The tube was placed on the freezer for a better work height:

(I think it's cute)

The top endcap goes about 50mm into the tube, so the foam is placed accordingly:


What's all this talk about glue? These things don't move even without glue:


Using some contact cement in the corners anyway:

(better safe than sorry)

One tube finished:


Nope, not the other one unfortunately. It's the same from another angle...:


One tube to go. Then glue on some carpet and only the assembly is left.

Thanks!

I can't wait either, although I have to admit that I have few references when it comes to really good subs, so I don't know exactly how I shall judge/compare it...

I was in the same situation. I think you'll find that from now on, you'll be spoiled. Friends will be blown away and you will think, "Man, is there any other way to do it?". Now I don't mean that as far as alignment is concerned, but rather DIY vs Commercial.

I too , await your final finished pics and impressions. I forgot, did you break in the drivers some?

I did some light break in in free air for about 40 hours or so, but I don't know if it had any real effect...

Here's some pictures of the carpet that I'll use to dress my tubes:







I guess it's what's called "automotive carpet" or something similar. It consists of two parts. One 2mm hard (grey) part and one 3mm softer (black) part.

That is PERFECT carpeting for subs. Where can I get stuff like that??

I have no friggin idea where to get it in the States... it was bought in a more-or-less normal carpet shop (who also sells paint etc.).

Time to make some speaker cables!
(sorry about the bad pics! My wife run off with my camera this weekend, so I had to use the cell phone camera...)


Speakon in both ends so that they plug into both the amp and the subs:


The Speakon conenctor supports max 4 sq mm cables, so I had to take away a few strands:


On with the heat-shrinkable tubings:


The finished product - two 8 meter cables:


Why 8 meters? It's for the HTF thing. We're using quite a large room and don't know the exact posision of the subs.

The base plates was actually more or less done (except for the painting), but then the mirror idea came up, and I had to make some adjustments.

Instead of recessing the mirrors, I "built up" the rest of the base plate with a 5mm thick (same as mirror) material:

(here I'm using the router to cut them out)

Here's how the baseplate sans mirror will look like:


The old story about the glue and the clamps:


I was stupid enough to round both the upper and lower edge of the base plates. The upper edge should never have been rounded, because when I added the 5mm material I got a groove that had to be filled:

(a bit strange focus, but I'm trying to show the profile)

First one round with two component filler (because the usual one shrinks a little):


Then one round with normal filler:


Ah! Finally I could do the routing and make the rounding that was intended in the first place:

It's from a Sony Ericsson W810i. It's the standard 2 mpix camera that is in half of the SE phones I think...

I guess they're allright... Would've been better if I could have attached it properly to a tripod, though...

To get the most out of the cell phone camera, the same rules apply as with the pocket camera:

1. Use tripod
2. Don't use flash

On the cell phone camera menu I used the "nigh mode" which means that it uses a long exposure time instead of a flash. In addition it actually had a macro mode (nice for those close-ups). Due to the long exposure time it was a must to hold the cell phone still for a few seconds. I rested it on the top of the tripod, but was unable to attach it.

Hehe - I'll swap it for your subs ;-)

Maybe your pics are fuzzy, but at least you consentrate on finishing your subs instead of messing around taking the best possible pictures...

Keep up the good work!

I think it's called huntonit or something. It's coarse on one side and smooth on the other. I have no idea how it'll finish. I'm not worried though, as the bottom plate is an easy part to replace if the finish turns out to be a disaster

I'm about ready for carpeting the tubes now. But first I have a job to do in my work room.

Behold da mess:

(to put it this way: I'm not walking around here barefoot )

I have to clean this incredible mess up, before I can start wrapping the carpet around the tubes (by lying the carpet on the floor and rolling the tube over it).

Wish me good luck...

Damn Rune, it's going to take you another week to clean up that mess!

Actually, I had noticed that your shop was getting a bit cluttered in one of the more recent pics. My woodshop doubles as a garage. Consequently I'm regularly dusting off my sons bike and helmet before he goes for a ride.

Good to see your on the home stretch. Keep it up. Looking forward to the final pics and first impressions.

Remember... no matter where you go, there you are.

Nah... much was done in one night:


I think the MDF dust alone amounted to two whole plastic sacks. I think I've done 35 rounds with the router per sub (and that's not counting multiple passes and extra rounds because of errors).

Is it any wonder there's some dust?

Plastic on the floor makes it clean enough:


First I cut the 200 x 306 cm carpet in two:


Then I rolled it around one tube to align it properly:


Then I gently pulled back a piece of carpet and sprayed it ,and the corresponding part of the tube, with glue:


Note that I left a 15cm gap against the end of the carpet. After 15-20 minutes I rolled the tube over the glued part and then the direction of the tube/carpet was locked.

Then it's only a matter of glueing the rest (almost)...:


...and roll on:


As I wrote before, I've left 15 cm towards the carpet joint unglued. This is to be able to "double-cut" them (to make a nice joint).

So what are you going to use as backwall when doing the doublecut so as to not cut through the tube?

Good question, ssabripo! The best would undoubtedly have been some kind of thin sheet of metal (thin to not make the carpet ends too long and of metal so you don't cut through it).

I'm not sure how to obtain such a piece of metal, so I think I'll settle for something called "rettepapp" - well it's called "rettepapp" in Norway anyway...

I haven't the faintest idea what it's called in English, but it's basically precut cardboard strips used in construction to get those last two millimeters right. I have used it a lot when refurbishing my home (to get some walls straight(er)).

The strips are about 2 x 1000 x 50 (or 1 x 1000 x 50) millimeters, and even if they certainly are not "cut proof", I'll think a couple of those taped together lengthwise should do the trick.

What do you think?

Sherv/Rune - I found that with a good really sharp blade, one doesn't have to worry about doing much of anything to the tube. It is much stiffer/stronger than the carpet.

Or you can use a hook blade, like this:

I did mine like willy, change the blade three or four times if you have to and just take your time. A good straight edge to work of off would be nice too.

I'll take your word for it, but I haven't got my lazy ass to a store that has this kind of blade yet...

I keep imaging that if you use a hook blade (and have to change blade 2-3 times for one length of double-cut), the cut must become rough/edgy?

But again, since I don't have a hook blade and I'm dying to get the sub done, I'll try with the standard (stanley?) knife cut approach.

Then you two can do the what-did-I-say-routine when I fail miserably

BTW: I envy your metal ruler! Looks really nice for that purpose. I'll have to use a "long water" to do the same.

More importantly, you just want a really sharp blade.

You guys...

Well, I've done one tube, with mixed luck I'll have to say. But it turned out OK in the end (I think). I'll write more about it tomorrow (with some pics).

Mine came out good but still not perfect. Anyway the good thing is that is on the back. Even if it was on the front with that type of carpet i'm sure it wouldn't be to noticable from a couple feet away.
