The Arcadia Model 30 is a handcrafted 1930s‑style cathedral radio reimagined as a modern Bluetooth speaker. Its arched silhouette, Deco flourishes, and warm amber window capture the romance of early broadcast design, while the internal architecture delivers clean, room‑filling audio through a pair of tuned full‑range speakers and a carefully balanced enclosure.

Inside the vintage shell lives a fully modern acoustic core: efficient Class‑D amplification, clean Bluetooth connectivity, and a resonance‑optimized chamber that produces surprising warmth and clarity for its size. Every curve, grille, and leaf motif is modeled after period originals, giving it the presence of an heirloom object with the convenience of a contemporary wireless speaker. This is not a novelty piece—it’s a premium sound system disguised as a 1930s radio.
