I like sealed alignments. I'm able to shape the response with little regard to the tune. Enclosure volume can assist in limiting over excursion. Trade off time... You better have alot of stroke in that driver, and alot of power, especially if you plan on extending down into single digits.... And speaking of single digits, it wont be done with one driver unless you bolt it to the side of your head Lol. Multiples are a must to create the feel of limitless bass and multiples also smooth out room modes at the LP.....and to get the SPL high enough at the LP.
So, with that said i will go back to watching Rush Time Machine Tour on BR......peace KG
.....errr and my six sealed subs bahahaha
