Matching amplifier and speakers

[kthangam]

Dear HifiVision team,

I got a small old amplifier and the detail below:

Spacetech K18 Mic Mix Amplifier
CSA file # LL99583
120 V
60Hz
20 Watts
2 mics
input (black and white)
output ( black and white)
2 speakers outlet

My question is:

Which type of speakers are Ok for this unit to use for karaoke singing?
Room size 60'x30' and the audience will be 30 people.

ur room size is too big for the amp and the speaker u are gonna buy for this AMP. IMO u need to buy AMP and Speaker both for this room.

What is ur budget ?i dont think I amp ur having dont suffice u, cos ur room is huge and hope ur room looks like small auditorium;-)

Thank yo for the comments,

If I will use this amp for room size 25'X15' then what are the speakers OK?

 

[abhi_jollyguy]

U need minimum 200W RMS per channel speaker to fill ur room with the sound and to drive this much watt RMS speaker u definitely need to buy AMP, coz ur present AMP is not sufficient to drive his much wattage speaker to fill ur room with sound.

what's ur budget and u need stereo setup or 5 channel setup?

I found two used speakers - good condition.
Dynamic Audio Pro poly series 1901:

Maximum Watts 120
Minimum power handling Watts 5
Frequency response 43 Hz - 25Khz
Efficiency 98 dB per Watt
Variable leval control
Normal impedance 8 ohms

As my small amp has 20 Watts power, can I use these speakers without cousing any problem to my amp or speakers?

Also, it has facility to adjust -2dB/ +2dB/ Normal/ High range
Please help me to understand how to use this facility too.

Thanks.

As I have already said tht u need to buy New AMP to drive ur speaker which can fill ur room with sound and atleast 150W - 200W RMS Speakers u need.
