Double 18" DIY Horn Demo
Quick demo of the double 18" horn....had to be quick...I was going to get the cops called....
1. Couple of notes...I had the action cam lightly gaffed to the brace...during the demo it broke free and started to rotate...I couldn't have planned it better.
2. I only had one of two horns active, so balance is a tad bright with the tops, but the bass was so violent in my garage and house I figured I'd get the cops called pretty quick if I had both playing. Gets a little distorted at the end, but that's mic overloading...not the horn.

Quick note: In the video I say "something I've never seen before" regarding the bad solder joint....well...I've seen lots of them...but not one quite like this where the lead is so long and the board was deigned for multiple bulb types. So....there you go.

The best tutorial for rew , thanks
Any chance you could demo your MEH?
Yes with these subs and stand-alone
Any chance you could demo your MEH?
Scott, it is time for the Part 2! :)
"Quieter than atoms moving" lol
Is there any way once the live version is done you can go back and edit out all the stuff at the front end? Great stuff otherwise.
hi scott this emanuel form hawaii are yoy doing audio still
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.
It's march 26 of 2024, so I am 3 years late. But what a fantastic class! One of the best videos on the theme I have seen, thank you so much for sharing the knowledge. Hope can someday continue doing the videos. Greetings from Bogota, Colombia.
I enjoyed the passive crossover design info and was very interested in obtaining 2 Faital horns but none are available. Also I can't read the crossover specs as listed on design sheet--blurry.
Do you have Instagram too
Hello there! I would like to ask a question regarding to manipulating the tweeter SPL level. I don't want to use L-pad, and I saw different design choices on the net. They use only 1 resistor in series with the tweeter, and sometimes the resistor is before the capacitor and coil, sometimes it is after them. I noticed that before the capacitor and coil it pushes down the freq response as a whole without "bending" it in any shape or form, but if it is after the capacitor and coil, then it leaves the "declining" part more or less in place, and it "pushes" down the top horizontal part. Which one would you recommend? Is there a huge disadvantage for any of these solutions?
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)
Must have the coffee and water. Passive crossovers do waste power in the bass section, how much powere depends on the design and parts choice.
Man you are truly expert for this but you are boring man with bad jokes,not funny and seems to me that your wife if you have it cheating you with some funnyer man.
just try japanese drum fire music
this is so clean, i love it
I really enjoyed the video. It was extremely educational and you made it fun.
The manic laughter at 54:00...
Hey great video, I'm thinking of reducing the horn throat area on our scoops, thus increasing the compression ratio. Do you know how to determine what the horn throat area and compression ratio should be? Thank you sir 😊
Sorry couldn't get into this. I wish to learn more about REW. IF there's anything useful on here please edit it down and repost it. Cheers.
I hope part 2 is still coming. Great video
Hi Scott. I noticed you haven't posted for a few. Do you do crossover design for hire? I would be interested in hiring you for a design.
that is not the transformer that my 3100 has lol. Not at all the same.
Thanks Scott :) btw, what’s the low pass on the sub here? Cheers
This was great, along with your other streams on the channel. Are there more somewhere else to watch?
very informative, thanks.
Hello. With regards to the impulse setting of the IR window, can you please tell me, due to the sweep total time, does the IR take snapshots of the room every time the IR window time is spent? I'm a little confused with how the rest of the reflections are removed and not just the first reflection. Thank you. I hope you find the time to respond.
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!
I finally understand windowing in REW, thank you!
how software?
Its suresh From india, I was Planning to Build an HiFi Stereo System Using Ur DCX464 and ME464 ..,I was Very much impressed with ur Desighn and Spec of the DCX... I want u to Suggest me The Best Combo of Drivers To Build a Stereo System Using DCX464,also Suggest me the Best Desighn for An Enclosure too for an Stereo not an PA .Kindly do the Needfull.. Thanks in Advance.
You think its good enough to be used for hifi?
Really informative and reality based cheers.
Seriously, Hire You. Why would I learn these softwares, just to make two different pair of cabinets for my personal use. Is $200.00 insulting to you? I have "blueprints" but sure they need correction. I'm far from in a rush (or can be). Sincerely, Tom
HAHAHA THE GIGGLING AT 53:27 ... REMINDS ME OF THE FIRST TIME I PLAYED MY FIRST SUB BOX

I've never owned SAE gear... despite salivating over the aesthetics thru the 70's and 80's. I recall big full system rack with complements of all things SAE.
Drink next to a laptop never a good idea =) I like you setup there!
Scott, do you plan on doing a follow up video on this?
Can you do a video on series tuned 6th orders? Mainly for caraudio purposuse?
Idk what all the other people are hearing here in this video saying "very helpful, good video" bc this has got to be the worst fkng video in UA-cam history. Talked for a damn half hour and didn't say a damn thing. I'm sitting here with my laptop, REW on my screen, and didn't get a single piece of information to get me started.
I'm deeply thankful
Tweeters B&C DE35?
Nice video and explanation, Thank you
Man this is great. You having less than 1k subscribers is a crime against humanity
SBX3 build would be nice to see
Scott what is end correction? Do I need to add this length when building?
I have learned a lot from your watching your videos, they are very informative presented in a manner that a novice like me can understand. But please try and reduce the times you say "um" it is very distracting!
hugh to Eienstein; "Yeah you're good but, I can't focus due to your hairdo."
hello, thank you for this ! Did somebody put this build into AJHorn 7? what are the differences if any?
