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.

Horns are made to use with low powered amps, You could use a SET with the 45 output tube around 1.5 watts and be in pretty good shape. I have not seen horns used with amps above 20 watts I sure you could but I have not seen it done.
5 watts is plenty of power to drive a 107dB sensitivity Avantgarde providing the room isn't huge. If the room is huge, you might not get the volume you desire.
What's the size of your room?
I have 6 watts on mine and am never wanting more..... I had a very reputable reviewer tell me I needed more with AVG.... don't know what planet that guy is on. The Art Audio PX25 amp I have is pretty darn sweet, IMHO.
