PA System and Speaker Inquiry

[golts_vex13]

Good day mga ka-PM! Tamad lang siguro ako maghanap ng topic neto pero magtanong na lang din ako. TIA! 
I want to inquire if ano ba ang compatible speakers para sa isang PA system.
Let's say ang output power ng PA system eh 4ohms: 200 watts RMS, ano po ang compatible speaker sa kanya? Pasok ba ang 6ohms 180watts speaker sa kanya?

Eto ung specs ng balak kong bilhin na 2nd hand na PA which is Carvin PA620:
Frequency Response: 20Hz-20KHz ±1dB
Total Harmonic Distortion: Less than 1%
Equivalent Input Noise: 150 ohm source: -110dBu
Output Noise: -90dBu Master Line Out
(all levels minimum)
Output Power: PA410 4½: 100 watts RMS
PA620 4½: 200 watts RMS
Output Headroom: +20dB 1/4” unbalanced
Maximum Gain: Mic in to Master Line Out: 65dB
Crosstalk: Adjacent ch’s: -60db at 1KHz
Common Mode Rejection: -75db at 1KHz
Phantom Power: All XLR Mic in channels
Channel EQ.: HI: 12KHz ±15dB
LOW: 85Hz ±15dB
Graphic EQ.: 7 Band Oct. Intervals ±12dB
100, 250, 1k, 2.5k, 5k, 10k
Mic Input: Balanced XLR input
Line Input: Unbalanced 1/4” Phone Jack
Power Requirements: PA410 120 or 240 VAC - 110VA
PA620 120 or 240 VAC - 220VA
Size: 16”W x8”D x 8.25”H
Weight: PA410: 15lbs., PA620: 18lbs
Options: FS22 Footswitch, CV620 cover

Maraming salamat po sa inyo! Mabuhay po kayo!

importanteng magkamatch ang resistance (ohms) ng speaker at amp dahil pag hindi, may isa jang masisira.

How about this one Sir Ralph?



Anu ba ang posibleng maging problem in the long run? Thanks!

Palaisipan lagi ang pag matching ng speakers sa mga amplifiers.  Kaya mas ok na mag "active/powered" speakers ngayon. Built-in na yun amp, limiter, crossover, equalizer at matched na yun mga speakers. Higit sa lahat, affordable na yun mga new models ngayon at high output na din. Just my 2 cents
