I would like to replace my current subs for some that have better Spl.My problem is I cant find one that is designed for smaller enclosures.I would prefer to have two subs but would consider running just one.I have always run dual subs so I dont know the capabilities of a single sub setup.I mentioned in another post that I liked the Elemental K series but the size of box I would need for 2 of them is really more than I want to use.How would a single K sound in the appriate size box?.....ANY suggestions are welcome.
