Default Supravox mid bass drivers a good match for front horns?

400-2000 SUPRAVOX

Call me mad, thinking of using a jordan jxr6 in a tractrix horn (300-400 hz) and matching to one of these. The supravox wd fire upwards (omni) and the horn wd be placed above... not sure if this has been tried before or if its a good idea, but I am thinking it might help with phase alignment.

There are much less costly alternatives for the bass, like this:
CIARE ITALIAN SPEAKERS - PRO AUDIO B2B: NDH 15-4 S SUB-WOOFER
and much less experimental ones for the mids like this:

cheers dude. will look at those now. What attracted me to those french units was the very low Fs - the 120 w handling is adequate.
I also saw a v cheap Eminence unit on Parts express which looks ok, bass into the mid 30`s

The main question is, will a front horn treble/mid married to an omnidirectional mid/bass work?

Yes, low resonance is not common in the pro world. I think Beyma also had sub-30 Hz drivers but are no longer produced.
300 Hz bass is still omnidirectional anyway with a 15" driver, orientation doesn't matter so much.
What are you going to use as a tweeter? What would you think about a Stage Accompany with horn? Are you going active?

That Supravox 15 is basically their version of the Altec 416 woofer. Its usage would be similar.

Your goal was using horn loaded fullrange, right ?

means lowish xo point, I guess

If so, you might have a good chance

but a lot depends on your xo work

there was a member lately, showing a fullrange in Le´Cleach horn with dipole like open back
I dont know, but to combine dipole top with omni woofer I could imagine phase issues between woofer and back of dipole top

But with closed back top/horn I dont see any issues

I have a woofer placed on its magnet, directly on the floor
no box, no nothing
Im not sure what really happens, but it works well
other than it jumps and rattles when loud

people look very amazed when they hear it and even more when they look at it

Looked at the Great Plains site at their Altec clone- the Supravox still has the edge on specs. Looks like this or a pro 15" is the only way to go but wd be nice to find a 12" with a good power rating, decent bass/low fs and 95 plus DB...still looking!

Yeah tinitus, hoping the little jordans wd work - they are around 86 db so I don`t know what output they wd be horn loaded..
Is sound really non directional below 300 hz?

If yu seriously consider using a BIG woofer in omni, you will need one with a relatively light cone, and very stiff suspencion

and you end with no or little lows

you may find a nice woofer in the 18" FH series from Faital
put in a nice 200liter box, closed or BR

Or why not a PrecisionDevices, handbuilt by your own country men

If you can live with lower efficiency the Peerless 830669 is one killer of a 12" woofer. Super clean and can take loads of power without strain. Easy to crossover, too. because it is well behaved.
