Looking for mid bass horn

[Eaulive]

Hello.

I'm looking for some kind of mid-bass horn that I can load with a 12" driver to cover around 150Hz to 2kHz.

Dimensions could be around 36 x 30 x 15 inches.
I'm looking for something that could fit nicely on top of a 4520 :)

Any ideas?

Here are some plans, scroll down to the single 12" mid range.
The few that I have seen were home made.

Thanks for the links!

I was thinking about rescaling half of an altec 815... still thinking.

Try DDS horns. They offer many horns and waveguides. Their 12 inch mid horn my just be what your looking for.
