In school, I made a speaker out of wood and made the sound bounce off the inner walls strengthening the sound, but its’ sound quality and loudness compared to its size, vs real ones is major. What exactly is going on inside the speaker?
Additionally, how is bass empowered?
(sorry if this is really obvious, I just don’t understand haha)
In: Technology
The three main variables are
* The driver
* The enclosure
* Electrical EQ
I don’t know the various parameters of the speaker. There’s an overall parameter of “at what frequency does the efficiency of the speaker start dropping off”
This would typically be stated as the frequency (in Hz) at which the sound is 3dB less than nominal.
The enclosure can be tuned to increase the level of some frequencies at the expense of reducing efficiency at others.
This can be used to allow the speaker to produce louder or lower bass.
A simple tuning is porting the box so that some of the pressure from the rear of the driver is allowed to be redirected to the exterior of the box.
EQ can be used to increase the level of some frequencies at the expense of using more power from the amplifier and to put the driver under more strain.
One way to make a speaker appear to be bassier than it really is would be to design it to make some bass frequencies louder than they should be. This “hypes up” the sound at the expense of accuracy.
There’s also a type of processing that distorts the bass so that our brain thinks that a lower note than is present is being played. Eg hardware that does processing Similar to [Waves MaxxBass](https://www.waves.com/plugins/maxxbass)
