I'm using it both as a subwoofer driver and as a top driver. 
 
This thing totally astonished me for the price, the sound reproduction of it is amazing, and you really can't complain about the build quality either. 
 
Performance as a subwoofer driver: 
 
I didn't expect such a clear and deep sound, especially since the manufacturer's specifications claim a response from 38Hz to 5kHz, but i can totally see where the "LF" part in the name is coming from, in the subwoofer enclosure i use it in it's playing loud and deep down to about 30Hz, which amazed me quite a bit. 
 
Performance as a Top/Fullrange cab mid driver: 
 
It's playing very clean and accurately (this will ofcourse depend on your enclosure) up to the claimed 5kHz 
It also sounds very lovely, every detail i wanted it to have, it actually does have. 
 
The only thing it's missing just a little bit is ruggedness/build quality, be sure to not screw it in too hard or you'll bend the mounting part of the basket. 
 
Otherwise, i do recommend this driver alot. 
 
Pro's: 
- Very clean and nicely sounding driver 
- Nice and clean bass/mids 
 
Cons: 
- Mounting place for the basket is kind-of bendable
