JT- It's not a guess. I asked specifically after this review came out:

http://www.audioholics.com/productreviews/avhardware/SherbournPT-700072100p2.html

The way that the review describes the Sherbourn operation seems to be what Joel found. (For those that don't know, the Sherbourn is almost identical to the Outlaw.)

But Scott posted that all bass for that speaker (set) below the crossover is redirected to the sub. That however does not seem to be what is happening.

So at least at that time, I chose to believe Scott. (Assuming that the reviewer tested wrong.) I also know that Scott monitors these threads, so it would be interesting to hear him weigh in.
