A very worthwhile and enjoyable series of talks . I would be interested in further information on what determines box size and shape . With thanks Leigh .
Excellent review of why speaker's have issues and what issues show up in measurement's. I am wondering though if you've found any correlation in phase response curves to breakup areas .
Danny, can you explain what parameter I would look for to determine whether a driver is used for hifi use, pro sound use (as in on stage), or car audio use? I'm not sure if it would be in T/S parameters or something else.
Thank you or your advices and your technical overall knowledge that you pass. Please is it dificult for you when talking over a graph, to show what are you talking about with the mouse cursor viewable- something like voice over in other dimension- prefearbly with yellow circle around for easy view. Thanks a lot Leon.
This is the 300ms 20Hz-20kHz waterfall on my Linaeum LT1000 speakers - initial output is about 85dB and the floor is at 35dB: photos.google.com/photo/AF1QipPp-0vzUtRcpV6DrIVqnrpyr-nk-xfGOYdfZ663 As I watched your video, I realized that the spectral decay graphs you show are a different thing than the waterfall I got in REW? Unless mine in is in microseconds and yours is in milliseconds?
@@dannyrichie9743 Thanks for your reply - I was attempting to find out more about what the waterfall graph in REW is showing, and I am still not sure. I redid the EQ filters and now have the response smoother, and pretty close to a room curve.
@@dannyrichie9743 Okay, that makes sense. I am now wondering if REW can do a cumulative spectral decay measurement, or what program that I can use, can do this?

I find myself saying “one k-hurt” now after binging on Danny’s videos
Thanks, I needed this to make this stuff sink in properly. Please keep up these helpful tutorials!
Fantastic vid, Danny. Thanks 🔊🎶😊
Thank you!! I love your videos!! Yesterday I bought some driver from you I hope they will be good as I expect!!
Thank you for your videos !!!! I have learned so much !!!! You are my mentor :)
Wow, dude! Amazing content. Thank you very much.
Thanks for this video. It explains a lot about the graphs.

What a great presentation! Thanks.

I thank you so much, for all you do.. learning a lot...
nice content

Do you have any advice on type of speaker wire gauge, coating slid vs stranded etc.
For our internal wire we use a four 9's pure Copper in polyethylene, and it is solid core.
So how do you make a speaker have a good spectrial decay?
NO break up modes or stored energy issues. Lighter weight moving masses really helps and limiting exertion.
@@dannyrichie9743 So film, foil or multiple dynamic drivers sharing the load. The later is what I did. Thanks.

300ms is a long time. You are also looking at the decay rates of your room. I am showing the decay rates of the speakers only. Big difference.
@@dannyrichie9743 Okay, understood - I will see if I can get a gated / pulse measurement, in REW.
@@dannyrichie9743 Thanks for your reply - I was attempting to find out more about what the waterfall graph in REW is showing, and I am still not sure. I redid the EQ filters and now have the response smoother, and pretty close to a room curve.
@@NeilBlanchard It is showing how long it takes for the room reflections to die down. Unfortunately it will all change with SPL.

My wife gets upset with the low frequency of my responses to her, while she talks to me.
You’ve been wearing the same shirt for a week...
Lol. He probably recorded all the videos in the same sitting
Last night I recorded two video's again. Maybe I should swap shirts between shoots.
