You are going to have a hard time finding something readily available with a lower parts count and lower insertion loss, much less low distortion and high S/N ratio, than thishttp://www.marchandelec.com/xm46.htmlas well as having the advantage of the steep slope. Keep in mind that the lower the frequency of high pass the lower the chance of phase anomalies intruding, on the ears' most sensitive area of hearing, with any type of filter. It all depends on the response of the main driver. The generally accepted rule is to double the -3db point of the main driver. This also assumes the response of the bass augmentation is capable up to the XO point.
Is it clear that the steep slope is a better option?Chad
The reason why I find the active more acceptable in the low pass is that it allows me to have parametric control over that part of the frequency spectrum where it needs it most, and where the ear is least sensitive to noise. The Marchand passive is the most transparent that I have heard. Admittedly, I haven't heard them all. I find its simplicity and low parts count appealing.
My experience has been that any active XOs impose a sonic signature which I find unappealing.

I agree.And i also have had a hard time to find a passive XO that did not put a blanket on the music.What's left? Line-leve PLLXO and digital XO (before D/A conversion). If you have an analog source, forget the latter.
The passive crossovers we've been mentioning (like the Marchand, or something simply built into a pair of interconnects) are line level crossovers (PLLXOs), right?Chad
Chadh, you sent me a PM some time ago and I never responded. I've tried to several times but for some reason I can only rarely send PMs; almost all the time I get an error message. Anyway, if your question is still applicable, shoot me an e-mail at audiokinesis at yahoo dot com.Duke
