Re: Corner horns & flanking subs?
Constant directivity cornerhorns don't benefit from flanking subs. The anomalies created by reflections from nearest boundaries when using traditional loudspeakers don't occur in cornerhorn installations. The sound source is acoustically close to the n...

Corner horns & flanking subs?
So working from home, due to the quarantine, and daydreaming/planning my retirement stereo system. I have not really decided between 3Pi, 4Pi, or 8Pi speakers. It will depend on the house we move to after retirement, and the room I put the system in.
B...

Re: 4PI Plans Request
You've got mail!
We all love to see build threads. So please create one and post often!
As for the mods you are considering, I am glad you understand the potential for anomalies from standing wave modes in large full-range cabinets. That knowledg...

Re: 4PI Plans Request
The flanking sub low-pass recommendation of 100Hz second-order is empirical, so you can consider it a starting point and not a hard-fixed number. However, I have found that the slope is always better being gradual than it is being sharper. Fourth-order...

Re: MiniDSP
Digital filters are awesome because of their flexibility.
In the case of loudspeakers - and particularly controlled directivity loudspeakers - you have to be careful with your choice of filters because they affect summing through the crossover region....

Re: Three Pi and Three Pi Sub Plans
Thanks for the great response; that's exactly what I was trying to understand. Again, the design seems very elegant, and I wish I could accommodate the cabinets in my room.
I have been thinking about building a baffle wall, however, as I already have an...

Re: Three Pi and Three Pi Sub Plans
What you propose sounds like it would work pretty well. You would lose a couple synergies that are designed into the three π and four π models though. And you would need to test your design with acoustic measurements, paying special attention to the lo...

Re: Definimax 4012HO - End of Life
Do not forget that this design almost requires flanking subs for deep bass response. You can consider it to be a three-way design with the woofers detached.
They are adequate without subs, but certainly not optimal. They get better bass extensio...

Re: Definimax 4012HO - End of Life
I'm not ready to make an announcement, but I can give a status update.
I have a pair of Eminence Delta Pro 12A woofers and a pair of B&C 12PLB100 woofers here to test with.
Both look like they will work very well from modeling and from free-air...

Re: WinISD 0.44
That's approximately the same size box I run. It sounds great in that size box. I tune mine a little below that, which as you said, gives the system an overdamped alignment. I like that because thermal shifts don't push towards underdamping, but rathe...
