Just recently finished this build and I'm incredibly satisfied with the output. It's amazing to have real bass now!

I don't take a ton of pictures while I'm working, so let me know if want a more detailed shot of anything. Cabinets are built from two layers of 1/2" birch plywood. I then covered with paper backed cherry veneer. I ripped solid cherry into 1/2" strips for the corners so that I could do a round-over...Flash made the veneer look a pretty "stripey" in some of the pictures. It's not nearly as pronounced in real life. And another thought, anyone that doesn't use Speakon connectors is just crazy. Those are the best connectors I've ever used and they are super cheap.

I'm powering the pair with a Crown XLS1500, 2ohm stereo for about 750 watts per cabinet. The Crown is getting its signal from a Marantz SR5006.

I went from an 8" Mirage sub to this pair of dual 12's. The difference is pretty substantial to say the least.

I still have some arranging to do (hiding speaker wire and moving the satalite speakers up to the wall), but they are pretty much going to stay where they sit.

So, let me know what you think.

The grills were made from 1/2" mdf and I'm using some super strong magnets to hold them on. I got the magnets at Rockler.com. And I got the grill cloth from a local fabric store, nothing special, just dark brown with a little stretch to it.

Wow. All I can say is the workmanship is first rate. I am absolutely encouraging any one with a restricted budget to give these drivers serious consideration. The output for the $$ invested is very hard to beat and build quality is very good on these drivers.

I know you have to be happy with what they are doing for you. Four of these have to be blowing you out of the chair.

An audiophile likes to talk about how much they spent and how good it sounds.

A DIY'er likes to talk about how little they spent and how good it sounds.

Thanks, and I am completely happy. My overall spend was still kind of high because I had to buy the amp and because I used more expensive plywood (vs mdf) and cherry veneer. Even taking that into account, I'm sure I'm still ahead of the curve for $ vs output.

I'm counting the amp in a separate category though because I'll be able to use that for future projects...

Very impressive indeed. You did a real nice job on those.

If you take yourself too seriously expect me to do the exact opposite

Nice, very clean build. I wish I had skills like yours to build such nice cabs.

Thank you guys. I'm very happy with these subs. As many others have said, they are really hard to beat for the price.

I hosted a family party over the weekend and my brother and sister in-law both stayed late to hang out. I put in transformers 3 because the BIL hadn't seen it and I figured there would be some good action scenes to show off the subs. He couldn't shut up about how awesome it sounded with the new subs. And he had never really heard my fronts being played loud either. The fronts are Zaph SR-71's. I've been telling him for years that I can build him speakers and/or subs that would kill just about anything that he could purchase from Best Buy, but he never wanted to commit to letting me build anything for him. I think he finally understands that Blose suck and that he spent waaaayyyyy too much money on that Martin Logan sub that he has. I tried to talk him out of buying that sub because I wanted to build him something better, for less money.

The eek.gif expression on his face for the entire movie made me a happy camper. If I get that reaction out of everyone that comes over for a movie then I don't care how much I spent, it was worth every penny!

These look fantastic! Very inspiring to me as I've been trying to figure out what kind of box I want to put my Stereo Integrity 18's in. I've been kicking around the idea of making curved sides that taper towards the back of the box but have had such a hard time figuring out the details in order to have the sides nice and rigid. I may just have to go with your design and put two pieces together at angles on the sides instead of doing curves. Mine would be two separate boxes with one woofer in each, so picture yours cut in half vertically.
What are the dimensions of yours? Specifically, how wide is the front baffle compared to the rear and how deep are the sides flat versus after the angle?
Also, great job with the veneer. I will also be attempting to do a cherry veneer on whatever I end up building.

Not sure how I just got around to seeing these. Nice job. Great value. So, where are #3 and #4? tongue.gif

BTW, you do know you could have shelled out just a couple more bucks and bought a Genelec 7073A, right? smile.gif
