    You're doing one heck of a nice job! Can't wait to hear what you think of them.

    There is more than meets the eye in building a pair of these. I have 5 + full days spent and that does not count the assembly of the sides. There is a lot of work into these and a lot of it is pretty precise stuff. I'm going to pour some more BV and fire up a Cohiba (Cuban).

    Got the first coat of finish on today. I'm going to use two coats of gloss poly and one coat of Satin.

    I'm done! I just have to mount the drivers and hook up the network which unfortunately I don't have yet otherwise I would be listening to some Chicken Shack, Jefferson Starship and Spanish Guitar by Carlos Montoya. I painted the back a tan, the same color as my walls. I don't know how that is going to work out but easily changed.

    I just opened the MA15 kit to mount the woofers and am not that enthralled with them. First the screws are way too long and drilling a hole and sucking the pronged backs into the plywood isn't my idea of neat. I'm thinking of cutting the bolts off and installing inserts instead. Has anybody done that?

    You should not care about the length of the screws! Did you get cork gasket though?

    Yes, I have the gaskets. Mostly I don't like the pronged inserts.

    Isn't it the way it's supposed to be?

    Yes, that's what JBL used but I don't care for them. I guess I'll use them anyway.

    Yes, they dig into the fascia a little but luckily they always cover them up as well. The only time you should see them is the driver is out.

    Just make sure you place them nicely the first time you torque down on the screws so that you don't end up with multiple scars.

    I think its worthwhile to pre-torque the T-nuts into place using a couple of washers and a small piece of solid wood with the edges softened and maybe even something between the wood and your nice new baffle to prevent marring. Use a dab of flexible glue to hold the T-nuts in their final position so they cannot accidentally become dislodged. This is less important when using the clamps, but I found it very worthwhile when mounting the squircle style woofers.
