1 pair high end TDL Studio 0.5 transmission line speakers in black. The speakers can be used in bi-wiring and function properly. When set up correctly, they offer a super bass and a differentiated sound. See post at HomeTheaterReview. Except for damage to a rear box and a missing TDL logo, the speakers are in good condition. The lower base was later added. Will be well packed for shipping.
