Passive acoustic system Park Audio L251-4

The Park Audio L251-4 passive speaker system is designed for professional sound reinforcement on large venues where loud and clear sound is required. The maximum peak sound pressure level is 136 dB, and the system covers a wide frequency range from 44 Hz to 18 kHz.

The L251-4 uses two 15" low-frequency drivers, each with a 500 W power rating, from the Italian brand Lavoce Italiana. The high frequencies are handled by a 1" driver with a 60 W power rating from B&C Speakers, featuring a 1.7" voice coil. Thanks to the 90° horizontal and 40° vertical dispersion angle, the sound is evenly distributed across the space.

The cabinet is made from durable birch plywood. The surface is coated with black water-based polymer paint. The front is protected by a perforated steel grille with a powder-coated finish.

The system uses a bass-reflex design, which allows for deeper and fuller bass. It connects via the standard SpeakON connector, ensuring a reliable connection and ease of use.

The system's total rated power is 1000 W (AES), with a program power of 2000 W. The sensitivity of 100 dB allows the system to achieve high volume levels even with a lower amplifier power. The speaker operates with a 4-ohm impedance. The weight of the system is 45 kg, and its dimensions are 445 x 1065 x 520 mm.
