Okay here is the thing, whenever I use autoEQ, I found the bass is lacking and sound bit hollow, so I manually adjust the EQ setting in the receiver, now I found the sound too bright for my room. My question is there are adjustable DB level for various freq. for each speaker in the receiver. what method I can use to EQ the speaker manualy, SPL meter and do a freq sweep from 60hz-20khz? also do I need to lower the higher freq range(10khz+) in the receiver to lower the brighest that I heard in the speakers due to my room?
