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...Confused

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.

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!

Probably some of the best 2" Horns ever made, very few in UK, EV Spec states response up to approx 20khz, with right driver.

So Won't be cheap..

Very few people over the age of 30 can hear past 16KHz, I suspect most people in the sound system or PA game have much above 14KHz unless they are children!…


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?
