it's coming from vibrations. the low frequencies are causing something in the room or the amp to vibrate.

If you moved the amp to a different room, it could cause the buzzing.

Also, this happened to me, if the speaker is damaged, it can cause buzzing but will also tend to fart out as well. I pretty much blew out a 50 watt Celestion speaker with my JTM45 a while back and now it has the tendency to buzz when I play low notes and especially palmuting low notes at high volumes (it also pretty much debunks the whole myth that I see thrown around here about speakers being able to handle twice their rated wattage, I blew out a 50 watt speaker with a 35 watt amp)

would warehouse v30's be a good speaker for this amp then? its a 65 watt amp. it never really goes past 3 on the volume
