I experience something similar with the the philharmonic BMR ( second gen) and ascend LXs. But to me the tonal balance wasn't quite balanced to begin with. There was a slight but low q treble emphasis which made all speech hissy/sibilant (not in a painful way), sounded clear but sometimes difficult to understand.I know this thread is a bit old, but I wanted to thank everyone for these comparisons. I have the Sierra RAAL towers, and I am getting upgradeitis and was leaning heavily towards the 226be, but it seems it may be a bit of a waste. I've been through about 5 pairs of towers, and these are the most perfect yet.
The main problem I have been having is hearing dialogue in some movies. The clarity is there, but it always feels like dialogue gets lost in the mix. So I turn it up, then the music and sound effects are blasting (even with the lower dynamic range setting on my receiver). I attributed this (maybe incorrectly) to the wide disperson, but I know most of the dialogue is coming from the mid driver, so the biggest problem may just be my untreated open living room and my farther than average seating distance. I know it has to do with the way a lot of movies are mixed as well, but I still feel like I may be able to do better. Any center channel I have tried only makes things sound worse/boxy. I have been itching to try the Horizon, but as you all know, it's difficult to fit this into a clean cabinet setup without breaking out a saw.
My other option is a more narrow dispersion speaker like the JBL HDI series. That may help with the seating distance and possible wall reflection issues, but I'd be sacrificing overall sound quality and the enveloping aspect.
Thanks for any further input you guys may have.
I found the revel f206, kef R3, ls50 meta and my current Linton's didn't suffer from this at all. These speakers didn't accentuate anything, but easy to hear all dialogue clearly. The overall presentations we're more balanced. These speakers also tended to sound better with a larger variety of music genres as well.
Edit: If I was in the market for speakers, I would get the f226be, ls50m or Linton's, mayeb a couple subs and then retire from this website.
