The Eminence Basslite SC10 is a 10" speaker optimized specifically for sealed bass cabinets. The ultra-light weight will take the weight out, but leave the performance in. Featuring a 4 oz. neodymium magnet and 2 inch voice coil, this 10 inch speaker is available in 16 and 32 ohms for your 4x10 or 8x10 rig."We wanted to design something that was designed specifically for sealed 4x10 and 8x10 cabinets." said Anthony Lucas, Design Engineer at Eminence. "We're offering them in 16 ohm and 32 ohm options as we envision them for multi-speaker configurations. The 16 ohm model has a program power rating of 300 watts, and the 32 ohm is rated at 200 watts."
