Re: H290 vs CH3
Both the CH-3 and the H290 are good horns. They each have pros and cons. The CH-3 does look flimsy, I agree. When I first saw it, I was skeptical about its performance. But it provides amazingly flat response and good coverage. The CH-3 has a diffract...

Re: Flares for PSD2002 in Theater Four Pi.
I prefer radial horns to pure CD horns. What I like is constant directivity in the horizontal plane and collapsing directivity in the vertical plane. This improves uniformity of the reverberent field because the energy distribution around the room is nea...

Re: Sound and perception of sound
Nice post! I wouldn't dream of deleting it. I agree with you, by the way, 100%. In addition to amplitude response, I think the impulse response is important, and I think a large dynamic range is important too. Another item that is rarely considered is ...

Driving motivation
I agree with you. I prefer the effortless dynamic range of a high efficiency speaker, and the low distortion of a driver used at 1/100th the power it was designed to handle.I design loudspeakers because the choices I would make aren't found anywhere else....

Re: Pi Speakers for HT use?
It's a DI-matched two-way horn loudspeaker, meaning crossover is made where the direct radiating midwoofer narrows to match the directivity of the tweeter horn. This provides smooth on-axis and off-axis response, smooth directivity and a more uniform reve...

Re: Stage monitors -- doubled Pi 4s?
The four Pi loudspeaker is designed to use a midwoofer and tweeter, and the crossover frequency and positions chosen were selected so that the directivity is matched at the crossover point. The woofer pattern begins to narrow from being almost omnidirecti...

Re: Thanks for the reply
All speakers beam at high frequency, depending on their dimensions. Even a 5" midrange will begin to beam above about 3kHz. That's where it's angular coverage has collapsed to a 90 degree cone shape. It will continue to get more and more narrow above th...

Re: Probable dumb question - Where's the midrange driver?
That's a very good question. Thanks for asking, giving me the opportunity to explain.The three Pi and four Pi loudspeakers are what I call DI-matched two-ways. They have a high-efficiency midwoofer that operates through the midrange, into the overtone ra...

Pi horn design philosophies
Pi Speakers are best described as high-efficiency, controlled directivity loudspeakers. They've always used high-efficiency drivers like those from Eminence and JBL. They evolved from my early designs concentrating mostly on flat amplitude response to ha...

Making speakers "disappear"
Sometimes, I hear phrases like "prat," "soundstage" and this particular one - "making speakers disappear" - and I'm somewhat at a loss for what the person is trying to describe. Could be a lot of things, so I have to try and ...
