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.

Assuming the doubling of effective power per every 3db sensitivity increase (assuming both sensitivity and power are measured correctly), 5 watts at 107db is the same as 320 watts at 89db. For most 89db sensitive speakers, 320 watts would be considered fine and another 20% (5 to 6) would probably enough overhead.

I don't see a problem with 5 watts...
