Hello,
I am new to all this and I just bought 2 RP-260F and a RP-450C for black friday. My plan is to run 3.0 for HT and 2.0 for music to start off and slowly as my budget allows, start adding more speakers for a proper HT setup. I am trying to now buy a receiver but I am confused to what kind of power I should be looking at?
For context here are the following stats:
- I sit 9 feet or 3 meters away from the front
- Current living room is 9ft high, 17ft long 17ft wide = 2600 cubic feet. This does not include openings to a hallway, kitchen and den. (It's a condo)
- RP-260 sensitivity is 97db at 1 meter
- 6db is lost for every doubling of distance from the speaker. Therefore, if I sit 3 meters away, I lose 9db in volume
88db @ 1w
91db @ 2w
94db @ 4w
97db @ 8w
100db @16w
103db @ 32w
106db @ 64w
109db @ 128wIt's my understanding reading around that the reference peak level you want your speakers to be able to hit is 105db at the listening position. Based on that it looks like I should be perfectly fine with an receiver that can deliver at least 64w. What I don't understand is why everyone is pushing for expensive $800+ receivers and in some cases, adding an amp as well to power their speakers? Unless they are sitting more than 3 meters away from the front, why would you need that much power?
And how does the 125w continuous power handling spec fit into all this? I can't find the link link anymore, it was an article from Klipsch recommending that you don't go below 80% of the continuous power rating. Which in the case of the RP-260 is 100w = 125x.8, which is much higher than the 64 watts it seems I only need.
What am I missing here, do I need a receiver capable of 100w or 64w for my needs?

I looked at test benches from Sound and Vision for the Pioneer VSX-832 (CAD$389.95) and the Sony STRDN1080 (CAD$599.99) and the power test ratings seemed pretty adequate.
Pioneer VSX-832 (bench)
2 Channels driven (8ohm)
106w @ 0.1%THD and 122.5w @ 1%THD
5 Channels driven (8ohm)
70.4w @ 0.1% THD and 81.9w @ 1% THD
Sony STRDN1080 (bench)
2 Channels driven (8ohm)
98.9w @ 0.1%THD and 121w @ 1%THD
5 Channels driven (8ohm)
66.2w @ 0.1% THD and 90w @ 1% THD
7 Channels driven (8ohm)
64.4w @ 0.1% THD and 75.5w @ 1% THD
Compared to a Denon X3400H (bench)
2 Channels driven (8ohm)
123w @ 0.1%THD and 147w @ 1%THD
5 Channels driven (8ohm)
97.6w @ 0.1% THD and 106.1w @ 1% THD
7 Channels driven (8ohm)
72.7w @ 0.1% THD and 80.8w @ 1% THD
Looks like the Sony or Pioneer would be adequate for my needs vs the more expensive Denon?
