I like the more in depth approach you are taking. It allows us to experiance more of your expertise and gives us better design and development information. I've built speakers since I was a poor kid. I actually made a box using gypson wall board once with a full range speaker with wizzer cone and it sounded great. That was back in the 1962. Any way, love your channel and projects. Current project has peaked my interest as never built that kind of speaker.

[@sonnoradesign]

Hey Mike! Thanks man! Yup, I get you. We have to go with the flow right? Loong time ago. What you’ve been making now?

[@mikerhodes9198]

Hi, well it has been a bit about 8 years and was the last piece to my home entertainment system. It was my subwoofer. I used a 12 inch Shiva sub and a 6 inch port with an about 4 ft internal tube tuned to 18 hz. Used a 1000w plate amp. The box was about 3f hight by 3ft wide by 3ft deep. A big 6.3 cuft box. The front was made from two pieces of 1 inch MDF board glued together. The front hole is chamfered to allow the speaker to breath. It is baffled so quite a trick fitting in 4 ft of 6 inch pvc tubing. I used 6 inch elbows to make it fit. Don't know if that was the best thing to do but it works. I choose the large 6 inch port to prevent chuffing which worked perfectly. And yes I do get a good 18/19 hz bottom end. I just replaced my Onkyo 717 with the new Sony STR AZ5000ES AV receiver which is a huge improvement. I have a 5.1.2 system. Your channel got my interest which I use as a proxy. I will never build another speaker but does not mean I don't want too. So I watch you. Good tradeoff. Keep up the good work.

@@mikerhodes9198 wow!! That must be a good bass box man. Large though. I wanna start a subwoofer design but more in a lower budget. Thanks for watching and I hope you can go back to making at some point!!

@@sonnoradesign it took me to midnight but I got to be video. I was working on my new speakers they are like 80 lbs no lie MDF with a gallon of flooring adhesive glueing down .75 solid oak and 1.75 sq I finally put the first finish coat on of pure Tung oil cut with mineral spirits it comes out beautiful and I a router the edge and I use gold leaf paint were I router in the edges like a column in a museum or something. They are my masterpieces I silver solder oxygen free copper wires braided big gold plated copper binding posts and I even dipped my inductors in wax it's a little trick

[@sonnoradesign]

Hahah! Sure. No worries Ams. Bass day is coming soon!!

[@linandy1]

Great video, just in time for me too. Ive been researching this for a year now and really want to get started designing. There is just so much information out there, a little bit overwhelming.

[@sonnoradesign]

Hey there! Thanks for watching. Yup. It’s a little too much and sometimes is hard to filter it all up. I’m gonna make more videos on TL soon so you can check how to use the software and build the box. Those are ready and sound amazing.

[@travishall9398]

Way to go! Clicking on video #2 now!!

[@sonnoradesign]

Thanks Travis!!! Let’s do it.

[@PhillioDoede]

Great explanation of how the transmission line works in the real world without getting lost in the minutia of math. Just enough concept and theory to explain how it works vs ported and sealed but dosn't turn in to a lecture. Looking forward to how this turns out and It would great to see you and Neil do a collaboration TL design in the future.

[@sonnoradesign]

Thanks Phillip. I really wanna work more on those TLs.

This video made my head hurt, so many numbers... LOL J/K great video as always brother. Your skill and knowldge continues to blow me away. I'm super excited to see how this build will turn out. Yes, a crossover video would be great, and more speaker / component build videos as well. Keep up the amazing work and keep them coming. Thanks Brother.

[@sonnoradesign]

Whaaaat's up Eddie? Good to see you back here my friend! I'm working on it. New videos coming soon.

[@michaelmccall8719]

Great video explaining the TL design. If anyone wants to pursue this topic more check out Lynn Olson's Ariel TL speaker . He does a great job of explaining how they work and went through 5 designs before he was satisfied which I think is called the Ariel 6e that I ended up building in 2015. 2 Vifa P13WH-00 mids each with a 6ft transmission line with large ports on each side at the bottom and a sealed Scanspeak tweeter. This is a difficult build even for an experienced woodworker and the crossover is not cheap. I think I had well over 1200k in the xover and actually mounted it externally in a matching box behind the speaker. But my gosh- the sound!! I would put it up against speakers costing 6-10 times as much. Many have built it but as far as I know I'm the only one that did a video on the process. Just go to KZbin and punch in Ariel speaker construction.

[@sonnoradesign]

Hey Michael!! Thanks for all the info and hard work!! I’m gonna check that! Those are good drivers, as far as I know, must sound pretty good.

[@fubartotale3389]

I have built the Parts Express Tri Trix TL kit. It is a narrow floorstanding MTM design mass loaded. The design is simple with just one internal baffel?/brace? fitted at an angle to create the T line. It uses two Dayton Audio 5" mid range drivers and a Dayton audio soft dome tweeter. The amount, extension and quality of the bass is surprising for such small drivers. Mids are very good as are the highs for such a modestly priced speaker, although they have gone up $100 (!) or so in the five years since I built mine. The only drawback I can see is the fact that the enclosure must be fairly large to accommodate the T line, so you're probably looking at a floorstander rather than a bookshelf, a deal breaker for some. P.S. I am a recently retired toolmaker and here in America, the tool trades are a United Nations with folks from all over involved. I can't quite place your accent and its bugging me. I look forward to the new design, as I will be finishing up my three way bookshelf project in the next few weeks, (I take my time, its a hobby, not a race)

[@BostonMike68]

He's from LA California 😅 Spanish

[@sonnoradesign]

Hahaha! Boston is kind of right! Born in Brazil, Spanish family! Sure man, those boxes can get pretty big. This MLTL is still a good size bookshelf. Good to know all of that (Tri Trix) I'm excited to hear the result.

[@BostonMike68]

Ok Brazil sorry about that.

[@sonnoradesign]

@@BostonMike68 You were close haha

[@NeilBlanchard]

From what I can tell, that is a variation of a TL - it tapers, and then expands - aka reverse horn.

Heyyy… great video as always… I’m gonna be building a 3 piece set of speakers for my home audio surround using your speaker design with the 3 router bits. It’s a speaker called the rule breaker by Toids DIY…. It’s gonna be slick. I’ll let ya know how it comes out. Thanks again for the great video 👍

Another advantage is the additional bracing that the wave guide provides inside the cabinet. Not forgetting that the phasing of the lower frequencies can be more precise if the guide is doing its job.

[@sonnoradesign]

Right! Thanks my friend!

[@obijuan8466]

linoleum tweeters! LOL!!! I bought a pair of the Radio Shack speakers with those tweeters for my nephew. They were exceptionally smooth and open because of the 360Deg radiation. Too bad they disappeared.

[@sonnoradesign]

Haha! Right? Neil loved it also. I never had the chance to listen to those. Maybe one day I’ll hear Neil’s speaker with the Linoleum one! 😆

[@NeilBlanchard]

They are wonderful tweeters! Linaeum (say lin-AY-um I think?) are unique - they are variable width; in that on lower frequencies, they radiate from a wider area of their curved leaves. As the frequencies go up, they radiate from a narrower and narrower area; approaching a line source. And since they are dipole, they effectively have 360 horizontal dispersion.

[@sonnoradesign]

I'll keep an eye on Ebay for the Linoleum, or Linaeum.. haha

[@NeilBlanchard]

@@sonnoradesign Most of the time, these are available on the LX-55 speakers. The earlier LX-5 speakers use the ET6 tweeter, which is much lower sensitivity. They might be able to be used with a change of the resistor on the tweeter. But I use the ET6A tweeter, which are more common. They are usually $40-60 each; whether they are "raw" tweeters or still attached to the speaker. The woofer surrounds fail, and people sell them as is. Edit: the ET6 tweeter are usually on models with a metal screen on the top of the speaker. The ET6A came on speakers with a cloth covered plastic frame that covers the tweeter, and just comes off. These tweeters use ferrofluid and it can be dried out. I have had one fail, out of about 10 that I have used. Not a high failure rate? But I do now keep a spare on hand, for our friend Justin Case.

AJ-Horn should be a very powerful software for designing any kind of speaker and comes with a big manual and you'll have to invest some time to discover all it's abilities. It costs about 150$.
