Well you really can't. Lets face it to be a db dragger you have to have some serious dedication, time and money. testing, building and tuning almost every spare time you got just to gain 1/10 of db. but its a challenge and you got to be up to it. There is no practicality in it, like there is no practicality in playing your system for 30 seconds straight to control it to hit that perfect 9.9. BUT ITS FUN!!!!!
Drag or Race your a db dragger. Bass Race has seriously saved this sport but, without the manufactures this sport wouldn't exist. In order for us to develope back to the level Db Drag was when it first started it has to evolve. I'm not sure though if the approach is being done correctly.
