What customers say about "Size & Weight"
Polk Audio RTI A1 Bookshelf Speakers (Pair, Black)
  • Otherwise, these RTi A1s appear to be very well made. The cabinets are heavy and solid.
  • They were solid, not overly heavy or bulky and could easily be placed on a bookshelf.
  • I can't believe my ears. These things are so small! I never expected this much sound from such a cute little set of speakers.
  • The big sound filling my living room was coming from these little Polk Audio RTI A1s.
  • These things are NOT super-light-weight, and I would not be comfortable putting these on a wall unless I could attach directly to the stud inside the wall.
Polk Audio RTI A3 Bookshelf Speakers (Pair, Cherry)
  • The speakers are very long which might cause some of you discount these for back speakers on surround sound but not me.
  • These Polk Audio sound really nice. The sound coming out of these little speakers is amazing.
  • I was at first put off by there small size then pleasantly surprise by there amazing sound. very happy with my choice of Polk Audio RT1 A3 bookshelf Speakers.
  • My only complaint is they are relatively big to be "bookshelf" speakers - these barely fit on my shelf.
  • They are a little big so you'll need a larger area to position them.

What customers say about "Audio"
Polk Audio RTI A1 Bookshelf Speakers (Pair, Black)
  • Excellent speakers and great value. These speakers have great lows and mids, and a little light on the highs, but overall crystal clear. I
  • The soundstage and imaging are all stellar. As was the case with my Polk Audio towers, I feel I can reach out and touch every vocalist and instrumentalist.
  • These speakers produce an amazing soundstage, clean, crystaline stage.
  • Simply put, they sound great! They blend perfectly with my fronts and have a surprising amount of bass plus great midrange and treble.
  • These speakers not only look fantastic, more importantly, they also sound phenomenal.
Polk Audio RTI A3 Bookshelf Speakers (Pair, Cherry)
  • I had purchases Polk in-wall surround speakers for the rest of the room, but needed bookshelf ones for my front. These are great. Super solid and nice sound.
  • The lows are surprising, the double porting really works.
  • The sound is clear and tight. The midrange is unbelieveable. This is not a super hissy high tweeter either.
  • I can best describe the tone of this speaker as "wood". It is natural, warm, solid sounding. The punch of the bass is precise.
  • Highs are great, voices sound very natural and distorted guitars and drums sound very life-like.

What customers say about "Features"
Polk Audio RTI A1 Bookshelf Speakers (Pair, Black)
  • Real wood veneer cabinets is a nice touch and something you rarely find in this price range.
  • These speakers have a vary small footprint, and are designed to be easily mounted to a vertical surface. Really nice enclosure, and finish.
  • The quality of the assembly of the speakers is solid and the curved design work great in my dining room. Reccomend.
  • I was snared by the beauty of the RTI A1's and also by the design of the cabinet (which was very similar to the BS22's, only these are deeper from front to back).
  • I received these speakers about a week ago and have to say, they sound amazing! They are built of quality materials and feel very sturdy.
Polk Audio RTI A3 Bookshelf Speakers (Pair, Cherry)
  • The wood is beautiful, smooth and on bottom, top and sides.
  • The finish is as good as any furniture and the front cover is a good fit.
  • There are two posts on the back that hold the bottom of the back of the speaker away from the wall.
  • The speaker has two sets of posts. The come connected together by copper strips. Pull the strips off and each speaker can be bi-amped.
  • They are finished with a beautifully done cherry veneer with a flawless satin finish. The curves on these speakers are enough to make you weep.
