Our vintage-tuned enclosures are perfectly suited for the California Tweed™. Made in Petaluma, California, these open-back cabinets are constructed from Marine Grade, Baltic Birch and feature an all new, rear-mounted speaker from Jensen. Finding a speaker that would translate the California Tweed's touch-sensitive dynamics wasn't easy. After countless samples we finally chose the all-new Jensen BLACKBIRD ALNICO. These two together deliver a toneful American voice.
