raytard Posted March 31, 2009 Report Share Posted March 31, 2009 xmax theoretically increases the air moved, and assuming the same size cone (bot 15's for arguments sake), the one moving farther is theoretically louder, and more xmax gives the ability to play lower linearly at louder volumes. for spl though, in most cases sensitivity and box design will help you out more than xmax not saying xxx's will be quiet, but its not the end all be all of spl the 4 dc's will have far more cone area than the xxx's, and i think the sensitivity is higher too, idr offhand which would proobably mean a higher spl potential Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...
Guest Posted March 31, 2009 Report Share Posted March 31, 2009 for spl though, in most cases sensitivity and box design will help you out more than xmax not saying xxx's will be quiet, but its not the end all be all of spl x2, thats why the BTL's sensitivity is so high. so it can get extremely loud and about the xxx thing, they have a high xmax probably because they are a SQ woofer and it needs to drop low (my guess) Link to comment Share on other sites More sharing options...
Neel Posted March 31, 2009 Report Share Posted March 31, 2009 i dont think so. its not how far out you can punch , its how hard you can punch is the analogy i have always gone by. Too Much Stuff to list . Link to comment Share on other sites More sharing options...
Boon Posted March 31, 2009 Report Share Posted March 31, 2009 i dont think so. its not how far out you can punch , its how hard you can punch is the analogy i have always gone by. That's pretty much it. It's not just about how much air you can move, it's about how much energy you can transfer to that air. 10.x volts fo' life!

I would go with four 18s purely for the cone area, although the XXX has the Xmax the IAs or DC 18s will be louder and sound better IMO -Drew I am a United States Military Arts and Crafts Professional.

loganberry Posted March 31, 2009 Report Share Posted March 31, 2009 stephen posted up something a whileback about xmax having no relativity to spl, ill try and keep an eye out for it, it was very interesting, xmax does have a good bit to do with hair tricks tho My F-150 Build GET ON THE BANDWAGON what if they tried messing with the amps when the subs werent louder hahah jk Link to comment Share on other sites More sharing options...
