    Loved the 8” mini earthquake passive radiator build!  If I was to upgrade to a 10” sub, I assume using 10” radiators is correct, but what size box would I use?  What volume, and is going to 3/4” material and/or filler needed?  I m a real newbie.  Just got two jbl 3310s at auction for 46$ for my shop and wanted to add a sub kinda in the middle.  The mini 8 might be a little small?  This is going with a fosi  bt30 class d amp.   Thx so much!

    Well, the tang sub was about 90$.  Hoping to get a bit lower.  Any suggestions for  a driver to fit in the same box but budget friendly?
