Re: 6pi Mains, 3pi Center
I like to place the mains at the lower edge of the screen when used for home theater. And I like that to be somewhere close to ear level seated. But since the forward lobe is clean 20° above and 20° below, there's plenty of wiggle room. I prefer not t...

Re: Plans for 8pi speakers
Sorry, you're right that 0.5ft3 would be way too small. That's the minimum size for the midhorn when used on constant directivity cornerhorns as a dedicated midrange. The eight π loudspeaker uses a vented rear chamber that doubles as the bass-bin, and ...

Re: Johnny5's four Pi build
If you have two good corners, I'd suggest building constant directivity cornerhorns to take advantage of them. They are designed for that placement, and maintain acoustic proximity to the boundaries appropriate for the wavelengths involved. The bass bi...

Re: Help with new design
That's an important requirement. The cone driver has more displacement by virtue of larger surface area and higher excursion capacity, but regardless of that fact, this particular midhorn really needs to be placed in near proximity to the corners. It n...

Re: Help with new design
The problem is you can't consider any horn or waveguide to be generic, because they all manifest specific characteristics and those must be accounted for in the crossover. The directivity, passsband, acoustic center and acoustic load are different for e...

Re: 7PI questions
Thanks Wayne.
I had already dug through the FAQs a bit prior to posting and will continue to do so, rather than expecting you to re-address topics already covered elsewhere.
Just so it's clear where I'm coming from, I feel like I should explain myse...

Re: Speaker placement and wavefront launch, revisited
I tend to prefer constant directivity cornerhorns in rooms like that, with them placed in corners at opposite ends of the short wall. The best listening area is just beyond where the speakers' axes cross. See the link below for more information.

Re: Speaker placement and wavefront launch, revisited
I got your email and replied. But if you didn't see it, I'll post the jist of my reply here.
The best way to do what you're saying is to build the seven π cornerhorns, as shown in the plans. They are designed to be true constant directivity cornerho...

Speaker placement and wavefront launch, revisited
Hi Wayne,
I'm finally able to access the forum! I sent you an email about Four Pi loudpeakers but I've been having issues with my personal email, sooo...
I'd like a copy of the plans but I also asked about designing a corner bass reflex (or Jensen...

Re: Will 7Pi work in my room?
The floor won't be a problem, provided the room doesn't sound resonant from panel vibration. Most times, room modes are the biggest problem anyway.
Curtains almost always help, and constant directivity cornerhorns benefit even more because there aren...
