I would hate to have you mess up a good speaker, but I wonder if spray on truck bed liner would work. I enjoy watching you work on your projects. You have made me want to try to save an old set of speakers.
Thanks Daniel, felt is a good idea. Years ago I had access to scraps of industrial grade felt that were black and at least 1/8” thick. I used that on the front baffles of several speaker projects and it seemed to clean up the sound, I'm sure it would help on the inside as well.
Great video! Refreshing to see an original format UA-cam video. I am dealing with a dual 10 ported box that could win a resonance contest. Considering using this product to solve that issue. Did not see the end results of the spray on boom mat listed. Other than the smell, were u pleased with the results? Did the spray on reduce the resonance to an acceptable level? Thank You
Thank you for watching and the questions about boom mat. The results from the spray are negligible, but I would recommend trying the sound deadener pads, (I use Siless but they're all similar). Additionally I wonder if the port(s) aren't tuned for the dual drivers? Just guessing... i know ports can make some terrible noise and if they're not doing what they're intended to the noise might be coming through the front of those woofers or the port. Blocking the port would be the easiest way to tell. If you have a way to measure frequencies you can run a sweep to see if the cabinet is resonating, (it'll likely be a bump in the 200 to 500 Hz range - typically where MDF rattles on the low end and then again higher up near 2000 - 3500 Hz where it will get really loud if the woofers aren't low passed.
Thanks for watching and the question! Regarding the Boom Mat, it was good for making the inside of the cabinet black inside so when I looked through the port it wasn't as ugly. It may have helped seal up the box if there were any air gaps... Other than that it was a waste of time and money. It stinks so bad while it's off gassing, it took weeks outside and in the garage to air out before I could continue building them.
Hi Todd, I was considering this product for an audio project as well. I was hoping it would work as a sound descending coating on a turntable platter/plinth. Would you recommend?
Thanks for watching and I apologize it took me so long to respond. That's an interesting idea for a turntable platter. I'm not sure that it would help, but it might. It does smell really strong though. I wouldn't want it touching the vinyl record either, so it would need to be on the back side of the platter. Possibly something easier and more effective would be the anti vibration pads for the 4 feet, and a rock solid surface that's not affected by vibrations. I remember trying to DJ and play music loud with turntables... All I can say is, thank goodness for digital. It doesn't sound the same, but it's better than skipping.
Interesting product Todd I will have to give it a try. Your affiliate link is not working so well does not take me to the product so not sure if you would get credit if I buy any.
Unfortunately any construction material for speaker cabinets has a point of naturally occurring resonance. For example the 1/2" thick flake board these were made of resonates at roughly 200 to 400 Hz, and again upwards of 2500 to 3000 Hz if I recall correctly. What that means is there will be "music" playing from the speaker cabinets unless dampened to reduce the SPL. Even just bringing it down to 10 or 20 Db below source playback volume level makes a huge difference in terms of clarity and transient response of the music and vocals that reproduce sound in those regions.
Cool vid! Always learn something watching the content.
Thank you Brent!

I bet those old speakers would sound great with some upgrades.
Thanks Christopher, that's one of the nicest comments I've received and if the videos have provided some inspiration that's a win win.
Strips of 1" X 3/16" door felt works great for covering the braces and reducing reflections from the braces

Try using cork for cabinet lining, you’ll be amazed by the results. buy in sheets and cut to size.
Thanks Angelo! Definitely something worth trying. I did some quick research on cork and it seems to be an excellent choice for sound dampening.
Great video!

You don’t need sound deadening mats on wood. Wood is a superior sound deadening.
