Crossovers, why so few options?

It seems like if you're in the market for an external crossover, there just aren't many options, particularly if you don't want a piece that belongs in a rack mount (e.g. Behringer, Rane).

Why is this the case? It seems like external crossovers would be in pretty widespread use, but the selection is much less than in the amp/preamp space. On all of Audiogon, there are only two or three crossovers for sale at the moment...

Kal...The passive crossover elements which address driver characteristics can be retained while the basic HI/LO filtering is done at line level.

The MG 1.6 crossover is a simple HI/LO divider and has none of the extra elements that Kal refers to. It is, therefore appropriate to consider for biamping. However, the stock crossover does have different break frequencies and slopes for the HI and LO sections. If this is not duplicated performance may be degraded (or, perhaps, improved).

Stilljd...Experimentation is always interesting. I have not biamped my three MG1.6s unless you count the Subwoofer/mains as biamping. I did rebuild the passive crossovers using AWG10 air coils that are externally mounted. Because my Maggies will not have to handle SW frequencies I figured that the woofer panel could go a bit higher. My Woofer/Tweeter crossover break is about 250 Hz higher than stock. By the way, this saved a few bucks on the three AWG10 inductors, and the tweeter capacitors. I am well satisfied with the result.
