What amplifier does the Sony SS-CS3 need?

Pick a speaker and tell us how loud you listen and how big the room is. We work out the power it actually needs, check which amplifiers can safely drive its impedance, and rank 293 amplifiers against it.

Your system

Four questions. Nothing is hidden on price.

Passive speakers only - a powered speaker already has its amplifier inside.
Changes the order only. Nothing is hidden for costing too little or too much.

per channel, into 6 ohms

To hit 95 dB peaks at 3 m from a pair of Sony SS-CS3, you need at least 16 W a channel. More than 145 W is wasted here - that is all Sony rates the speaker to take.

Show the working
  • 95 dB target at the seat
  • +4.8 dB for 3.0 m of distance
  • -3 dB for a stereo pair
  • -84.8 dB effective sensitivity
  • 1.2 dB taken off to convert the 6 ohm 2.83V rating to dB per watt
  • 2 dB allowed for optimistic published sensitivity
  • Published sensitivity 88 dB, used as 84.8 dB per watt.

Were these amplifier recommendations useful?
It helps us tune the matching, and we read every comment.

Sensitivity and impedance figures are the manufacturer's own. We read sensitivity as dB at 2.83 V/1 m and take 2 dB off it, because published figures run high. Treat the result as a well-founded starting point, not a measurement. Full Sony SS-CS3 specs.
