Thanks master Nelson... kakareview ko lang din ng EQ sa youtube it can remove unnecessary noise pala so I think i need this stuff...
Last question master nelson if I change my subwoofer to a single 18 inches subwoofer with the same enclosure of marco rather than purchasing another 12 inch sub can i still get the same gapang effect...
I want to save room space kasi sana pag 2 pcs kasi masyado na malaki...hehe
Normally, wala dapat noise ang system mo. Kung may hiss or loud hum (excluding tube system), may problem ang system mo. you need to fix your system, not EQ it. By EQing the hiss (not recorded) of your system, you also sacrifice the details in the recording that the recording company wants you to hear. Example, may hiss sa 10khz due to faulty amp, by lowering the 10khz freq, yun mga decay/extension ng voice, cymbals, ma-le-lessen
Though there are unnecessary noises din na kasama sa recording, why would you want that removed? Masarap madinig yun ubo ng mga musicians from the back etc.
Ano yun unnecessary noise na sinasabi mo?
Normally, bigger drivers would require bigger enclosures to maximize it's output and tuning. My 15" sub has more than 8 cubic feet of area. Pwede siguro, i seal mo na lang. But make sure na kaya ng pilyo amp mo ang 18" sealed. And prior to replacing it, kakasya pa ba yun 18" subwoofer (width and/or depth) sa enclosure? Baka naman pwede na ang 15" sa iyo. or add passive radiator sa 15" or 18" sub enclosure. pero, ang alam ko, kasing price na ng sub ang mga passive radiators.
