I am currently using the NSP 5 setup with a 10" powered sub. Am looking into upgrading the front N26's to either N38's or ND310's. Has anyone had any experience using either of these for fronts and how were the results. Am thinking that the N38's might be a closer match. Also has JBL improved the shielding on the NII center. It isn't worth a flip on the old N center. Any replies will be appreciated.
