A few points I would like to make. I do not know if the Northcreek dropped resonance by adding mass or by softening suspension. I hope they leave the cone along and softer the suspension of the driver instead off adding mass. Sure it would reduce power handling but acoustically suspended it would not be a problem for this driver. The 1808 was made to handle a huge amount of power in pro applications and a few dozen of watts on the driver in a small listening shoe-box room will not really stress the driver to its critical excursion. Also, some words about the McCauley 6174 and possible other contesters. There are good drivers out there and many companies (I do not mean the McCauley – I never had thier drivers) love to say about their drivers high excursion (with is not necessary is better BTW). However, what the companies always “forget” to mention is what percentage of their excursion is in the “underhanged” mode. The driver can run even across 4 inches but as soon the driver coil jumps out of the area of the linear magnetic lines of the perfectly saturated gap then any further excursion is good only for Rap music and for the taste of the Absolute Sound “writers”.  (in fact the moment when the coil switches from the underhang to over hang more is the worst) The whole beauty of the 1808 that it has a small “emerged” coil (it’s with high sensitively as the same time – big rarity!) and “complimentary” to the small coil it has a long “active” gap. This keeps the coil move in linear magnetic invariant over a very long excursion. If I am not mistaken then it is 1.5” in undaunted mode out of 2” of total excursion! I it the highest numbers among all know to me 18” drivers and this is what set the Aura motors apart… It is from one point of view a huge waste of magnet… but is it what it sounds so good.
