If you need help linking images in Picasa let me know and I'll try to give you hand. I've been using Picasa for a while now and am somewhat handy with it.

Thanks.

I was able to link all the other pictures in the album, but for some reason that particular one kept making an error msg once linked into this board. I used the exact same procedure to link that one as the others.

I really like these enclosures, very nice work, Claus. Did I miss the details about your curved top on the new cabs? I'd love to know how you did it. Did you use multiple layers of thinner material and bend them?
Thanks alot.

The box is actually just square. The curve on the top is then shaped via hidden ribs. Like an airplace wing, then covered with a thin MDF sheet at the top. To make it rigid it's filled with foam!

Sides are cut in 45 degree angle.

All of this ensure no visible joints.

I experimented with laquer and it seemed that a 50% gloss was easy to work with and give it a prof look without being too much and also not revealing too many small errors in the veneer.

Thanks, I figured it was something like that. Any pics of the interior? I'm trying to figure out the easiest/best way to do that type of curved top, while maintaining nice tight corners and seamless joints on the outside for finishing. I'm not quite sure how to make the 2 parts connect, unless you just slap it on and maybe flush router it after?

This time around I had the cabinets delivered as they were build so cheap for me I couldnt match that price almost myself.

I'll ask him though how exactly he does it.

Small update.

Almost done with one of the new 2 boxes. Just one more sanding then the final coat.

I'm REALLY considering the LMS ultra for these 2 new boxes instead of the Maelstrom. Thoughts? on paper they will perform almost the same but the LMS will have a lower system Qtc.

Don't mind the mess in the background, only place I can laquer and make a mess without getting into trouble :)

Here's the result so far.

Thanks.

I went ahead and ordered a LMS ultra from Parts Express! They are in back order at the moment so delivery is possible not until the new year! Since I'm overseas, it'll be another 2-4 weeks. Expected arrival date is early feb! ohh the wait haha.

I'm starting off with 1 LMS and my current mael x in the other cabinet. I'll compare the two for my use in my room and see if the price difference is worth another LMS for my setup.

It models a little better in a 3 cubic feet cabinet and I'm hoping for more SQ and slightly more output from a small footprint.

That looks ace :T

What is the system Q of each driver in these boxes, and how big of a room are they going in?

The mael x in the 3 cubic feet box models to around 0.7 to 0.85 depending on the amount of polyfill. Exodus audio suggests 0.8 in this alignment.

The LMS models to be less than 0,7 even with no fill, but I'm adding "walls covered" in unibox and turns out around 0,64.

My room is around 2500 cubic feet I think. Next to it though, is a larger room only seperated by quite thin doors. So I'm not considering my space sealed off really. Also one of the doors is usually open during viewing.

Only two more months of waiting until I can finally finish my dual sub project :)

Next project is getting rid of ringing in 32 and 37 hz area!

I usually aim for a Qtc of around .675 and find that to be best. However, that is using drivers known for a good upper bass sound. That willl probably hold true for the LMS driver but from what I read the Exodus drivers arent so profound in the upper bass area, and it may well be the .7-8 is better for that driver anyway.

I cant comment from direct experience with these drivers, but my first thought is that the LMS would be better all round, it will likely sound deeper with similar upper bass punch to the Exodus and if I'm being honest, I would expect the LMS to have the better SQ from these two.

Like I say, I cant comment from experience, but based on what Ive studied, I would go with the LMS personally if I had to choose myself and budget wasnt a consideration.

Thats my understanding as well. When I planned my two subs to begin with the LMS wasnt available, and certainly not at a good price.

I'm really looking forward to getting both subs up and running and compare then. Ultimately I might end up with 2 LMS - then down the line I'm thinking to add 2 more subs for a total of 4 subs. Wife has approved it already. Lucky me!

I'm working on different finishes as well, it's a lovely hobby!

Thanks for the insights, appreciate it.

Update.

This has finally turned into an actual dual subwoofer thread!

I finished my two cabinets finally and yesterday I took delievery of 1 LMS ultra driver.

Last night I installed my current maelstrom x driver into the new cabinets. New alignment is Q around 0.8 and to be frank it sounds superb right now. I havent noticed any real loss of output but it seems tigther.

It might be in my head but I think to my self that I know this driver well enough now, that I can detect a difference.

I'm not entirely happy with my own wood veneer job. It's the first time I've worked with it. Unless they are in direct sunlight during the day and you get very close up, they seem pretty seamless and good looking. I suspect I will view them from my couch 95% of the time and from 16 feet they look just fine and you cannot notice any imperfection.

Here's a few pictures of the new cabinet and also the LMS driver which comes in a new very smart packaging.

Mx in new 3 cubic feet cabinet: (The green tape was to see excursion, I need a better looking emblem there:)



Before putting in the driver. I found some cheap pillows which turned out great. Hard to notice on the picture, but on every screwhole I mounted a 22mm plywood "brick" so that the screws grip into 44mm.



Here's one without fill and you can notice the high gloss feet plate I made for them.



LMS ultra. It really is heavy.

Too late:=)

Screws worked just fine. I've added another 22mm of plywood so screws dig into 44mm which seems to give me an extremely tight grip and fit.

I'm using the same EQ setting as usual, seemed to work out, which surprised me a bit.

It's early to comment but first impressions during music playback is that the LMS just sounds clean and full.

Mx appears to perform better in the new cabinet, atleast to my tastings. All in all quite pleased so far.

Now comes the trial and error of getting both subs up and running:)

The two subs.
