Peavey SP 4XT is a versatile sound reinforcement enclosure suitable for a wide range of applications, including public address, musical playback, and monitoring systems. It features two 15-inch Black Widow woofers for powerful low-end response and a 22XT titanium compression driver coupled to a CH-941 constant-directivity horn for clear and articulate highs. The SP 4XT's two-way passive crossover ensures optimal time alignment between the drivers, resulting in a smooth and cohesive sound from 48 Hz to 17 kHz.
