NIK.......I have never conciderd any WESTLAKE system a toy. None not any of them. although I do have a favorite WESTLAKE the SM-1 You have to remember some of the components are JBL. But the tolerence are even tighter. Your K2 is also of this caliber & like the WESTLAKE. can be tweeked to even a high standered. Take this in small steps. Extend the top end first. take your time and get used to it before the next step.
