The closest thing to the classic JBL D120F speaker which was so prominent in classic vintage deluxe and tweed amps. Weber have gone out and make there version with a 40oz AlNiCo magnet, boosted with ceramic, 60 watt, 2" voice coil, curved cone. 

Its loud, smooth, uncoloured, compressed at higher volumes. Some say its the ultimate clean-tone. 

It runs a large H screen dome for more warmth. It Allows the high end to be present but not overbearing. Good for warmer yet articulate cleans, but also moderate overdrive.

Best use in a rich, crisp, un distorted range of guitar playing.

Kick back and enjoy the pure clean waves of the California sound.
