This is a general question about 3.0/3.1 setup for stereo listening as well as a specific use case with my setup.
I have a pair of polk R700 currently in a stereo setup, but because of the narrow directivity above 7/8kHz It needs significant toe-in to bring some sparkle while wife want a 30° toe out (perpendicular to the wall). I love the speakers, and honestly (except for top end) there is no better option at this price point when accounting for output, front/bottom port, distortion, wide directivity, linearity and I'll first try to "upgrade" these rather than going straight upmarket at x2 price (Mofi...)
Initially I thought about upgrading the tweeter section of the r700 with SB acoustics SB26ADC with a wideguide but this would need a significant DYI effort (redesigning the midrange/tweeter crossover, enclosure reworks...) and money.
Then looking at the measurement of the R700, the beaming is starting at 7kHz and it falls pretty quickly at 30° and higher. As my speakers are at 9 ft of each other, I thought I can put a very good 3 way-center channel (polk L400 or LSiM 706c) with a L+R mix and a -6/-9 db shelf PEQ below 7khz.
My main concern is the fact that I will now have 3 tweeters for a stereo listening. Would it work ?
Then generally speaking, is there a good way to implement listening of stereo music in a 3.0/3.1 setup ?
PS: I have a LX-805 and a minidsp flex as DSP & multichannel processor.
