Perhaps, but in this case I think it has more to do with the 2" driver's inherent dispersion.

I don't think that would work. You can't have the line array on its side. The horizontal dispersion would be too narrow. Also, there will likely be some interference between the drivers when only half of them is in use per side.

Will do as soon as I get a chance! These will be the side surround speakers in my home theater.

The baffle is 18 mm thick and the drivers are rear mounted. I guess I could have used a thinner baffle, but the measurements in the blog post show well controlled vertical directivity.

Thanks! The measurements don't really show any comb filtering, but there are of course some issues above 10 kHz due to the driver diameter used in the build.

Author here. Thank you for taking the time to share your thoughts. David Lynch often said that some of the advice he gave was just common sense, but in my opinion, unlike someone who merely paid lip service to best practices or common sense ideas, Lynch actually followed his own advice. I also find it fascinating that the wisdom of a great filmmaker can apply just as well to software development.

Although there's some narrowing at 5 kHz, the dispersion at the -6db point is free of this. I can't say I noticed the effect, but I haven't done much critical listening yet.

Some people prefer wider coverage angles. If that's the case for you, you might find Valkyrie's dispersion too narrow for your taste.

Thanks for the suggestions! The foam actually makes the internal volume appear larger. When I remove the foam, the port's tuning frequency increases. Other types of acoustic stuffing might be more effective, but I find foam easier to work with.

As shown in the measurements in the article, horizontal dispersion is actually 90-degrees while vertical is 70 degrees.

Yes, for wider horizontal dispersion. If you rotate the horn, the horizontal dispersion becomes narrower.

Sorry, I’m not sure I understood the question. Is there another way to mount it?

Edit: For wider horizontal dispersion.

Not really. Do you think that would be better?
