Can you describe each buffer??
I wasn't thinking of specific buffers here Richard. Rather building different ones and choosing the best for each job.

Firstly,I dont see data.

With a total of 8 12" bass drivers and insignificant basshorn volume I would expect direct radiator loading at bass frequencies,not significant horn loading.

Horn loading or not on those bass sections, they sure do look good. If they sound half as good as they look, who cares about the horn. With 4 12's per side you probably don't need it.

the "you are there" vs "they are here" is something very interesting to me

my harbeth p3esr + sub or atc scm7 v3, in my treated room really sounds more like "they are here"
my jbl lsr32 in my untreated living room is clearly more the "you are there". personally, I prefer the "they are here"

Default Reflections

Imo reflections are the mayor reason that reduce the "they are here" experience
Reflections are also inside the speakers.. These can be tamed to a large degree. Opeb baffles are dipole so always out of phase. Placing far away from the rear wall helps but youd almost have to devide your room in two....

Default Cardioid

Haven't read all the posts but real world size horns are monopoles at very low frequency. They become increasingly directional as mouth size increases and frequency rises.

You could put two horns back to back, reverse polarity to the rear one and add delay for full cardioid performance.

Actually has any one done that or should I patent it now!!

Depends on the reflections. With the right delay and dispersion the opposite can be true

Horn vs Open baffle bass
Having had a listening room (lava cave) that was hypo-echoic thru the audio bandwidth, the Here/There thing became completely recording dependent. Sometimes it was even both in the same recording. For example a close mic'd singer in front of a large orchestra could be both "here" for the singer and "there" for the orchestra.

Once the room really isn't fighting you, it's amazing you'll find in the recordings. Or sometimes disappointing.
