The MiniDSP would work nicely, because you can use it to set whatever low-pass frequency and slope you want. I'd probably lean towards that since it gives you such flexibility. Sub crossovers are easier to dial-in than the crossovers inside the mains. Measurements help, of course, but you can set the subwoofer low-pass pretty well by ear.

Remember - we don't high-pass the mains when running flanking subs. We only low-pass the subs. Actually, you can rolloff out-of-band signals by high-passing the mains at 40Hz, but don't go higher than that. We want the mains and the flanking subs to blend in the room's modal region.
As an aside - speaking of that cheap Pyle crossover - I've found a lot of companies are branding and selling the same unit. I wouldn't suggest it without the upgrades though:
