If you don’t have a Niles MSU-140 and/or MSU-250 hub you will need a new system, specifically the MS-220 and MF-1’s. Please call 1-866-224-6171 and talk to one of our reps — they can walk you through what needs to be done and help answer any questions you might have.

The biggest concern I have is that placing speakers into each corner separates the channels more than usual. In a typical home theater setup, the center and L/R speakers are placed in a cluster by the TV, with the subwoofer and surround speakers placed for sound and convenience. That setup works because the soundtracks from movies and TV shows are modified stereo, with supporting surround tracks to “fill” the rest of the room or parts of the room, such as in 5.1 surround. It creates a spacious feeling.

Now, if you’re just listening to music it shouldn’t be as big an issue because the reflected/spacious attributes of the Acoustimas system will make music sound even better, especially with your vaulted ceilings. So the placement is determined by the primary source of music — radio, stereo tracks, surround tracks, movies with surround sound, etc. But you also have to consider sound volume: the farther the speakers from the listener the weaker the volume, which means the volume will have to be turned up higher.

If you have to place the speakers in the corners, or if that’s where you want them, then put them there and then adjust the speakers into a direct or reflect orientation: the speakers can be twisted to concentrate or disperse sound.

I assume you’re worried about image burn-in. This used to be a problem years ago when HDTVs first became available, but recent developments have basically made it a non-issue. Plus, new HDTVs are packed with features that make game play even more exciting, such as high refresh rates, bolder colors, better sound and expanded connection options.

So, will gaming systems ruin your new HDTV? Probably not. If the TV is left on 24/7 at its full brightness, and if the screen remains static, then there may be some degradation soon than later. But keep in mind that panels are designed to function for dozens of years without noticeable loss of quality — and that’s with punishing testing standards.

I won’t comment on guidelines because that’s something parents and their kids need to figure out. Remember that the TV doesn’t care what it displays: if it’s on and showing content it’s being worn, regardless of the source.

The systems will sound great whether they’re connected to a TV or playing music. In fact, the Bose systems are designed to perform great regardless of the audio source.
