the yamaha can handle the 4 ohm load. you can change the settings on it for the 4,6 or 8ohms speakers. the orbs are set up in the mod 2 configuration which means there are 2 speakers wired together for each side which make them a 4ohms load also.i have been fooling around with all the adjustments for awhile and the orb guys have been great but i just feel im missing something and it could be because i had cerwin vegas for the last 16 years or so. and even though they arent close to to the quality sound im getting from the orbs i guess im used to getting that big sound punch.i have fooled around with the crossover settings, the bass on the sub along with the bass and treble on the receiver. maybe its just me but im looking for what i had but just a lot cleaner sound thus the search for towers
