    That particular exciter would be more then sufficient.....The problem with that small of a panel size is that it wont have much bass response....Panels need to be at least 16inchs minimum before any real bass frequencies can be heard and more preferable in the 2ft. size.

    The only down fall to full range DML panels is that it needs to be large enough to produce the lower end frequencies......The only other way is to use very small panels with a separate sub woofer to fill in the low end.

    Hi all, complete newbie here, I've got a couple of DAEX32EP-4 thrusters coming that I want to make into a pair of bookshelf style speakers, would a 12" X 12" panel be sufficient for an exciter like this?

    Unb ... mrpolystyrene.co.uk got me to page that has no inputs. No luck with ebay, either. Assume is ID10T error. Will you help once more?

    Higher grades of EPS are 3 and 4 lb density. Ads are not showing. Can you supply guide to the better stuff?

    It needs to be the higher harder density/grade EPS....The more common standard readily available EPS is used for insulation and or packing as these are low to medium grades which can sound muddy due to it being to soft....The higher grades are not as common and harder to find in your local hard ware stores.....I order mine off of ebay.

    Good, I have some EPS that doesn't look flakey.
    I'll try it.

    I do have some small bamboo ones to try. Ordering balsa as well. I plan on trying many and larger ones, too. To be proven, but sure larger panels even cutoff on bottom end could exhibit better upper bass response.
    No, they are EPS which is Expanded Polystyrene.....EPS seems to have warmer tones then XPS.

    Regarding fine air particulates -- in general -- this DIY filter is a good option. https://www.youtube.com/watch?v=kH5APw_SLUU

    I have a Foobot indoor air quality sensor plus the Dylos fine particle sensor. That cheap box fan knocks down larger particles fast and the smaller ones over time (apprx 24 hours.) However, I tape on a 20x20x4 furnace filter instead of a one inch. Clean air will keep your heart ticking.

    My Bastat panels have great mid range frequencies and they are 12inchs width X 16inchs height X 1/2inch thick. You can try that size to see if it sounds to your liking.
