Magico A3 vs. Wilson SabrinaX

What's sad is that no one got my ebm tribute............

There weren't enough caps and exclamation points.

Oh I got it, but just moved along lol. 

Trackmoe,

low impedance speakers are harder to drive. Most amps struggle to put out a lot of current into low impedance loads and get hot in the process. 
The voltage out of the wall is constant So the amplifier has to put out more amps as the resistance drops. 
I=VR (amps=Voltage/Resistance) So amps go up when the resistance drops as Voltage is held constant. This also produces a lot of heat as current (amperes increase)

In your example of 91dv at 6 ohm vs 88 at 4 ohm the 88 db speaker takes twice the power and requires double the amps at the same time. The real kicker is the impedance changes as the driver moves in and out of its coil and does a job on the amplifier. 
1 volt / 6 ohms = 0.167 amps
1 volt / 4 ohms = 0.25 amps


The Sabrina looks hard to drive and will need a substantial amplifier based on stereophile’s measurements. But I am sure you can find someone with a low powered tube amp that is loving the combo... use your own judgment. 

@james633 : The spike in bass is what I'm experiencing with the SabX -
@daveyf : Yes, big difference between the Sab1 and the SabX: But still, that same issue with the bass, even though to a much lesser level.@kingbarbuda : Thank you for the info re. type of amp you are using - This is helpful - I'm trying to get a place in the DMV area to listen to the A3s...@prof : This description you are making is what I feel. I might get the CWL IV for the sake of it and check out the dynamics they're supposed to offer in contrast@james633 : Gain, thank you for your input. What I'm getting from this is that Class A, 50Watts RMS candrive such 4ohms, 88db efficient speakers. Perhaps not getting the most out of them, but still pretty good to enjoy.

I've owned the Magico A3 and my brother owns a pair of Wilson Sabrina. The Wilsons are very difficult to drive, that's a fact. The Magicos are much easier to drive because the impedance curve is much more stable, but the bass of the A3 is not well integrated with the rest of the drivers. The mids and highs are very good though and they are far more relaxed than the Wilson. Attacks, decay and tonal balance is also much superior with the A3. The Sabrinas have a very different sound coloration. They are more in your face type of speakers and you need to be more careful when pairing the electronics. Even if I like both speakers sonically, I think they are both overpriced and I wouldn't spend that kind of money on a Wilson that is so badly engineered. You have better options for less money.
