I have a carvin RL1-18 and I am conseerned with the amount of movenment of this speaker. How much should this move? I am pushing it with 350 wats and it is rated at 600 watts so i dont think that it would be moving to much. But when i hit y lowB it is moving alot. Also do you think a 2-10 SWR or a 4-10 Peavey TVX would be Better to add to this I they would be getting another 350 watts.
