"I see most people are using active crossovers. Why isn't simple line level low pass and high pass filters a good idea?"I may be nit picking here but "Line level" refers to the small
signal(s) between components before it's amplified by the power amp and sent to the speakers.Active crossovers are considered line level components so my question to U is, are U refering to high level or speaker level crossovers in your question or R U refering to implementing a line level X-over before the power amp(s) using discreet components?

Ok.There R several companies out there that offer line level in-line x-overs like U are interested in and Harrison Labs is one of them.
I've included a link to the PFMOD 2W-1 that U can peruse and if this unit piques your interest, I have one I am no longer using that U can try in your system if U want.

That is a very nice offer. I looked at the site, mentions low pass is mono, can it also be used sterero? Is there a way I can contact you? My E-mail is fred_troy@hotmail.comThanks again,
Yes, the website mentions that the low pass is mono-mixed but the instruction sheet that came with the unit makes no mention of this and indicates that the low pass section has left and right outputs.The low pass frequency can be selected independantly for each channel so this would indicate that the low pass is in stereo.
I used the unit with a single sub so I never explored the stereo sub route.
I will contact U via E-mail.
Cheers,
