Hey guys, thanks for your response to my thread about 2 10's ported vs 2 15's sealed. All of you gave a recommendation to go with 1 15 ported. I took your advice and it worked out nicely. I went with a 15 inch RE Audio 15 SX. I got custom made box today at 3.8 cubes tuned at 33hz and it sounds nice. At frist I couldn't hear a difference but once I went out adjusted my gains and played with the system, the deepness of the 15 is nice.
