I'd take a zed made lanzar over a Kenwood. Depends on the build house. Don't discount tc300 either.

What impressed me was a sub setup that hit 130's w/1watt Don't always need power to reach your output goals. But remember, the "sound" of your sub is determined by your mid as well as tweeter depending on the drum note. Majority of the bass fundamentals start with a sub while transients complete the sound at higher frequencies. Ever sit in a vehicle specific for SPL and it's so loud you can't "hear" the sub? The mids aren't able to match the output of the sub(s).
