My Klipsch 2.1 computer speaker stopped working and I thought I would look at doing a DIY small speaker build. After speaking to Erich from DIY Sound Group we decided to go with the Speedsters for a few reasons size and performance were the biggest factors and not needing a sub was another.
This was my first speaker build and they are finished but I thought I would just post the process so if others are thinking of building these speakers they have a thread they can refer to.
This is what came in the with the kit. Forgot to mention the packaging was very well packed from Erich. A word of advice open the box from the bottom so all the stuffing stays in the box.
I got Matt aka
to build the cross over, as you can see his work is very clean and well worth the little extra money. Thanks Matt
Now for the building of the boxes I dry fitted prior to gluing the box together and everything was a perfect fit. Prior to gluing I installed the criss overs, just a FYI attach them to the bottom panel to the very back right hand side leaving no less than 1/2” from the side and back. The reason for this position is the magnet on the sub will hit the cross over if you put it anywhere else. I glued all 4 side to the back panel using gorilla glue and clamps. Just a note don’t do what I did and put the poly stuffing in first like I did it just gets in the way.
I left the box over night with the clamps on, once I removed the clamps I installed the front baffle, sorry forgot take pictures of the process but pretty simple applied clue to the top of all for sides and placed the front in and clamped.
Once dried I took my orbital sander and cleaned up the boxes of any excessive glue and deficiencies in my wood working skills. Used some spackle along all the edges just to hide the seams. Sanded and primed with a spray paint primer in a grey colour. Again sorry no pictures of thank process, newbie mistake not thinking of pictures taking during the process.
I put poly stuffing in the cabinet to cover the to speaker opening so when spray painting I wouldn’t get the paint on the cross over, you can cover the holes how ever you like but I’m just suggesting if you are spraying your speakers don’t get paint in the cross overs.
Once the I finished spraying the speakers, 5 light layers I drilled 2 small holes for the speaker binding posts. Here a small word of advise if you don’t have them just get them off Erich, I bought mine off amazon and the all look the same but the ones I got were very short which made it a pain in neck to attach the nut to the binding post inside the speaker.
As per attaching the speaker wiring to the binding posts and the speakers you can either solder them or use wire connectors both will work just fine, I soldered them.
The wire you attach to the binding post from the XO is the the one mark “IN” on the XO. After that was done I attached the port on the back using a 1/8” bit to drill pilot holes to make it easier to put the screws in. Once that was done attach the wires to the ribbon tweeter marked “HF” on the XO and sub wires marked “LF” on the XO. Once that is done I took the poly fill and filled the cavity without blocking the port and the back of the woofer as seen in the picture.
Put the speakers in place having the speaker on its back. I may have a little OCD because I need to have the screw holes on the speaker perfectly horizontal so I used a small speed square and put it on the bottom of the speaker and then turned the woofer to aligned the two holes of the woofer on the right side to the edge of the square. Did the same for the ribbon tweeter but put the square at the top edge. Then I drilled a 1/8” pilot hole for each hole prior to putting the screws in. Be careful that you don’t slip and put your driver through the speaker so go slow and maybe protect the speaker with you hand as you screw it down.
Here are the finished speaker in the pictures below.
I powered these with a small little amp with only 15w per channel as you can see it in the last picture just below the computer screen. I thought 15w would be enough but man they go loud enough but you could go with more if you like.
I’ve had these hooked up for about 4 days and man they are an awesome speaker. They fill my main floor which is about 1500sqft with ease, again only 15w. The ribbon tweeter is amazing, so clear, the detail of sound is incredible and that little 4” woofer puts out some serious bass for what it is. I don’t think I need a separate woofer, it’s a perfect blend when listening to music. As per movies I didn’t watch one but watch some trailers and man there is no comparison to the Klipsch, I felt so immersed while watching the new Star Wars trailer the voices were so clear and the action scenes were awesome. So if you are in the fence I hope this build helped you make your decision and if you bought the speakers I hoped it helped you with your build.
