My Iron Driver entry was a 2-way designed around the SB19 iron driver tweeter and Peerless 830875 6.5" Nomex woofer.

Some of the design features:
.8 cu. ft. ported 2-way tuned to 47 Hz
24 db/oct 2500Hz crossover (18 db/oct electrical)
Braced ½” birch plywood cabinet with removable bottom
Quarter sawn cherry veneer
Watco Danish Oil finish (Natural)
My design goal was to find the best woofer I could afford coupled with a 24 db/oct crossover and still stay under the $225 budget. As many of you know I've built a number of speakers over the years with the Peerless HDS line and was actually hoping to try a different driver this time around. It just turned out I couldn't find something that modeled as well as the Peerless and stay in budget. Another goal was to build a light system and they came in at 17 lbs each. Total cost for drivers and crossover parts came in just under $215.
The boxes were made of 1/2 Baltic birch plywood with dado joints and slots cut to receive 1/4" stiffeners for cross bracing and battens to fasten the removable bottoms to.
Glue Up
Gluing in the battens. The short strips have the ends cut at a slight angle so they can be tipped into the slot in the box.
Gluing in the bracing
Gluing in the cross braces
Too be continued ...

Mine went in the morning and yours was in the afternoon, so it got hard to do direct comparisons. I'm really glad we got a chance to do the head-to-head.
