10L Bass Reflex Boxes, constructed of 5/8" ply, covered with decorative paper.
They have wireless receivers from cheapo Home Depot speakers on the back.
Cones have been treated with 3 thin coats of Mod Podge.
A baffle step correction (BSC) and Zobel filter have been included to tame the top end.
This is a sample of the sound - since the mic is just a cheap Canon PowerShot digicam, don't read too much into it. They sound very balanced, bass isn't huge but nevertheless present.
