Finally, 20-39 arrived this morning thanks to the SVS staffs I currently don't have SPL meter or AVIA dvd. I definately get both very soon though. In SVS manual, I should set it to no higher than "-5 dB" and what should I set with the rest of my other speakers? I currently set all at SMALL and output level at max. I have a small Receiver (yammy HTR-5450) JBL n38ii as mains small yammy center and surrounds Please give me some aprox numbers (or which one should set higher, which one should lower...) I'll do it tomorrow morning, very exciting!!!
