Quad SP-1804 2.1 build

When PE put these on sale a few weeks ago I couldn't resist. You can't pass up a $55 18" sub. I used four of them in a nearfield cabinet in the theater and liked them so much I decided to build four for the living room to go with my KLF30s. As expected, they don't have much output below 20Hz, but they perform great over 30Hz. Soon I'll add a couple Fi IB3s to help the low end. These are in just over 3ft^3 sealed cabinets. No EQ in that REW graph. It's just running off an NX6000

Thanks. I've used that paint on a few builds now, love it. I looked for your build thread yesterday but couldn't find it. Weren't you also doing an SP1804 build?

Rust-Oleum Paint and primer in one. The rattle can with the fancy trigger head. Lowes, Home Depot, Walmart all sell it. It sprays a nice fan instead of a round pattern. Goes on very nice for a rattle can.
