One of the reason i went with the w7 is JL name and rep for making a great sounding sub. I just dont want a sub to be lound and shake my car,(Any sub with enought wats can do that) but reproduce the note out of the music. I dont know if they do test for this but like a drum beat or a base gitaur and a base violine I just wounder wich sub would be the best at reproducing the excat note. i would bet JL but could be wrong i am no teck just some one that likes sound.
ps:sorry for the bad spelling i need spell check
