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...

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).
Eldartford,

Nice to talk to you again. You're correct about Maggies and the assymetrical slopes and frequencies. The Bryston gives just enough adjustability to pretty closely match the stock settings and experiment a little with different combinations. I dabbled a little with measurements to let me "visualize" what I was hearing. Two observations:

You can make different combinations of high and low pass slope settings (with frequency adjustments) measure the same, but the presentation is different. I am no "golden ear", but it is really obvious to me.

"If this is not duplicated performance may be degraded (or, perhaps, improved)."

I actually prefer symmetrical 6db slopes (1st order) with the active crossover. The sound has more "clarity" (for lack of a better term). For my room and tastes, I prefer a different setting from "stock".

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.
