Friends,
The weekend is back !! so I am thinking of finishing off with my sub build over the week end, by damping and stuffing he polly fill/ Glass wool and mount the Amp and driver.
I had contacted Denny to know :
1) What all panels we need to apply the damping sheets on - On which he replied that we can apply the damping sheets on all the panels obviously on the internal sides just that we dont need to apply these sheets on the braces
2) What kind of stuffing we should used for the selaed sub, should it be polly fill or Galss wool - He said either is fine
3) How much of stuffing by pollyfill or Glasswool needs to be done for the sealed enclosure - On this he responded saying that we can have a thick layer of around 6" infront of the amp.
He also provided me with the below link of another forum, which has pictures uploaded by one of the DIYer, of how he has damped and stuffed the sealed sub enclosure with polly fill. ( however he had kept used seperate box for amp so that was one big difference)
The link is here -

Now I urgently need some suggestions for followings to be able to complete my sub build this weekend with the help of fellow members here:
1) I went to see the Bitumen sheets in the market today, and they seemd to be little stiff / hard atlest they were not soft.. so what is the best adhesive that we can use to stick the bitumen sheets inside the enclosure? - one FM had suggested Fevi Bond to me, however after looking at the sheet it seems hard that fevibond will be able to hold the sheet closer to panles for long.. please can you all share your experiance and advise if Fevicol or anyother adhesive will be better ?
2) For stuffing the polly fill / Glass wool infront of the amp as suggested by Denny, It actually means putting a thick layer on top of the plate amp on the inner side, can there any problem as the Polly fill/ Glass wool will be in contact of the amp? can it damage the amp?
3) Is it advisible to just put in loose polly fill/ glass wool to make the 6" layer or should it the whole bunch of material be tied up with help of a thin thread or something so the the material doesnt spread inside the enclosure while playing the sub?
4) While applying the bitumen sheet on the insdie of the panel on which drive mounts and on the panel where amp mounts, is it ok to apply the bitumen sheet too close to Amp / Driver ? or should we keep some distance? do these equipments get too hot? and can bitumen melt if these equipments get hot?
Please can some experianced folks help me with above based on their knowledge and experiance?
Thank you very much for your help in advance and have a very happy week end ahead !!
Regards,
