ROLLS SX95 Stereo Subwoofer Crossover Filter with 12V Auxiliary Power Outlet - Perfect for Car Audio Systems & Home Theater Setups

9/16/2024 1742 Hours EGMT ...and Wow??, what a difference an actually "NEW" Device makes????! Didn't initially know, nor initially suspect the first one was used (& severely abused) & returned by someone until NOTHING worked, which under suddenly close scrutiny, I saw one of the THICK-Knobs was split down the middle?. BUT Amazon replaced it, & THIS one is NEW, slightly heavier feeling, VERY-sturdy, with white highlight-indicators on the Knobs, and most IMPORTANTLY, it WORKS (during real-Time dynamic changes)??.This ROLLS SX95 Stereo Subwoofer Crossover/Filter, 12V Auxiliary Power Outlet is a physically heavy-weighted device, that supports up to 2 Subwoofers simultaneously---providing the flexibility of "Mono", "Pass-Thru", or "Stereo" hook-up. It comes with its-own Power Supply, & the only downside I've noticed is the skimpy Operational Instructions?. This is a solidly-built device, if it works & lasts as well as it feels, it should last a VERY-long time?!GBJ?
