Turn broken speakers into a snappy media cabinet

Picture of Turn broken speakers into a snappy media cabinet
Broken speakers are pretty but useless, media cabinets are ugly but useful, a synergistic melding of the two objects was all but inevitable.

All you'll need to do this project is:

1. One (or two) old free standing speakers, the bigger the better. Preferably in good aesthetic condition, preferably broken, and preferably free (I gave myself a $20 spending limit for mine).

2. A hand saw

3. Some hinges

4. A claw hammer or crowbar

5. Some paint

6. Planks of wood (to make shelves)

7. Screwdriver or a power drill

8. Roughly 2.5 liters of pure, unadulterated gumption. Feel free to replace with true grit.

I also used a rotary tool, but I'm sure you could pull this project off without one.

Step 1: Disassembly

Picture of Disassembly
In order to keep the actual speakers (which are usually really fragile) out of harm's way while doing this project, you first need to get them out of the speaker cabinet. Typically this will just require you to unscrew a few phillips screws, then yank on some wires until the speaker breaks free. This is what we in the business call "the easy step".

Step 2: Disassembly (cont)

Picture of Disassembly (cont)
All speakers have enormous magnets stuck to the back of them that would absolutely wreak havoc on any DVDs, cds, or video games that you put in your cabinet, so those have gotta go (in the first picture, the magnets are the two black rings at the top of the speaker cone, though most speakers only have 1 magnet on them).

Fortunately, these are usually only held on by some small metal pins and a lot of glue (as you can see in the second photo), so they're pretty easy to get off. Just take a crowbar or a chisel and hammer it a ways down into the seam between the speaker cone and the magnets, then pull it out and repeat that action around the full circle of the magnet until it eventually pops off (once you get the hang of it each one should only take you 30 seconds or so, unless the speakers are really tough).

Once you've removed the magnets from all of your speakers, wallow in the delicious scent of self satisfaction before returning to work. It's now time to focus our work on the cabinet.

Step 3: Cutting a door

Picture of Cutting a door
There's a million (well, maybe not a million, but at least 7) different ways to cut a door out of a speaker box, so you don't have to do this the way I did. That said, one thing that you must do when working on this step is make sure that the door you cut out of your cabinet does not touch the ground. You want it to cut through the front face of the speaker box so that the door won't drag across the foor when you open and close it, but at the same time you want the cut to be inconspicuous enough that your end product will come out looking like a media cabinet disguised as a speaker, not a former speaker that you clearly butchered the bejesus out of for seemingly no reason. This can be a little tricky, but with some patience anyone should be able to pull it off.

First measure out and mark the lines of your cuts, then make those cuts. To make the awkward cuts on the side of my speaker box I first took a rotary tool and cut a groove into the lines where I was going to make my cuts (pictured), then took a hand saw and finished those cuts. You could probably use a jigsaw or a circular saw to accomplish this same end, but I'm not very good with those tools, so I took the old fashioned route.

Step 4: Internal clean up

Picture of Internal clean up
Once you make your cuts, your speaker should be in two clean cut pieces as is pictured here (yours probably won't look nearly as good as mine, but whose fault is that? Hmm??)

Speaker boxes are held together with goopy epoxy-like glues and their insides are never intended to be viewed by anyone, so you'll probably find a lot of glue globs and what not stuck to the box's inner side walls. Take a chisel or knife or whatever and scrape that stuff off, and get rid of any other stuff you might find in there while you're at it (for structural stability purposes, a lot of speakers have little wooden blocks glued into their corners on the inside).

If any chunks of wood have come out with the glue globs, or if you had a missed cut or two when you were slicing out your door, fill in those errors with either some wood filler or some epoxy putty (I recommend J&B Waterweld, as it's the best stuff on the market). After that, sand the inside of your box until you're pleased with its overall smoothness. For the record, I was chasing after Billy Dee Williams level smoothness, so I had to sand mine for a LONG time.

Step 5: Paint 'n stuff

Picture of Paint 'n stuff
If you want to have shelves in your cabinet, secure those into place wherever you want them. The side walls on speakers are usually too thin to effectively use wood screws on, so if you're going to hold your speakers up with L brackets you'll need to either use nuts and bolts or some epoxy putty to hold them in place (I went with the epoxy putty, as you can see from the white globs beneath each of my shelves). Then again, you could just run some wood screws from the outside of the speaker box directly into the sides of your shelves, but I didn't think of that while I was doing the project, so I went with plan A (which, admittedly, probably should have been plan B).

Once everything structural is in place, lay on a couple coats of paint (unless you want to showcase the gorgeous particle board on the inside of your cabinet). I won't tell you how to properly administer paint, as anyone who doesn't know how to do that almost certainly wouldn't know how to read either.

Step 6: Hinges and Sexiness

Picture of Hinges and Sexiness
Get out your hinges and carefully affix those things to your speaker box and speaker's front panel, so that it can swing in a door-like fashion. This door-like swinging object will henceforth function as your door. It might also be a good idea to attach some sort of handle to the front of your cabinet, so that opening it won't require 4 inch long fingernails.

Once that's done, you're free to stand your new kickass media cabinet up and see how it works. If you did everything correctly, your new media stand should be the envy of every Tom, Dick, and Harry within a 10 mile radius of your living room (though I won't be envious at all, as I already have my own speaker media cabinet... also, my name is not Tom, Dick, or Harry).

I'll hopefully be porting a lot of these projects of mine over to instructables in the coming weeks, but not all of them, so if you want to see some of my other stuff please check out: My Drivelicious Blog

Lose the handle and you've got a great place to hide larger valuables. No one's gonna tote around a giant speaker from the 80s if you get robbed!

What a great idea! I may try this, now!
LinuxH4x0r7 years ago
Nice! I might do the same thing, except I would keep all the a/v equipment in there instead
this is beautiful! I found exactly ONE big ass speaker in my old apartment's basement. What the hell do you do with ONE giant tower speaker? The cones are all busted on that one too, I am totally gonna try this out! Genius!
If it is a tower, than it probably has 2 or more inside
ah that is quite clever! Here's the speaker, the text on it says MCS Series 683-8857 can't find any info on it online but can you see two speakers out of this? Probably just a decent sub and maybe a center channel with the mid and high? Don't know much about speaker building I will admit, but I would love to learn more!
teeps teeps7 years ago
i hope the image shows up, seems to be broken, if it doesn't, it has two 12" subs and a mid and a high
Tumunga teeps2 years ago
you might want to check those. I believe one of them is passive, which just looks like a speaker. At least that's what I remember from the set I used to own about 15 years ago.
Nice, you just scored 2 subs.
that bottom sub, the middle is all punched in. Does it still have hope? Where are good resources for the job of rescuing those subs and making a new home for them...?

Instructables: How to "unpop" a speaker

Never tried any of these methods, but they seem like sound advice.
Nice looking speaker by the way. Try repairing it first?!
Even so, this is a damn good idea GoodRubbish
they do work, exept the "sucking" one
All it is is the dust cap, you are fine.
GoodRubbish (author)  teeps7 years ago
I've done a lot of these speaker mod projects, and I've yet to encounter a speaker that didn't have its center bubble thing punched in... I think people are naturally attracted to smush them inwards for whatever reason. Regardless, if you end up not being interested in using the subs as actual speakers (and thereby decide to take the magnets off the back of the speakers) you'll be able to easily reach inside the speaker cone and push that center bubble back out to where it's supposed to be with a pen or a q-tip or, if you're not into tools, your finger.
It should still work. Try popping it back up with a needle, or maybe a really small straightened fishing hook

Very cool
Mattkguns7 years ago
Im fairly certain that magnets don't affect plastic media, ie any thing on a cd or dvd. they will however affect vhs's and the like, so if your only building the cabinet for dvds, then you'd be safe leaving the magnets in.
yeah, magnets are no threat to optical media. It's just magnetic tape and disk media that you need to be careful with.
what you do need to realise the layer on the top of a cd/dvd is metallic

Magnets DO play havoc on video CRT's.

But really, breaking off the magnets off the voice coils of those old cool woofers is a waste. Those should be re-foamed and mounted in new better designed enclosures for really cool low frequency effects. Don't destroy them.

If you think those magnets are cool, you break into your hard drive and check those puppies out!

Great instructable, but next time you have some fishers, techniques, pioneer, sansui ect. please don't hurt them even if they are broken cos i love vintage speakers!
i meant technics lol
tmad40blue5 years ago
It makes me cringe to see how you ruined these perfectly fixable speakers, and how many people have followed in your path. These speakers, along with the other ones that many people on this comment thread have most likely destroyed, could have been fixed up by knowledgeable people and put to good use as SPEAKERS - not gutted and made into dumb decorations. I hope you feel proud - an entire thread on Audio Karma is looking at all of you in shame. http://www.audiokarma.org/forums/showthread.php?t=249492
 Not nice!
even your friends on AK agree that these were garbage to begin with.  Next time, do us all a favor and leave your douchebaggery at the door.

No. Those were lowly Fisher STV-6XX model or similar. They probably are better off as make-shift shelves TBH. Plus you can always recycle the bass drivers and re-use them as subs in a uber-cheapo car system. Best thing for those tweeters is just to meet mr. trashcan.

Really? Seriously? There's an entire instructable devoted to making you guys feel awful then, for being so offended by something this innocuous.

Excellent instructable, GoodRubbish!
I'd kill to have those cabinets to mount some big Audio Nirvana full rangers in. No crossovers required.
I love it! Fantastic job! Those are some nice speakers by the way... It definitely warrants a trip to goodwill!
haha i just went to goodwill and got some huge ones for exactly this! only i didnt know anyones already done it!
They'd probably look just as cool to keep the screens on them

Briliant! lol I love the idea PS Great instructable! Thank you!
those are great speaker cabinets !
I like how you assembled your own shelves.
Great Idea !

these are mine.
Robber comes in expecting to steal valuable speakers. Comes out with stacks of DVDs, CDs and a bunch of spare wood ;)
I'd still be rather bummed if a robber stole my CDs and DVDs to be honest =P

I have a question....where would i buy these type of big speakers? My city is having a garbage day soon and i was wondering if i could find any on the street or anything....or would it be in a thrift store for way cheap? because i tryed ebay and that was wayyyyyyyyyyyy expensive. Thanks!
GoodRubbish (author)  Darkshot6 years ago
Craigslist is your friend on this one. Your best search prompt for great deals is going to be "broken speakers", as nonworking units really have no practical purpose to the general public anymore. After that just search for "big speakers", "large speakers", "standing speakers", or "floor speakers" and put the max price at like 30 bucks or something. If you find an old listing on there that hasn't sold yet you can usually talk the seller down to practically giving them away.
cool, thanks!

Really sweet build actually. I have an old pair of Fischer STV-649s too. Unfortunately mine still work and there's no way I'm going to sacrifice them for media cabinets. For that matter I have a set of STV-666s too.... Great sound on the cheap if your into old school equipment.
