Classic AlNiCo Vox Tone
12", 40oz AlNiCo magnet. 1-3/4" voice coil, ribbed cone.
As with all Weber speakers, the higher the power rating, the warmer and smoother the speaker.
The 75 and 100 watt models use very high temperature voice coils that are the same weight and mass as the lower power voice coils. That assures good attack and a broad frequency response due to the low weight and mass of the voice coil assembly.
