Hey guys well i know that i am new and all that good stuff but i have to say that i do not have very many refs the only person that i do a lot of business on the net with is evan from havoc audio

but as the title says i have 2 18" RD Alpha V.2's i am looking for 250 plus shipping and the paypal fees if thats how you would like to play. These woofers are 10/10 functionality and about an 8/10 cosmetic there are a few scratches on the basket and motor other than that they are great.

if i need to post pics i will and i have some with my names on it but the date is old on those.
