    • Good value if you want to add Atmos satellite speakers
Style: Hi-Res Height Speaker (XT90)
I bought these to sit on top of a pair of Onkyo tower speakers and they fit perfectly. They seem to add some dimension to my surround theater. However, I question the hype about them bouncing sound off the ceiling and doing tricks. I have a Dolby Atmos capable system but maybe not the best room acoustics to take full advantage. But good value for the money. ... show more

    • Tiny sound with a boom.
Style: Hi-Res Height Speaker (XT90)
You might think the size of these would only be below whispers, well, no! These small square speakers produce amazing sound and enhance sound if paired with the XT70 Polk Towers. Great quality and care put into the build and design; highly recommended if looking for a change or to upgrade your system. ... show more

    • Good Speakers
Style: Hi-Res Height Speaker (XT90)
Honestly, can't say I recognized to much of a difference when I added these to my 7:1 surround sound, but it was minimal and at the price point I got them for, $79.00 on Amazon, I would say it was worth it.

    • Excellent speakers for ATMOS "If you know what you're doing".
Style: Hi-Res Height Speaker (XT90)
Excellent ATMOS speakers for the price. They can be mounted as Upfiring to reflect off of the ceiling; sitting on your towers, or wall mounted facing toward the main sitting area; as front height speakers. If you know what you're doing, these speakers will work for you and your ATMOS. If your ceiling is more than about 9 feet, upfiring speakers don't work well. Bouncing off of a ceiling takes some acoustical physics. But if your ceiling is less than 9 feet (like a basement theater room) then these can be a decent option. I actually use 3 sets of speakers for my atmost. These plus 2 other different brands. ALL 3 sets are up firing, but these polks sit on my towers, the other 2 pairs of speakers are mounted close to the ceiling on an entertainment wall unit. They still reflect off of the ceiling, but they are only inches away from the ceiling. (For those concerned, my receiver only has output for 1 pair of atmos speakers. My other 2 pair are 8 ohm speakers. I put them in parallel to give me 4 ohms; then these polks are 4 ohms so I put them in series with the other two that I've connected, and now I have 8 ohms again). Definitely worth buying if you have low ceiling OR if you're going to mount them at the wall/ceiling and point them down. ... show more
