hindi naman po mahirap baklasin anf sub-woofer. naka-screw lang naman ito sa ikalawang wall sa loob. at ang unang wall (outer) sa harap nito ay naka-screw din. hassle free.
 
sir pwede patingin nung back part nung box para magaya ko yung line out! salamat
 
boss bassbooster thanks sa pag-invite anyway my lay-out kaba boss ng subzero? 2 sub kasi gagawin ko nabigay muna kasi sa akin yung EL-36...
 
Hay wala talaga ako masabi sayo boss bassbosster maraming-marami salamat po.....:thumbsup:
 
eto sample guide para may reference ka., pero try to compute pa din., yung speaker parameter na gagamitin in cu.ft para konti lang ang % error at para din malaman natin kung ilang ang require na internal volume, yung mismong pinaka box ng woofer sa internal ng subzero.,

anong model ng x12 yan.. nag search ako ng x12 amplifiers copy-cut lang pala ng x12 ang V12 amplifiers, daming lumabas halos kamuka lang ng v12 amp ang x12 amps

kung baga sa v12 amp yan ba yung V12 805.. may built in crossover naman po ata yan., nakalagay naman bridgeable.. i set mo yung isang ch sa Low o LPF low pass filter, then i set mo sa 40hz or 60hz dipende sa gusto mong tunog ng bass kung malambot o matigas para low frequency tapos kung may Db gain i set mo sa 3 or 6 Db para lumakas ang bayo sa low frequency,.tapos dun mo ikabit yung woofer mo sa channel na isinet mo na LPF..
