Re: Horn loaded Corona Build
Hey guys! I just wanted to weigh in on how impressed and happy I am with the 4 Pi speakers. I started with them in a small room of an open plan house. Wow. Even with a 50 WPC PS Audio Sprout amplifier, these pressurize the room. At reasonable listening vol...

Re: room and amp questions
I always recommend constant directivity cornerhorns for rooms that can support them, and our DI-matched two ways with flanking subs for rooms that can't. Rooms that work well with our cornerhorns have two corners with unobstructed walls extending from...

Re: Futzing with vibration control
I think John was saying that four Pi mains with flanking subs were close to seven Pi's, but that he preferred the cornerhorns. That squares with my experiences too. Where I can use constant directivity cornerhorns, I do. They don't need flanking sub...

Re: H290C Horn/Waveguide - closest equiv. in 1.5" or 2"?
It has been almost seven years since Wayne posted this amazing analysis and explication of waveguide optimization for room use, and a compelling case for the H290C. I bought my pair and I'm convinced. For a different system though I want to use a larger...

Re: 7 Pi & 4 Pi plans
Please pick which model you prefer and let me know. I'll send the plans after you've decided. Usually, I suggest constant directivity cornerhorns if you have the right corners. But if you don't - or if you want to have speakers that are more versati...

Re: Small horns
I did make a five Pi model for a while that was pretty small. And I even made a cornerhorn with an 8" woofer, which was even smaller than the five Pi model. There's no harm in making a constant directivity corenerhorn that is small. The expansi...

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: Joe's basement
Bruce is getting up in years, that's true. But he's got a keen mind, so while he isn't as spry as he once was - and definitely hasn't been lugging speakers to shows in a while - he is still sharp as a tack. But Bruce likes the tractrix horns and I li...

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...
