White Wall Speakers

- Reviewed in the United States on May 8, 2020I bought these speakers to use as surround speakers in place of the satellite speakers that came with my original 5.1 speaker system so I could use those as front height presence speakers with my Dolby Atmos AV receiver. Running the test tone from the receiver, they seem to have close enough sound quality to the satellites, and they seem to sound just fine for the purpose after a test screening of the opening scene of Star Wars Ep 6: Revenge of the Sith. I also tested them with just playing music through them, and they sounded very clear without any distortion, but since they are new, I did not crank them as I want to give them time to break in. For the price, they are a great value. They are also small and unobtrusive unlike black or dark gray speakers.
I only have two issues with this package, neither of which are readily apparent from the provided pictures nor impact the performance of the speakers or quality of the sound.:
1) The speakers do not use a standard 1/4" threaded mount. Instead, they have a T-channel that slides onto the included wall mount. If the included wall mount fails for some reason, you can't just buy a standard mount to replace it. The included wall mount is made of a flexible plastic, and its durability will only bear itself out over time. I fail to understand why they would not use the industry standard mount. I doubt it's that significant a cost savings, and I would have gladly paid a little more to have it.
2) Despite the hemispherical appearance, the mounts do not pivot so you can adjust the direction the speakers face. You can't even rotate them. It's a curious design choice, especially there are two parts, but it's not really necessary in order to mount the speaker. I can only guess that the screw is in there to provide some flexural strength.
Despite these issues, I still think it's worthy of 5 stars overall.
- Reviewed in the United States on April 12, 2024Bought a pair for my surrounds in my bedroom setup and i expected to not like them but they are surprisingly good for there size and price.... perfect for small plases and easy to (hide) or not be too much on side tables. Often i smile knowing how little they are and at same time they do there job almost same as way bigger surrounds. Yes they are ugly and plastic but again i didn't bought they to take pictures.
- Reviewed in the United States on September 23, 2024The speakers may be a 3. But given their price and their ability to match the timbre of my other speakers they warrant a score of 4.
These sound pretty much exactly how you imagine. But with my older Onkyo, once calibrated, their sound blended right in with my other speakers (Neumi and Dayton). I have them hanging down above my main seating position. For DD+ Atmos and TrueHD Atmos they work pretty well. I watch/listen at low to moderate volumes on a 4.0.2 system.
Would it be nice if they were fuller sounding? Sure. Am I content with how they sound? Yes I am. Can they sound good, definitely.

- Reviewed in the United States on February 24, 2024Bought these to use as rear surround speakers. My room is pretty small and these speakers work perfectly for my needs.
- Reviewed in the United States on October 27, 2024Rear surround speakers are hit or miss in quality. These are great. Easy to install and perform better than I expected. Buy these.
- Reviewed in the United States on November 6, 2018The sound quality for these is meh. Keep in mind, if you are looking to do a THX certified type install, you are not looking at these speakers anyway. As rear speakers on a standard home theater system, they are worth the money, but Klipsch, they are not. The terminal for the speaker wire is VERY small. I had to thin out the wire to get it fit these terminals. They are the push tab style which open a hole about half the size of a ball point pin pusher. If I had the chance to do it all over again... well I would buy these again since I had a tight allowance to work with (Love you, honey). Maybe I should have saved up some money and gotten something nicer. My recommendation is unless you NEED something, move on to the next one.
- Reviewed in the United States on March 18, 2021I bought two of these just to be sure I wanted to use them on my whole setup. I've got them installed with my nice Pioneer 7.1 system, and everything I've played sounds fantastic on them. As long as you have a nice center channel and good sub, these will be perfect for any budget theater. I could be a little nitpicky on some design aspects, but honestly for how low the price is, I have no real complaints at all. I've ordered more of them now to complete my setup.
