Possible Problem with SUB-12

Read this from the Manual:

For optimum performance, place your subwoofer in a corner of the room on the same wall as your front channel speakers.(refer to Figures 1 and 2).
Please note that room placement can have a dramatic effect upon the performance of your powered subwoofer. Corner placement, as suggested above, will increase the amount of bass output, while placing the subwoofer along the middle of a wall, or out in the room will decrease the amount of bass output. Experiment with a number of different placement options and control settings to find the one that best suits your particular room and taste.

Actually, I did that when I had them in my living room (a much larger space, which is why I bought two) and had mixed results. I finally got decent performance when I had them with the ports facing the front corners, about two feet from the wall - I have a slanted ceiling, wave propagation is just bizarre in there. Sat on the couch looking at it, it's all good, then I went to adjust the angle on the right rear surround and the volume boomed up something fierce - it was much louder there. And it was all reflected sound, just horrible.

So I threw in the towel, went out and bought the JL Audio, and just brute-forced it in there.

I moved the SUB-12's into the family room, an open area that's almost impossible to get decent placement in (I promise to get pictures up by tomorrow) and one of the amps promptly gave out. Just dead. So BB replaced the amp (they were only about six weeks old) and they've been good since then.

They're actually by our Mom & Pop seats, almost like Buttkickers, but again, decent placement is horrible. I'm building up my custom passives to sit in a TV alcove, under the set, can't put the Klipsch's there because of port placement.

So one, or both, is going to my youngest after he gets back from Kuwait. I like them, but they're probably best in a room with a lower ceiling, and smaller in size.

My oldest has all Klipsch, including this sub, in a small place he got, and it sounds terrific - and not pushed hard, either. I like the SQ, at medium volume, it's a good sub. You just need to find the right spot for it, if it exists in your home.
