"Thank you to the three of you. I have so many sleepless nights already regarding this sound setup that I am planning to do. One more question is this. The bass that I wanted it to produce is loud but yet soft and has a lot of quality in it. Can I accomplish this using this drivers and amps. If I make it passive will it sound better? thanks for the help guys."

Sir sa sub you need to remember the bigger the cone area the more air it moves.. ( tika muna paki ikot po sa baso Pajerokid naghihintay si Gonzo..hehehe:juice

if want it loud like what I said earlier get the 10" kung seald lang talaga ang option.. dahil kung ang 8" ang ilagay mo sa seald baka konti lang deperensya or kasing lakas or baka maging midbass ang tunog nyan..coz if want soft but loud it is not the driver its the way you tune your enclosure.. a friend of mine single 8" DD sub in 1.75 cub/ft tuned to 32hz(ported)..sounds really amazing and clean dahil na sa proper enclosure and design.. ( saan na po yong baso..hehehe)..

and with the subs theres no need to use any passive x-over dahil kung mono-block amp ang bibilhin mo design na yan pang sub..at may mga amp na may LPF feature din kahit hindi mono-block.. again sir kung gusto mo soft and loud hindi ang driver ang maydahilan kung di ang properly design enclosure and tuning.. kung ako ang tatanongin sa gusto mo.. ma achieve yan sa 8" at sa amp mo but in a ported enclosure tuned to 32 or 33hz dependi sa TS parameters ng sub mo..

just made this recently ito ussually ang laman ng tuned enclosure pinakita ko lang para may idea ka slot design ito at may round port din na design..
( dahil ang tagal ng baso kasi...hehehe) this enclosure was tune to 33hz..yong sinabi mo na soft and loud makukuha nito na tuning.. Good luck sir! (Heeck! where's da road?..hehehhe..):juice:
