I owned a pair of TC50's from 1990 through 1993. I bought them because I moved into a small apartment.
I enjoyed them and they served me well. They are not well extended in either direction but what is there is fine. They have a good upper bass, which can give you a feeling of what is below. I think it is generous to say you can get 60hz solidly from them but I never measured them
The midrange and sound stage is what made them enjoyable. Also, although they go south after 16,000 they have an Audax soft dome which is smooth. They won't play at head banging levels but can handle 90hz or so in the right room. They can tend to compress if driven too hard.
Finally, both drivers are hard wired with no protection. So, if you are not feeding them good clean power you can distroy the drivers. However, they were out sourced and easy to replace.
One more thing is that they do need power. They are not they most sensitive speaker. I would say at least 100 watts with current.
