I recently bought myself a Pioneer VSX80TXV receiver and hooked them up my to my old JBL speakers. I ran the automatic speaker detection setup (MCACC) and it classified my speakers as being "small". Since running the MCACC my speakers have been sounding really low. I have to raise the volume nearly to it's max to enjoy a movie. I've since decided to replace my speakers with Klipsch Reference 10 speakers. So far, I've gotten myself the center and front speakers. However, I'm still experiencing the same problem... The MCACC is still classifying my speakers, except for my new front speakers, as "small". What does that actually mean, when a speaker is small? Could this be what is causing the reduction in sound? My receiver outputs at 110Watts, my new speakers run at 75watts continous and 300watts maximum. Does this make a difference? Any thoughts? Thanks in advance!
