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...

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.

Hey, at 51:09 you talk about the air exchange and how this is used for cooling the driver(s). I was wondering if this could have a (negative) effect on the audio when the particle velocity hits speeds over 17m/s (as shown in your design). The reason I'm asking is because I'm currently working on a kick speaker design where I tried to implement this and got a peak particle velocity over 25m/s. Now I'm not really sure whether I should change the design so the particle velocity is lower than 17m/s or whether I should keep this in order to have some air exchange. (The output of the port does not really contribute much to the overall spl output, almost everything comes from the horn itself) Thanks in advance

I have a question - if you were to have stacked your horn instead of it being two opposing horns, would you have been required to separate the two horns vertically? In other words, could the horn dimensions simply double because two drivers would be used?

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.

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

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!

Scott: Is there an "ideal driver" similar to the ideal op-amp in electronics? I suggest that using an ideal driver would separate analysis to represent the horn apart from the driver.

@speakerscott 3 ай бұрын

Not really, there's too much interaction between the two in practice. You can on a op-amp because for many circuits the ideal behavior is close enough to the built behavior you can ignore the non-ideal bits. That's never really the case in a horn.

@@mr1enrollment No. The acoustical impedances are such that you can have very different frequency responses from the combined system...the horn isn't independently modifying the driver response, there is an interaction between horn, back chamber and driver.

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.

@datdudeinred Жыл бұрын

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)
