help with my cabinet problem...

[xshawnxearthx]

so last night i'm playing a show, and i turned around to notice my two top speakers in my ampeg 610hlf looked like they had lights behind them. like every once and awhile, they would light up.


i realize this is bad....anyone know about this?

I have blown out horn fuses in some of my cabinets before. I was aware of this by the bright light eminating like a flash behind the speakers. You may have blown a fuse, does the horn on your cab still work? how many watts are you putting to the cab?

well i'm not familiar with the cab, but here's a guess...............

a lot of tweeter equipped cabinets use a car dome light as a fuse to protect the tweeter. when the current to the tweeter gets on the high side, the light tends to light up before burning out. These light/fuses are typically mounted near the crossover, sometime on the back of the jack plate itself. I'm betting that this jack plate/light is located near the top of the cab and you're seeing this light shine through the surrounds of the top two speakers.

From the Ampeg website 610hLF info page www.ampeg.com

"Cabinets using high frequency horns contain a variable level attenuator. To prevent overpowering and damaging the horns, a resistive bulb is wired in series with the horn for protection. "
