Question: Can this center speaker be mounted on the wall or mounted under a shelf or must it sit on top of a shelf?
Document: This center speaker sounds better than many complete systems. I mounted it on a shelf on top of my Pioneer tv
The speakers are mounted three feet high, and the ports (in back) are about six inches from the wall. It is important to do this to help the bass and soundstage even further.I ordered my speakers from Amazon on a Thursday, and was able to track them toward their delivery the next Monday. They were pack in an additional box and there were no signs of rough hadling.
It was dramatic. No more muddy-sounding dialogue. Incredible! Now I can turn the volume on my Onkyo receiver way down and still clearly hear every spoken word.If you're looking at more expensive center channel speakers - look no further!One thing to consider if you are planning to put this on a middle shelf where you have limited height to work with,  this speaker is 7-1/8&#34; tall,  and may not fit in some entertainment centers.
These speakers sounded nice. But I did not know you have to move at least one foot from the wall. The speakers and center speaker just did not fit my condo. I end up getting a good sound bar.
This pair of speakers are excellent for the price. I have paired them with the Pioneer center speaker and an old pair of Cerwin Vega towers with a Pioneer receiver which delivers 165 watts per channel. I must give  a lot of credit for my system to my receiver which replicates excellent sound. You have to play with the receiver remote to find the right settings to set the receiver and then the speakers will work fine. I have had these one year now.
Next came the subwoofer. I found a Sony SA-W3000 for $117 on Amazon so decided to give that one a try. I have been pleased with that as well. Then, because our TV is mounted above the fireplace and there isn't a good location for a center speaker, I needed to get something as small as I could get in order for it to fit on the narrow mantle.
My old Pioneer speakers for my surround sound finally gave out. I read a lot of reviews before deciding on these. They provide a great quality sound, and I would recommend them to anyone looking for moderately priced good speakers. Would have bought the same in a center channel speaker as well, but it was too big for the space in my TV wall unit.
No, i am back in my childhood, in my first movie theater, and I can feel the very sounds of happiness lift my spirits above the wings of an eagle!These speakers are big, so you might have to spend $100 on a pair of strong stands for the rear bookshelf speakers if you can't mount them to the wall.I'd like to give them 4/5 stars because they don't come with speaker cables and because the center channel speaker is quite big but I love the sound too much.
I must start this out by saying that I am no audiophile. These speakers paired with my Topping TP20 MK2 sound amazing! I have a full home theater setup with polk foorstanders and a center, and these speakers have an excellent sound stage and accurate reproduction. I haven't gotten a chance to fully break them in yet but the time is coming. For the price, I feel like I got an amazing deal on a fantastic set of speakers!
However, for about $100/pr, I sat there thinking - why do I spend so much on audio equipment when you can get this level of satisfaction for so little cost? Andrew Jones must be a brilliant speaker designer.I had been looking at some $300-400 bookshelf speakers for this system. Since I was trying to keep the total cost of this system very low, I decided to risk it and give these speakers a try. I couldn't be happier for the money.
Answer: There would not seem to be any restrictions in locating/mounting these little gems.  As with all  speakers, location will impact the sound quality--positively or negatively.
