Can you fix blown speakers?
Usually, it’s impractical to repair a blown speaker, as repairs can often cost more than replacements, but whether you had a car or home speaker fail on you, there are many viable replacements.
How do I stop my speakers from blowing?
Keep the volume on your receiver at least 5-6dB below its max setting. The volume adjustment on most receivers goes from -80dB (mute) to about +16dB (max). By staying below -6dB below that max setting you can typically avoid over-driving the receiver, which could potentially damage your speakers and receiver.
