The idea was these could be used as a 'stand' for either project.
I'm tempted while funds are still a little scarce to purchase two of the Beyma's and get them built into simple mdf boxes, and i can purchase another two in the near future and build the cabinet I really want. Will give me a chance to test them out, play with the XO, and make sure the cabinets work in their said frequency.
As for the horn idea, i have a BMS 1" tweeter that i wish to make either a JMLC or OSWG, there is a spare channel of active XO and power to have a mid inbetween if necessary.
Have been eying up the MiniDSP PWR-ICE125 for eventual sub/subs.
Thanks for your input Line Source, much appreciated.

Here is the idea for the combination with a horn:
An externally hosted image should be here but it was not working when we last tested it.

Studio Au,
I am thinking of using this Beyma driver as my 2-way speakers system, my question is have you heard it being driven as part of a speaker system? If so can you give me your impression especially when compared to other woofers?

Be objective !
It's just a 10" driver.
Is it the foam surround model, like the 12 BR ?
So it's a classic 10" paper driver with foam surround.
Does it has stamped or die-cast basket ?
It must be with stamped chassis to keep cost low.
So a 10" driver with good q/p
Would I use a 10" driver with a tweeter ?
Yes, I did
Till the ferrofluid dried 🙄😡
So, now the 10" ( altec, from mod. Three ) stays unused.
As the big boxes that contain them.

I haven't heard them, so no subjective viewpoint.
These are going to be designed for 100Hz and below. But I would like to test how high they can play, to eventually find a neat solution from bass cabinet to a horn in the region of 300Hz- cut off frequency.

Used in the Linkwitz X521, thinking maybe the Seas L26RO4Y could be a better option, one per side for now, and an easy upgrade?
Or just stick with the Beyma's. Too many options...

I'm running a test box similar to what you are looking at. Pairing the 10" beyma with a DNA compression driver and the seos 12 horn. I'm currently in tweak mode with my minidsp setup. So far so good. My goal is to make a small, good efficiency, wide range floor stander and the beymas range with the comp driver looks like a good idea.
Beyma do a 16ohm version of the 10BR60, so you could do an isobarik enclosure, wire them in parallel and they'd only require half the internal volume compared to a single driver.
Beyma 10BR60
Beyma 10BR60
could they be 'wired' in parallel with the DSP and active with enough power to drive them with ease and easy on the amp?
Really like the rear mounting!
Do you like them?
How high are you crossing? What size cabinet?
Wondering if two will do, four would probably be better?

I'm still working out the XO. My shop test enviro is not ideal and I'm tuning my test setup as well as the xo. 2 10s would work well with the comp driver. I had to dial down the comp driver to play with the single 10. The sound of the beymas is great. Great detail and they reach down low in the ported cab. The comp drivers need some taming. Will update as I go.
OK so I finished up tuning my test cabs last week. Couple learnings from this exercise that are relevant to your thread:
Keep the Beyma's XO as low as possible. I started the XO at 1500 and it was too high. I dropped it down to LR4's at 900 (pushing the lower limits of the compression driver) and the sound improved dramatically.
Midbass/Low end on these sounds great. Reaches down into 30 Hz in my room. No sub needed.
These can play LOUD w/o breaking up the midrange.
Now its time to figure out what a real cabinet will look like....

Once again, poised to buy. To be paired with a Radian 850pb, also poised to buy...
@Rolloft, any updates?
Do you have any plans for your cabinet? Would be keen to get something knocked together for testing.

Going to try and make a start on the cabinet this week. Only ordered 2, so 1 per side.
Square or rounded?
I'd rather not make two, and the CNC and bendy ply makes light work of doing curved cabinets.
Sealed or ported?
Make cabinet to accommodate a possible second driver?

I did a ported cabinet that i had modeled on winISP based on volumes that I could work with. I still want to plug the port and run some FR curves and listening tests to see what happens. I'll give you some more details when i get home this eve.
Up to you if you want to run more than 1 driver/side. If you are concerned about bass extension, 1 should be plenty unless you have a really big room. If you are looking to reduce distortion in the midrange at higher volumes, 2 would be better, but I haven't heard much distortion at ear ringing volumes with 1 thus far.
Also, try to keep that XO as low as you can for the beyma. <1k sounds good to me. If your compression driver can't do it, might go 3 way...but then that sort of defeats the purpose. I'll post more info tonite when i get home.
