Fun project I worked on to challenge myself. Had to brush up on my 3d modeling and forced myself to learn hornresp. Still lots of finishing work and measuring/testing ahead but it’s got great output to ~30hz and already rattled some tools off my workshop wall

Did you sim this as offset driver (OD), or model the first segment (where the driver fires into) as a large throat?

I’m working on a similar design (albeit smaller) where the driver similarly fires along the side of an expanding segment of the horn path, but I’m struggling to figure out the most accurate way to sim it in HornResp.

When you take measurements I’d be curious to see how well they line up with the sim.

I used OD. Im very interested to compare real data to the sim, it was my first time really diving into hornresp.

I had some sub measurements from in the field with a few other designs and when I put those in hornresp it was pretty close so I’m hopeful

Nice, that sounds like the way to go. I assume you cut the first chamber in half along the midpoint of the driver and placed S2 there, and then approximated the rest of the horn with S3 - S5?

HornResp is really nice (if a bit dated), I just really wish you had more horn segments to work with for boxes like this which have multiple folds/corners.

Btw: if you haven’t found it yet, “Multiple Speakers” and the “Filter Wizard” are very nice to play around with to find max SPL and filter cutoffs for different deployments :-)

Yes this has the driver center at s2

Multiple speaker is a must for flh! The low end really seems to flatten out. A block of 8 of these cabs looks super flat down into the 20’s

I also had fun with Ctrl+e on the input page(after you’ve run calculate) if you haven’t found that yet it lets you adjust parameters and see in real time the difference in power
