    Will the R-625FA be able to handle 150W continuous without damage?

    Having extra power within the receiver is actually a benefit. It will give you greater volume and clarity at lower levels. However, you must be careful you are not pushing the speakers too hard. Make sure you are not pushing that receiver more than 75% on the volume knob and you should not have any issues.

    I picked up the Atmos bundle from Costco. Do I pick the receiver purely on the 100w R-625FA towers or do I need a receiver that's a lot more than 100w to cover the rest of the bundle too (Bundle plus an additional two R-12SW subs)? For example, would a Marantz SR5015 be enough and safe for the setup? 5.2.2 setup.

    With the system you are describing, you will want to follow the RMS of the R-625FA (100W per channel into 8 ohms). The R-12SW is a powered subwoofer, meaning it will pull its power from the wall outlet, not the AV receiver. The receiver will merely send a passive signal to the subwoofer via RCA, which will then be amplified by the built in subwoofer amplifier.

    Hello!

    I am new to the home audio world and am learning as much as I can! I currently have ordered a klipsch dolby atmos 5 channel setup (7 with the height speakers on the tower). The towers are 100 watts continuous front and 75 watts continuous top. The center speaker is 100 watts continuous. The bookshelf speakers are 50 watts continuous. The sub is self amped.

    According to this page, I should match the av receiver output to the highest, so 100 watts continuous. Is this correct?

    Also, I am very confused as to how to handle the 2 channel driven spec. I can find many that are 100 watts per channel 8 ohm, but they're all 2 channel driven, which means 7 channels will be far lower output. Will those work for my setup?

    Yes, Brandon King, you are correct. You will want to find an AV receiver with 100 watts per channel into 8 ohms for that system. I would not worry too much about the loss of power when driving all 7 channels, but if you find after setting up that you want a little more volume or definition in your sound, you may want to look into a slightly more powerful receiver.

    Alex Hua,

    The Yamaha RX-V581 produces 80 watts per channel into 8 ohms, but the RMS of the RP-8000F is 150 watts per channel into 8 ohms. Klipsch strongly recommends finding an AV receiver with a MINIMUM of 125W per channel into 8 ohms in order to power the RP-8000F for long periods of time without damage.
