ive heard plenty of them, they just arent nice enough sounding for me,
After hearing RE, DD, Treo, TC Sounds, Adire, higher end stuff theres no way i'll go back to a kicker.
Its just personal preference i guess but theres nothing a L7 can do that i cant get better sound out of. Money doesnt really matter to me when shopping for my sub/sub amp, so the cheapness of a L7 is out the window as an excuse.
If dude wants to throw a 3k amp at some L7's all day thats on him but i was asked my opinion and i feel 3kwatts is better used on somethign besides L7s
