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.

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.

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 Corn's will sound more seamless/balanced and you will become younger and hipper in spirit (replacing your Nu Balance's with Converse Chuck Taylor low tops).
