    I just found the answer. Thanks for your help, I really appreciate it.

    I understand that but I thought there was a formula using 5ths such as 2/5, 3/5, etc.

    You can place them any where that sounds good to you as its all personal preference. Some prefer dab smack in the middle of the panel while others prefer slightly off center while others prefer angles or corners, again its personal preference.

    Place the exciter on the panel and move it around until you find the spot that sounds best to you then mark it and mirror the other panel.

    Where exactly do I place the exciter on the panel?

    What measurements?

    I just made panels measureing 12" X 24". Please help this math handicapped one with the measurements for exciter placement.

    Yes....I have used both sides with glue before but just as long as the surface contact area is smooth/clean the sticky adhesive works really well.

    Do you utilize the adhesive on that side and use pva on the non-adhesive side?

    I dont think so but I am not totally sure. The Frost King foam I use only has one side that has the sticky adhesive.

    Do you know if frost king makes a foam weather stripping in the size you mentioned without adhesive on either side. Was thinking it would be easier to install and for the pva glue to adhere to the foam weather stripping alone.

    PVA wood glue like Tightbond or Elmers

    Understood and makes sense. What have you found is best to use for gluing the foam to frame and panel?

    The compression does not need to be that high it just has to fit smug enough so that the panel does not fall out of the frame when placed upside down. Plus you have to glue both ends of the foam one to the panel and the other side to the frame.

    Ok, understood. The foam pressed into the gap is the only force keeping the panel centered within the frame and must have enough force to prevent the panel from eventually relocating itself in or out of center in relation to the foam surround due to vibration.

    So, with that said, with the 3/16" foam thickness you use for your surround, how much less is the gap you utilize (less than 3/16") so I can get an idea of how much the foam will compress to ensure I have enough holding force to prevent the panel from moving in or out of the frame due to normal vibration? Would a 1/8" gap between frame and EPS panel allow enough compression when inserting the 3/16" foam in the gap?

    Found a better pic. This new version of Bertagni speakers use the foam surround all around the sides of the panel the same way I do it.
