Remo's Dorado Cajons are designed and hand crafted in California using Birch plywood, and high quality compression springs with over 400 coils. The Dorado Cajon takes it back to the traditional Fixed Face Plate construction. This process seals the drum completely and enables the bass tones to resonate naturally. This is only possible with Remo Patent Pending, Quick Wedge Snare System. The Quick Wedge Snare System is designed to give you an extraordinary sound, with precisely measured Coil Spring length for the perfect tension that create an ideal bass and spring separation for a superior quality sound.
