Hey guys: What would be your recommendation for a GREAT pro amp for a Tumult? I just ruined my AV-15 by trying to drive it with a crummy 380 watt Rythmic Audio plate amp. I would like to state for the record that it is NOT a good idea to try to push an AV-15 with only 380 watts. I figure to prevent this from happening again I need a decent amp. I've got around $1000 to spend on the amp. First, no plate amps. I am not going to cut a hole in my Acoustic Visions box because that'll make it pretty much impossible to retro-fit if the need should arise. Also I think there may be a need for a rumble filter to protect the sub, especially the way I will be prone to driving the thing...(could one use a BFD parametric filter as a rumble filter???) What are you Tumult users using? Any suggestions, comments, ideas? Thanks Much Jeff S.
