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...

Re: Please help ID of 2 sets of speakers
The plans for my first commercially available loudspeaker model were registered in the US copyright office in 1977. I did a few experimental designs before that, but my first loudspeakers were made in 1977. The first models were just bass reflex desi...

Re: Flanking subs
Your flanking subs should work well there. I visualize the mains on stands, toed-in 45°. The flanking subs are just outside, on the floor. Each of the mains and its flanking sub are pushed out nearly to the side wall. This is a good setup. Then put ...

Re: Constant directivity cornerhorn plan request
Your room orientation is perfect for constant directivity cornerhorns. However, you will need to stick with the driver shown in the plans. Horns are pretty picky about the driver, and reflex-loaded horns even more so. The eight Pi speaker requires the...
