Hi everybody, I´m put my hands in a hammer dynamics super12 FR kit, the novo the sound is great, very clear and detailed.
my question is, on the web all agreed that the best damping solution is asphalt layers cover by bubble wrap and a deflex layer behind the driver. unfortunately beside the wrap I can not find the rest. I just found a Dynamat extreme sheet (for car isolation), can i use it? (i believe is the same use of the delex and asfalt), my concern is to not "eat the bass" instead of order it.
any experience? thoughts?
thanks in advance

I presume that damping the vibration of the enclosure is your aim. Dynamat Xtreme is a thin, super sticky butyl rubber bonded to an aluminum alloy skin. It is used to reduce the vibration of metal car panels. To effectively damp the vibrations of a wooden enclosure, it would be best applied in layers.
Deflex panels are thicker (about 10mm) and sculpted to scatter reflections. Trouble is, it appears they are no longer manufactured.
Carpet tiles have thick heavy and lossy backing very suitable for gluing inside cabinets and are economical.

All agree is not the case. Adding any sort of damping iike deflex or asphalt if building enclosures like ours would be counterproductive. It adds mass without adding stiffness. We work to raise any potential box resonances and to increase their Q as high as possible so that, with music, they are almost impossible to excite, effectively making a box that does not resonante when used to play music.
Our experience with the Hammer DYnaamics was not like yours. A lot of work was done to try to make them sound decent. In the end they went off to someone else at a considerable loss and the boxes went up in the big bonfire.
I do hope you enjoy yours thou :^)

Thank you very much, yes deflex was my aim but there is not available in Chile, even worst due the covid.... I only have access to this dynamat. probably I will try it in layers as you propouse
I will!!! thanks for the best wishes... 🙂 I´m just starting in the DiY, and probably half deaf (no very demanding at this point) so I will keeping tryiong to get the best I can of this hammers.... if I understood you correctly it does not matter if I use carpet or this layer?... (knowing that the speaker will sound bad per se)
