how do you know they " no way" sound good? the reason alot of spl woofer dont sound well it what was exlained before the strong motor and stiff suspension, give it a "high tuned" sound imo. but thats kinda like how al lthe real sq car i have heard sound..kinda like an 18 in .5 cu ft....to a point most every woofer will play music well enough, and most people are a looking for bass for crusing around and dropping lows will be happy with them , now these guys who claim to be able ot hear the differance from a 6.5 being 1inch form perfect alignment and listen to classical or whatever just to hear the mids crispness..they will disagree...but i can say from experiance..a street cruiser who likes to bump around ..wouldnt like the sound of a real sq car....
