They really aren’t, typically. For music production, you want a flat frequency response to enable accurate synthesis and mixing. Speakers designed for media playback normally have super goofy frequency responses that exaggerate the low end and scoop out the mids. Sweep a sine wave from 20hz to 20khz, and I’ll bet it has a bunch of variations in loudness.

The reason that this is bad is that not everyone is going to hear your music on that TV. If you design and mix with that speaker, your music will potentially sound incredibly different on other common playback devices.

For instance, you might drop the subbass a little because the speaker exaggerates it. This sounds great and balanced until you play the song in a car with stock speakers. Now your subbass is starting lower than it would have been on flat speakers, leading to a more tinny and underpowered mix than you would have had on production speakers.

Make and mix on studio speakers, then use consumer speakers as a reference or for everyday listening. It’ll save a lot of mixing headaches.

How are you measuring this? It’s going to be subjective but do you have a reference point?
