What’s the deal with speakers with horns? Agreed, but equally important in the discussion is that it's wrong to assume that the designs for home are designed to be heard at a distance 10x the listening distance. The good ones are very much designed to have very wide and tall coverage patterns...

I once picked up some speakers locally that were a gift to a local supplier of tooling from EV's top engineer/designer from the early 70s. They were about 35 cu ft using a 30" woofer, 2 12" midbass, a large mid horn and a biradial horn tweeter. I brought them into the living room when I first...

Our ears are sensitive to early reflections. It's why most of us treat the first reflection points in our room with some absorption. The idea with avwaveguide, when properly implemented, is that they can significantly reduce the occurrence of early reflections and at the same time, promote the...

Thanks for the link, Swerd! Let me have a look.

Sure thing. Earl Geddes is a good starting point. A forum member named "Zilch" did a lot of work implementing the technology from JBL, Geddes, and others. There are threads all over the internet about "econo-waveguides" or econo-waves with loads of measurements and reviews. Geddes on...

If you ever get an opportunity to listen to a Yorkville U15, try to do so. It's not quite as refined as some high end horn systems I've heard, but for a commercial PA product it gets very close. It's capable of superb performance but isn't particularly cheap.

I think the people in that thread are aware of the performance of the TD15M and may have cautioned against the use for another 15" driver. For the subwoofers, I didn't look closely, but if he is using multiple subwoofers, he may be using a distributed bass system, which is another well...

The science behind constant directivity horns is solid, established and well understood. The same goes for small room acoustics. A great deal of the SEOS waveguide projects you'll find on the internet are based on this. If you were implying that it's pseudo-science, I'd suggest you take...

Very good list of questions: I don't know that it's really the compression tweeter that makes it sound better, it's the waveguide. Waveguides can be effectively used with dome tweeters, as well. What they allow is very wide and constant dispersion. Typically, a dome tweeter will do well on...

I ran across this thread and can shed a little insight, not as the poster in the referenced thread, but as someone who is a fan of the approach he is taking and some of his equipment choices so bear with me. I'm not offended by being grouped with him or of the disdain for his approach, but I...
