A discussion of how high to vertically mount Aerial 7LCR speakers in a Trinnov SSP system with a main bed of 9 Aerial speakers (3 7ts and 6 7LCRs), 4 subwoofers and 12 inceiling Triad speakers. With Trinnov SSPs and so many speakers, you want to have a main (floor) bed of speakers, and a top (ceiling) bed of speakers.
I will have my three Aerial Acoustics 7t floorstanders up front in my theater. https://aerialacoustics.com/7t/
The 7ts are 47” high and have the tweeter towards the top. I will have six Aerial Acoustics 7LCRs for front wide surrounds, side surrounds and rear surrounds mounted on the side walls. https://aerialacoustics.com/7lcr/
The 7LCRs are 38” high with the tweeter in the middle. Am I correct in assuming that the 7LCRs should be on wall mounted so that the tweeters are at the same height as the floorstanding 7ts?
Audioguy states that the above assumption is not what he would do. The tweeters in all of his 9 ear level speakers (Triad) are identical. He would mount them so the tweeters are maybe ~6" above your ears while seated. That way, your head does not block the sound from the folks on either side of you!
Jon Herron of Trinnov gave me the following answer, somewhat similar to Audioguy: "It depends… if you listen alone (which I think you mostly do?), you are correct. Maximizing the distinction between listener-level and elevated channels is more immersive. However, most home theaters are designed for multiple listeners. In that case, we recommend elevating the surround by a foot or so above ear level and locating them slightly out of perfect alignment with any given row of seating so as to avoid head occlusion of the sound by the person sitting next to you."
Actually, I have two rows of seating. For comfort, I have Lazy Boy recliners which are I wish a little less high back. And I like to listen to music (ROON Ready ethernet) in the back row, video in the front row. So elevating the surround tweeters (floorstanding Aerial 7t tweeters are close to ear level) by at least 6" to no more than 12" higher than ear level is a good idea for me, too! Plus my theatre is 12' high, so plenty of room to differentiate between the bottom and top music layers!
What's really nice about the 7LCRs is that since the tweeter is in the middle, even if you are mounting the 7LCRs so that the tweeters are the identical height as the 7t tweeters, the 7LCRs can be vertically mounted so the top of the 7LCRs is say 18" higher than the top of the 7ts, which has a nicer appearance than if they are mounted closer to the floor! Indeed, the 7LCRs work very well aesthically and mountingwise, and of course sonically, with the 7ts. (Keep on rubbin' it in!)
