I just got done demoing/playing with them for the week. I should have an official review posted here by friday or saturday. But overall they are awesome and beautiful. Qualitatively, not a huge difference from the MKII's but they seem to be a bit more tight in the sub bass region and more enjoyable (less distortion) in the treble region, although that was just for testing, I have my midrange take care of this range usually but they can go up a little higher than most 6.5's I've played with. I just love how much bass these things put out in my leaky door, I dont know if you can find a better driver for the price [(SPL @ 60hz / dollar) - distortion].

Also, the carbon fiber woven cone is just nice a **** to look out. Makes me want to get kick panels or door pods to show them off better.

Any idea when the pre-order is over? I would be in the position to purchase a pair next month. Also, what are the actual mounting specs?

@electrodynamic would be able to answer best. But all I know is get it on pre-order before the price increases. These things are high performing and one of the best bang for the buck IMO.

Fs isn't necessarily a limitation of extension. Fs is the point of excitation, however, a driver can play below especially depending on the acoustics of the environment. There's a few other calculations to see where the driver will naturally begin to roll-off and the point excursion begins to ramp up. Modeling helps some but the acoustics of the environment still comes into play.

On paper and for upper frequency drivers, yes that's a concern. The amount of tolerable distortion in lower frequencies plus the fact that the sub still contributes in that area makes it not much of a concern. The SI isn't the only one with such a seemingly high Fs. Others have done well with such a design. Fs is just part of the the picture.

That is correct....basically the design changes have improved the speakers ability to play cleaner at even higher midrange frequencies thus allowing it to be used as a midrange driver in a 2 way system. If being used as a dedicated mid BASS driver, there ireally s not much reason to swap to the mk3 unless you just GOTTA have the looks of carbon fiber cones.

In fact, I am still trying to decide whether to use dual Mk1 ported in the doors or dual Mk2 sealed in door pods in my next build. I have bought 4 of each, so I get to choose, but there is really no reason forum to even think about the mk3 iteration.
