In these cases, the normal tone controls don't work so well as the bass adjustment can be too 'boomy' as it's lifting too much above 100Hz.īigger speakers are fine, and my main system running floor stander speakers does not have a bass boost. To 70Hz only and I still prefer a lift of bass below 100Hz, especially when I'm listening at low volumes such as when I'm working and listening to the radio. Otherwise, at their size, they'd overheat with big amplifiers.įor small 'hi-fi' speakers, i.e., bookshelf ported or non-ported speakers with 4 to 5 inch drivers, these can do quite well, but response is often quoted down Remembering that small, portable, speakers need to have someĮfficiency so they can respond with low, battery powered amplifiers. Struggle reproducing frequencies efficiently below 200Hz and drop quite rapidly after 100Hz. The speakers in a small box/cabinet with a small baffle are going to Speakers are constrained by Hofmann's Iron Law - Small cabinet, High efficiency, Bass response - pick any two!įor small/miniature speakers, especially portable ones, physics plays a restriction. Which have reasonable sized bookshelf speakers, but response below 100Hz still needs a little help, especially when listening at low volumes. I've now setup and used a number of bass boost circuits, and they can lift the low-end for systems which use small speakers (i.e., portable), or systems This article is dedicated to methods of boosting bass for systems where it's desired by adding circuits before the amplifier.īass is a troublesome frequency, but we feel dissatisfied when listening to a setup that just doesn't have enough bass.

What is bass boost
