Well, you could use a passive high pass as well. However, the Harrison Labs F-Mods seem to use only capacitors inside, so the "12 dB" models I tested a long time ago had a response like Q=0.5, that is to say very gentle until well out of the passband. And maybe the -3 dB point was not exactly as specified. Any passive crossover needs to have the actual response checked at the output of the amplifier!
The main use is for people who don't want the expense of an active crossover.

well, yes you could, but would your high-pass filter be in phase with your low pass filter around the crossover frequency? (hint: no, not really).
yes you might get away with it, as it also depends on how the two sets of speakers interact, and how much phase shifting is going on at those frequencies, but then again you might just end up with a great big hole near your crossover frequency.....
just glancing around the Behringer CX2310 is 9100 rupees (USD $152)

RJF, I have used one of those in past and they do the job. I would support this recommendation, i.e. active crossover before the power amp, the maintain the current config of one channel for the tops and one channel for the sub. Fairly cheap and effective.
This unit uses 24db octive crossover sections is there an EASY way to convert it to 12db.
Rember I said easy!

The 24dB/oct slopes are fine.
An active crossover will leave your system mono without the addition of another amplifier. If that's okay, then you'd use one side of the crossover, set to 80Hz, and feed the highpass through to the tops, low-pass to the sub. Make sure you engage the 25Hz filters, too.
You can make sure the desk output is mono by sending everything to the submix, and then pressing all the buttoms just above the submix faders. That way, each of L&R of the submix is fed to the main outputs, so both the main outputs are mono, passing the same signal which would go to the crossover and amplifier.

I want built Martin King's OB and this design calls for a 12db crossover set at 200hz for the woofer and a 12db crossover for the full range driver set at 500hz. That is what the design calls for not 6db, or 18 or 24 but 12db. Heck I will just build one as all I want is the 200hz 12db low pass section as I will use a passive crossover for the full range driver.
Start your own thread, then.
I mean, come on, this thread isn't the right place to ask questions about a totally different topic.
