The Gator Cases Rolling Speaker Bag for Small Format 12" Speakers is a carrying case designed to fit the Mackie Thump TH-12A, QSC K12, and similar 12" (30.5 cm) loudspeakers. The bag's dual-zipper design allows easy load-in of the speaker, while the bottom has structured foam to cradle and protect it. Rugged nylon construction with 0.4" (1.0 cm) side foam ensures durability and extra protection against impact. The rugged and retractable pull-out handle and 6-wheel assembly make the bag and the speaker inside it easy to transport. There are also two accessory pockets for storing cables or other small items and the security of a limited lifetime warranty.
