Onkyo TX-RZ70 11.2CH AV Receiver - Official Support Thread

[PENG]

Thanks for your gracious response here PENG - I am appreciative for the offer of assistance and I might take u up on that once I'm a little more established.

In the interim, would you mind sending some links to "one of those online calculators ...." you refer to. I'll start tinkering around a bit and keep you posted.

Thanks

The ones that are easy to use are:
Peak SPL Calculator
Crown Audio - Professional Power Amplifiers | English

More capable/flexible ones:
Amplifier power / SPL calculator for home theater THX reference level - Acoustic Frontiers LLC
Amplifier Power Requirement - Google Sheets

One that covers more use conditions, imo not the best but close..
Amplifier Output Calculator - Benchmark Media Systems

There are too many to list, and I created my own, if not, I would say the simple Google sheets based on is among the best one.
