You don't boost to the maximum SPL, you boost and cut to the average SPL. None should be dimed, in either direction. Thanks for the advice. So, I should reset my EQ to flat, take SPL readings at each frequency, and the average of those readings will be my target SPL for each frequency? Also, how lo...

I put the finishing touches on this cabinet last night. I've already played 1 show with it as a bass cabinet and did a couple of outdoor DJ gigs with it. Here are a few pics... 002.JPG 003.JPG 004.JPG All told, I've got less than $500 in it. I ended up priming the entire outside of the cabinet. I co...

Question...exactly how should the woofer be attached to the woofer spacer? The plans use the term "attachment screws" and say that "lock washers are a must". If you look closely at the pic I uploaded of the driver spacer installed, you'll see that I have it screwed into the baffl...

Trust the plans; you NEED to use the jig to properly glue up the tweets. Laying them flat on a piece of paper and lining them up w/a ruler will not work. AND, plan on multiple coats of adhesive on both sides. The stuff dries so fast that you can put a few layers of glue on both sides over a typical...

The jig I'm using, since it is a simple flat array, is just aligning the edges of the tweeters using a 2' level. I'd say I need to sand/scrape off the old glue (super glue, and now airplane glue) better.

I began wiring up the flat tweeter array last night in the series/parallel form outlined in the plans. I'm using 24ga wire that I had on hand. I tried gluing them together with super glue, but that didn't hold. I then found some airplane glue, but that didn't hold either. I will be using some epoxy ...

021.JPG 022.JPG Thus far I figure I've got about 20 hours on this box. A lot of that time, though, was spent figuring out the best way to do a particular task or finding tools. For instance, it took me a while to figure out how to line up the top/bottom onto the baffle in order to glue it. I decide...

I got a long way over the long holiday weekend. Here are some pics...

The 3012HO came today! Very cool speaker...and weighs close to nothing! I picked up some maple plywood yesterday...closest thing I could find to birch around here. $50 per 4x8 sheet. I got 4 sheets to make the trip worth it. Should be enough to make 4 Jack12's. I hope to get 1 of these cabinets done...

Here's a pic of the crossover... I kinda know what the different parts are...kinda. Ok...not really. I'm more of a wood worker than an electronics guy. Anyway, some advice on how this thing hooks up would be great. This board that Leland made though I of very good quality. Very sturdy construction. ...

Here's a link to the post leading to the decision to build this speaker: http://billfitzmaurice.info/forum/viewtopic.php?f=28&t=20399 So, I've ordered the drivers from Leland Crooks at speakerhardware.com. I ordered 16 piezo tweeters, an Eminence 3012HO woofer, and a pre-built crossover. The pie...

I would love to see a post-mortem on this issue, as I'm thinking of a WHx build for my band. I'm no professional sound man by any stretch, but I've been playing live and loud for the better part of 2 decades. My 2cents, FWIW, is that too many instruments were being fed to the monitors. With monitors...
