www.edesignaudio.com. I have used to have 2 of their e12k's, sealed...and they sounded fantastic. I got metered at 144.7DB w/ the 2 12's, and a JL1000/1 amp. If your looking for some good SQL, then you need to check into their products. I think you can pick up a pair of 12's, and a JBL 600.1 and be doing alright

You CANNOT go wrong w/ their subs. Hope that helped some. Peace.
