FS: In Los Angeles: four 12" budget subwoofers

I have FOUR Elemental Designs EHQS 12 subwoofers I purchased for a project which didn't end up happening.

This is a well-made subwoofer that doesn't compete with $100 or $200 each subwoofers, but sounds totally decent, and with four of them, it DOES compete with pretty good individual subwoofers.

There are a LOT of posts about this subwoofer on the internet, as it was offered for the ridiculously good price of $40 each when it came out. I'm selling it for half of that. $80 for all four. These are the 4 ohm version.

Here are some threads about the subwoofer, including box designs, the first is the official thread from the manufacturer:
