Well, you were not privy do Dave's evolution back to me. He did the plans, and I did the sim, so it was a bit of back and forth once he figured out how to splice two pieces of lumber together as to NOT shrink the mouth down to 60 inches wide. So I agree with your assessment of my V3 mod. here, skipping a few in-betweens. When you can get flat to almost 30 Hz. only HT requires a sub, and I definitely am a fan of a 300 Hz. horn and 3 way for the mids, just like you.

 

I also pulled a Dubyah by "misunderestimating" the last calculations. Here's the new one.

The Maximum woofer excursion is only 1.4 mm, which is what PWK measured in the Khorn while it was at full output. So the K33 only moves 1/16th of an inch while putting out 30 Hz. at 115 db while doing 105 db at 25 Hz. using only 2 Watts while the horn is in a corner. Subwoofers you say? NAH. However, a good high pass filter is highly recommended for those who would use a 100 Wat amp with this very sensitive horn.

Now to find a 300 Hz. midrange horn (I actually own 10 drivers and 2 horns that will do 300 Hz, so may the best one win!!).

 

Which 10" DIY-able mid-range horn would you recommend?

Thank very much, please assist with hornresp input data, i have 2 Beyma 15G450 and a DAS15G , I want to simulate.

Since I did the Hornresp model, it's definitely Bigger and prevents a 3 db hump at horn cut off and gives a few Hz. extra extension.

I also have a new mod which extends bass further with outside dimensions like Dave's first one above.

Now these are frikkin' huge and not for the squeamish. However, if you want bass that's much smoother, then you need a horn with the fewest folds, like this one.

Please post hornresp input data.

The height is 15.375? There are missing measurements on the plan, please assist with areas numbered 1 to 4
