Subwoofer make-over

[rattle_snake]

I require a big bad low end on all my audio systems, but the wife complains about the aesthetics of said equipment. Sound familiar? Well there are solutions my friends.

I build a pair of these sub cabinets and bookshelf-ish mains to replace floor standing enclosures, as I had kids on the way and the little bastards like to poke the dust caps. Paired with an Adcom 555 they light up the room well including her china cabinet. At least the speaker have some purpose unlike, well nevermind...

The subs themselves are 12" Dayton Titanic MkIIs in 2.2cu ft sealed box. I tuned the stuffing using a small signal speaker tester an have been happy with them for almost 10 years now.

So the plan was to add some aged wood to the top and bottom, but I ended up covering the whole thing and making it into an end table with a shelf. I sourced the wood from a friend, from a pile to be burned.

Before; Plain, blending in.


After a little FREE wood. I made the beer too. That's what engineers do. We make **** while most of the world is on facebook...


The business end;


Wife is now happy, which is a requirement for my happiness. For now at least. Still have to do up the other one.

Nice! Slap reclaimed wood on just about anything these days and people swoon.

Looks sharp, bet it sounds good too.

What I really like is that bird piece in the background.

Wow...that looks really nice!

 

[ovrrdrive]

Looks great!

I have one of the same speakers in a folded horn in my living room. It vibrates the sheet rock in the kitchen ceiling. lol

No hiding mine. It's a 20' folded horn.

Actually you mostly just walk around telling the world you're an engineer....

I don't see what your talking about
(just don't over water the plant...)

Thanks there were the leftovers from my gate project I happened to arrange is simialar fashion. Then they got welded up.

Nice, share I pic if you can. How did you stuff it, any recommendations?
I looking into making a pair of transmission lines using sonotubes in my shop, since space is not an issue. A 15" driver fits in a 14" sonotube, 8' long for ~28hz tune

Did you get that joke from facebook?

 

[ilovevocs]

Not too bad for an engineer.

Glad you didn't get your tie caught in your circular saw.

I know, it's so damn hot in my shop that's all I wear!

Nice sub! Mine is a Danley DTS-10. I built it in kit form.

My brother built a set of Decware's version of Jensen Imperials. It would take a barn worth of wood to hide them...but then he'd have a barn in his living room.

Actually after reading my post again I realized I have a dayton speaker but not the same one. That's what I get for drinking and posting I guess. lol

I actually have a 15" Dayton RSS390HF-4 Reference HF in mine with an Oaudio Bash 500 watt plate amp that's turned down about 3/4th of the way to keep from over extending the speaker. I bought a better speaker and amp than what the designer called for but at the time I thought this was going to just be a temporary solution and that I would end up building something else after a while. Well I never got tired of the F20 and it still sits happily in the corner of my living room. It really is a great design.

Here's the thread on it over at AVS: http://www.avsforum.com/forum/155-diy-speakers-subs/1329971-lilmike-s-cinema-f-20-a.html

And a few pics. Oh and I didn't stuff any of it. They said you didn't need to as the horn filters out all of the distortion and tunes it.

 

[flyng_fool]

Is that a tapped horn or just a folded one? I recognize it now! You're Lil'Mike!

 

[ovrrdrive]

I wish I was lil Mike... lol

Nope, I'm just a fanboy that built his on like page 30 of that thread.

This is a folded horn. It plays from a sealed enclosure.

 

[flyng_fool]

Still, that's a heck of a nice little sub.

 

[rattle_snake]

Nice those are some giant boxes.


So my @%#'n dog chewed on the new (old) wood 1st day... But hey it's free crappy old wood. I think even the dog knew that. I'm ready for the puppy phase to be over.

Nooooo! Bad dog!

Here is the other half of my system. I build these about 10 years ago when I had access to a full audio lab where I worked (company is now owned by Cirrus logic). It was a fun project. All the drivers came out of existing boxes that resembled older B&W 801s.
Mids are Peerless, tweets are Morel. I build 2nd order x-overs with foil inductors and poly caps, and adjusted with an R based on freq sweeps. These are deceptively heavy boxes. I made some beefy adjustable wall mount brackets for them, and some decent grills. They are powered by an Adcom 545. I also build an active x-over for the sub/mains, which is mounted inside an Adcom 450 preamp and stole it's power rails.

He's so sorry that he's crying!

That sub enclosure looks great!

Nah, you need to go all in and do the 12 Shivas Dancing approach. Cult of the Infinitely Baffled, and all that.

Nothing visible in the 'main' room, just a 'floor vent' ( 14" x 33" ) for the sound coming up from the 'structural' pillar in the basement holding the aforementioned 12 Shiva (no longer available, IIRC) drivers.

A quick google-fu look finds references to said subwoofer project, but not the actual page(s) themselves anymore. Sometimes, even on the internet, things aren't forever.

Ah, found it.

12 15" Shiva drivers (from Adire Audio), driven at better than 800 watts, 129 db and flat from 10-15 Hz, etc, etc.

Your sub turned into an end table is nice too. Pity about the chewing though.
