I was a little nervous taking the pictures with 107lbs sitting on that stand.

God Almighty!

This has been a great thread to follow. Excellent work.
post #306 of 732
It's lookin' good. When do you think you might get some test tones through it?
post #307 of 732
I want measurements
post #308 of 732
haha....thats is just too funny. That driver is sooo massive. The enclosure looks big until you put that driver in it.

So when do we get to see the sub punching that speed bag?

still some work to do yet guys. Put the binding posts in and wired, get it sprayed with lacquer, get a granite top plate cut, finished and installed.

wow that thing is just plain massive. i can imagine your grille to be pretty massive as well considering it looks like it is already protruding out quite a bit.
post #311 of 732
I'm just going to go ahead and vote this the coolest thing ever - it's looking fantastic so far

You're the first one to mention the surface mount. There is a design reason for it. More on that to come later.

i'm pretty sure it has to do with the way that your layers are glued together. i wouldn't take any risks at getting something snapped or broken.

Kinda gives me a sense of seeing a rapper's Escalade with 24" wheels! The scale is skewed toward unbelievable!!!
post #315 of 732
Wow Looking good Corock, not long to go now..

Is it just the angle that you shot your pic at, When looking at the 21" driver installed in the Cabnet it looks as if it isn't centered in the baffle on the horizontal plane.. On the left hand side it is closer to the magnet compared to the right...

Cheers..

That isn't the reason I did it surface mount, but that is a good point for anyone else who does a translam build like this. I did my first cut, the outer most ring, with a small 1/4" bit. It made a clean cut with no chipping or flaking of the plys. But I could see the possibility of part of a ply breaking off as the bit moves parallel with the layers. As I cut the inner rings with the 1/2" bit, and no outside support for the plys, pieces would break off in chunks near the top and bottom where the bit was moving parallel with the plys.

I noticed that too and I'm not sure because I've taken the driver out now. I gave myself a slap to the head though because I made sure it was centered vertically. When I saw the pictures I realized I didn't check the horizontal plane. Thankfully I only have two bolt holes drilled.

GP measurements can be done before the finish

I agree, I was looking at all sorts of different options when I was shopping for feet.... ended up with the Paradigm feet as well, but I did see these and thought they looked really sharp, but the price point was a bit outlandish... Totem Claw



Maybe some 3" bar stock machined would provide a better size ratio for that box..
post #320 of 732
At least you can re adjust it, Just rotate the sub A little..

I know with me I tend to get impatient towards the end of A build due to being so keen to get it up and running, but all good things take time and cant be rushed, its the small details of your project that tend to be the iceing on the cake so it pays off in the end..

Cheers Bro..
post #321 of 732
I think the consensus would probably be that we are all a bunch of impatient F@#k's around here. I know I would wire that beast up tonight and run it through it's paces this weekend before the final finish.

Your doing the right thing to wait though. Geez......I am getting antsy just thinking about that beast being fired up. You have some Iron Will there corock.
post #322 of 732
What are you thinking for a grill? I'm in need of some grills for 21's too and I'm having trouble deciding on which way to go.

I'm not putting a "grill" on it persay. At least not right away. Initially the front finish will leave the cone exposed. That's the plan anyway. Right now its just in my head, so I still have to see if what I have in my head works in real life.

That box looks tiny compared to that driver. Wow.

I think something along the lines of a slightly curved black mesh metal grill would actually be really cool, especially with the granite top. I'm not sure something cloth would really go with the whole theme ya know? Just seems a bit too soft and cuddly.

You could cut come neoprene pucks about 1.5 inches sqare for each corner this would decouple your sub from the floor. Use the ones for folating floor in recording studios.

They are flat on one side and have ribs on the other and are about 1/2 inches thick.

For maximal insulation with this stuff is to have near 20% compression (not more)from the neoprene so it will act as a "spring"
post #328 of 732
For feet how about thick granite pucks.

Warp,

If I may ask, where did you find those Paradigm feet at? Thanks.

I'm not going to knock myself out over the feet. I don't think I'm going to go with anything outside the enclosure, the scale is just too large. I just need something underneath so that I have clearance to allow for speaker connections on the bottom. As well, the sub is going to be on carpet, so the feet are pretty much going to disappear. I think I'll stay with a simple carbon fibre puck for feet.
