Hi Thomas, Great effort educating the newlings! Animations can absolutely help to give insight in what is actually hapening inside a woofer. However in my opinion you may have oversimplified it a bit. In an underhung construction, the voicecoil is actually shorter than the magnetic gap height. The animation showed a voicecoil that is still longer than the magnatic gap, which by definition is overhung. Decreasing the coil length in this example would only mean less Xmax or otherwise losing control sooner rather than later. The diameter of the VC doesn't have anything to do with being overhung or underhung, neither does the amount of magnets determine the height of the magnatic gap. This is determined by the height of the top plate and matching pole piece. (a long voicecoil is heavy and thereforre lowers effiency, a large magnet stack can improve BL to regain some efficiency) Although it may be more technical, if a followup is comming, please include a visual representation of Xmax for both underhung and overhung designs.
Thanks for watching and commenting! Yes, I had to keep things simple for a simple explanation. Like I said there is more to it, and it was a lot to squeeze into 3 minutes... originally was supposed to be 2 minutes but no way I could do that.
@@zarboaudioprojects1430 thanks for your reply. Yes, there is only so much you can do in a limited time. Looking forward to your next projects and videos!
Interesting video. I actually just got a version of Vance Dickasons loudspeaker cook book and was reading about that. Thank you for taking time to make the video.
@zarboaudioprojects1430 I kinda figured you had it . I been designing some really nice speakers without it but it's just going to give me more knowledge.
Explanation is unclear. Underhung voice coil means that the coil is shorter than the front plate. And liinear excursion means that: 1. In case of overhung coil front plate is fully within the range of coil wire. 2. In case of underhung coil the coil itself is completely inside the space between the ends of the front plate.
I simplified things for time, but I did have an underhung driver as a reference for my examples... driver construction. Does differ model to model. Thanks for the comment!
The video is WRONG. Both examples, the over hung voice coil and the 'under hung' voice coil in the drawings are over hung. An over hung voice coil is longer than the magnetic gap. But an under hung voice coil is SHORTER than the magnetic gap. In both drawings the voice coil was longer than the gap.
Thanks for the comment, I think you're maybe looking a bit too close. The magnetic lines are there to give a rough idea of where the 'bulk' of the magnetic force is located.
@@nobelstone9714 Okay, I won't argue. My drawing isn't perfect, I agree -- but it does demonstrate the basic idea.... and it was taken basically from a known 'Underhung' driver. Thanks for the comment.

This was a great video! I absolutely loved it! 💯
Thanks a lot Mr Toid!

Hey we perffer to be called noobs lol jk great video though

This is such a clear, concise explanation. Well done!
Thanks, and thanks for watching!
One of the best info videos ive seen to date. Thank you for this . I learned something new.
Thank you!

I have that book, and I read portions of it just about every year. Great book. Thanks for watching and commenting.

Even though I knew about these terms already, this still gave me some knew insight. Very valuable information put together nicely. Great work!
Thanks! Glad you enjoyed it!
Very nice and clear explained!
Thanks a lot!
Nice, thanks for the great info.
Your welcome, thanks for watching!
Awesome info, thank you
Thanks for watching and commenting!
I liked, I shared, I subscribed, and I commented.
You're funny Justin! Thank you for that.

@@zarboaudioprojects1430 Sorry but the drawing for the under hung coil is over hung

@@zarboaudioprojects1430 But the drawing is incorrect.
You visualizations and explanations are all wrong.
It was a simplification for sure! Thanks for watching.
