I have the Ashdown MAG 400...400 watts with 4 ohms and 200 watts with 8 ohms. I have the Bag End S15 D but I like the sound of a 410 rig. Our band has two 18" subwoofers. I'm looking at the Carvin 410 with 8 ohms and the 210 with 4 ohms. Would the 210 give me the stage punch of a 410 and would it be louder because the Ashdown would be putting out 400 watts? The only thing that I don't like about 410 cabinets is their weight.
