small sub for PC speaker system

I recently built a variation on the parts express triska subwoofer.

There's more bass there than any PC speaker sub I have ever run into.

i altered the design from a 13x13x13 cube to something that worked out to about 20x10x12 externally. Internal volume was closer ot the ideal volume they stated in their DIY article online.

I'd ahve to take measurements off my cabinet, but I think you could shave an inch off the height and fit it into a rack.

Dunno if the vibrations would be bad for stuff in your racks though.

Got pictures of your hi-vi 3" MTMs? I was actually thinking of making a set of them and another of my triska mutants for my speakers in the future (or upgrade my baby HT sub to something bigger and build some PC speakers to go with it. Or posisbly for a bedroom setup).

I don't have enough posts yet to post the URL.. so PM or google parts express projects. But if you PM i can also send yo a link to a pic of the "finished" design. (I redid the speaker grills.

I'm a big fan of the Peerless XLS12 + matching PR for nearfield computer systems. Not cheap but entirely worth it.

That sounds like a great project, I can't wait to see it done. I too struggled with the constraints of PC speakers until I decided they were all junk. Now I have a pair of B&W bookshelfs, a cheap (small) Yamaha subwoofer and Onkyo receiver. Couldn't be happier.

Im in the same boat. Ive upgraded to a set of av123 xl-s and a Pioneer VSX 815k reciever. Currently deciding on a small subwoofer configuration. Ill be paying attention to your thread.

Have you considered the 8"? Or would that be to big?

I had a pair of insignias and I didnt have any isses with my PC witch was about 1.5' away.

Unless you are dropping some real money ona substantial table saw, I HIGHLY suggest getting a good cutting guide and a decent 7.25" circular saw. I chalk that up as a lesson learned that I'll happily pass on. It'll cost about the same as a cheap table saw, but will give you much more control working with big sheets, and much squarer cuts then fumbling with a big piece of wood with a short fence.

I have a 50" all-in-one clamp guide. The pro-grip guide is basically the same but a couple of bucks less.

Brian,

I will be building three mini ported subs using these Tang Band drivers one will be a dual 5.25,front firing,rear ported via one 2inch port. 28L ,30Hz tune.

Second same config,25Hz tuning.Uing dual Tang Band W6 dual drivers,1.5cu ft. 3inch flared port.

Third dual Tang Band W8,a low low 20Hz tuning,56L(2cu ft) again duals,front firing and rear ported.4 inch flared port.

I have to dig my saved winISD files,but these drivers model very very well ,considering these will be for nearfield use and not for any blasting,under one meter distance from drivers to ear level!

As little as 40W(80W sub) per woofer will provide plenty of output.

I plan to use them with a Videologic Sirocco and Sirocco Pro I have ,PC use and nearfield only.

Ok, finally have 5 posts so here goes.

the baby sub...



the project i modified for it.

http://www.partsexpress.com/projects...aSub/index.cfm

Basic dimensions are 20 high by 10 wide, by 13 deep. The front and back face are 3/4" MDF glued to 1/2" baltic birch in such a manner that the MDF is on the outside and the birch is between that and the MDF sides. Two 8.5" by 3" braces internally. Egg crate foam on the sides, top, and bottom. Red oak for the decorative panels with 1/16" black craft felt sandwiched in between. black finish is chalk baord paint applied with a roller over a sealed and primed base.

Front has the one active woofer, and there is one passive radiator up top front and back. 70W plate amp in the back on the bottom.

speaker grills have been redone with 1/4" staples rather than spray adhesive and look like factory finished parts when on now.

The sound out of this sucker is pretty surprising for an 8" sub.

raz-0,

Looking great your sub! The wood panels add a nice touch. Good work

I'd love to see one of these in a small enclosure. A 6 1/2" sub with 19mm of xmax and xbl2.

I'm sure some of the price is for using xbl2. No doubt that the db500 is more performance for the $$ but I was looking at the "small" aspect. I'd like to see a comparison with the TB also. The TB has an fs of 38 Hz whereas the Mpyre's 25.7 along with a stronger bl.
