Well there is space I. The box if I did change my Mid/Low to add tweeters.
If I put x2 of the PX22’s in one box should I link them internally in Series or Parrallel, or should I link them externally as I will be linking my speakers as I found out in a previous post “You need to connect:-- amp +ve -> speaker +ve. Then speaker -ve to next speaker +ve and finally speaker -ve back to amp -ve”. Also do you dampen high boxes with any material?

I'm still ot sure why you want 2x RX22 in a single cabinet. It will take quite a lot of midrange SPL for a single one to run out of steam matching it, assuming you don't clip the amp that's driving it... As CSG says, if the horn dispersion overlaps then you may get a less coherent sound with 2 than with just one horn. If you really want 2 in a cab then maybe try them oriented horizontally side by side on a splayed baffle...

My plan was to have them horizontal and splayed. I will probably still do x2 (x4) to a box but only connect x2 to system (as per advice)
The reason I want x2 in each cabinet is a long story (see other posts) but short story my Mids aren’t really Mids so I plan to move what I’m using as my Low (which is really a mid/low 15”) to Mids. I will get proper dedicated Lows and because I have x4 outs I will probably add a set of mids 12”. I am learning at this stage and why it’s unconventional it is actually helping me learn more as it’s forcing answers and making me understand more if that makes sense. It’s a mongrel of a sound system and a learning curve on a budget! So do Horn boxes need lining with material or not?

No, but imo metal horn flares should be damped on the inside to reduce ringing. Plastic/glass fibre ones don't need it.

And I meant to say vertically on the flare, not horizontal!!

Why do you reccomend Vertical as they are horizontal profile horns (rectangular)?

I think the dispersion pattern of those horns is 90x40, so if you splay a pair vertically at the correct angle the pattern should be around 80x 90. This would mean that the cabinet would remain slim, and it should maintain reasonable stereo imaging with a pair of cabinets. It's not something I've tried before, and it's only worth you trying if you intend to use a stereo pair.

I don’t know what dispersion pattern & 90x40& stereo imaging mean/relate to? You have to treat me like I’ve just hatched out of an egg, thanks!

With right 2" compression driver, on EV HP940, you can effortlessly hit 16-18khz. Heard it myself, that's why I have approx 8x-10x, of those units. Obviously don't expect that extension, with Fane, Eminence or Paudio Comps. You are talking JBL, Faital Pro, BMS.

How much heavy metal do you want for a pair, Mr Goldfinger?
