I have a bunch, and I’m thinking I use almost all of them. 1000 each in my Legacy IV 2 Amplifier. It runs the Legacy Focus SE’s Mains. 600 each in my 5 channel Legacy IV 5. It runs my Side Phantom’s and Rear Deco's plus the Center Marquis. All are Legacy. Not sure about the 4 subs I have. They are Legacy Foundations and have 1000 each. I invite folks over and we play video Concerts. I try to keep the system humming at 113-115 DB with my Tripplet meter. It’s better than a true live concert. The punch is unbelievable. Favorite is the Eagle’s Farewell tour. Just killer. We are 10 feet back from the soundstage. 65-inch Sony Q-Led does the video. System never heats up, and we always play the entire two-hour concerts. Can lay your hand on the Amps and they are barely warm. Sometimes we pause as I get questions about the system and its impossible to talk. But I USE my system.
Watts! How many do we need?
Got a new amp. Accuphase P-4600. It’s great. I love it.
150 watts into 8 ohms, 300 watts into 4 ohms and it has meters so I can see wattage. Have them set on freeze so I can see the highest wattage during the session.
My Harbeth speakers are not very efficient. Around 86db. Their impedance is an even 6 ohms dipping no lower than 5.8 ohms.
Playing HiRes dynamic classical recordings ( Tchaikovsky , Mahler) at room filling volumes I have yet to exceed 1watt..
Amps today offer a lot of watts some going to 600 even 1200 watts. Even if you have inefficient speakers with an impedance that dips down to 2 ohms do we need all this wattage or should we be focusing on current instead?
