I figured out what was causing the phase issue, it was the receiver. Apparently the receiver does something funny where if I have the center speaker set to small and towers to large and using 7 channel mode, with correct polarity on all speakers, it throws the towers out of phase. However, if I have everything set to large, they are all in phase. I prefer to have the center set as small, therefore switching the polarity on the back of the towers is no issue. Prior to figuring this out, I did call RBH and spoke with a gentleman by the name of Shane. He advised me to do a few tests and to follow back up with him as to what I found, which I did. At first I didn't know who Shane was, thought it was just an employee there to provide me some customer service (great customer service nonetheless), but to find out this guy was the VP of engineering and he took the time to speak to me, it meant a lot. He didn't try to rush anything to get me off the phone, we just talked for a bit and I even asked him about his opinion on some receivers, which had nothing to do with my original issue. Super nice guy and very knowledgeable.
Wanted to also mention that I've had a few issues where the cloth material on the inner part of the grill frame was coming loose. At first I only noticed it on my R515 and reached out to RBH to see what I could do to fix it myself, I wasn't looking for a replacement but more of guidance. They said they would send me a replacement but said for me to check my other grills to see if any of the other ones had issues so they could send replacements for all of them. I did find that both my R5's also had the material coming loose in some areas. I'm thinking this is probably due to the type of adhesive they used and/or the surface area in which they apply the adhesive was just too small based on comparisons with other speaker grills I have. I asked if maybe they could just send me a bit of the adhesive instead as they didn't need to send me replacements, so I could repair them myself but they insisted on just sending replacements as it would be easier for both parties. Can't say enough about the level of service RBH has provided, truly awesome. It's hard to come across companies nowadays that provide this level of customer service.
Again, I haven't had much time to play around with my new speakers besides trying to figure out the phase issue. Been dealing with a lot of other issues lately and just haven't been in the movie room at all. I did, however, read audioholics review on the R55E's and since they are professionals, I'm sure their unbiased review and write up is much better than what I could ever say. I do agree with them regarding the lack of documentation as I didn't receive any either, so I don't know if this was a cost cutting measure as they have this information posted on their site for viewing.
But just from my short listening sessions with my Impressions (not the Elite versions), wide sound dispersion, clarity and low bass extension for what they are. One of these days I'm going to crank those bad boys up and see what they can do. Coming from the BIC PL89s where the horn tweeter was handling both mids and highs, these are a major step up for me. The only small regret I have is that I kinda wish I would have spent the extra cash to order the phantom blacks due to the vinyl peeling in some corners. I know there is a 30 day trial but the cost of shipping these back wouldn't even make sense anymore.
I agree with you Elihawk, audioholics write-up was a pretty negative positive review. It was a good read. Hope everyone has a wonderful weekend!
