Pros: Great performance, good sensitivity
Cons: None

This was the subwoofer I selected after trying the Rainbow Profi 12 and Vanadium 12, Image Dynamics IDmax, Orion H2, and RLP 12. I use 2 w12gti mkII subwoofers in an infinite baffle setup. They are able to play tremendously low and flat while never sounding sloppy. I have my two subs wired in a series/parallel configuration to produce a final impedance of 6 ohms (1.5 ohms is also possible).

DIYMA has a relatively thorough review of the JBL Gti series subwoofers.
