I am about to re-do the round "snowman" pods I have on my front door sail panels as Ive blown the 2" midrange on one side and have always wanted to try 3.5s in the same location. Im using 3.8" styro balls wrapped in foil then the fleece. The first round was fine with one layer of fleece and the resin, and I realize it would probably be fine again with one layer but the option exists now and it wont later. I was thinking of quickly saturating the first layer with the resin, wrapping it with another layer of fleece, then hitting that second layer with resin too. Drivers are Dayton ND-91s and im putting 40 watts to them probably from around 250-300hz to the tweeter crossover at 3k. Two layers would be overkill, right?
