About have my third box finished. Making a 5.25 CF box, built to match with my two SI boxes under my screen. SI boxes are 40" x 23" x 12". The third one is 48" x 23" x 12". The third box is the new home for my Maelstrom-X 18". I have not handled this driver in a few years. The Mal-X (55lbs) sure makes the SI feel like a lightweight.
Output wise they match up pretty good. Should have these done by Friday or Saturday, then I can start calibrating the sub system again.
Glad these SI's came along, since they match up decent with the Mal-X and are available at a good price.
