Using multi-subs to smooth bass response in room
Have you ever considered using multiple subwoofers? The multi-sub configuration not only provides deeper bass extension but also smoothes room modes.
I've used seven π cornerhorns by themselves in many rooms and been absolutely thrilled by their perf...

Re: Tweeter circuits for constant directivity horns and waveguides
"On the other hand, I have seen cheap compression drivers with lots of breakup in the top octave. The inexpensive Selenium drivers are a good example. Mass rolloff starts reducing output but diaphragm breakup starts making resonant peaks that increase out...

Tweeter circuits for constant directivity horns and waveguides
I have used Erse capacitors, in fact, they're in stock now and they are used on some of the crossovers I provide as kits or in finished products. I consider them to be about the same quality level as Solen caps. Here's a post I wrote a little while bac...

Re: Pi Three or Two Tower - suggestions Wayne please?
Both are great speakers, and both work very nicely on tube amps. Each has its strengths and weaknesses.The two π tower has a small footprint, low cost and deep extended bass. It is a smooth sounding speaker that is popular with just about everyone. It ...

Re: What's your favorite horn and crossover for the DE250?
I like the Eminence H290 90°x40° horn, and especially my own π wood horn. It has a straight sides, radiused to match the throat entry angle like an oblate spheroid or quadratic horn. The mouth is radiused too, to eliminate any sharp edges. This reduce...

You've got mail!
Of course, any modifications will affect performance in some way. However, the one π and two π model speakers are perhaps less sensitive to changes since they are not constant directivity speakers like the three π, four π and cornerhorn models. Speakers...

Re: Countering throat distortion in conical mid horns
I don't know why your image link didn't work, but I saw your horns in the link below. Could be the hosting system doesn't allow image links.
Good looking horns, by the way.

Conical mid horns
I tried various throat shapes and driver sizes when developing the midhorn used in π cornerhorns. I wanted a pure conical flare because it works well driven with a cone midrange and provides constant directivity. My midhorns are fairly large and design...

Re: Positioning and subs
The four π speaker uses a horn to provide uniform directivity. It is what I call a directivity-matched two-way loudspeaker. Both the three π and four π speakers are this type. What they are designed to do is to crossover from a direct radiating midwoo...

Re: Positioning and subs
I consider corner placement to be within 1/4λ through the passband. Basically within a couple feet for subs. For mains, like π cornerhorns, you want them to be snuggled into the corners as close as possible. The idea is to have a point source eminatin...
