Which word to use when speaker sound is not working properly

I have a malfunctioned speaker, its sound does not come out normally but is like being stuck, which word(s) could I use to describe a speaker with defected sound? Thanks in advance.

I would be tempted to describe the sound the speaker makes. There are lots of ways a speaker could be broken, The sound could be:

• tinny
• cracked
• distorted
• warped
• garbled

Consider:

• choppy, “Discontinuous, intermittent. [eg] The sound is choppy in this video”
• staticky, “Resembling or containing static [eg] The connection was staticky”
• buzzing, “The sound produced by something that buzzes [eg] I can hear buzzing coming from the television”

Three possibly-relevant ELU questions are Can sound be "blurry?", What word can I use for unclear music?, and Term for buzzing or hissing sound often created by vibration. In an answer to that last, I wrote:

An webervst.com spterm.html webpage defines numerous terms for speaker-related distortions, including Boomy, Breakup, Buzz, Rattle, Cone Cry, Ghost Notes, Edge Yowl, Crunch, Damping, Diffused, Fizz, Flabbing, Farting Out, Harsh, Honking, Muddy, Peaky, Presence Notch, Voice Coil Rub. The web page attributes buzz and rattle to speaker damage, caused for example by exceeding a speaker's power limits.
