Okay, so I'm actually just starting this thread to remind myself to write a full review of the RTi A1. These are the speakers that I "won" by hosting a gathering here at my place. I tried to raffle them, I really did... but the attendees would have no such thing. I really am grateful to Polk, for providing the speakers, and to the folks who attended, for being so gracious as to give me these speakers without a second thought. I wasn't even going to be in the drawing!
Right now, the RTi's are perched on top of my SDA 2's. And I have to say, with a proper set of stands to get them a little lower, I don't know if I'd miss the SDA's. :o
Blasphemy, I know! I'm a vintage Polk guy, myself. I've owned: Monitor 5jr's, Monitor 10's and my current SDA2's. But let me tell you, hooked up to the same Adcom 545 and Hafler Pre as the SDA2's, these RTi's really sing. I got the opportunity to listen to them bi-amped with a pair of heavily modded Knight mono tube amps, and a pair of Adcom 565 monos, but the 545 does just fine.
These speakers excel at detail the way a pair of SDA's never could. At least not my SDA's. The RTi's pick out every little detail of any song you throw at them. No, they can't reach down into the sub 50hz range like the big SDA's can, but, give them credit! They only have a 5.25" driver!!!
I'm listening to them right now with Gentle Giant - "Three Friends" on vinyl, and am simply blown away at the detail and how low they actually can go, with such small drivers. I feel guilty to say.... I actually enjoy these with certain music more than I enjoy my vintage Polks. Midrange and highs are just so much more enjoyable. With a sub, I think I'd never miss my SDA's. :(
