Ran to HD at lunch and picked up 2 sheets of Baltic Birch. Build will start Saturday, so I'll post a few pics then.

Each box will be 3^3 @ 34Hz and housing a 15" RL-P. ONLY way to find out the difference compared to the 2.5^3 @ 30Hz boxes I'm running now.

And I like making sawdust and wanted to try the BB as I've never worked with it before :naughty:

Looking foward to the build, should be a very intersting comparsion. and thanks for the advice the other day.

Not chilly, balls a$$ cold!!! But I have a torpedo heater so it's all good.

Got all the panels cut tonight. I'll get some pics tomorrow during the assembly. Eyes are burning too bad from the heater to deal with the camera right now. If I left the garage door cracked open for fresh air then the snow would blow in.

BB makes very little dust compared to MDF - FTW

A good friend gave me this on permanent loan last summer, sure makes cutting things easier.

4 degrees outside, so I have to fire up old faithful. I've had this thing for 18 years now. Paid $50 for it back then.

Cuts came out pretty well considering I could barely feel my fingers. Only problem was my math at 2am was less than stellar, so new specs are 2.9^3 @35Hz, thanks to cutting a few panels 1/2" short :furious:

Moved things inside to the gym to assemble the first one. Really wanted to use my new nail gun, but figured it was too cold for the glue.

Countersink bit FTW. Used Titebond III as I picked up several big bottles for $4 each on clearance.

Finally got to try out one of my Jasper jigs. Only issue I had was the BB is so light that the d@mn box wouldn't sit still while I was doing the cutout.

Flush bit, roundover bit, and a hand sander and she's looking pretty good. But some idiot forgot to put the bracing in, so I'm heading down to do that now. Then a little finish sanding and stain.

I'll start assembling the 2nd box tonight. Think I'm going to just throw some stain on them for a different look.

One other interesting thing happened. When doing the driver cutout I was getting ready for the 3rd pass and I see smoke. Look at the sawdust in the groove and it was on fire!!!! Didn't hit a screw, so not sure how it caught on fire. :eek:

lookin good

but why would you build two boxes, only to throw one away? shouldve whipped some graphs up to see how it will act in each enclosure, and pick the best one for your needs

actually he's building two of the same boxes so it will be easier to put into his trunk.

Ding Ding....we have a winner :D

Only way I can cram 6^3 into the trunk of an Altima.

Got the second one built and the glue is drying. WAY too cold to take the first one out to the garage and finish sand it before staining, so it'll have to wait until tomorrow.

Impressive how many box builds are going on right now. Going to be a LOUD summer...:eek:

Naked yes, but after some stain and polyurethane it looks rather nice ;)

Well I got the new boxes in. Have a few more pics, but too lazy to upload them right now. NOT a show install, but functional.

Only played it for about 10 minutes tonight and it seems louder to the ear, but also doesn't hit as low. Which is what I was expecting. Now I just have to play a bunch of songs and see if I like it.

Boxes have to be 15+ pounds lighter each, so that's a plus as they're a LOT easier to get in/out of the trunk.

If people would quit leaving exposed edging and using 45*miters they would look much better, IMO...


oops, just gave away my secret of my newest builds :up2somet:

Here's my impression of the higher tune so far:

Definitely seems to have more punch during kick drums, but it's not as deep and doesn't seem to have as much impact as before. On some songs I really like it, but on others it seems almost hollow or lacking compared to the 30Hz tune. The sound seemed fuller before on certain songs and the subs definitely blended better with my front stage and overall I liked the sound better.

Think I'm going to yank them out tonight and lengthen the ports for a 32Hz tune. If that doesn't get me the best of both worlds then I'll go back to the original 30Hz boxes.

It's only time/testing at this point and I wanted to find out the difference of a low tuned vs high tuned box. At this point I'd have to vote for tuning for the flattest response, but I'm going to see what 32Hz will do since it's pretty much in the middle of the suggested low/high points.

Lengthened the ports and added an "L" to make the tune 32Hz and drop the size to 2.7^3. Waiting for the bondo to dry that I used on the seam where the wood is butted together.

Guess I'll know tomorrow if 32 is the magic number. I sure hope so as I'm digging the stained/poly coated BB boxes.

Bracing that is wedged/glued in place.

Forgot to order binding posts, so wire through the ports will have to do. No one will see it anyway as they're forward firing into the cabin and the opening is covered with speaker cloth.

Lining up the amp to drill holes as the board underneath it also helps to hold the boxes together.

Got a 20 minute "test" session on the way into work this morning. Seems like I found the perfect balance for these subs with this combo. Plenty loud, lots of hard hitting bass and plenty of lows.

I would have to say that 32Hz is the perfect SQL tune for the 15" RL-P now that I've tried 3 different ones.
