Ml Sub Sealed--pics!

After completed the ported ML sub project which was a total shot in the dark and mostly for fun, I built this sealed version.

My results initially are very good. I am getting good controlled response and so far have no complaints. More to follow.

The box is MDF 1 1/2 inches thick all the way around. The internal volume is exactly 1 cubic foot minus what ever volume the actual speaker consumes.

I still have some dressings to complete, but I love to "hear" what I have built before I "see" it. I just cannot wait!! I will probably try veneering since it went so well for IWalker.

You will also notice my totally completed ported version in the pics too.

Does that box just have 1 of the drivers? I like it! Nice and overbuilt! Good luck with the veneer. Feel free to PM me if you have questions regarding how I did it.

So you're happier with this than with the ported version, I take it?

I am much happier with this one. I have yet to play a dvd though to see if it holds up for some true movie bass.

By the way IWalker, I was inspired to "overbuild" this from seeing your box.

Pics with the cherry veneer installed. I have'nt decided yet if I am going to stain it. If I do-I will try to match it to the ML Descent cherry top.

Very nice! I think it's beautiful! I'm certainly very happy with the stain job that I got on the cherry, but rub the veneer with some mineral spirits (to clean it) and look at the color you get out of that...it's gorgeous in it's own right. It'll be quite hard to stain "match," though you can take small strips of veneer and try different stains on them to see which one comes out how you like. My thoughts on overbuilding....Why Not???

I agree witht the overbuilding comment IWalker. I could have added some bracing inside as well-but baby steps...right?

As a completed project, I am very happy with this sub. Although I had thought initially that it was very close to air tight, some interior caulking on the inside edges has proven to make a significant imporovement on overall tightness/clarity of the sub. It turned out so good sonically that I will probably build another identical and run them in parallel.

The hardest part was finishing the veneer on the edges. IWalker, how did you ensure very clean cut edges? My edges look perfect from about 10 or so feet away, but there are some discrepencies which are annoyingly apparent to me!
By the way-I found that the best tool for the edges was an old cutco sandwhich blade I had. Maybe some of you know what I am talking about?

There's a router bit for just that purpose. After that, take some fairly high grit sand paper and sand it down to flush.

Son of a.....What is the name of the router bit? Perhaps you could attach a link to one similar to yours?

Now I have to start all over and redo it!lol

Thanks,
Dominick

Haha, it's called a "flush trim" bit...go figure, right? It has a bearing that runs along the edge of the surface below the veneer...and the blade trims flush to that wheel/bearing.

you can get them from lowes, etc.

Are we connected with Lowe's Racing or just like the store?


On the flush trim bit.

Be sure to keep the bearing clean and lubed with Teflon type product that will not stain or leave residue on the veneer.

It doesn't take much gunk in the bearing to stop it from turning and it leaves an unrepairable burn or dent in the wood which in turn will make your stomach not feel good when you see what happen. I have had mine turn over a couple of times.

Yea, I generally prefer Lowes to HD too...

I'm building a 5000 sq ft building on our property right now with most of the material coming from them.

Glad to know some of the money I am spending is going to your audio purchases.
