Here's some porn from me.
Just got the new tops for my subs. Each has a FaitalPro HF1440 + 18sound XR1464C horn and four ScanSpeak 15WU midwoofers. Amplification and filtering done by a Hypex FA253 plate amp. Sounds absolutely killer. Sadly, the amp for the big subs seems to be dying, so I'm listening to the tops only. Luckily, they go down to lower thirties. The resulting area of the four midwoofers exceeds a single 10" woofer, so it can go pretty loud as well with that +/-9mm Xlin.
Here's a better look of the thing.
