RMS: The higher the RMS, the louder the sound. So more RMS is needed if multiple people need to be heard. So, it is better to consider the size of the room and decide how much rms will be good for you.
Frequency Response: This is referred to as Hertz. A human can hear from 20 Hz to 20 kHz so it is better to choose the frequency closest to it. However, there is no set frequency for buying speakers.
Impedance: Impedance is measured in ohms. Most speakers have a 4-ohms impedance, which is sufficient for home audio. However, make sure that all the speakers you choose have the same ohms.
Sensitivity: The higher the sensitivity the better as it will take less power to produce high quality sound. Sensitivity is measured in decibels. The sensitivity range is 88 decibels to 100 decibels.
Number of Speakers: Determine how many speakers you need because the price will depend on that. If you want to cover a large area, multiple speakers will work best. Single or double speakers will run for personal use. Speakers in Bangladesh market are usually sold as single or double speakers and 2:1, 3:1, 4:1, 5:1, 7:1 etc. which means 1 subwoofer is included with the mentioned number of speakers.
Connectivity: Most speakers have a wired connection, but some speakers support Bluetooth connectivity to the audio system. So check before you buy.
