What to know before buying

Listing details to confirm

The listing combines conflicting product descriptions: TX412B details specify a 12-inch, 600W speaker with two channels, dimensions of 38.1 x 34.3 x 60.2 centimetres and a 13.3 kg weight, while other sections describe a Busker with a different cabinet size, weight, 3-channel mixer, battery-runtime claims of up to 20 or 24 hours and Bluetooth 5.3. Confirm the selected TX412B specifications and applicable battery runtime before buying. The stated 20 KHz frequency response and 100 ohm impedance are also unusual or incomplete as presented, so treat them as unconfirmed listing details.
