I bought this sub and box a few years ago. But it was only used for about a month. Since then its been sitting in my basement. It still looks and sounds as good as the day I purchased it. It's has dual 4ohm voice coils and can handle 800 watts. It's currently wired with heavy gauge monster cable in a 2ohm configuration. The model number is RFP3210. The speaker alone retailed for $220 new. I think I paid around $50 for the box. But I'm selling it all together for $100.
