The Titan was a something I wanted to do a long time ago when the Maximus thread was started to see what people might want in a 3-way. Long story short, that thread went a bit over the top and gave us the Maximus-18, which later got dual woofers and called the 1899....Bwaslo did the crossover work for that crazy idea.
And of course the Maximus-12 that Jeff Bagby helped with.
Tux had just finished up the 1299 and a flat pack ended up being a bit too big for shipping, which pretty much meant a bigger 1599 couldn't have a flat pack either. So I started thinking of a dual 15" 3-way beast using the horns that sit above a more flat pack friendly cabinet. But the enclosure size still ended up too big with dual woofers and it also got pretty tall.
Then after hearing a single 12" Magnum woofer Eminence made for us, I realized we could probably get some incredible output with the right 15" woofer. I talked with MTG90 and he modeled/tested a few 15's that were okay, but we wanted something crazier. Last year Eminence offered to make a 15" version of the Magnum-12 with the santoprene surround, but the sensitivity wasn't going to be as high as we wanted. So it ended up using a pro audio surround that allowed for a high X-max but also kept the sensitivity high enough. After some testing......yeh, it's a powerful beast.....and the project began.
I believe this 15" can move twice as much air as most pro audio woofers.
Feast your eyes on a video that MTG90 took:
