I put these refurbed 416s into an 11 cu/ft cabinet (before bracing and driver) with a Great Heil on top. The 416 is crossed at 850Hz 1st order, the Heil comes in at 1,000Hz 3rd order. Two 4” ports on the front, cabinets set on 4” feet. The cabinets are 40” wide x 30” high (before feet, after feet the top of the cabinets are at ear level) x 20” deep. I used Obligato Oil caps and 14 gauge coils for the crossover, Cat 5e Plenum for speaker cables.
I drive these with a 2A3 SET amp that I built a few years ago, probably puts out 3 watts or so.
I’m sure I can get more out of them, and I will in time. But even as they are they sound pretty darn good, and I have been enjoying them a lot over the past few months. I finished these just January 2013, or I should say I started listening to them then. Not finished yet, probably won’t be truly “finished” for years. I have a friend who I bought the 416s from who has been very helpful so far, and I expect will continue to help me.
Thanks for looking.
