The idea here is to use a high grade ceiling speaker, purchased at a discount price off of an auction site, re-package it for surround sound duty. Here I used an EV C8.2. These go retail for about 350$ a pair. I have bought them on Ebay for as little as 20$ used. The EV (Electro-Voice) C8.2 is a solid, well built speaker. It has a 8 inch mid with a 1 inch titanium tweeter, it puts out a full sound with sparkling detail. But, it is made for recessed placement in a ceiling.

Most surround speakers are small, tinny devices. And over-priced. Sure, you can buy great speakers but hey , it's your money. My route is to re-purpose these for surround sound, aimed forward, not down, fill the room with sound.

Step 1: Build the boxes

The steps to build the faux speaker box are pretty straight forward.

My first plan was to build a six sided box. Fully enclosing the speaker. But this ended up being a huge 16x13 box, way to big to mount on a wall or put on a shelf. This led to the idea of a Hungarian slot shelf type thing. The speakers are kind of angled into the corner at 45* and I only have to cover up the speaker to mate it to the wall.

First build a box. I used  3/4 inch MDF. Screwed together and with wood glue too. Next , I found some Honduran Mahogany veneer sheets. I used contact cement brushed on the MDF and the veneer. Wait 20 minutes then press them together.

Its very nice &amp; informative article about <a href="http://www.clickindia.com/search.php?q=plaster+of+paris+ceiling+designs" rel="nofollow">ceiling designs</a>
This is certainly practical.&nbsp; Ceiling speakers can make rather effective surrounds.&nbsp; If you had them around, and did the above, I applaud you.<br /> <br /> However, these speakers are designed for being mounted in a ceiling (ie, in an infinite baffle) configuration, not in a box. As such, they may not sound as they are supposed to. If the engineers that designed those speakers saw this, they might face-palm.&nbsp; <em>Why not just get a full-range driver that's supposed to be mounted in a box by design?<br /> </em><br /> That said, if it works for you, do it.&nbsp; :)<br />
I don't think you have seen these speakers first hand. The EV 8.2c's are a closed system speaker, the part of the unit that extends into the ceiling is a metal box. The only port is on the front speaker side, a small bass reflex hole and the speaker is filled with BAF. I don't think the speaker is a infinite baffle type. These speakers are good enough to be aimed forward as well as downward from a ceiling. The EV 8.2c has a 8&quot; mid and a 1&quot; titanium tweeter, so it kind of qualifies as a full range speaker. My home theater employs a SVS cylinder sub-woofer for the low end.<br /> <br /> When I saw this speaker first hand, I came to the conclusion it is a metal speaker box that happens to be designed to fit in a ceiling hole for aiming down. I&nbsp;am just aiming it forward into the room, making its appearance better and making it fit efficiently better into a corner space. Also, this approach is acceptable to someone who doesn't want to or can't&nbsp; cut two ,one foot holes in a ceiling. <br /> <br /> Did you see the speakers on the last page? These box speakers together are truly great sounding, Also, the frugality of the project paid off. I picked up one pair for 40$ on Ebay. &nbsp;&nbsp; <br /> <br /> Trust me , the set up works very well for surround sound or stereo music listening.<br /> <br /> <br />
After examining the slides more closely, your'e probably right.&nbsp; Didn't know you put that much design thought into the speaker, it isn't terribly clear from the instructions.&nbsp; Most of the DIY speaker Instructables on this site consist of &quot;I put a speaker in a box and it roxors soxors!&quot; with very little thought put into the design.&nbsp; I only ran into one that tried applying traditional box speaker design theory.&nbsp; <br /> <br /> I'm glad you took box-design (or the fact that it was done for you :) ) into account.<br />
