I am looking into buy a pair of bookshelf speakers, and have narrowed the field down to a pair of Klipsch RP-150Ms. However, before I purchase them, I would like to know if the amplifier/receiver I currently have will be enough to drive them in a small to medium sized room. The receiver I already own is 120 watts per channel, and is 8 ohms just like the speakers. Will this be enough to drive them well, or should I be looking into a more substantial amp to go with my speakers?
It appears those speakers are rated at 75 watt continuous, 300 watt peak power, so it sounds like they would do fine as long as your amp is decent. It is worth pointing out that using a receiver as an amp is not an ideal situation for any analysis tasks as they are often designed to color the sound rather than simply amplify it depending on the type of receiver.
