"Crossover Design for New Project"

Hey Michael to these eyes the Horizontal layout looks slightly better.Very Interesting !

Well, you get to chose your own poison here .

Horizontal alignment of the woofers obviously sends much less energy into the walls ( & you are in the corner if I remember correctly ) but this choice will also send more energy ( relative to a vertical alignment of the woofers ) into the floor & ceiling .

Vertical alignment of the woofers flips these energy transmission ratios .

Since most of us have rooms that give different sonic signatures of walls vs ( floor & ceiling ) the choice of vertical or horizontal alignment will result in different voicings from the speaker ( since the 2 choices interact with the room quite differently ) .

<> cheers

FWIW, I have twin woofs vertically aligned quite near walls & situated near corners and don't hear any negative contribution from, "too much energy" bouncing off the walls .
- Mind you , I do use a few acoustic treatment panels (2'x4' auralex foam ) to control "mid-band bloom" .

The off axis measurements of the T350's didn't look so good either they roll off quickly they need to be pointed directly at seating position which is what would do anyway.But maybe I could use these NOS 802-8G's.What do you think.

I suggest that you get ( or build ) a small 60 by 30 degree horn ( I'd buy one with an elliptical mouth with an exponential flare ) mated to your driver and see if you can make the relative gains work between the ( lower output 8K to 16K) UHF of the 802 versus that of your 288-8E . Your bound to learn something about relative sensitivities if you do this .
