Take it how you will.

The woofer is a 15" mag d2.

Tool of the trade. Not so much for using, but for throwing at the steel walls of the garage in frustration. ;)

Call me oldschool, but I still pre-drill all the holes that I use screws in. Naturally 2 drills are used. :D

Screws weren't enough. Tnuts weren't enough! Concrete anchors are drilled into the underside of the baffle. They are cheaper than Tnuts at Home Depot. To get the bolts, anchors, and woofer to line up, I just mount the woofer in the baffle and send the drill right through the mounting holes. On the woofer.

If you're going to brace a box, brace the **** box. The MDF hole from where the baffle was cut out from was quartered and used to double over the front baffle. Very noticable result when you tap on the front.

I can't seem to cut MDF to save my life. =\

Luckily body filler easily fills in those mis-directed cuts. Almost as useful as duct tape.

Need batteries for the camera, then I'll bondo it more, sand it, and paint it. What color should I use? I got blue, black, and green.

Black matches everything.

Good job on the pre-drilling, there's no reason not to.

I think he means the bolts are screwing into concrete anchors. The anchors being mashed into the backside of the baffle

just have lowes cut your wood for you instead of you taking the risk of you messing up the cut (happens to everyone).. they put it on like a $10,000 machine (guessed the price but looks expensive as hell).. looks good I got a build going on too..

How much does lowes charge to cut the wood for you?

09-10-2006, 04:21 AM
over her, first 2 cuts are free and $.50 for additional cuts.

but..... i dont have to pay cuz i go to the self checkout:)

I (believe) that lowe's cuts it for free, but I have heard stories of them making cuts FUBAR, and just ouright ugly as hell

Never hurts to do it yourself, nothing is going to be perfect

acold7dusta: 2.0 cf net with woofer and bracing. Power is an Orion 1200D at 1 ohm. Overall I'm not sure what to think yet. It sounds good, but it's just not getting the high end like my LIs do. It's fast, accurate, and not very boomy at all. It can keep up with any bassline I throw at it, it's just not playing the high end with enough authority to my tastes. That or I have my gain and Xover wrong and it's just playing the low end with too much authority like my last box (3.1 CF NET sealed). Haven't figured out which yet. :blush:

Acreature: Underside of the baffle, not the top. ;)

Depending on who cuts the MDF at Lowes or Home Depot, you can get very accurate cuts, or very inaccurate cuts. One time I had 2 cuts of the same length go 1/4" in opposite directions. Another time, they were dead on. Talk to anyone in the know, a $10,000 horizontal saw can't cut right if the person using it can't measure right. I guess if you get really accurate cuts, be sure to remember who did it and ask for them the next time. I go to Home Depot because the Lowes guys are the ones around here without any idea how to measure. =\
