Anyone here have experience with running N series and S series JBL speakers in the same system? Are they fairly well matched? I have a pair of ND310's, and a big room (20'x30') and don't have a lot of confidence that the smaller N series (N26 specifically) can keep up with the ND310's. I got an N-center, and it certainly couldn't keep up with the ND310s, they made it sound flat and weak by comparison. So, am I making a mistake if I buy four s26IIs as my four surround speakers? Should I stick with the N26's that match my mains even though I am not sure they will be up to the job? Thanks in advance for any help you can give me!
