I got the Lepai amp with subwoofer output that supposedly has a adjustable low pass but the thing is a joke, its like a feeble failed attempt at a low pass. I can clearly hear midrange coming out of the little 6.5" "sub." Other than that the amp is pretty functional, and cheap which is nice.
I can see the obvious answer of just putting a low order passive lowpass on it for pretty cheap but I was wondering if I could get a similar effect by using a 6th order bandpass box with some generous stuffing to cut out upper frequencies.
I don't want the "sub" to be locatable because it messes up the soundstage of my future desktop speakers.
What do you guys think? Electrical or acoustic crossover?

A 6th order bandpass box could do the job, though I have not heard one yet that I liked the sound of.
If your present cabinet is sealed, it may be rolling off in the bottom at the same rate the low pass rolls off the top, with a net acoustical crossover of almost nothing.
I have a similar problem with my Technics receiver sub output, a combination of a coil and heavy felt in front of the speaker output ends up with a proper acoustical crossover around 100 Hz.
