Hi, I tried to design my own speaker from scratch and i want to add some features to my speaker such as low power mode. A short description of the speaker is here: the speaker has two drivers - a woofer and a tweeter. The signal passed into the speaker goes through an equaliser, an active crossover, the amplification stage, and then the drivers.
Here is my question. So, in low power mode, I am thinking that the signal will be fed straight to the amplification stage for the tweeter (bypassing the crossover and also switch off the woofer) to save the power used by the woofer. To do this, could I simply connect a switch spanning across crossover to short it out when low power mode is used? Will there be issues caused by this approach?

You're going to switch out the woofer?
You're going to bypass the crossover and send a full range signal to the tweeter?
If I read you clearly, you will end up with no bass/midrange and a damaged tweeter.
To save power, you simply turn the volume down.

Hi, thank you for your response. Yes, I agree with you that it is a stupid idea for feeding all the frequency into tweeter as it will only damage it. However, if instead, can I short the crossover and feed the signal straight to the woofer as woofer is less likely to be damaged? Just to be clear, I am not going for high sound quality in low power mode, it is just a feature that i am thinking of doing.
A tweeter consumes little power so disconnecting it will save you next to nothing, but leave you listening to music which has lost its 'sparkle'.
No one I know has ever considered disconnecting a tweeter or a woofer to achieve a "low power mode".
To be blunt, your idea makes no sense to me.
The way to save power is simply not to play your music too loud.
A loudspeaker only consumes the amount of power you ask the amplifier to deliver to it, and you control that amount with the volume knob.
