Which subwoofer?

@kenrus , you wont, its the quality of the base rather than 2hz either way that matters most.

How about looking at used ML Descent i’s , I recall a number hitting the classifieds when the newer models came on line.

I find myself in agreement with @jwillox . I moved from a pair of ML Descent i sub’s sporting the optional crossover cards with my ML CLX Anniversaries to a more centrally positioned single ML Balance Force 212 and preferred the ease with which a single source base extension integrated with the main speakers and room.

That said for 80% of my music predictions I switched the subs/s off as I prefered the more natural midrange of the CLX’s with their own integrated ESL base panels which measured down to a solid 46Hz -4db  in my room.
