sikk nation, when you say "motor" you mean the magnet in the voice coil right? (sorry...newb here lol) So basically the stronger or better quality the magnet the faster the sub will respond regardless of the cone size?:dunno:

not always.. there's so many factors involved.. but in general terms, the bgger the cone.. the bigger the motor (magnetic force)

I think I'm starting to get it now. Thanks guys :smilie_da

Usuaully you only get proportionallly sized motors for higher end equipment though.

what brand names would you consider "high end" (list all of them that you know of, I want to try to learn as much about this topic as i can because it has been buggin me for quite some time now. Especially when you hear a different story from each place)

each place/person has different experience levels.. Futureshop sales staff for the clear majority are not real car audio guys. Just salesman that still believe that wattage is the only thing that determiens performance. for high end brans in terms of SQ

Morel,
Focal,
Hertz,
Dynaudio,
Rainbow,
Hybrid Audio,
CDT,
Diamond Audio
to name a few.

One of my cars currently has Focal 40KX (16" Polykevlar subwoofer) in it and everyone seems to to think I'm running alot of 8's because of the output and tightness of the bass. Mind you it's a $1600 sub, but it does go back to "You get what you pay for"

Focal subs are by far one of the best of the best in terms of SQ. I love Focal subs and I'm running 33v2 in a sealed box. I believe the KX and Utopias are designed for ported box.

or you can put a bigger motor in a smaller sub + lots of power and get osmething gnar :)

Also yah, Wanted to say that Ive noticed most\lots of 18's have dual or even quad 4" voice coils which is double the size of more dual voice coil 12's (2" VC) more magnet coverage meaning more energy transfered to the cone =D and I dunno if im right on this one, maybe sikk knows. But usually more voicecoils or wtvr, means more Xmax or excursion??? Only sometimes?? They could have a single VC with same Xmax as A DVC but just make make each voice coil half the size so theres more control.. Or do I have this whole voice coil thing wrong ahaha

VC configuration for SQ terms has more to do with inductance than anything else. For SPL monster subs it means shorter individual runs of wire around the former so the wire making up the coil itelf can handle more currect before adding heat to the equation. As for XMAX or SPl.. VC configuration is primarily for wiring options.

Also the V1'a and Utopia subs are mean for ported, the V2's and KX's (with the exception of 46KX are designed for smaller sealed applications)
