I have heard about these speakers many times on the forum. They seems to have gotten great reviews. I wanted to know if the builder had choosen to share his design with others DIYers. Is there designs written up anywhere for these? If not that's no problem I understand it's totally up to the builder whether or not he wants to share his design.

The basics of box and XO are here:

Also, search for the Iowa midrange results thread. That thread contains a bit of info.
This is a MLTL box. It has 7oz of polyfil evenly distributed within the top 1/2 of the space, including directly behind the drivers.
Crossover is external - using Speakon connectors. This is to allow unobstructed airflow. The port is 2" X 4", mounted 4" from the bottom on the front - but could be back. It only passes information at the resonance frequency.
Mid and Tweeter are offset from center 1/2 inch. The drivers are mounted as closely together as possible.
Hope this helps, and if you build them, you will enjoy them. The keep surprising me with the nice mix of smoothness and detail.
Proper credit must go to Paul K. for the MLTL alignment, Bob Cordell for the conceptual inspiration, and Mike Rispoli for hours of help tweaking the voicing. I work in a no measurements zone.Last edited by maynardg; 12-07-2008, 12:14 AM.
