Yes, that's the way it is starting to look. So...options? Not able to find the Peerless 12" PR in stock anywhere (Madisound, PE). Could I go with 2 of the 10" PR's? My budget getting squeezed with that option and I fear that correct tuning may be out of the range of my limited abilities. Actually may be better off looking for a different driver that is more suited to a ported box. Thank you for all the responses.
