Highs so crisp, clear and most importantly loud.
This is for people that can't hear over the bass and speaker can't hack it. Screw the "cheap1" tweeters one off these and your straight.
Ima lil crazy and have two 4" and two 2" roadthunders and am not disappointed.
Like I said these are LOUD like a concert in the car and have ringing ears when you shut it off.
Being right in front of the screaming tweeters feels like a slap to the face! Buy 'em while they got em.
Ps. these last a long time just don't run them with out the bass blockers or you'll pop the voice coil (15$) but lasted a week of abuse only popped on max volume. And a lil acetone to rub the red paint and it'll show the nice metal finish.

Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

I put these in my Z3 (that I was giving to my daughter).
Right behind the seats so the back of the seat was at best two inches from the speaker.
But they look REAL cool shining out from the back wall.
Ran 150w RMS through them and I telling you these babies make the high-hat sing when cruising down the road with the top down.
Sound a bit tinny when pumping lower juice through them but the deadening of the seat back worked that out.
Great horn for the price - make note they are 8-ohm...
Knocked them down slightly for sucking up so much juice.
Update - after nearly three years I rode in the car with my daughter today and they are still cranking crystal clear making the top down cruise so much more enjoyable.
