## Customer Reviews

### ⭐⭐ 2.0 out of 5 stars







  
  
    Wrong choice
  

*by R***K on Reviewed in the United States on May 31, 2014*

The  speaker just wouldn't work with my system and there were no instructions nor hook-up hints to follow. It is probably my fault but I wouldn't know without the tech info.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Check input requirements
  

*by P***N on Reviewed in the United States on December 2, 2014*

Reading the first review, it occurred to me that these are 70v speakers, designed and wired for multiple speaker hookup. It would require an amplifier with 70v output to make them work. However, if you can get inside the unit you could bypass the transformer and wire directly to the speakers. I like them for size and style, but I'll need to purchase one to see if they can be reconfigured for standard 8 ohm input. 4" and 8" plus black gives them versatility.
