The liner excersion of these subs is excellent. You put them in your car and they dont sound very loud, because they are practicly distortionless. but when you get out of your car and notice your windsheild loose..you'll know
Image Dynamics "MAX 12" will play just as good as the W7(the max 12 has a frequency response of 8hz to 120hz+/-2.3db and 23mm of one way Xmax) And the max 12 retails for 449$ US dollars, alot less money for the same performance.
Check the febuary/march issue of car stereo reveiw's MOBILE ENTERTAINMENT for a complete reveiw of the sub.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
