Fantastic bass subwoofer great range of power

Great design and sound

I bought this to fit in my van under the front seat.It was really easy to fit and the build quality is excellent. No plastic of wood casing here, it is a cast metal enclosure and very solidly built.The sound quality is also excellent. I have my remote volume set to 50% and there's plenty of bass for me at that level.

Perfect for small car set up

The media could not be loaded. Very solid ,well made compact subwoofer. Wasn’t expecting a clean and clear sounding bass , However this subwoofer went beyond expectations. If you’re looking for a clean and clear mid bass, this is a must have system.
