MEADOWLARK HARRIER CLASSIC

Let's take a look at the Harrier's woofer, Satori WO24P-8. Just me, I'm a push-over for a pretty face.

Along with its smaller coworker. One serious, modern woofer.

Symmetrical spider. Lots of ventilation. Satori's signature decoupled motor. The long coil needed for long excursion necessarily has a large percentage of itself outside of the magnetic gap. All things being equal, this results in lower sensitivity. But in this case we buy back that loss with a nuts-o magnetic structure that focuses plenty of flux into the gap.

As an aside: the coil length/sensitivity trade off is the dominant way that the "high sensitivity" guys achieve their ends. There is a practical limit (which is always being challenged, but still) on flux density. Once you're at that limit (which most of them are not, but still), the two ways you buy sensitivity are shortening the coil and softening the suspension by using a foam surround instead of rubber or nitrile.

For longevity reasons you do not want a foam surround.

For bass extension/output reasons you do not want a short coil. Your useful excursion will be so small that you'll go nonlinear way before the fun starts. When the moving system excurds past its linear range, it's going balistic and relying on the elasticity of the suspension and the box's air spring to recenter it. That does not sound good, to say the least; the resolution goes all to hell. And because the bass system isn't holding up its end of the bargain with the rest of the system, the thing goes bright or hard.

With this product we're addressing guys who may be inclined to head down that old school road by showing them a much better path: a highly capable bass system with more than enough power to control it.

Always such great technical explanations in your posts. Gets my nerdy engineer juices flowing.
