Any advantage to an outboard crossover box?

karl: tannoy churchills have outbord xovers, as did my previously-owned avalon ascents (current sentinels also have outboard units, as i recall). there are two primary advantages that i'm aware of with such a setup. first, it reduces vibrations from the active units/box. second, it reduces the weight of the speakers, making them easier to setup and move. -kelly

Well, I'm not objective because I think they are great! The beauty of the external mount is that you can tweak it after the fact so easily. Northcreek has a page, as I am sure you know, that explains how to make simple tweeks simply by adding series resistance in the high end or cutting it out for the mids.

I make a few speakers myself and have modeled them on NC. I have a lot of respect for George Short.

I have never heard the top of the line Rhythm Signature but I am sure its great. I do not have much direct experience with the Scan Speak 9900/Revelator tweeter and actually prefer the 9500 myself but that is a personal thing.

They make the best crossovers too! I have poked my head in a lot of fairly expensive speakers and you generally don't find the quality until you reach 5 figures and often way beyond that.

Make sure you get the drivers matched as perfect pairs.

Good choice

Sincerely, I remain

I have built two diferent sets of Rhythm's the original ones with the 9500 tweeters and a set of Signatures. Both have the external X-overs. I have also built a center channel Signature that has the x-over insided and it just doesn't sound as open. There are alot of variables with the center channel verses the other speakers but I do believe you will get better results with an external crossover.
PS, I much prefer the sound of the Revelator tweeter over the 9500, jsut goes to show personal preferences.
