Those look cool!
Here are some things to consider, test and check:
Phase angles, crossovers and baffle spacing

Re: 3Pi and 4Pi Plans Request
I think if you peruse the Pi Speakers FAQ and do searches here in the forum, you'll probably find all the answers to any questions you might have.
In particular, you might want to read the H290C Horn/Waveguide thread. It discusses the benefits of tha...

Re: H290C Horn/Waveguide - closest equiv. in 1.5" or 2"?
I put all of my focus on the H290C, and it's predecessor, the H390C. That was a wood horn/waveguide with the same profile but with much more mouth radius because it was designed to be free-standing and therefore have no baffle loading. But both are for...

Re: 4Pi crossover with 2226H and D220Ti+QSC PL-000446GP?
The QSC waveguide is pretty close to the H290C in its acoustic properties; Even the acoustic center is pretty close. So the crossover is close too. I am taking this inferrence from the measurements made by Skywave Rider a couple years back. But the wa...

Re: 4Pi crossover study
The π crossover will not work very well on the SEOS12 because SEOS horns have too much ripple. Designers using this horn usually incorporate notch filters to get decent response. To me, this is a deal breaker. That's why I did not adopt that horn in m...

Re: One Pi Speaker
Hey Dude,
1 Pi's can be sized very small if you need to hide them (less bass but that's ok for surround). The Alpha 8 can work in cabs down to .5 cuft sealed so basically you make the front baffle just big enough to hold the drivers (with the proper dr...

Re: Another Happy H290C Fan...
That's very good advice, Scott. The H290C waveguides were designed to be used on a baffle. They should not be cradle mounted like our H390C wood horn/waveguide is usually used.
The reason is the H390C horn/waveguide is large enough to support the wa...

Re: 2Pi's completed - now I want a center channel
Only a few inches .... wuhahahaha! Here is my crazy plan!
Build 3 Tower 2Pis.
Lay a Tower 2Pi sideways underneath the screen (put the tweeter on the right of the woofer when standing up). So, you have a Tower laying sideways under the screen with t...

Re: H290C Horn/Waveguide
Thanks for the thumbs up, guys. I'm really proud of it.
As many of you know, but some probably don't, this H290C horn is a molded plastic implementation of a horn I developed about ten years ago. It's the horn shape I always wanted. For many years,...
