replace my current one.

I love MarkBass amps but seriously &@#?!
 
I seem to recall not liking the sound of the MB cabinets with the piezo tweeter, so in addition to improving reliability, upgrading may also give you a better tone. Not sure, but I think that the piezo sounded disconnected from the woofer and perhaps tinny. It's been quite a while....

I agree with you there that if the tweeter circuit of the combo's can't handle a particular aggressive playing style without a significant number of failures, it would not be the cab for you. I personally hate piezo tweeters (at least as they are typically used in cheaper cabs), but hadn't really seen many failures reported on this website. I assume that is due to most who purchase a small combo not playing with that aggressive style. Still no excuse though, I agree.

My recommendation would be to contact MB and get a replacement tweeter, and then sell the combo and get something a bit more heavy duty, whether that be an MB head with a different cab (including some of their stand alone models with higher end compression horns and attenuators), or a different brand all together.
 
I'm probably going to change to a better tweeter or sell my MB CMD151P with the Traveler 102

Electronics are annoying.
btw
Can't I replace the Piezo with a Compressed tweeter? Would it fit and work?
 
It seems like a disease, my bass teacher's MarkBass got a blown up tweeter as well... |:
Anyone here knows about a tweeter that might fit into 151p and 121p? (Two different amps, I'm asking for someone)
Thank you in advance
