Has anyone already upgraded the L300 cross over network model N333? If there is a member that does this and charges for his/her services i would like to speak to that person about getting my 2 n333 crossovers refurbished/rebuilt/upgraded/updated to replace any worn out parts and make the speaker produce the best sound it can.
thank you. contact information : [email protected] or 425-513-9445 ask for Richard
