Look for RMS power rating of amplifier driving speakers of the same impedance you’re using >= power rating of the speakers, or just power required for desired volume level. 3dB increase in volume = a doubling of power = halving of safe listening time, 10dB increase = doubling in perceived volume.

For example, to drive these speakers, rated for 89dBA @1W, 1m to give 100dBA (considered to be the loudest that’s safe to listen to for 15 minutes per day) at a distance of 1m, you’d need an amplifier capable of producing 2^((100-89)/3) = 12.7W RMS, however distortion usually gets pretty bad at rated power, so double that, a rating of 30W RMS would be okay.

Polk R150

Polk RTi a1

R and RTi are completely different lines. The R150 is the sister speaker to the T15 and the M10. Polks bottom barrel speakers that don’t even make it to the official Polk website.
