I have the workingman rig with 4004/210/115 and it works fine. Sounds good and easy to transport. I'm looking at getting a 410 now. Ampeg is good about telling you Magnet weight, voice coil size and even cabnet design. But SWR dosen't tell you anything. I like my SWR but don't feel good about the amount of info they let out. I may go Ampeg just for that reason. Also, the cost of SWR (now Fender) 410's are equal to Ampeg gear. Ampeg is from $500 to $700 and the SWR is $600. (for the 410 sticker, you can do better then that most of the time) One more Q: I want a 410 just to beef up the rig it seems like the 210s don't give me the clear stage sound I'd like at higher volumes. (sounds fine out front, I've been told). Am I thinking right or sould I be looking at it differently?
