Impressive work!
Are there perhaps any clips of the synergies (with the dcx464) "in action"?
I guess some of us would love to get an impression of the way these sound. A decent smartphone or DSLR camera would suffice to capture the vocal range.

Hi William,

Your Aras look absolutely fantastic.

One Q: Have you had a chance to compare the B&C DCX 464 to any of the Be drivers out there (e.g. Radian or TAD) - and/or to the BMS 4594HE? In that case I would really appreciate your thoughts - thanks!

Best regards
Peter

I come to the conclusion that mid chamber and port lengh can be tuned to exactly compensate for the volume of the horn so that in hornresp sim, compensating effect can be seen, and there's no more the first dip in mid response, and neither in high way. Is it about that ? I don't explain well, but if it is, you'll understand.
In my specific and maybe extreme case for example, the magic happens with 2 liters front volume for one 8" speaker only as mid, but 24cm port.
Sorry for the off-topic, i'm opportunist

I've not heard any Be drivers. I've used the BMS coax's before. Systems were too different to compare. Both drivers got the job done.

It's not just me, it's a small but dedicated team committed to build some very special loudspeakers.

Yes, so I see! Thanks for the photos, the work is impressive and inspiring.

Interesting that you went with round ports for the woofers.

P.S. The archive photo from Kolbrek&Dunkers Horn book (a fantastic book) shows how relatively modest sized the docali horn designs are. This is when they discovered how important it is to put units on the drawing.



I've been thinking about the enclosure construction, there are a lot of variations, but I feel like maybe I underestimated the amount of size I have to work with and was thinking that i might be able to use TL for the bottom and mid woofer.

I have a question about Tl's, what if I designed a TL where the volume of the Line wasn't big enough to house the Driver motors, how do you compensate for the driver chamber or is this just not recommended?
