What flare cutoff frequency are you using for the waveguide concept for the RAAL 140-15d (non-dipole)? Or is the SEOS for the DIPOLE version the only RAAL waveguide designed?

[jzagaja]

Ca. 1kHz. For both monopole and dipole 140-15d.

Thanks, that sounds very interesting. Please post when these are available.

Iwata 200 is 900mm wide and 512mm in height. What happens if I rotate the orientation and place it at 512mm as width and 900mm as height?

Any chance that you will make horns, with back chamber, for 8" drivers? Looking for horns for the Fane 8" groupbuy at

Then the horizontal and vertical dispersions would be exchanged.

JMLC-200 can be used just define back chamber.

Just conjecture on my part, but designing the crossover after the foam is in place might give better detail rather than shoving the foam in after-the-fact.

Boy, I wish I could buy a JBL 476Be, shove it in a SEOS-18 mated to a AV-15S in a transmission line

I just picked up the TAD TD-2001 1" CD.

How do I use it with the Iwata-300 when the throat of the IWata is 2"??
