ang galing ng explanation mo tungkol dyan sa competition. salamat. pero ang miata maliit ang cabin space nya, compara sa excursion kaya madali icompress ang hangin. yan ang labanan sa SPL kaya ideal dyan ang maliit na hatchback type na cotse. nakuha ko na explanation mo pero medyo nag cacontradition ka ng conte .. sa sagot mo kay glennster, parang nagulat ka na may nag sabi na iba ang excursion speed ng different size sub. pero ngayon bumawi ka at sabi mo "kung nahuhuli man yun 8 sa 12 of the same sub baka the sub was not meant to play fast, meaning its not as precise or the motor construction was made for a different application." so kung bumili ako ng brand x sub na "not meant to play fast" eh di iba ang excursion speed ng different size subs ng brand x? sa tingin ko iiba parin ang speed eh. also, nag comparison test kapala ng 10inch and 12 inch solobric. ok yan ah paano yan? same car, same amp, same enclosure type same lahat?? tapos na conclude mo na iba ang excursion speed ng 10inch at 12inch. tapos nag comparison ka rin ng 10inch at 12inch W7? wow. ano yan? same car, same amp, same enclosure blah blah blah? gets mo ba? wag kang mainis at ganyan ang impression ng tao sa pag salita mo. ngayon paano yan? so umamin ka na iba ren pala ang excursion speed ng iba ibang sub size noh? eh di, tama pala si glennster! kasi parang kinocontra mo eh. peace tayo sister este brother katuwahan lang.
