The SS website says 35.5 cm. What size diameter is that in "english"?

Thanks! But it only comes to 5.5 inches? That's the driver hole? I think it's too small.

Ok. What size cutout should I make for this driver?

Thanks

You sure? My front baffle is 25" cube and I measured from center 14" and it was huge! The driver will fall through.

Come to think of it. I think it's 7" from center. Right?

13.9 but 14 is just fine. Be careful not to over-do, you can always sand.

EDIT> 7" from the middle is 14" but you need to account for the router bit. (keep it on the inside of your mark) You might want to do a test cut first on a piece of scrap.. so your confident in your cut?

Hey Steve,

Yeah, I cut a 6" port hole with a jig saw and worked fine. Like you said, keep it IN the line.
So, 7" from center.

Alright!

Yip, but be sure to double check things in a couple ways before you make your actual cut. If your a 1/16 off on each side, that adds up when you don't have a lot of meat to play with.

I'll go slightly smaller, like 6-3/4". And I'll trim if I need to.

That's a idea.. I understand where your coming from, but that can complicate things. Just measure and re-check at it's widest, then go for 14" or a 1/32 under on each side. You'll be fine Vito

13.976 inches, but it looks as though steve nn pointed that out and all is well under way.

No, you da man!

Today I pinpointed the center of the baffle and placed a nail. I then took a measuring tape from the nail and went just slightly below 7". Came out well considering I'm using a jig saw for the first time.
I'm taking pics and when I have it together, I'll post them all.

I have some pics.

I ordered two pre cut 9cuft cabinets and started assembly.

This is the cross panel to hold the braces as you will see.


Side brace. I made extra holes to add alittle more volume.


This the combo baffle/rear brace.


I made 6" port hole using a jig saw for a 24" PVC.


Front and rear panels/brace glued and clamped.

Side braces and panels in place.



Port checked for fit.


Both boxes almost done.


Cut the driver hole.


Oh yes! It fits!



I have to stop until next time. I'll post the updates as they come.

Where did you order those? Did you do the design? It looks very good.
What thichness do you use?The round cut with the jig looks good too. Any tip you can give us how you did it? how many teeth per inch on the blade?

Please keep posting pictures. This is really helpful

(love the bike too!)

Between the two of them your looking at 18 cubes, heck that's rather largish in my book Your also well under 20 Hz tuning at 17.

Your right! They are rather large, but you know the way things are. Never satisfied!

My only dilema is what finish. I can't use spray paint because they're very heavy to just move around and second it's cold outside therefore I have to finish inside. Being MDF, it's going to suck up alot of primer. I'm thinking speaker carpet, vinyl, etc.

I went here. http://cls.audiogon.com/cgi-bin/cls....ubw&1173777422

They're 1" thick MDF.

For the driver hole I took anything straight and lined it up diagonaly corner to corner and drew a line. Do the same on the other side. The two lines meet at the center of the baffle. That's dead center. I then hammered a nail on the dead center and grabbed a measuring tape and placed the tape's lip on the nail and then measured 7". At the 7" mark I had a pencil and began outlining the circle while maintaning the tape straight and holding the tape on the nail with the other hand.
When the circle is made, I drilled a 1/2" hole on the INSIDE of the circle and placed the jig in the hole and began to cut. The blade is a standard jig blade. Don't know what size and how many teeth. But worked great!
I hope I'm clear otherwise I'll take some pics next time and post them.
