Speaker service centers - Q Acoustics Concept 500

I have a pair of Q Acoustics Concept 500 speakers that I purchased five years ago. After contacting customer service and describing the issue, I was informed that the tweeter likely needs to be replaced.

Unfortunately, the speakers are no longer under warranty, so the manufacturer is unable to fix them. However, they are willing to ship me a replacement tweeter for a cost.

I am based in New York, and Q Acoustics does not have an authorized service center here.

Question: Are there any reputable speaker service centers in or around New York that can help me replace the tweeter and service the speakers?
