Well I believe the latest specs I posted above are pretty accurate due to a comparison to a 416-8c I have tested and the specs almost match published specs.

I'm disappointed with the high FS especially one measuring 40hz. That could still work fine if I decided to use it with subwoofers below 50hz or so but I originally had my heart set on MLTL cabinets. However I'm unsure if the QTS of .5 on one woofer isn't to far off for MLTL design too. Seems better suited to sealed or aperiodic loading.

I don't regret having the four woofers reconed because as mentioned the cones all had blemishes and such due to age. I wanted them to look new which they do now.

I'm not in any hurry to complete this design as this is suppose to be a retirement project for me. My plan was to collect everything needed but actually do the build around spring of next year when I retire and have extra free time on my hands. (still a year away)

Hence I'm just going to think on this design a lot between now and then. Another problem I'd mentioned in my MLTL thread is I'm not sure where the put the horns because of the cabinets needing to be so tall in order to use two 416's per channel.

Lots to plan and think about. Thanks to everyone who has replied to all of my threads here. I've learned a lot already and appreciate everyone's suggestions / ideas!
