<font color='#000000'>Mac Guy,
I whole heartedly feel that the Studio Series from JBL is the better. I felt that the Northridge Series was too harsh, and distorted easily at high volumes. If wou look to put together a nice JBL system, buy the a pair of the S38iis for the front L/R, S36iis for the rears, and a S-Centerii, and pending on the size of your room, and buy a sub ,prefebly a 10in.
The only question I have is what receiver are you buying or already own?
