2 Alpine Type R 10" 4-Ohm Subwoofers + Q-Logic vented case

Two Alpine Type R 10" Dual-Voice-Coil 4-Ohm Subwoofers installed in a Q-Logic vented case (QLH-1.2510DS). Great condition. These subs are amazing, but overkill for what I need. Used for 2 years; never heard any distortion or "farting" through them--never pushed too hard...they sound great! Super clean and punchy. Locals: come listen before you buy. $275 cash or PayPal preferred for both subwoofers + enclosure. Sold as package only and price is firm. Locals can meet in San Francisco or San Jose or somewhere in between, otherwise buyer pays shipping. No cables or amp included.

I'll second that. Alpine is known for their HUs, but their subs and speakers really rock and this is a great deal.
