Ron just emailed me from ML; new panel is finally done. Due to Covid their having trouble getting the coating for the diaphragm. It took almost 7 months...good thing I am a very patient person. LolDon't let the price fool you, that is a decent woofer. Just keep the crossovers at 90Hz or above.
So basically for $740 you can totally refresh a Theater i (minus the tweeter, which should last a long time), which seems like a decent value relative to the cost of refreshing the larger units.
Congrats, and do the woofers at the same time, the cost is negligible.
