DB Unlimited's 67 series waterproof speakers are specifically designed and manufactured to deliver the outstanding performance users expect from DB Unlimited while also providing IP67 protection to user's products. The 67 series survives and continues to operate normally after being exposed to dust, splashes, spills, sprays and even submersion when properly sealed into users housing.

The 67 series' starting line-up includes 4 Ω and 8 Ω speakers, ranging from 18 mm to 44 mm with a broad range of power handling capability. They come in round, rectangle, and oval frames; with and without mounting flanges. Supporting frequencies as low as 300 Hz, DB Unlimited's 67 series speakers are suitable for virtually every audio application requiring water resistance.
