Thank you so much sir, for your effort, and the time you have taken to do this, God bless you always, I follow every contribution of yours, both on face book and youtube. To share knowledge for free is the mark of a enlightened soul.
Warning: at about 52/53 Minutes in I play the horn subs...apparently the mic picked it up better than I expected and folks with in-ear monitors and or subs on their system might want to turn down the volume...
HPF for a sub completely and entirely destroys a group delay. Makes it at least 16-20msec for 40Hz or even higher. Objected. You have to filter out subsonic freqs in your phono preamp. Other sources won't have them (or you can use a phase neutral digital HPF). And thank you sir that explained a bit more how to use that Martian software (a Nobel prize to the author for that UI). If it's free, I wonder why it's not an open source, so some more experienced developers could create a human friendly UI for it.
Trying to go through all your videos and papers. Enjoying them and learning a lot! In this live video you were talking about using some sub ports solely for cooling air exchange. I was wondering if you have heard of anyone who has tried using a couple of ports with Tesla valve or valvular conduit profiles (act as check valves with no moving parts) in them to pump air into and out of the space behind a woofer. Have heard they work well with pulsatile gas flows. Could likely make square ports with these profiles using a CNC router table, although you would likely have to stack cut parts for large ports. If regular ports provide all the cooling needed, probably not worth the extra effort. Keep up the good work!
Is that the effect Danley said when transducer are within 1/4 wavelength they coupled together to produce +6dB boost in SPL? Linkwitz once answered that woofer in parallel boost 6dB in SPL and 3dB in power efficiency. But He didn't specify under how strict condition would it coupled that well.
They only couple if it's a horn loaded design. Atleast far more efficiently. You can see that in impedence plots much more than freq response. (i think the 2x 18" Subwoofer Enclosure design pdf available on sbaudience website in application section explains this)
This is one of the best hornresp video i have ever seen
Thank you! I think I'm going to do a part 2...
@@speakerscott absolutely need it!
@@speakerscott do it please
@@speakerscott Hi scott! have you done part 2? Cheers
@@speakerscott Scott this is the best Hornresp tutorial I have found. Please do part 2!

HAHAHA THE GIGGLING AT 53:27 ... REMINDS ME OF THE FIRST TIME I PLAYED MY FIRST SUB BOX

hello, thank you for this ! Did somebody put this build into AJHorn 7? what are the differences if any?

Should I be leaving the Rg box (output resistance) alone when simulating dual drivers? It seems to give me odd results when I play with it
The manic laughter at 54:00...
What program is this
