This a pair of good condition Seas Lotus Reference 6.5" 4ohm midbass units. I used this pair in a 2 way system for my car and the sound was phenomenal.  It uses the same magnesium cone midrange as the Seas Excel line and gives you some of the best midrange available .The midbass is also very punchy and defined. The cone and surround are in excellent condition with no tears or punctures. Thanks for looking.
