Re: Corner horn listening distance
Since your room has a front wall span of just under twelve feet across, the best area to listen to the cornerhorns in your room is in the area between about six feet back and twelve feet back from the front wall. You can sit more distant than that and i...

Re: Definimax 4012HO - End of Life
I agree with you, 100%. Those B&C midwoofers are really nice. It's a wonderful top-notch in the upgrade path for the three π model loudspeaker. I think this 2020 version is the best that the three π loudspeaker has ever been. I also agree with ...

Re: 3Pi or 4Pi?
The three π model is slightly larger than the four π, that's true. Both have similarly sized baffles though, and they're large enough that baffle step happens right about the Schroeder frequency. So below the baffle step, we're in the room's modal regi...

Re: 4Pi plan request and question.
You've got mail! I recommend you use flanking subs with these speakers. This isn't done just to add extension, but also to provide modal smoothing and reduce self-interference anomalies from nearest boundaries. Some people also like to run one or tw...

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...

I'm curious about others success or problems using MiniDSP crossovers. I am Particularly Interested in the use of FIR filters. I was reading around here....and can't FIND it again, that steep slope analogue filters induce lots of phase shift. ...

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...
