I bought this pair of 18"s 4 years ago used . I have no way to reach the seller to get specifics of them . Here are some things I have to help figure it out . They are testing at 2ohm at each of the 2 coils , they weigh 66.9 lbs , the cone measures 6 " , magnet is 9" wide and 5.5" tall . Would appreciate any help to identify this sub . Thank you in advance!
