It has nothing to do with resolution and format.

You are partly right here. But I have a lot of classical recordings incl. guitar. I also have been to a lot of classical concerts incl. classical solo guitar.
My own experiences is way back. It was two Bruel and Kjr 4011 a Soundtracs Jade-S 48 channel console
and Studer 827A tape recorder. Traditional mic setup. One pointing to the bridge and one to the middle of the fretboard.

I've worked extensively with Peerless 2" driver and SEAS L16RN-SL.

Use of Peerless driver down to 200Hz is nonsense. IMD performance is horrific. Even with 1000Hz 24dB/oct crossover point distortion from transients is apparent when driven even close to live for acoustic music.

The SEAS driver on other hand has exemplary distortion performance within intended bandwidth, up to a bit past 1kHz when driven with high power transients.

I've tested all this.

Cutting this driver at 200Hz is a complete waste of its use. It's design was tweaked from bigger SEAS drivers for use by "SL" in his Pluto design.

Trevor Marshall's design is garbage.

Much better to lay SL's Pluto on floor with tweeter pointing up.

I've stuffed my DSP based Pluto Clone, using L16RN-SL and Peerless 2" drivers in room corners, and imaging is no better than when used in my preferred near field set up, but virtually entire image appears outside of the room. Not a problem for me when listening to symphony, but not so good for intimate jazz and such. SPL at greater listening distance is more limited. Casual listening is nice, but isn't why I go to concerts, and isn't why I enjoy great recordings, or why I'm so heavily vested in my setup.

With Pluto clones laying down and tweeters jammed into corners pointing up, imaging is degraded. Image height is totally smeared. Granted, I've got acoustic tile ceiling, fully carpeted floor, and well furnished room.

When I listen to boombox in empty room while painting it, this is enjoyable too, but is completely casual listening with nearly constant movement. When I clap my hands in empty room the "boinking" slap back sound jumps out of corners, and fills room briefly with this decaying echo. Music on boombox with spaced out transients has same effect applied, and becomes tiresome interference to listening with intent, instead of painting. It doesn't change much when boombox is place in corner, somewhere along wall, in center of room, up on ladder. Boink.

Still, I keep open mind, that certain rooms, with right treatment (level of furnishings), may produce generally acceptable sound field for some people.

A farmer may get a certain satisfaction wrestling a pig to market. With a crippled horse, he will shoot it and be done with it, the only satisfaction being knowledge that it was the right thing to do.

why into corners?

"no better" = not worse?

what do You mean by "entire image appears outside of the room"?
You mean that all virtual sound sources appear far behind the front wall and the side walls??

again - why into corners??

>1 kHz upfiring in the corners?

very weird setup to say the least, I think it just couldn't work

well, interesting, perhaps You could start a new thread "listening to a boombox in a an empty room" or perhaps "wrestling a pig to market"

My Pluto Clone speaker purely omnidirectional to >2kHz.

Speaker with tweeter jammed in corner = tweeter in corner pointing at ceiling = up-firing.

Works like crap compared to normal near field setup = "no better"

Yes, your experiment is kind of weird.

This horse is dead for me.

Bye.

yeah, its been mentioned already once or twice in this thread, the new Shahinian Larc is another example of a FCUFS design of this kind
