One thing I should have mentions when using the SVT4 with two 810, you must use the stereo switch. Not the mono switch engaged. Which means both 810 will "only" receive 600w max. Its a huge drop in term of volume but still two 810 behind you. It's still massive. Trust me, the svt-4 is a great amp. I still sometimes miss it.@baxter_x recounted in post #55, when speaking of hooking up two 8x10s to his SVT-4. How else to explain his DROP in volume with more speaker surface?
Thanks!
Edit: with both of my swr 410 I didn't need to push the master too high. About 30%. With two 810,i needed to push up to 75%.just to give you an idea. But it was tone bliss!
When the wind blows your V4B away, you have a problem!
