I need 1 to 2. My amp puts out up to 4.5. Lots of headroom.

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?
Hi @atmasphere, Thanks for your comment, but I am pretty sure I understand current and how it relates to solid state amplifiers performance characteristics. Sorry, but the article you refer to is so poorly written as to escape making any sense to me, hats off to you if you can understand the techno babble, with a bit of some kind of marketing. I am familiar with ohms law.
In the 70’s the power measures of peak watts and then RMS watts were shown to be grossly inadequate. This is when current came into the discussion. This is also when the first high current designed amplifiers were created. The first was the Threshold s series. I purchased the s500 after amp after amp failed to adequately power my speakers. The s500 would produce over 2.5 amps into 8 ohms and much more into lesser resistance. My next amp was a Pass x350 which would develop over 5.5 amps. This I found very amazing as I used an arc welder that produced 6 amps on constructing steel prototypes for work in the mid seventies. Anyway, through these and other high current amps I have used over the decades showed it to be a very positive guide to the solidity and resilience of solid state amplifiers. |
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. |
He more the better. there is an openness, a feeling like sleeping in birthday suit, an ease to the sound, smooth, no clipping, no mumbled distorted passages, the amps don’t work too hard, they will,sail along n cruise control doing what they do best.
I’ve had small amps, med, large, and,now I’ve learned,when you want to my e air with ease, you need the,power. sure a 6 w with 991w1m will work, but when you want to rock, you,can’t.
