HESU Demon 12″ Speaker


When we started in 2010 we didn't know where this journey will took us.

Now with almost 2000 cabinets done by us we have huge experience with different kind of guitar and bass speakers.

In 2013 we started project called “Demon” – whole idea was to make the best possible guitar speaker without any compromises, with best quality components.

Built to meet the demands of high gain amplifiers but not only.

Clean sounds are true across the lows, mids and highs, with just enough upper-mid chime and HF sparkle to add clarity and definition.

It's an ideal speaker to bring drive and definition to modern tube amps.
