In response to popular demand, here’s a ceramic magnet Tone Tubby with a 25 watt power rating. This speaker is a fantastic and very affordable choice for lower powered amps. The San Rafael has more compression and is a bit looser in the bottom end than the higher-powered 40/40. Get the classic Hempcone sound at lower volumes.
