i really think you need to realize that the 10"l7 2005 = the 10" l5 2006. the 06 l5 has the same specs for the most part as the 05 l6 . that is what kicker did this year. improved the l7 and moved the tech from the l 7 to the l 5 for this year.
why are u getting a prefab in the first place? if u do a search on the forum, it is best to either let an experienced builder (jordan_tyler) to build your enclosure or just build it yourself. You will get wayyy better results than using a prefabricated POS.
