2 way design
On/in wall easy mounting
High detailing and loudness from a very compact source
2 colours: Black/ White
The 502 is a 2 way design that is slightly more powerful and louder than the 501. While retaining the great quality IWO sound, the 502 will allow you to get a better overall loudness than the 501. Importantly since it has a higher power handling, there is better integration with the subwoofer also.
