Howdy,
I have a circa 1988 Yamaha RX-700 natural sound receiver I purchased brand new in High School. I've been using a pair of vintage Altec Lansing 83 (100 watt, 8 ohm) bookshelf speakers in my 13' by 16' living room. Not great sound, for sure. I'm trying to decide which of two options I should chose, both are used DCM speakers which seem to be highly regarded, especially the TF-600.
But, is my amp too under-powered for the TF-600s? Should I go for the CX-27s instead? Thought I'd ask the experts!
My Yamaha receiver has the following specs:
Power output: 65 watts/channel into 8 ohms stereo
75 watts/channel into 6 ohms
Speaker load impedance: 6 ohms to 16 ohms
frequency response: 20Hz to 20kHz
Option 1:
DCM TimeFrame 600:
recommended amp power: 10 - 250 watts
max power handling: 250 watts RMS peak
6 ohm nominal
frequency response: 30 Hz to 20kHz
or option 2:
DCM CX-27
recommended amp power: 10 watts to 150 watts
max power handling: 150 watts RMS peak program
6 ohms nominal
frequency response: 35Hz to 20kHz

Theyare similar in efficiency and sensitivity.
Your amp is fine for either, listen to them both, and see what you like better in your room.

A speaker can't overdrive an amp, it works the other way. The power rating of a speaker should be the max power that the speaker can sustain before a damage can occur (for example shorting the voice coil). In your case the amp shouldn't damage the speakers as it can't output too much power. However never drive an amp near its limit because of high distortion that can easily burn a speaker even if it seems that the power is lower than the power rating of the speaker.
Having said that, with 92-93dB speakers and a fairly small room, you'll use very few watts before the sound is too loud.
