Square waves provide one of the best test signals for evaluating loudspeaker time domain performance, highlighting how effectively their system can recombine multiple sine wave components at the output with no phase distortion and flat amplitude levels.
While sine waves consist of just a single frequency component, square waves incorporate both their fundamental frequency as well as odd-numbered harmonics reaching into the radio-frequency (RF) range for added brightness to their signal.
Square waves can potentially be harmful to speakers due to their sudden and sharp transitions, which can create higher levels of distortion and heat in the speaker components. It is generally recommended to avoid sending square wave signals to speakers to prevent damage and ensure optimal performance.
They Can Distort Music
As frequency of a square wave increases, its sound becomes increasingly similar to that of a sine wave due to harmonics becoming inaudible at higher frequencies – an effect known as Gibbs phenomenon.
True square waves would switch instantly between high and low states without intermediate states; however, this is impossible in physical systems since this would require that diaphragm move infinitely fast at its edge and stop moving abruptly upon stopping its motion – hence square waves often exhibit ringing effects.
Square waves typically produce lower average power than sine waves; as such, playing them through speakers for extended periods may cause them to overheat and potentially damage. This is especially true of bass drivers; therefore it’s essential that speakers be selected based on the power handling capacity they can sustain without overheating.
They Can Damage Speakers
If your speakers are designed to handle maximum clean power (and are operating within their enclosure and crossover as intended) it should be rare that square waves cause them any harm. There may still be risks though such as over or under powering them, playing frequencies outside of their design range and improper care being given them.
As a waveform, square waves contain harmonics which extend all the way into radio frequency (RF), which are likely to damage speakers more than simply its base sine note. Triangle waves feature odd harmonics which taper off away from their root note and should therefore only cause harm if played loudly or for extended periods of time.
Square waves produce distortion at higher volumes that can result in clipped sounds, leading to faster heat build-up in speakers than standard or sine waves, potentially damaging them over time and potentially warping or melting the voice coil formers physically. This excessive heat could damage speakers over time as well.

Attracting sunshine and sand to your beach trip is everyone’s goal, but there are certain considerations you must keep in mind before diving in to the waters – particularly square waves – an amazing natural phenomenon that resembles chessboard patterns on the surface of the sea and can be observed from high points like lighthouses.
Square wave patterns may look beautiful from a distance, but they can be extremely dangerous when encountered on the water. Created when two different wave systems collide, these rip currents have caused numerous swimmers to drown as well as caused ship accidents or shipwrecks.
square waves differ from sine waves in that they produce harsher and brighter sound qualities due to having frequency components at whole odd-number multiples of their fundamental frequency.
They Can Damage Your Brain
When opposing waves collide in the ocean, they can sometimes form square waves – an unusual phenomena which produces an intricate chessboard pattern on its surface. Square waves are beautiful to observe and have become a tourist draw at certain spots like Ile de Re near La Rochelle in France – though these dangerous occurrences should be approached with caution at sea as they can cause significant rolling in vessels and boats, leading to serious incidents and possibly accidents.
Reason being, square waves have continuously shifting peaks and troughs compared to sine waves which remain at constant pressure levels. When changing its amplitude increases it takes longer for one cycle from peak to trough to complete and vice versa.
As your brain works harder to process the signal, this can result in eye jerks known as square-wave jerks (SWJ) that may be seen among individuals with Friedreich’s ataxia, for instance.
