OK so here's the situation. I just got an Acme B4 2 nights ago. I go it used, off of a fellow Talkbass member. I used it tonight for the first time... it sounded fantastic... that is, until I engaged the "bright" switch on my BBE Bmax preamp, which promptly caused the tweeter protection bulb to burn out. OK, no big deal, right? This happened halfway through a song, so I finished the song with no tweeter. I'm getting ready to take off the grille and speaker, and someone says "I smell smoke"... the smoke odor is coming out of the Acme! After taking the grille off and a speaker out, I see that everything inside of the Acme is fine, the bulb is just burnt out. Is it normal for this to happen? I'll be more careful in the amount of highs I send into the Acme from now on, but I don't want to freak out the rest of my band by playing a cabinet that smells like it's about to go up in flames. Is there any way to keep this from happening again? I'm sending about 1800 watts into it, through a QSC RMX 1850HD, but I don't have the gain cranked at all. It really does sound good, but this has me concerned.. One last thing.. do I need to replace the gasket on the speaker that I removed?
