Why is it when I have to set up against a wall it doesn't sound right

All speakers are designed to be either operated against a wall or boundary surface or operated in free space. It has to do with the design of the speaker dampening characteristics. In short, most speakers of this type are operated in free-space, so the manufacturer has optimized the speaker for this. Unfortunately this leaves it less optimized when mounted in corners or on or in walls or flat surfaces. It's a choice when the speaker is designed.

I am not sure why...but it might be the timer. I love the system though. It sounds really good and I do not have any rpoblems with it.

Yes. Make sure that you place it near a wall and the base will sound richer.

What you're describing doesn't sound normal so it doesn't sound like it's working correctly

Can't answer why but I can maybe help. I put a 10 lb weight on the top and that seems to dampen out the noise.

The manual recommends experimenting with the distance to the wall as moving them closer reinforces the bass. This effect was noticeable where my speakers are located and they are 4 or 5 inches from the wall.

Make Sure Your Mike Is Not On And To Close The Speakers. Plus Check The Cables Make Sure they're Properly Connected. Or Check Your Bass Maybe It's To High

Elizabeth... Not sure exactly what the problem is. I have mine set up through an amplifier and is primarily used for music at a spa where I have several rooms with speakers. Maybe the amplifier has been switched to another setting where only background sounds are coming out as if it were surround sound speakers where only backgrounds are heard. Check setting on amp. Let me know what you find...Steve

This is the real problem with having such a large center. Sounds Great but your almost forced to have it underneath your tv. You could get some sort of mount and put it above. Personally mine is below the TV and it doesnt sound as great

Your inputs probably have power or signal or cable issues. The Rolls boxes do not create noise, just pass it on. Rarely has any of my Rolls stuff failed in any way and I have been using them for years for stage and club bands.

Sounds like interference, not the wall. Did you add/change Wi-Fi routers, cable modems, electric appliances, etc around the time this started?

Not on ours. The sound is clear and volume is appropriate. Something isn't right!

I have not had this problem. Position of the speakers in the room makes a difference, close to a wall or corner can affect the amount of bass reflected. Def Tech has allowed for this and placed a knob in the back towards the bottom that allows you to decrease the amount of bass of each individual enclosure. Other than this, you would have to decrease the bass output from your receiver.

Agree with others--probably just need to adjust your receiver settings or check your sub. My receiver and sub sound great in my room and even outside for gatherings.

The wires are probably gone bad. Or broke a bit try adjusting. Or could be feed back from your environment. The microphone is sensitive

Remember to screw in to an 2x4? Its heavy and try to put a bit of foam or something to take the vibration of from going into the wall? Also center speakers are made to b put in front of th listener's or angle ur speaker down ? This is very important ! And vrak in the speaker for 40-50 hrs of mid high volume? Face the speaker 1 inch from the wall and turn it up for a while. This speaker sucks until u brake the 8 inch speakers in? This is important! !!!! Have fun ,and enjoy !!!!�

This is actually a great question. As the others have said, the backs are open, which is typically not an issue when installing into a wall or ceiling. HOWEVER...if you install into a ceiling that has blown insulation above it (the loose cellulose kind, not the rolled fiberglass kind) then you WILL want to come up with your own way of keeping the loose insulation off the backs of the speaker. If you don't (as I didn't the first time I bought these) then over time the quality and volume of the sound will lessen because of the insulation working into and pressing against the cones. I had to replace one set because of this problem. This is actually a great question.
