B&C DCX464

I've used both the 464 and 1440. The 1440 is a very well behaved driver and simpler to integrate than the 464. If you are crossing the 464 passively it quickly becomes quite complex to get good results.

The LTH142 would be the waveguide of choice. I used a custom wg for both drivers.
Thank you very much, this combo is now high on my list of considerations! But I would be using DSP to cross them and am not averse to extensive EQ, if that makes a difference. The only thing that matters is what combination can provide the best possible end result when done right, using DSP.

Please elaborate on your custom waveguide. Thanks
I used the HF1440 in the next generation of this loudspeaker, the A For Ara H3.

The DCX464 was tested in a slightly smaller waveguide.

They look excellent. What are they made out of?

How did you find their sound?
In what ways will the next generation change and are there anny audible changes they are going to hopefully fix/improve?

Cheers to you hopefully having a bit of fun with that project!

H3v2 is a little smaller, lighter, has the same F3 down low and goes louder. It is also easier to make because most of the stack lam is machined as one piece. v1 was glued up after cnc.

Their sound? Big headphones that can go stupid loud down to below 30Hz.

The IG page has some renders of the inside of v1 to give an idea of how the bass horn is folded around the MEH.

How low are you crossing the hf1440 and what did you find experimenting with that? You mentioned they can go very loud, so I'm sure that factored into your chosen crossover point. If this was for a domestic living room that didn't need such high output levels, how low could you comfortably cross that hf1440 (assuming a large enough horn) and maintain sound quality and output? Assume avg SPL target of 85-95 ish. It's fun to have the capability to go louder but critical listening will be >85 over 90% of the time.
