When you get to this level of fine tuning, measurements mean less and personal taste reigns supreme. The kind of music, room and hearing damage to the lister become critical. I personally need about 10 systems. One for TV/Movies, one for Pink Floyd, another for Nine Inch Nails, yet another for Nirvana. Then there's the women- Tori Amos, Stevie Nicks, The Wilson sisters, Dusty Springfield... There is no end!

I get it. I have a Sony STR-DA4ES, same as yours, but a touch less power. Maybe missing a zone, not important. What you need to do is get one of those cheap AV input selectors. Use it to choose different configurations for your subs. If you solder the L and R leads together inside, you can eliminate your Y connectors, too.

This will likely get me in some hot water, but here it goes.. When a speaker manufacturer produces a speaker with a built in passive crossover, they (hopefully) try to get the best response from the cabinet/driver combination that they are utilizing. Simply removing the internal passive and going with an active frequency crossover, cutting the signal at the proper point and removing power robbing components from the signal path seems good - but: shelving, notch filtering and any other response correcting processes from the original crossover design are eliminated. Now what? To get it right - in YOUR space with YOUR other components, you need to use a microphone/analysis process to make things right. Simply going active without the additional step can be counterproductive. I'm looking very hard at getting the MiniDSP to give it another try. YMMV.
