From PMC
The twenty5.21i is the entry point into PMC's twenty5i standmount range, a compact cabinet built to sit on dedicated stands or bookshelves.
It runs PMC's ATL bass loading, aimed at giving the small cabinet impact closer to a much larger speaker.
It's built for smaller rooms and works as a compact two-channel pair or as part of a larger multichannel system.
