Here are some pictures of my latest build. I was going to wait until I had completely finished them, but I am still undecided on which way to go. This is my second speaker build and my first single driver. You can see my first build here :First build: X-LS mini-monitor
Thanks to Bigun for sharing his Martello plans. I am really enjoying the speakers and I would have to say they have exceeded my expectations. I probably have 150 hours on them right now. I am listening to them nearfield on my desk and the soundstage is really good.

I have not glued the backs yet. Waiting to see if I need to add anything. I lined the inside of the speaker with several layers of wool felt. I may need another layer. We will see. Speakers are constructed from 1/2" BB plywood. CNC cut by a local cabinet shop.

And finally the finished pictures. I found some walnut veneer on Craigslist for cheap so I got it. I used the iron on method and some wood softener. It worked pretty good good, but I bid have a few splits.

Thanks, I found some 1/8" panel board at Lowes to make the grills. I actually cut away a lot more if it than the round hole you see in the pictures. I forgot to take a picture before I added the grill cloth.What did you make the frame of the grill out of? Oh wait, those are the grills in post 5... ok...

So, how do they sound.
They sound a lot better than such a small driver and box has any right to.
I have a pair of fr88ex in 2,5l ported tuned to 70Hz. I have tested many options but found that they sound better with the notch. I'm using 15uF, .22mH, 4.7ohm which makes a bit narrower (more Q) notch than that posted above, but it's still centered at 2700Hz.
If you use them as desktop speakers, BSC is not absolutely necessary, but I have had best results with about 2dB BSC.
