I was thinking of picking up a couple Sa 10 d2 subs from sundowns yard sale, anyone know the quality of the subs from the yard sale? I know they are b-stock and subs that didn't pass qc, and some are old stock but last time I bought yard sale subs they were from Skar, two were flawless, and the third was pretty bad. Also what do you think I could sell a Re Se 10 d2 for? It's the older version. Any opinions would be great. Thanks.
