Re: H290C Horn/Waveguide
There were several influences that drove my decision to create this horn. The most important one was an observation that radial horns having relatively constant horizontal directivity sounded best to me. Objectively, they had smooth response and unifor...

Re: Pi Corner Horn Bass Bins suitable for my horn?
As you may have already noticed, I'm a big fan of the constant directivity cornerhorn approach. In my opinion, there is no better loudspeaker implementation, because it uses the room itself to best advantage.
Every other loudspeaker implementation ha...

I recently stumbled across the Pi speakers website as I searched for pictures of corner horns. I don't know how I have missed it before
The reason that I was looking for images of corner horns is that I am currently involved in a group DIY project in Au...

Re: 4 Pi and 7 Pi bass response- More similar or different?
A constant directivity cornerhorn doesn't suffer self-interference anomalies from nearest boundaries. So there is no need for flanking subs. Instead, you would want to setup the subwoofers as distributed subs, a little further from the mains and low-pa...

Re: 360 Degree Speaker?
They do exist, but I have never been a fan of this approach because indoors, it provides the wrong pattern. I don't want sound radiated at the wall behind the speakers, as much as possible.
In my opinion, the perfect setup is the constant directivity...

Re: A Smaller Constant Directivity Pi?
I've made several variations of constant directivity cornerhorn over the years. The smallest one used a JBL 2115 in a very small cabinet, only about a cubic foot. Very nice sounding speaker, I might add.
I've experimented with both two-way and three...

A Smaller Constant Directivity Pi?
The proliferation of home theater has changed the audio industry landscape. The addition of more channels has stretched the capability of amplifiers, processes and speakers in an environment now requiring as many as nine loudspeakers (right and left front,...

Re: Best Pi Speaker For Home Theater Use
Use (six or seven π) constant directivity cornerhorns if your room has the right kind of corners to support them, or (three or four π) DI-matched two-way speakers with flanking subs if corner placement isn't possible or practical. For surrounds, use one...

Re: First coil in woofer's LPF with and without helper woofers
That's kind of the point, yes. If you don't use helper woofers, then the mains are the only sound sources down low. And those tend to both rolloff sooner and shift source directivity from (baffle influenced) halfspace to omnidirectional. Then add to t...

Re: JBL2226j and DH1A in modified 4pi help
You can use notch filters for impedance compensation, but I have found them to be less than satisfactory. If the impedance peaks were consistent in frequency and amplitude, then notch filters would work very well. But the problem is you cannot expect u...
