Yesterday I played at a studio because it was too late in the evening to play in my garage. They provided me with an Ampeg AVT350 w/ a matching 410 cabinet. After playing with this amp for a few hours I think that I can hear myself more clearly. I guess that is the "Throw Phenomenon" of 18" speaker. So now I am wondering about my setup. I use a Carvin RC210 with it's matching 18" ext cab. I am guessing that I hardly hear it (my neighbors probably do though!). I have been leaning more towards replacing the 18 with a second 210 cab to simulate a 410, but have not been able to try it out yet. If I do that, am I going to lose all of my rumble? I don't need so much bass it shakes peoples teeth out, but a little tremor here and there is appreciated.
