Speakers are the most important part of any Home Theater system. If you don’t buy good quality speakers then you will hardly enjoy any movies in the Home theater. While buying a speaker you go on Google and look out for those particular brands and you don't know that how can you understand the comparison between two speakers.

There's a disclaimer before we get into the blog these 5 things are something based upon other factors as well. but apart from that in terms of specs, these are the 5 specs.


The importance is calculated in ohms(Ω). it's like the resistance. for me is like a speed breaker. Imagine you driving your car and you are at a good speed of hundred kilometers per hour and you come across a speed breaker what would you do? you will reduce the speed right now the speed is reduced based upon the height of the speed breaker.

The speed breaker is nothing but resistance and impedance. in this industry now ideal impedance at you come across in most of the home theatre speakers is an8Ω, 6Ω, 4Ω.

Sensitivity –

Sensitivity is measured in dB (Decibel) The higher the sensitivity rating, the louder will be the sound from your speaker.

Speaker sensitivity refers to a speaker's ability to convert power into actual sound — that is, how much power you need to make your speaker function properly.

speaker sensitivity is measured by placing a microphone one meter in front of the speaker and running a single watt of power from the amp to the speaker. Whenever you buying a speaker you have to check what sort of sensitivity does a speaker carries and can you have to go for a better sensitivity speaker.

Frequency Response -

The third parameter that you should consider before buying a speaker is the frequency response.A speaker's frequency response range is a measurement of how wide a selection of sounds it can reproduce. The human ear is capable of hearing sounds from 20 - 20,000 Hz. The lower the number the lower the tone and vice versa.

Most speakers are capable of responding from around 45 - 20,000 Hz.Better the frequency response better would be the output from the speaker. low frequencies satellite start from 100hz your bookshelf, in-wall, on-wall speakers would start from around 60hzand your floor standing would start from 40hz these are the frequency range.

Power -

Now there are two types of power when we compare the systems. Usually branded Systems Based on PMPO (Peak music power output) but what we said when we talk about the hundred-watt speaker that 100watt is nothing but an RMS value which means root mean square value and its way lower than PMPO output. but yet the sound output that the speakers will deliver will be much better than a PMPO speaker.

what you need to check also is the wattage of the speaker. it can drive the speaker so what matters is higher the power higher would be output from the speakers.

dimension -

The dimension of speakers is important when it comes to blending the speakers in your room design. It is important to understand them before making a decision.

In today's environment, we are all particular about the size of the speaker and how it will look when we putit on the wall. I am going to lose my floor space if yes then how much? all these things do matter.

When you are looking to design a good cinema room and you want to install the speakers matching with your aesthetics, it is very very important that you look out for your dimension of the speaker, depth, height, and width of the speaker.
