Is 5 Watts enough for Horns ?


How much power is enough to drive a 107dB sensitivity Avantgarde ?
Is 5 Watts from A 300B SET enough?
Consider that the Subwoofer of the Avantgarde has its own high power amplifier (each woofer 500 Watts)so the work in the bass department is largely taken up by the subwoofer amp.
I have seen McIntosh MC501 power amps connected to 107dB sensitivity Avantgardes and seldom did hit the 5 Watt mark on the meters when cranking the volume up to hurting levels.
0.5 Watts was what the meters show at normal listening levels.

Sweet System !! The Art Audio and the Avantgarde's must be a nice match. I have heard people say that 8 watts of that amp can drive you out of the room. Plenty of power.

Eljaro,
Give what you have a try and if you think you need more go to a dealer and barrow a more powerful amp and give it a try. I think you will be fine though.
300B amps are fine on Duos. I've since switched to 18 watt "behemoths" (Lamm ML2), but for sonic reasons, not lack of volume capability.
The David Berning headphone amp only put out about 1 watt is plenty of power for my avantgarde horn..but I prefer the 300B amp for my horn..
