One of the more unique aspects of the ULP is the utilisation of an active crossover rather than the traditional passive crossover found in 95% of commercial designs. Then you need to design active electronic custom crossovers, or use achieve the same use units such as Mini DSP. If one were to design and build their own active crossover, you save a lot of cash on the passive crossover parts. If you only require filters which can be made passive then passive crossovers can be great but otherwise (if you require other filter types) then you have a design problem. A passive crossover has the same job and it is designed to work just like a active crossover.The only big difference is they make your car audio system less efficient this is because it filters out audio signals that have already been amplified. Isn't this technically no longer an active crossover design? As I understand it, having an "active crossover" implies that the crossover is happening *before* the amping step. I have a CX3400 which I help each other. Then you need to be sure the SNAXO can work around the B&W xover points, or you design your own active crossover. Lets start by describing an active crossover. GND, V+ and V- are power rails, LIN and RIN are the left and right inputs, and LHPO, LLPO, RHPO and RLPO are the left/right high/low-pass outputs.

I have a pair of Quad ESL 63 and am trying to design an active cross over. Then you need an amp for every frequency band the speaker requires. The A2 differs significantly from the Atom in having a relatively rare sealed cabinet, as opposed to the Atom's rear-ported, bass-reflex design, and an active digital crossover instead of the Atom's passive one. Yes they can, problem is it means you have to removed the crossover & that has resale implications. This is only semantics, but I am still curious. This is my design for the crossover filter, with a steepness of 24 dB/oct. Also I found this thread, active filter without opamps with the link to Naxo active crossovers by Linn/NIAM. Also, B&W Nautilus speakers use an active crossover design that allows each driver to operate on its own frequency unlike the more-than-common passive crossover designs.
