The VFL is built by SJA Industries and it is the same as an Atomic APX (or APXX) depending if it is the extreme or competition. Either way any VFL is U.S. made with better parts and can take a ton more abuse over the Chinese made HD or XFL. The HD and XFL are good subs BUT, they are built to have a good price over power handling and abuse. The VFL has a larger (better made) coil with much more motor force and much stiffer suspension. The XFL has a Chinese coil, a motor with less motor force and Chinese spiders that will not handle as much power.
wowo American bass has 2 vfl model subwoofers the V1 and V2. The V1 is rated at 750rms the V2 is ??????rms (aka the 818 motor). as for American bass line up of woofers it is as follows by rms SL,DX,XO,SQ,XD,TNT,VFLV1,XFL,HD,VFLV2,Full Custom!
To the OP, If its the VFL comp with the 818 motor it will smoke the XFL, The 818 motor is worth almost as much as the whole xfl! If its the V1 vfl then it would be alittle upgrade to go with the XFL. Do not get me wrong the XFL subs are a under rated beast but not in comparison to the true VFL!
