as usual, kailangan malaman muna ang sukat (length, width, height) at korte sa loob ng simbahan, pati na rin ang seating capacity. kung may live band kayo, malabo gamitin ang ceiling speakers. mas okey kung makakapunta ka sa audiophile para ma design namin mabuti ang sound system ninyo according to your budget at marami pang high quality audio equipment na pwedeng pagpilian doon.

sir,
hindi po xa ceiling speaker,
kya ko lang po sinabi na low ceiling speaker kc maliit,
kaya tamang tama lang po samin,
hindi makakasagabal sa vision ng mga tao,
pero may box parin po siya,
un nga lang maliit

ang seating capacity po ay nasa 150-200,
hindi po ba advisable ang maliliit na speaker pang live band kahit madami?
thanks po sir

okey ay ang distributed sound system (madami, maliit na speaker) para sa speech applications lang pero kailangan mo pa rin ng hiwalay na sound reinforcement system para sa live band. daan ka sa audiophile para maayos ang sound system design...

I think you know much better kung anong size ng speaker para sa house of worship nyo. Actually pwede parin yan, but don't expect to much loudness or else distortion will occur and worse to happen, masunugan ka ng speaker driver(if overdriven). Me drawback sa ganitong size ng driver(6"), so try to exercise restraint pagdating sa volume. If you really like the said speaker, for size reason alone, based on the spec., yung lowest frequency nya eh nasa 80Hz, your safe to use if for vocals only up to high (mid to high frequency). Now, if your using a mixer, try to cut-off the signal going to this speaker from around 180Hz to 240Hz (to reduce thump, boom or unwanted rumble generated by this low freq).  Reason is, ayaw nating sumama yung  bass at drums signals. This two instruments ang nagpapahirap sa speaker due to over-excursion movement ng cone, if not properly cut-off from the signal, affecting yung vocal range ng loudspeaker. Now, since you have the subwoofer, from mixer, dun mo ipasok yung signal na galing  sa bass guitar plus galing sa drums. At this point, try to adjust yung upper cut-off frequency setting ng subwoofer mo (around 240Hz or higher )kung meron syang facility to adjust it, para mag-match or maging seemless yung integration ng  tunog ng dalawa ( vocal speaker + subwoofer ).

Since you want distributed dispersion of sound, If you notice sa spec: Dispersion(HxV) 90°×60°; H stand for Horizontal dispersion. Eto yung designed sound coverage ng speaker which is 90degrees (45degrees side to side starting from center of cone of the mid-bass driver). It means any audience seated or located within 90degrees horizontally will be covered. This figure will help you also para malaman mo kung saan mo dapat ilagay yung susunod na speaker mo after selecting yung location ng 1st speaker. So the next location for 2nd speaker, is before mawala yung 90degrees na coverage sa audience nung 1st speaker. Then, ganun din sa 3rd speaker and so on. We want equal audience sound distribution here. Next, V stand for Vertical dispersion ng signal which is 60degrees (30/30degrees vertically from center of the cone ng mid/bass driver). As you said, low ceiling sya, kaya try to angled down or nakayuko yung speaker facing sa audience para less yung dispersion ng signal na tatama sa ceiling. Gusto nating ma-minimize dito yung bounce reflections from ceiling na magpapagulo sa vocal clarity na iproproduce ng loudspeaker. I hope this helps.
