Re: an active (or passive)crossover is:

First let me say that you guys kick serious a$$!! Thanks for your time.

Regarding the XO freq., B-G used to XO the 520 at 325 Hz but then changed it to 500 Hz according to the .pdf product file on their web site. I don't know why but I figured they must have a good reason to do so.

This is the system I'm "married to" since it belongs to a friend who's overseas.

Pre-Amp: HK Signature 2.0 http://www.harmankardon.com/productlines/displayspecs.asp?id=30&cat=amplifiers

Amp: HK Signature 2.1

Front Speakers: B-G 520DX

Center&Rear: B-G 220DX, MMG

Sub: ACI Titan II


The pre-amp LFE XO is hardcoded at 100 Hz. The idea is to use 4 channels off the amp (150W at 4Ohm), 2 for each speaker.
