Nice Robert. I like the roundovers on the inside edges.

I'm getting motivated with this. Hopefully, I will get more confident with the 2.25 inch thick driver cutouts. I wanted to try the difficult horizontal braces with the funny cutout first to see if I could get decent cutouts, and, I think they are pretty acceptable. Hopefully, I will be able to do the driver cutouts after a little practice with the jig.

Thanks,
Robert

Pictures of my first attempt using the jasper router jig. I really like this thing, and if you clamp the work and the circle to be cut, this thing really works fantastic. I wish all of the tools worked so well.

this is like the holy grail of subwoofer pr0n, kinda like finding the ultra rare, impossible to find Jessica Alba sex tape (not that it exists) and posting stills of it for us all to drool over.

I am really hoping that the finished product comes out as good as that jasper jig creates cutouts. Man that is fun to do. I just bought the last 8 sheets of material for a total of 15. I do have a lot of waste do to the odd sizes of some of the panels. I really think that manufacturers build the subwoofers based on the least amount of waste involved. It would really increase the price per sub drastically if they built things like this. Not to mention the weight. Just the inner layer weighs almost 175 pounds, and I still have the second layer and the third layer of the baffles=not to mention the 200 or more pounds of drivers and passives. It is going to be a really heavy monster.

I really am emphasizing getting the subs built, and working on the amps as I go. Hopefully, I will be able to get something in place to enjoy these things once they are built.

Thanks,
Robert

Spezzy,

I was really torn between getting these drivers and not. I just basically closed my eyes and dialed the phone and that was it. At first I really thought I just made a mistake, but then I settled down- I still have not even tested them. I am just hoping for the best. So onward with the build, and hopefully all will work out.

Oh yeah, I don't think I will be giving these babies up any time soon. As a matter of fact, I still have every piece of equipment I ever bought, and I don't see myself getting rid of any of that either. It is just my nature.

Glood luck,
Robert

Hey Robert,

How did you do the roundovers on the cuts? They look very even so I'm guessing it's not freehand.

jasper jig for the cutout and freehand with a 1/2" roundover bit. Comes out great with that jig.

Thanks,

Nice freehand work. I'm using the jasper jig to cut circles as well. Thanks.

"Nice freehand work."

It's hard to go wrong, other than burning; roundover bits have a ball bearing guide.

Robert,
your work looks great

Here is a link to an easy way to measure your drivers so you can make close fitting cutouts.

Hey Dan,

I started glueing the boxes today. Lots of pieces. Hopefully, I will have one single layered box assembled in the next few days. Until then, lots of glueing and aligning.

Thanks,

Robert

Robert,
I'm sure you've mentioned before, but what are you going to be powering these with? Also are your LMS's dual 2 ohm VC's? Looking great so far!

i am thinking of 2 rmx 5050's or 2 crown Itech 8000's. It totally depends on current draw available and my mindset when I finally buy.

I have a minimum of 40 amps avaiable for the LFE. This is strictly LFE channel, since my other channels have full range with jbl 2241 subs.

Thanks,

Robert

I'm not sure what the statistics are, but your 5400's may be idle much of the time; not all DVD's have an LFE track, and even if they do I don't think it necessarily means that all low bass is sent to it.

Since you'll already have separate amps for the JBL's and 5400's, you'd just need an electronic XO to relieve the JBL's of low bass and make sure the 5400's get it.

I already have crossovers that will completely handle the jbl duty.

Now, that is the reason why I am mulling over the 5050's or the crowns. I really like having separate pieces, but the crown will have all the crossovers and signal processing built in. Right now I am running with no high pass on the jbl's. They are not filtered down low, but with the click of a button, they will be filtered at about 30-40 up to start. Then, the 5400's will handle 40 down, or somewhere around that. Any thoughts?

I also used your method to measure my drivers when building my subs. So, thanks Dan!

You are all welcome.

Robert,
I use a Yamaha receiver that has the ability to crossover down to 40hz. It'll send ALL the bass below 40 to the sub, remix the center channel info into the fronts so I can run without a center and have WAY better sound. Heck I even use it to auto EQ the surrounds to match my fronts. IMO having these things taken care of this way is the best.

Dan

Regards,
Dan
