A better use of Dynamat
I have a pair of MachOne speakers, not good. So, I lined them with peel and stick aluminum face rubber sheets left over from another project. No other changes were made. The inside of the box must be primed or it won't stick.
It didn't fix what comes out the front of the speakers but it did stop the cabinet from broadcasting junk around the room that I was not aware of.
So yes, good idea.
Remember the Mach's don't have much capability. I read up on your BIC's after your recommendation on another thread. What you got going on there is a whole different thunder box than the Mach. Might need a more aggressive approach. But something. Yes it was peel and seal
You are mistaken. Do a little research. You are confusing cabinet damping with cabinet stuffing. And please quit with the all caps yelling.Dang, still kicking around your BS "theory" of "why not, it can't hurt."
Why spend money on BS stuff like that - just buy better speakers to begin with!
Dynamat is one of the more expensive materials going. It has a function, its used by Car Audio folks for deadening METAL area - like inside door panels, under the carpets - generally to cut down excess road noise so you can hear your tunes better.to tone down rattles and ringing in metal areas.
That has NOTHING TO DO with deadening a WOODEN BOX! That kind of wood does not ring!
Use roofing pitch or the sticky sheet another member mentioned.
If you want the box to act "larger", or to play lower, add some polyfill in stages, experiment, until you get the results you desire.
I just used a comparable material called QPads to deaden the metal ALTEC 811 Horns in my Heath AS101 speakers - to stop any potential ringing!
($36 shipped from Amazon for a box of 6 sheets of 12" x 12" material - its a tarry material with LEAD mpregnated - MUCH cheaper than Dynamat.
Insulting people because they are being frugal/sensible is outrageous!

You are wrong - Yelling or shouting is when you leave the caps on for a whole post..And please quit with the all caps yelling.

Despite it's origin, it is also widely used to deaden speaker cabinets just as Black Hole 5, Whispermat, etc.are also commonly used. I probably wouldn't choose dynamat but lots of people do.She is not mistaken. Dynamat was made to dampen metal surfaces, not MDF, chip board, plywood or wood.
Fortunately it reduces vibration on any surface you stick it on, regardless of it's intended use. Yes, even wood product.
So after the debate I hope we're past the point of understanding that Dynamat products can and do dampen surfaces for acoustic purposes using bitumen as their main ingredient.
Maybe the OP can conduct the said experiment now and report back?
Try to keep this thread on topic - Original poster wants to replace his rockwool/polyfill with dynamat in his Yamaha 3ways ...
Hardly, These products are widely used by people rather than adding cabinet bracing or with cabinet bracing. People also use ceiling tiles, floor tiles, Deflex sheets-none of which were designed for speakers but work well in that application.I'm really not sure why you still don't understand it's the wrong product for what the OP wanted to use it for.
