Loud Speaker?
ChrisGreece52:
Hello i got 2 8 watt 14 ohm 2" speakers and i am wondering if i can increase the max volume (like overcklocking the speaker) with any kind of way ....
This may sound crazy but it may be possible i think.
Also could i use both speakers as one (by connecting them in parallel or in series ?)
c4757p:
Increase the voltage they are driven with, obviously. Just like overclocking a CPU, you risk damaging them by running them above rated power.
As for series/parallel - have you ever wondered why an orchestra isn't dozens of times louder than a trumpet, or why it has so many damn violins? Sound volume adds logarithmically.
Psi:
If you put the two 14ohm speakers in parallel you lower the total resistance to 7ohms.
The amplifier will then put more power into the speaker for the same position on the volume knob.
But be aware that you're pushing the amplifier harder in order to get more volume out of it.
Depending on the specs of the amplifier you could damage it with low ohm speaker loads.
In reality i doubt you'd damage it with 7 ohms since 8 ohms is very common for speakers.
A typical amplifier might get unstable in the 1-4ohms range for example.
Are you sure your speaker is 14 ohms 8 watts? The reverse (8 ohms and 14 watts) would seem more likely?

Overdriving speakers isn't a good idea, because at high power levels the sound becomes really distorted. I wouldn't even max out the specified power.

Yes, but you have to take care that the amp is able to drive the resulting impedance. BTW, adding up the dB values of both speakers is done by: sq(SPL1² + SPL2²).

Its a low power amp LM386 but i think that i will take the speakers :D
