you won't upset me
ss subs are underrated (at least in power handling) . i'm planning on using one with a 500w amp.
sq would be better. the tc2+ motor (used in the rl-i series) has a very low distorsion factor. i've never seen a bl vs x graph for the daytons. you can find those graphs for the tc2+ motor.
my guess is that if you like the rs or titanic series from dayton, you don't have to worry. :-/
wo32 is said to be the best audiophile sub. i'm not sure a wo would outperfom one when using the same subs. the wo isn't as picky as the wo32 when talking about driver selection.
i'm not sure you will hear too much of a diffrence between 85.5db and 87db. :-/
it's superior in excursion. this also plays a role in lf extension
