Without a horn, the compression driver will not be able to project the sound as well, and it will also be more susceptible to damage.
That said, there are some cases where it may be necessary to use a compression driver without a horn, such as in a very small speaker system or in a situation where the horn would be too large or bulky.
If you do need to use a compression driver without a horn, there are a few things you can do to mitigate the risks:
* Use a high-quality compression driver designed to be used without a horn.
* Make sure the compression driver is properly mounted and secured.
* Avoid using the compression driver at high volumes.
* Monitor the compression driver for any signs of damage, such as overheating or rattling.
