What to know before buying

Listing details to confirm

The listing gives 28 Hz for frequency response and identifies a 20 cm (8”) cone woofer, but its connectivity details conflict: it describes the connection as Coax while also listing general wired connection elsewhere, and the technical table labels Coax as a wireless connection. Confirm the intended input and cable requirements before purchase. The title says 8-inch driver, consistent with the detailed driver information.
