Re: Cornerhorns - what corners are "good enough"?
My apologies, it appears I likely used the term acoustic center incorrectly. My question was directed at the LP to R/L mains separation "triangle" (viewed as if your were looking down from the ceiling).
However I just ran the actual numbers ba...

Re: Cornerhorns - what corners are "good enough"?
The measurements I do don't tell me the position of the acoustic center. They tell me when each subsystem is aligned with one another. I'm always looking at the positions of the nulls, which is an indirect indication of the alignment of the acoustic ce...

Re: Cornerhorns - what corners are "good enough"?
Hi Wayne, sorry if I missed this in the AND search for "acoustic center 6pi" i did, but where is the appx 6pi acoustic center located?

Re: Time Alignment
When you have a forward lobe that's centered with equally-spaced upper and lower vertical nulls, then your system is "time-aligned."
I personally never liked the phrase "time-aligned" because there are so many phase shifts in the s...

Re: 3Pi Acoustic Axis and Listening Distance
The center of the forward lobe is between the two drivers. Anywhere within a 25° arc above and below this centerline will give the same good response. See the link below for a video that shows measurements of this:
Measurement of the forward lobe

Re: 3 Pi plans
Flanking subs are really just "helper woofers" except that they are generally tuned to provide deep extension. That way you get both benefits - Blending in the 75Hz to 150Hz range gives SBIR smoothing and extension below that gives more deep b...

Re: Horn mouth vs. front baffle or "speaker cone"
Thanks Wayne....I'll search/study "acoustic center." I was indeed asking about the source position.
I'm my case, I was concerned with how relevant the "acoustic center" would be... if I were to temporarily set the pi mid horns and t...
