I preferred not to overthink the problem. I raised the sound.

My old Von Schweikert VR2 speakers had a rear facing ambience tweeter. The soundstage height seemed stuck at speaker height so I cut up an index card, glued it between two 1/8" pieces of MDF, painted it black and used double sided carpet tape to attach it below the tweeter. Voila! Soundstage height along with a cavernous space up to the ceiling behind the speakers.*

EPI is a name that seems only vaguely familiar. However, the name Winslow Burhoe

EPI was big when i was going to Uni in the early 70s. Burhoe went on to Genesis Research and is now carried on by human.

“That they are standmounts is irrevelant”  I am forced to ask how you came to this conclusion

Irrelevant in the sense of the thread title. But typically less volume than a standmount, and no “apron” in front reaching the floor means a standmount will typically have less bass potential and without the reduction in baffle step from the plane reaching the floor.

Would a lot of diffusion and/or absorption behind the speakers raise the height of the image?
Or just create more depth?

I can dig it. A consistent coloration irrespective of source material solved by dollarama felt over the tweeter template.
Makes you wonder why Von Schweikert or the guys that made my loudspeakers didn't think of it? I don't wonder, it’s anechoic response or unimpeachable source material and componentry. Welcome to the real world.

Thanks Dave,

Properly implemented, it will transform your system. Search, "Late Ceiling Splash" on this forum.

Many builds were done and the castle version (driver on the top, driver on the front) became the favoured. Easier to place in more rooms, and while an artifact of the ceiling reflection do have a soundstage of greater height.

The Castle version reminds me of Dick Olsher's Samadhi Ichiban speaker (https://www.blackdahlia.com/the_new_and_improved_black_dah1.html) with its Ceiling Boundary Ambiance Enhancement, also a little bit of Roy Allison's RDL speakers (http://www.classicspeakerpages.net/library/allison/rdl_acoustics/rdl_acoustics_brochure/).
