Hello all, I just had a situation come up I've never had happen before.
I started playing an album and about 1/2 way through the first song a loud machinegun sound started coming from the mid-bass driver.
I then turned off the preamp and then turned on again, started alright and then the sound again.
The system; HK Citation pre-amp and power amp and custom speakers with a C-C crossover. The pre-amp was reconditioned 19 months ago, so it should be good.
So would it be the driver or the XO?
