I've had this HU for awhile now and very pleased with it myself. Regarding the X-over slopes, they can be switched from Through, 6, 12, and 18db per oct WHEN you choose 2-Way or 3-Way mode in Audio Setup. In Normal Mode, there are fewer x-over freqs and the slopes are set at 12db/oct. And yes for an active setup, the HU is fully capable, with Hi and Low pass for mids and subs, and Hi pass for the highs. For all channels you can also switch phase and apply Digital Time Alignment, as well as Speaker Gain Adjustment. The EQ can be switched from simple B/T (Bass 80Hz, and Treble 10kHz) to a 3 band Parametric Eq with adjustable center freq's and Q. Overall a great HU. The "Slidetrack" interface is a little awkward, and I'd prefer it had the traditional rotary knob, but it's easy to get used to and the features make up for it.
