Just ordered one. Seems like the perfect solution to replace the current baffle step network that I have on my speakers, which decrease the sensitivity and liveliness of the sound. I have the Fostex "boutique" 206ES-R's and I have them in the vented box, as my woodworking skills can't handle the horn. They actually sound pretty good in the vented enclosure, with just a bit of shout to be tamed. The Fix's 4 db cut is actually great as my FP2 puts out enough voltage for the Paramours that they can't be turned down quite low enough (even with the greater -db resistors in the stepped vol control). I'll be interested to compare this line-level solution with the current in-speaker network solution.
