Review on Infinity REF1000S Shallow Mount Subwoofer by Dawn Miller

I bought this 10 inch subwoofer last year on August 30th 2019 because it is switchable. He worked for 10 months. very good with outstanding bass, but from the end of may 2020 i had problems with it, the subwoofer started to break at high volume and finally stopped working on 6/1/2020. An internal connection problem was that. The 4 ohm speaker was blown but when I switched it to 2 ohms it worked again? decided to buy a Pioneer 12" Downward Fire subwoofer as a replacement
