I just had someone do it at a local place. A professional came make the difference in upholstery. Though I'm not sure what you mean by a shell unless you're thinking of building a box that would slide over the woofer, which would worry me about vibration noise.

That is what I meant, and I agree I think that might open a can of worms.

 

pgwalsh what does your response look like, and what kind of output?

Well that should only be an issue if you want that tufted look, but there may be some ways around it. The stitched leather or pipped leather look is not an issue.

That's cool, I would probably go with stitched leather.  This project will be a ways out if I consider it....I don't even have my brand new dual subs broken in yet or dialed in completely lol.

Cool... I have 2 dual opposed paired with mine, but will eventually remove them as I'm trying to clean up the room. That being said, I know have a bug to do another one, but with 6 inch leather sides and either wood, marble or granite inlay in the middle.

I dont know about a standard height but I would use 18" as a guide. That being said with padding, legs and around 10" or more for depth of woofer we are already at that. So I guess its a matter of how much padding you really need. Although if the center of the ottoman has a marble area then you can gain some volume back there while the outside edges are all padded.


Does this make any sense?

I had been thinking about doing one myself but with dual 15's. I just dont have room for subs anywhere else.

There is a standard height, I'll have to look it up. Super tired as I just drove 1500 miles in a Penske truck that had a governor. I could get past 40 over the sierra's.

Because I keep thinking about doing an ottoman now, how much height did the upholstery add?

And did you ever get a chance to get a picture of the wiring?

I thought about using some large flat/wide speaker wire if I built one.

sorry for the late response, I was out of town.

I designed the box with the upholstery in mind. I used a higher density foam that's not quite as thick. It's not as cushiony as some, but soft enough to be comfortable. If your box isn't as high you can use thicker foam or thick and thin foam to make is plush.

It's just wired like any other sub. The hookup is on the bottom.

That sounds like a good idea. If you're running it on hard floor then you'll want one of those wire protectors you lay over it. If you can get under the floor you could run it below and up through. A good idea is to make it quite heavy so people aren't attempted to move it to suit their needs.

Hey pg, did you ever take measurements of the Ottosub?
I think I read that you ended up finding a working 21" Maelstrom, that's good to hear, how is it holding up?
Still one of the coolest WAF builds around here.

Cheers

Hey thanks for the compliment.

I found a working driver, but I haven't taken measurements. I suppose I could because I have all the equipment. The problem right now is that the room it's in vibrates like a 757 2' over your house. I'm going to be building a theater room, but it'll have a different sub arrangement. The ottoman will stay in media/bar room. However when I build the room and put the sound treatments in, I can take that sub in and do some measurements.

Thanks again for the compliments. Oh and no one ever realizes it's a sub, even when they're sitting on the couch watching a movie.

This is fantastic! That upholstery work coupled with the excellent choice in stain (even if it was something of a PITA), really looks professional.

At the risk of becoming a parrot, we'd love to see measurements if you're able and willing!

How heavy did this beast end up being?

It'll be a few months before measurements. I know I promised them in the past, but I moved, got married, had a kid and then had 2 deaths in the family. Things happen.

If I recall correctly it weighs 178lbs.

No problem, that's totally understandable. Sorry to hear about your losses, but congratulations on the other events!

Any other projects in the future? I'm sure you've got some sort of the DIY fever that everyone on this website seems to have.

Thanks!

Yes.. I'll be building 4 x 18 Dayton subs and a theater room with some concentric 8's. Still in the design faze.

Cheers
