OK, use the 515 and either add a sub system or some form of EQ to get it to make any usable bass if tuned low, which usually will basically boil down to lowering speaker efficiency quite a bit. .


Yes, major mis-match even if you use GPA 411s, but then that's what bi-amping + high power handling is for.

Thanks GM, I will check the links out. How did you like the "stuff" 411 solution and why did you get rid of yours?

I have never had luck with integrating subwoofers into HiFi systems, so I am a bit skeptical. My current main speakers hit hard into the 30s and I am happy with that. So I would be interested in tuning optoins from 35Hz to 20Hz...
