In Reply to: RE: Hornresp 1st pass - comments/critiques welcome. 40hz "L" horn posted by Oldbean2 on December 30, 2023 at 14:12:05
Hi - if it models ok, I would get a woofer with ore x-max than a 2220H. FWIW I ran 2220H in K-horn and with Bruce's "Monolith" and it distorted in the K-horn vs the lowly K33 and was out-performed by a Dayton-Eminence 295-070 15" with the Monolith
2220H may have all he power you need with that proposed horn -?
Q 2-15" eq-ed reflex box could make some noise at 40

The 2220 is the very best woofer, simulated and measured, in my Edgarhorn Titans.................as a MIDbass woofer.
The K-33 is still the main woofer in Khorns and has weaker output at it's top end vs. those with larger magnets yielding a higher bl product. For a Khorn, it uses the back chamber resonance, along with corner loading to extend the bass down. (I believe in subwoofers for low bass).Paul Klipsch even wrote a letter to you about Thiele/Small parameters not applying to Horns, but to bass reflex..........not true.
Time moves on. Don Keele and a Georgia Tech. Professor W Marshall Leach wrote about using those parameters for bass horn design.
I believe our good friends, Tom Danley and W. Fitzmaurice make great use of those parameters, along with Mr. Mcbean in Hornresp.

Or even the 3015, but I think the LF version goes high enough for my needs and will definitely go lower
And almost twice the xmax of the 2220h
Back for a bit again. Ignore me if you like.
It all depends on the SYSTEM approach to design. Sealed, reflex, tapped, or full horn? Also price is always a factor.
What bandwidth you intend to cover, how large is the ROOM, and how are you loading the speaker with proximity to the walls and corners?
Lots of woofer choices these days and there is NO "one size fits all."
I would like to cover 40 - 270hz, roughly 2 2/3 octaves; a bit of a stretch but should be manageable. Steep crossover to Oris Orphean horns above, likely a tapped horn below.
Room is 14 feet wide, 28 deep. Horns will be in corners, against side walls. With a couple of 90 degree folds they will be roughly 36"x40"x76" w/d/h. Mouth 10,000 sqcm, roughly 33.5" wide and 46" high
No WAF issues, I'm building this for my daughter and her husband. She wants a full horn system, size and looks are secondary to sound.
Back for a bit again. Ignore me if you like.
I would go with an 80-500 Hz. horn and do a Tapped horn subwoofer
I have a full Edgarhorn Titan II system, with single full horn mono subwoofer in between that sound incredible with voice coils aligned. One choke on woofer, and 1 capacitor on mid and tweeter horns.I had Klipshorns for 30 years and also Klipach Theater Jubilee Clones (no longer made) with Active Xover that went down to 30 H. with a little EQ.
Did you use Hornresp for your design to create plans or use proven ones from others? I helped a Klipsch Dealer build mine out of 18mm baltic birch 11 years ago, and got them when he passed, I have yet to finish the raw wood.
A proven folded horn (Modified Klipsch Jubilee bass bin) that use 3 12" woofers per horn, they are tri-fold, 4 ft. long 60-70 hz. out of corners cutoff) and behave like 8 foot horns in corners. 40-400 hz. is no problem. I have have a DWG file I have had all this time that I have yet to print out. I had Jubilee (Pro Theater types) with 2 12's that had a beautiful Tiger Wood veneer built by a Canadian friend, replace by the Incredible Danley SH-50 Synergy Horns that go from 40-18 Khz. in an amazingly small package as LCR in my Home Theater.
I also created easy to build Quarter Pie bass horn that are very easy to build. Nothing beats the sound of good horns.
They are 42" tall by 39 wide, 24" deep made to fit in a corner.
Here's a Hornresp model of them in and out of corners black .5 pi vs gray 2 pi overlay, black (corner) curve offset by -6 db for clarity.Let me know if you want pictures or data.
