Overview
The Bestisan SW65C pairs a 6.5-inch driver with a 400W rating in a floor-standing subwoofer, connecting via Aux or RCA, in black. It's a wired bass add-on rather than a wireless unit.
The speaker type field lists bookshelf and woofer alongside subwoofer, which likely reflects shared category tagging rather than three separate driver types in one enclosure. The confirmed core spec is the 6.5-inch driver working as a subwoofer, fed through Aux or RCA inputs.
- 6.5-inch driver
- 400W power rating

Who it's for
Suits a buyer adding dedicated bass to an existing 2-channel or home theater setup through a wired Aux or RCA connection. Not for someone specifically needing a wireless subwoofer link.
Pros and cons
