@IamJF That Jantzen JA800HMQ is based of a Seas chassis and has a healthy motor on it, although not fully saturated. I'd like to see the SS cone in the Seas chassis or even a Textreme version of the SS. Currently, the Jantzen is likely the best higher sensitivity 7" on the market. I'm not a huge fan of the cone design, but the phase plug has its benefits which avoid some of the coloration due to dust cap resonances. The SS spider design is by far the most advanced.
@duvixan I'm familiar with the previous yellow kevlar cone version. To my ears, the slit cone drivers sound more natural without being boring. The kevlar cone drivers tend to be more "entertaining" with some extra harmonics. I prefer the paper sound with more gradual breakup behavior, so I can push the crossover a little higher. You can't really do that with the kevlar models due to more agressive breakup modes with longer decay times. Some people prefer the "wrinkle" paper/pulp cone drivers, but those are too bandwidth restricted and require more complicated filters.
An interesting driver.

All the illuminator drivers are top notch. Too bad their chassis isn't visible when they're installed in an enclosure.
My first serious DIY speaker was from the German ScanSpeak distributor and had a special 16R midrange with boostet magnets and phaseplug. This is the midrange but my speaker was older, with a 20cm woofer and one of their big tweeters. Sounded very homogeneous and musical.
