B & W 686

I am planning to buy a pair B & W 686 speakers. I checked the specs of this speaker and it was stated that the recommended amp power is 30W - 100W into 8 ohms on unclipped programme. However, I am planning to buy a stereo amp that has only 20 W in 8ohms. Do you think this is fine? Will they work together?

In the amp info, it was stated that the power is 2 x 20W/30W at 8ohms/4ohms (both channels driven)

I'd sure listen to the combo first.

Re: B & W 686

You may be OK w/20-30 watts. But to stay on the safe side, you should probably consider 50w/ch@ 8 Ohms as a reasonable minimum. The amp you buy should also have a 4 Ohm rating of 75-100w/ch. I think you'll be happier longer that way.

Re: B & W 686

Thanks. However, I am still confused the concept of the right amplifier for the right speaker? Is it really the impedance matters or the power?

Re: B & W 686

I'd plan on buying different loudspeakers or a different amp. The B&W 686 is a surprisingly inefficient loudspeaker at 84dB/2.83V/1m and therefore will require the power suggested by the manufacturer. It will sound best toward the higher end of the range. I have experienced amplifier clipping with a 35 wpc amp and 87dB/1w/1m speakers at volumes most people would not consider exceedingly loud. If the B&W 686 are the loudspeakers that sound good to you, you will have to get amplification to complement them. I always believe that more clean power is better.
