What happened ... please tell all
Yes, this is an older thread, but an interesting one.
Did many, or any, of these projects come to fruition?
I am guessing folks probably used ported cabinets with internal volumes between 130-145 liters and vent tuning between the mid-20s to the low-30's Hz. My guesses are driven by specs for the M2 cabinet and the S-4700 cabinet. I don't know of any other cabinets that use the original 2216-nd woofer.
Please share what you found or measured or photographed. I am quite interested since I recently received a pair of these woofers. They need a good home.
Thanks,
-Tom
