"As an aside, I don’t think I will ever forget (or forgive) a rival magazine for rating the Q-5 as “bass-shy” and some Wilson or other as “full-range,” when the Q-5, by the very measurements that this magazine touts and depends on, went linearly down into the 30Hz or lower range, and the Wilsons dropped like a stone below port resonance. (There is a reason why even the most expensive Wilsons have to be augmented with gigantic subwoofers to generate really low end.) The reason for this injustice was simple: For most bass lovers, low bass doesn’t matter. Let me say that again: For most bass lovers, low bass doesn’t matter. Fender guitars and kickdrums live in the mid-to-upper bass and power range, and having FR peaks here does give such instruments the slam they have in life. As I said at the start of this endless blog, it is one of the peculiarities of measurement-based designs that flat frequency response and low distortion don’t necessarily translate into greater “realism” (or realistic excitement) on certain types of music, particularly rock."

Ouch.
I never found any Magico "bass shy". Quite the contrary.

My S5 speakers are anything but bass shy. But they have to have the right amp driving them. Without appropriate current and impedance matching they can sound less forceful on the low end.

I'm not real sure what he's trying to say here. Like he's implying that sealed speakers go lower because they roll off at -12db/octave under tuning where ported is -24db. There's usually a point at something like -15 to -20db where the sealed speaker is again higher in amplitude, but who cares, it's 15 to 20db down. And it's port tuning, not resonance. Port resonance is a completely different (and bad) thing determined by the port dimensions and geometry alone and contributes to midrange coloration, port tuning is the port and cabinet working together to boost bottom end in a predictable way.
I'd imagine that's true. With a 2.8ohm load and -50 degree phase angle, they have potential to drain the power supply reserves almost instantaneously.

I can guarantee that the S5's bass will literally pound you just as if you were being punched, if enough power is used. On the other hand, the other drivers might not be able to handle that much power.
Of course they can't handle as much power, but they won't ever be asked too. Assuming proper crossover design midrange and tweeter are rarely the drivers that run out of steam first.

Valin wont forgive nor forget .....
its funny how tier 1 pundits can spin the science when it fits them, bad measurements never matters , i have never seen a speaker measure 3 dB down at 28hz and sound light in the bass, wonder how many Magico owners running with more than 300 watts /ch.

There's a big difference between -3db @ 28hz anechoic and -3db @ 28hz measured in room. It's easy to see how the later could still produce a speaker that sounds lean, because below 200hz you're measuring the room just as much as you're measuring the speakers. Move the speakers, move the mic, and your measurement will change completely. Now suddenly you could see a graph that shows -10db @ 28hz.
That's why to properly show how the speaker is performing independent of the room you need a combined time-windowed far-field measurement with ungated nearfield of the woofers, and then you need to blend in a measurement with the microphone right at the port opening if it's a ported speaker.
Stereophile does get it right that they show both types of measurements.

Yes and no , mixing gated and nearfield pressure measurements of ports and woofer is a good compromise , scaling is an issue especially with port velocity , I have never seem it match anechoic measurements when done , if its raining or bad weather i can understand and I have always taken John to task why not drag the thing outside and do a full GP measurement , frankly you don't get more accurate even in a Chamber ...
As to -3db @28hz , I was referencing anechoic , if at the listening position , there is truth in what you say there could be nulls at other areas of the room and have a suckout , where the speaker will sound leaner , with less bandwidth, but it would take a really bad room situation to have it sound Lean and thin.

You can do a ground plane measurement in-room you know. Taking outside measurements is just a pain, dragging all the needed gear out. And here there's a high noise floor outside because of all the frogs
