How do you test the bass from the speakers with your phone?

Everyone knows that not all speakers are the same. Some are cheaper, some more expensive, some better, some worse.

A good speaker must have a response frequency from 20 Hz to 20.000 HZ, all at a uniform sound pressure across the beach around the 90 db SPL (sound pressure level).
See the image below:

For bass we need a big, heavy and expensive speaker. we also need a large enough sounding board and some filters for a sound as accurate as possible. All this costs, and the speakers are cheap, that's why they are cheap, because they are cheap… .uuuu, how deep I was!

Big names have high prices, but quality is not always pricey. Buy speakers for you, for your ear, not to praise your friends with the brand.

I have a Microlab sound system, like that, which sounds extremely good and does not cost a fortune. For a whole lot of years I used these speakers with pleasure and I did not feel any need for more seconds.

First we have to connect to them, either by cable or by Bluetooth. Here again refer to active speakers that have their own amplifier, and which can amplify the signal from the phone.

Passive speakers need an amplification station.
