My subwoofers offer high pass connectivity and filtering. The manufactures instructions suggests:
If your main amplifier has difficulty driving your main speakers bass to your satisfaction then give the subs high pass circuit a try.
If your main speakers are small and lack bass then give the subs high pass a try.
I love the way my amps drive my speakers low bass. A few of my older LP's simply sound better with the subs off.
Since these subs multi parameter, frequency band auto optimization does so well matching the speakers low frequency presentation, high pass filtering is noticeably wasted. Surprisingly, this decade old twenty minute optimization software quickly and easily solves much of todays hifi subwoofer setup and integration issues.
