Here is my version of the RS Microbes. They have a very smooth sound to them, but you really have to turn the dial up on the volume because the SPL is a little on the low side. Once I get my sub done, I should have a fantastic 2.1 system! I glammed them up a little with a stained/waxed cherry veneer and I also waxed the front baffle. The roundover on the sides is an elliptical shape used for the tops of handrails for stairs. I really like the way they look! They are kidproof as well and my wife didn't make me make a grill for them.

Let me know if you have any questions, but except for the SPL, this is a great project!

Where'd you get that done, or do you have a router bit for it? How much? The bass is their impressive standpoint. I heard dzach's and they sounded really good!

Thanks! I did the edge on my router table - which may very well be my favorite tool. The link to the bit I used is below.
I also made up a jig to cut out the recesses for the speakers on the router table. It was a lot easier and I used a 3/4" bit, which takes out a lot more MDF on one pass than the 1/4' bit you need to use for the Jasper (I think). All it was was a 1/4 piece of scrap plywood with heavy nail poking straight up through it. I drilled a hole in the speaker center, put the nail through the hole in the baffle and turned it and I was done. I did the same on the next speaker without even turning off the router and I knew they were exactly the same.

HTH!

Dave, I would have thought you used the jasperjig. The cut-outs are right on!

Is that a 6010 handrail? : ) (I'm into stairs these days as you know)

Those look great. Yeah, the sensitivity of the woofer combined with the crossover low pass is giving you something like an 80 dB/watt sensitivity. But, my experience is that most of the time you'll get the speakers to start distorting, or at least exceed linear X-max, before the amp runs out of steam -- with a reasonable amp anyway -- so the sensitivity may not be an issue.

I'm not sure how to exactly explain this but do they sound big even though they're small? Like I guess a big soundstage?

Anyone think these would be good to use as computer speakers, with the shielded version of the RS28? Low sensitivity shouldn't matter a whole lot if the listening position is so close(nearfield is the term?).

They are fairly big to put on a desk and probably need an amp because of their sensitivity.
