hardbass4u ... i want my bass to be infront la..
i just say that 5.25" very hard to play low frequency thus i will RISK that the bass will be heard coming from the back... which is not all of us want.
imho, the bigger the speaker, the easier for it to go for low frequency, but on the other side its hard to play the high frequencies to match the tweets (it can, but it will play in its cone-breakup zone which doesn't sound nice... to sensitive ears anyway)
a 3way system (not including sub) will be much harder to place n to tune compare to a 2 way to get the right staging n imaging, but to me, its the optimum way to go. also cost a lot of $$ T.T i wish i've a money tree at home
