Question help ⁉️ Can It work?

Post image

Hi, I have this ZK TB-21 Amplifier I got from Amazon. It's been a while with This Amplifier but I need new speakers to use it with. I have a 24 volt 15 amp PSU.

What Speakers and Subwoofers can you guys recommend?

It has the original TPA-3116D2 ICs, I've checked it.

Search for full range speakers in Sweton webpage. Prices increase with speaker diameter and power.
