    I bought this Acoustic amp and two speaker cabs (B600 & 2 B410s) almost-new less than two years ago. Took it in yesterday because I knew some of the speakers were blown. They tell me 7 of 8 speakers are blown. Why would this happen, and what can I do to avoid it in future?

    It happened because you turned your amp up too loud for the speakers to handle. How to prevent it in the future? Turn down.
  3. Do you use overdrive or distortion? Kick that gain/level up a little too high and it will tear into speakers. Add a Low B into that mix and it goes up quite a good bit.

    7 of 8 speakers blown????

    ROCK AND ROLL!!!!!!!

    PS / I blew the speaker on my Crate 15" combo. Wah pedal fully treble into disortion into chorus and then delay. Cranked up loud. No idea how it blew. ;)

    Basically, ANY amp is capable of blowing ANY speaker cab. The RMS rating on the cab is misleading. Depending on how you eq the amp, and how loud you play, you can blow a speaker cab rated at HALF the power you think you're using.

    Did you keep using it after you knew ONE of the speakers was blown? *boggled*

    If that were the case then one of those cabs wouldn't be making any useful sound at all.

    I was just told by my speaker repair man that the speakers were cheaply made Chinese speakers and that most of them didn't "blow" in a traditional sense, but just "quit." Perhaps poor soldering, etc.

    I use a pair of the B410s with an Aguilar DB750 and a 6 string at some pretty impressive levels over the past couple years. I can not imagine how loud it was to blow! I've played gigs w no PA support and still not even close to blowing.

    I've always played through fifteens before, and would eventually blow them after a few years, but this surprised me.

    You don't get it...you are putting too much power into your cabs. Speakers don't just eventually blow. I've got a 20 year old cab out in my garage with the original speakers and it still sounds as good as it ever did. While you can have defective speakers sometimes, there is no way in hell 7 out of 8 speakers were defective.

    Sounds to me like you have a history of running more power to cabs than they can handle based on that statement.

    You need more speakers.

    This 810 thing should've fixed that. Pending some bad manufacturing run, I really doubt 7 blew all at once. It's more likely that 1 or maybe 2 went out and you didn't notice. When you keep playing it like that, it will take out the rest.

    Sounds about right.
  16. Get your drummer a drum shield. No one should play that loud.

    That's what my grandma said.
  18. Ok but when you upgrade your speakers enough for the drummer you could blow your ears :)

    I don't see anything out of line, yet, but, it's on my radar now.
