Choosing the Right Receiver/Amplifier
To give you the best balance of power and performance, select an amplifier or receiver that delivers continuous watts (many times also referred to as “RMS”) in accordance with the speaker’s continuous power handling rating.
For example, a Klipsch RP-8000F is a floorstanding speaker with a nominal impedance of 8 Ohms, rated at 150 Watts continuously. So, any receiver or amplifier that delivers right around 150W per channel at 8 Ohms with full frequency bandwidth (20Hz - 20,000Hz) would be a good match.
NOTE: To ensure you do not damage your speakers, Klipsch recommends the AV receiver or amplifier you choose is no less than 80% of the recommended continuous power handling, and no more than double the continuous power handling. For example, the RP-8000F requires an AV receiver with a bare minimum of 120W per channel (8 ohms), and no more than 300W per channel (8 ohms). 
However, don't be misled; although a speaker’s peak power rating can be much higher (in the RP-8000F, for example, it's 600 Watts), remember that peak power means exactly that…a momentary exposure. Trying to make any speaker perform for more than an instant at peak power is an open invitation for damage.
The right amplifier, one that has it's power well-matched to the speakers, will also eliminate the need to overdrive components (play them too loud). Which, over-driving can cause clipping, which distorts the signal and can cause serious damage to the tweeter or possibly even the woofer.
In addition, believe it or not, under-powering speakers can cause as much risk for damage as too much power can. For example, if listening to an under-powered system at a loud volume, you will be running a high risk of damaging or blowing the tweeter(s) altogether. So, just make sure your receiver/amp's power output rating is right around what the speaker's continuous power rating is.
If you have multiple speakers in your system, all with different power ratings, then you will want to gauge the receiver's output power rating based off of the highest-powered speaker in your system. This will usually be your Front Left, Front Right or possibly even your Center channel speaker.
However, it is also important that the RMS of your chosen receiver is not more than double the minimum continuous power of the smallest speaker. This is why it is important to make sure your speakers in your system are not drastically different in size and power handling.
Horn-driven speakers, such as Klipsch, are much more efficient than their direct radiating counterparts and require less power to create great sound. Just be sure to keep the receiver’s output closely matched to speaker specifications to ensure years of trouble-free performance.

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?
My RP8000f is coming i did not study before purchase, im using yamaha RX-V581 what should i do should i upgrade my receiver?
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.
