Re: Positioning and subs
I have always liked corner placement where possible. It sets the radiation angle at frequencies above the Schroeder frequency. If a sound source would radiate omnidirectionally otherwise, placing it in a trihedral corner forces radiation to be limited t...

Imaging, placement and orientation
We've discussed uniform directivity and its benefits many times here. We've also talked about the reasons why the imaging of the π cornerhorn is good throughout a large listening area, because of the combination of its uniform directivity and the requis...

Re: BUMMER!
Yeah, that's kind of how I felt too. I think what Audiokarma did was terribly selfish and irresponsible. It's not like they didn't know about the LSAF schedule in advance. In my opinion, that should have been a hard stop for them. I know I would never...

Re: How many subs are enough?
Outdoors, I would prefer the subs packed close together, ideally within 1/4λ from each other and from the mains. The idea is to create a single sound source so there is no cancellation interference between sound sources. In this case, a single sub would...

Re: Stereophile RMAF subject.
I've considered going to RMAF, but it doesn't cater to kits/DIY and that's really where I live.To me, the main thing gained at audio shows is an ability to see and hear different stuff, not so much for an in depth evaluation but more of an introduction. ...

Re: Woofer for Econowave
The three π and four π loudspeakers are both of the same design philosophy. I call them matched-directivity two-way loudspeakers. They are both mature designs, highly optimized and tested for best performance.You'll notice the Econowave uses the same ba...

Re: Bass bin as sub and reckhorn
The three π cabinet is slightly overdamped, which tends to make the bass sound "fast". It has a slow gradual lower rolloff which never gets boomy, even when parameters shift from use at high power levels or when the loudspeaker is used in small rooms. T...

Let's look at this
Are you sure the compression driver isn't damaged? I'll bet something has happened to it, possibly debris behind the phase plug or in the gap. You may have just gotten a bad driver with a damaged diaphragm or something.I ask because I've never heard or ...

Re: LSAF 2008 - Show Coverage, Seminar Recordings, Slideshows and Handouts
Don't leave out Skip Pack and Bob Brines. They generally have very good sounding systems. I regret that I didn't get a chance to stop by and listen. Too much to do!About Duke's speakers, I was able to listen briefly and what I heard sounded very good. ...

Re: SEP compatibility
By "SEP" do you mean single ended pentode? Perhaps if you tell us what amp you're using, someone here will have experience with it and can give you their impressions on how it works with their speakers. Generally, 2 watts will run any model of π speaker...
