Re: Horn mouth vs. front baffle or "speaker cone"
I think what you're talking about when you say "fore and aft" is the acoustic center. It's the position of the sound source - The point in space where sound originates.
This is most important when phasing with other sound sources for proper...

Re: Two Subwoofers
Outside and inside are very different.
Outside, you want all sources to combine coherently. This means you want sound sources grouped together, and their acoustic centers aligned.
When two subs are placed at each ends of a stage, bass suffers from...

Re: Build Thread: 2Pi Towers, 6Pi Corner horns (and possibly a sub and center)
As I write this post, the replacement drivers have arrived safe and sound, and I am still waiting on the replacement cross-overs and my 3Pi Subwoofer parts. All the major construction of the 6Pi is complete, and only a handful of small parts need to be...

Re: Build Thread: 2Pi Towers, 6Pi Corner horns (and possibly a sub and center)
So, how do they sound? Good.
How good? Very.
They sound so good that I felt compelled to take a break from working on the 6Pi's so I could deal with acoustic treatments. Flaws in my listening room suddenly became intolerable.
They sound so good I found ...

Re: Build Thread: 2Pi Towers, 6Pi Corner horns (and possibly a sub and center)
Before I even began making the CAD drawings, I was worried about finishing. If the hulking monolith of the 2Pi gets a low WAF score, the 6Pi Cornerhorn gets a total fail. Fortunately, I no longer have to worry about WAF scores, but I do prefer things to lo...

Build Thread: 2Pi Towers, 6Pi Corner horns (and possibly a sub and center)
Greetings everyone!
This post will be mostly introduction and planning. At the time of this writing the 2Pi Towers are all but complete and in service, and the 6Pi mid-horns are in the last stages of construction.
Introduction:
Almost 20 years ago,...

Re: Midbass slam
I have not measured my room, in a way that I can look at a graph, but I have run sweeps and hz test tones.
I had discovered a huge null at 70hz (throughout the center of the room) and another at around 150hz.
I have since added considerable acoustic...

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: 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: 4 Pi speakers (Yuichi 480FL horn)
Those are beautiful speakers! I always loved Yuichi's wood horns. They are partly what inspired me to make my first waveguides, which were made of wood. Now I make the H290C waveguides out of plastic, using an injection mold. Makes them much more cos...
