Just some pics for comments. I started this project 2 days ago after receiving a pair of 10F3 Fostex drivers I won on eBay. Scrolling arounf the net I found a design that has much in common (at least looks) with the beloved Fonken speakers so I just had to build a pair. I am in the process of veneering them now and should have the final product by tomorrow. I will be trying a filter with these that includes a 10R, 0.9mH, and 4.7uF all in series.

Jeff,
The Solo 103s was one of the inspirations for the original miniOnken... that and an Onken design in a late 70s Audax design guide.

Dave,
I am wanting to know what your thoughts are on wood type to use for these types of projects we have been discussing on the various threads. My local lumber yard carries tree types of veneer ply (oak, maple, and birch) The Oak and Maple are 5 ply whereas the Birch is 9 ply. They also carry 1/2 baltic birch which is 12 ply and the 3/4" can be ordered. The Oak and Maple seem to have the lowest voids and also seem to be the densest.
Which of these is the best for the Metronomes, Fonken, and other similar designs? Prices are very similar with the exception being the Baltic birch, seems a bit more expensive per sqft.
