A large room and a beefy (pro audio) power amp are other parts of the equation, of course.I disagree. Professional amplifiers often rely on fans, which help lower cost, increase available power and pose no problem in most professional settings. But the noise of those same fans often intrudes in a quiet domestic environment. It's usually worth the cost to use an amplifier intended for home use, which would typically rely on heatsinks for cooling rather than a noisy fan.
