Hey, Pat. How ya doin', my friend?

If I understand your question, yes, an external crossover is available for the Revelations. It's an option for
any of the crossovers, but it is
required for the 'Ultimate' crossovers. The 'Ultimate' crossover's PPCs (
Pieces,
Parts and
Components

) are too large to fit into the speaker housing, thus the need for an external enclosure.
As for the affect on sonics, you'll probably need to ask Karsten since he's the only one who's heard it. Bob and his crew just finished a pair of Ultimate crossovers, but aside from noticing the break-in and
some improvements over the 'standard' version, I'm not sure they're in a position to fully quantify the changes you might expect.
Still cold up there?
