As we know that to yield voice / good car audio it is of course we strive to be able to use all speaker type, Tweeter a.l yielding high frequency voice like percussion voice, fizz, without there is output voice bass.
Other Speaker is mid-range, yielding singer vowel voice following a little bass voice. Therefore both types of speaker the core important tweeter type, do not be needed by box / box which big so and can be put down wherever according to our will; desire direction, usually above facia or simply patch in door trim panel.
Last type is Sub-Woofer, we to study here, yielding low frequency only in the form of secretory bass voice. So that heard bass voice setle and is clear, better be made by special box. our Vehicle type, is Jeep type, MPV, salon sedan or Hatc-Back sedan and type / music stream which we take a fancy to ( jazz, rock, pop, classic, etc) it is of course follow to determine which better wear.
There is three speaker box form which one another have excess and insuffiency, y.i :
1. Box closed ( box sealed)
2. holey box ( box ported)
3. Aliance both ( Box Bandpass)
Box type closed.
Representing made easy and quickest/fastest box and also model / its for can be made is assorted. Big usually box / volume (in set of m3) have been determined and written by speaker each merk reference book. Its excess here, besides quickly and easy to making it, box this type of is not sensitive to made box volume inaccuracy. There is big difference of box 1 or 2 Cm, box sealed remain to still yield good voice. Its insuffiency is ability / its voice do not as hard as holey box (box ported) and still less at lowest frequency.
Holey box.
This type of given by ported / hole so that can be yield low frequency. long and Big of made ported influence yielded response frequency, thereby we earn to arrange its frequency response. If snugly making it, volume voice as small as, bass still heard by its excess oke. But that way there is its insuffiency that is this box very sensitive to mistake of measurement. A few volume difference by what instructed, its result very dissatisfactory. Once fail, unload box again. Besides weakness of this box to need compared to bigger place of box sealed. Don'T select/choose box this type of if spacious insufficient car room like Commercial type car / mpv.
Box Band-pass.
Box this type of aliance from both types of above. Usually one of the its side is endued with aklirik, as fashion, so that to be seen its it from outside. This type of likely there is box in box, given by ported / hole in one of the its side.
Its excess this type of can yield former compared to hardest bass voice both types of and its insuffiency is most difficult making it because its high.
Wrong once measure, bass voice can nope go out, but when snugly, best type box for the SPL OF. To a beginner which like jazz or classical, don't select/choose type box and time cleanseing many #
