Make sure you seal your edges guys.

The MDF/Chipboard on these isn't the most stable material. Run a bead of woodglue along all exposed edges and rub it in with your finger. Also, make sure to coat the inside of any screw holes to stabilize the material. For this you can use superglue and chase with a screw (immediately remove) if you plan to be unscrewing/rescrewing several times, if not, woodglue works fine.

Also, if you're using the sanding drum expansion method, you may find you have a less than true hole. Specifically the "bottom" of the recess may retain a lip. Fortunately this nice soft MDF can be easily scraped away with the appropriate flat-head screwdriver. Just scrape it around a few times and you can make sure the bottom of the recess is as open as the top.

I have used them for several projects, most recently, the addition of a rearfiring 12"+horn to the "big" rig. Click the image to open in full size.

That's a JBL 2206h with my own flavor supertweeter per Building A Budget (Super?) Tweeter Reaching the stratosphere! Article By Jeff Poth

Crossover is a damped 2nd order electrical on the supertweeter, with a notch, and the midwoof wide open (the 2206h is very well behaved on the top end). Effectively it's about 3rd order at 2500.

They are pretty, but so far pretty empty in my garage. Free boxes ended up with me buying a LOT of various drivers and related items, but haven't had time coincide with space to mess with them. I have the nagging feeling that I may have bought the wrong impedance drivers for my duo woofer subs, but soon I hope, soon.
