Powered speakers show audiophiles are confused

17 of 23 speakers in my studio and home theater systems are internally powered. My studio system is all Genelec and sounds very accurate. I know the best new concert and studio speakers are internally powered there are great technical reasons to design a speaker and an amp synergistically, this concept is much more important to sound quality than the vibration systems we often buy. How can an audiophile justify a vibration system of any sort with this in mind.

@o_holter I just searched a measurement of the MA-1 amp and the figure they arrived at was 10.5 ohms output resistance. There are very few speakers that will not experience a huge change in their output frequency response with this amp. You have become accustomed to or just like this change to the sound so I would not expect anything else to sound at all similar without an equalizer.

Thanks for comment. Do you have the link to this measure?

Having lived with my MA-1 amps for ten years trying different speakers I do know the importance if amp/speaker matching. My point is only that even with non-optimal matching, the small speakers I tried sounded better from the MA-1.

This is a free test everyone can do, if they have a good amp. Before you pay for a pair of active speakers, check out how the passive speaker sounds driven from this amp, compared to the amp in the active speaker. You may be surprised.

This is where I found the measurement:

https://www.soundstagenetwork.com/measurements/atmasphere_ma1_mkii2/

This seems much different from what is on the website for the product, 2.3 ohms.

Frequency response with a dummy load in green. I think that is referring to the Ken Kantor circuit which simulates an 8 ohm two way but I would not have expected that dip at 4KHz. The magenta line is no load. The blue line is 8 ohms. There is a 7db difference. That requires an output resistance > 8 ohms.

["you posted a picture of Titanic going down, I was there for 6 months in Mexico filming that monster. There was only one side of the ship made so every once in a while we would have a flipped day,"]

Interesting, I like the very brief scene where surf is breaking on the beach nearby.

Paradigm? It's not the electronics, simply move on.

simply move on.

To ACTIVE speakers like you said in the OP (less money too), these have the Beryllium tweeters you like:

Why would @donavabdear downgrade from the Genelecs to the Focals?
