I've heard amazing things about the tweeters and other drivers!
It will be a ways down the road.
At the time, I payed 1850 for my m80 v3 with die cast baskets and dual inputs...and it's hard to justify double that for updated drivers and an extra woofer in the m100
But I suffer from upgraditis....so it'll probably happen one way or another lol
I'm an axiom customer for life. They've been amazing to me thus far and their products are incredible
