Power vs Volume Question
I have two HT systems. Both are powered by an Onkyo receiver. Yes, I know... ;-) Consider me a frugal consumer.
Upstairs, a TX-NR777 (110 watts RMS) runs a bi-amped 5.1 system with Energy C-100 bookshelf speakers, surrounds, and a wired sub. It's fed by a PS3 through HDMI.
Downstairs, a TX-NR505 (75 watts RMS) (Correction TX-NR515, 80 watts) runs a sound bar, surround speakers, and a wired sub, fed by an Xbox One.
Both receivers are rated at 8 ohms, .08% THD, etc. The upstairs system allows me to set impedance to 4 or 6 ohms.
In theory, the upstairs system should be louder. Better speakers, more power, etc. Correct?
But the upstairs system require the volume to be cranked to 45 in order to be as loud as the downstairs at 25. (Spock Eyebrow)
I've been through all the settings. The upstairs system does seem to be louder with component input from a Wii.
Are soundbars that efficient? Is this some kind of impedance thing? Do I have a faulty receiver? Am I missing something?
Is there any inexpensive way to test the output of a receiver?
Thanks for your advice, knowledge, and experience.
