My three front KL-7800 THX in-wall speakers were originally placed too high on the wall and the tweeters are much higher than ear height when sitting in my home theatre.
Even standing the tweeters are higher than the ears.

Is it ok to reverse the speakers so the tweeters are below the main driver, this would at least make the tweeters a bit lower?

Hard to say. Try it, see what happens. More specifically remount the left or right and see if it changes the position of the central image.

If it was easy I would just do that to test, but I have a screen that's laced to the wall, I would have to pull down the screen to just try.
Would be easier if someone could confirm its ok for the sound to reverse the speakers.

Yes, putting speakers upside down is perfectly fine. However, it's not usually a good idea to put speakers on their sides. In that case content around the crossover frequency will arrive at different times from the woofer and tweeter. I know you didn't ask about that, but I thought it's worth mentioning since that's another common question.

I may be over-thinking this but...

Some wall-mounted speakers might have a preferred mounting height. The primary axis might be tipped down so that they are optimal when mounted higher, which can happen with wall-mounted speakers.

I agree that 90 degree rotation can be more of a risk.

I think THX speakers are very directional especially with the horn design. If I move my head up and down the volume of the voice certainly increases when my head gets closer to the centre of the horns.....

See if the manufacturer has any recommendations/guidelines for installation height.

Klipsch don't mention anything about the height they should be placed.

Klipsch came back to me:


Hello Murray,

Yes, the speaker can be mounted in reverse so the tweeter is as close as possible to ear level. Please let me know if you have any other questions or need anything else.

Best regards,

Yes Murray, THX speakers are designed to have limited vertical dispersion characteristics so as to minimize Floor and Ceiling Reflections!

Your subjective experience moving your head up and down certainly demonstrates this!
