DIY Orelo (Orelo/Orelino)

Bert, thanks for the email and pic on this. It looks fantastic, well done.

Trying to get some ideas from the guys at the Altec Forum is hard work....you need to be a scientist to understand what they're saying.

But, I just love the simplicity of this Orelo horn.

Can you please provide a quick response to the following:

1. If only two drivers per side are used, do you need to put a 'top' on the bass horn? (I would use a mid horn mounted on top if so.) Sort of like the horn in this pic.

2. You mentioned the Altec 416 woofer would work OK. I already have two new ones from Great Plains, so I'd need two more. Is this because it is a low q driver? Are there many differences between this driver and the specs of the BD woofer?

3. What is the depth, height and width of the 'half' horn?

4. How do I calculate the horn flare?

5. Can I run the horn up to 800Hz cleanly?

Thanks and regards.
