band pass subs with 1850s

I'd like to design a box that had the same frontal dimensions as 1850. Depth could slightly more if needed. 2x18" or 2x21" would be my starting point. -3dB around 25Hz. one of these with two 1850 horns on top could make nice stack.

Toasty how does Arc X + VLF work in real life? Of course mostly it will sit there doing not that much but does it compliment the smaller bass well?

It's not hard to come up with a double 18, even double 21 cab, the size of 1850 horn, but as said, you'll need a lot of them and give them very serious power. Wanna create a monster.... gotta feed it.

I know they will be power hungry. I know they will be big, but they will not be nearly as big as a horn that could do what I want. The 1850 is a great audible bass speaker, but I just think I end up overprocessing them trying to attenuate 100hz so you can hear the 48hz. With a dedicated sub, I could let the 1850 sing the bass, and not try to force it to behave in a way that is just not in its nature. Trying to get more sub out of the 1850s is dangerous for the drivers too, so doing something like this could give them a longer cone life. I don't need to be flat in the sub area to the rest of the volume. I just need something that does not need a steep HPF at 50ish hz so that the bottom end curves off a little more gracefully.

Are you sure? If you use them in blocks of four almost all of the time, things like EM Quake and Psyco Sub take up not much more volume than an 1850 Horn and do 30Hz with ease.

EQ the midbass down?

I once measured stack of four 1850 horns. -3dB @ 43hz. +-3dB 43hz-200hz. No peaks in upper range either.

Having less than four in a stack resulted in loss of sensitivity between 40 to 70hz or so. With single box there was difference of almost 10dB between 60hz and 120hz, it was pretty much like a shelving filter.
