And rest...........
Well a good evening to you all.
Dan, i think you need to completely re-evaluate your knowledge and abilities, as to be honest i can tell you, that you seem to know very little.
Yes you may "think" it will sound "w*nk" as you so eloquently put it, and maybe you know more than matt about car audio (although i doubt it) i am fairly certain you know a hell of a lot less than me. So i will be very interested to see your responses to my post.
Firstly, there is a DISTINCT difference between a SPL car and a Streetbass car. Laura, while "sort of" right i think misses the point - since there have been car stereos, there have been boomers. In fact 95% of the sales i make are to boomers of one level or another, be it one 12 in a box with 500w up it, or up to the Astro Van i built with 15000 w RMS on 9 * 15" subs.......
SQ in a car is pretty much dull to listen to, not enough bottom end and, well, its not that much fun.
SPL competitions evolved from "mine is louder than yours", and now a whole scene and industry has evolved from that with people pushing the boundaried in whole new ways.....there are people out there doing 160db off 1 x 10" subwoofer in a car. That is twice, then twice again what matts clio does. But it cannot play music.
HOWEVER, boomers came from people building ever larger car stereos, and then walls happened from that. If you are a basshead then a wall is the ultimate aim. Now Matts car is not a home hi-fi, but as he says is more a pa system on wheels, and what it does it does well.
Now i note you mention distortion on subwoofers. As the audio guru you are, would you like to tell me what causes distortion on a moving coil loudspeaker?

No? Ok - it is the movement of the coil out of the magnetic gap therefore lowering the BL (motor force) product of the woofer. At this point the motor is not able to control the movement of the cone accurately and a distortion of the output waveform occurs.
This is a fact of life on all woofers, Adires XBL2 tech, as well as JL's tech in the W7, and Orions use of a cloned XBL2 in the H2's removed this - however these can sound a bit flat, and also lack the midbass due to the inductance needed by the larger gap in the lower excursion part of the woofers throw, where midbass occurs.
Now in a large ported enclosure with a large, therefore effecient and controlling, port with a high BL woofer such as the DD99, distortion is effectively removed because of the reduced excursion compared to a sealed underdamped enclosure (yes, sealed boxed allow the sub to move more as they damp the woofer LESS) and are more accurate as long as GD is kept in check at the design stage (group delay)
But you knew that, right?
You also knew that you can buy large, several K amps that will not clip easily............therefore do not "distrort" as you put it?
I have done several walled cars, am building one at the moment, and i am confident it will be one of the cleanest, clearest bassers there is!
Anyway - i would like to know your inputs fella..................any questions?
