Dunno if this is the right forum for this, but I don't know where else a p.a. question would go.
I just got a Peavey xrd680 plus (300w per channel) and one Peavey speaker with a 15 and a horn for my son's band. They have another homemade cab with a 12" 200w Carvin speaker in it that they were using with their old PA.
I hooked everything up, added a monitor for the drummer, and it sounded good when I did a vocal check. However, when we gave it a band test with the Mains on about 7 and the vocal channel mic on 5, the homemade cab starts feeding back immediately. I found that if I drape a piece of canvas across the front of the speaker, the feedback stops. Pull the canvas away, the feedback starts again. And this is with no music or singing going on.
I took off the speaker grill, covered the inside of it with a towel, and screwed it back together. Turned on the PA, got feedback.
The cabinet has a horn that doesn't work and two holes maybe 4" across at the bottom.
Any ideas what's going on? Any ideas about how to fix it, other than just leaving the canvas there? Though the cab does look better significantly better under canvas ...
Thx!
