Crossover change

Hi all.  I have a Marchand Electronics crossover which is set at 100 Hz.  I was able to get modules that are set at 80 Hz.  Phil Marchand says it plugs right in. I currently have the Crites Type B which have the large 15 inch woofer.  This system already has serious bass slam. I think I will still have plenty of power from my Pass XA25.  I know I could just try this but I wanted to hear predictions about what this will do to sound quality.  Or if it is worth it.  I am not out much money either way.   We could even have a contest for who predicts the "right" outcome.

Adding a sub or two (active or passive) through the Marchand x-over will improve the overall bass response and lower the distortion levels in the bass and mids of the Cornwall's.

What main speakers do you have? And what subwoofers are you planning on using? Otherwise buying the Marchand is a waste of money!

Do you actually know how to connect an active crossover? Your preamp's main output goes to the x-over's inputs (left and right). Then the x-over's high pass outputs go to your amp's L/R inputs. The x-over's low pass outputs go to the L/R inputs on the two active subs - or the 2-channel amp/passive subs.

Without a subwoofer or two an active crossover like the Marchand is USELESS! I owned and used an active x-over years ago! The biggest improvement was an increase in headroom/dynamic range - much less amplifier clipping!

The Marchand x-over is only for use with a sub. It will drive your main speakers from 100hz up through its high pass section via your amp. The x-over's low pass section will drive an active sub or an amp/passive sub.
