RTiA1 review
I ordered these to compliment my Polk RTi10 floor standing towers. the RTiA1's match perfectly and i am very happy with my purchase.
I use them as rear channel speakers and when in Dolby Stereo or in Multichannel mode, i fully enjoy the sound i am receiving from these speakers.

James B on Apr 5, 2018
I am deciding on purchasing either these book shelf speakers, or the Polk Audio T15

The only thing that is making it difficult to decide is that although these speakers are larger, better looking, & considerably more expensive is that some it's specs actually don't appear as promising. For instance while the T15 has a recommend amplified power of 20-125 Watts the RTia1 is only 20 watts. Also although the T15's have a tweeter/midrange crossover frequency of 1.9 Hz, the T15 have none. These are just two things that I quickly noticed .

The increase in price of more then $150 can't be just because the RTia1, are a little bigger & have a brown wood finish, can it?
A shopper on Apr 5, 2018
  All of the internal components as well as the quality of the wood cabinet are significantly superior in the RTiA1 speakers creating demonstrably better musicality and detail in all areas of the harmonic spectrum as well as a more focused stereo sound stage.
