About This Listing

used, been around the block a few times, had its dustcap replaced, but still rocks!  

Eminence LA12850 12" Professional Woofer 8 Ohm

Providing clean low mids and tight punchy bass, Eminence's 800 watt 12” LA12850 woofer features a shallow, cast aluminum frame and a Thiele-Small parameter set that allows it to work in ultra-compact vented systems.

Very tight packaging for line arrays, or other systems where overall depth is limited, is enabled by a mounting depth that measures less than 5". The LA12850’s super-stiff paper cone is driven by a 4" voice coil and a powerful vented ceramic motor assembly.
