The Park Audio L-Set 151 BT speaker system set includes one active speaker (L151BT) and one passive (L151). The total power output of the set is 700 W, with a maximum sound pressure level of 126.5 dB, making it suitable for medium and large venues.
The frequency range of 47 Hz to 18 kHz ensures clean and detailed sound across both low and high frequencies. Both cabinets feature a trapezoidal shape with bass reflex acoustic design for deeper bass response. For convenient mounting, each speaker includes six M10 mounting points and a 35 mm flange for stand installation. The system connects quickly using a single cable.
The speakers are two-way designs equipped with Italian LAVOCE Italiana drivers: a 15" low-frequency driver with a 2.5" voice coil and a 1" high-frequency driver. The dispersion is 90° horizontally and 40° vertically.
The L151BT features a Class D amplifier delivering 2 x 350 W RMS at 4 ohms. The rear panel includes two 1/4" TRS mic inputs (switchable to line mode), two RCA line inputs, and two 1/4" TRS line inputs. Each input type has individual level controls, along with a three-band EQ for microphone inputs.
Input sensitivity: mic – 3 mV (MIC mode) or 250 mV (LINE mode), TRS line – 775 mV, RCA – 250 mV. The system offers a high signal-to-noise ratio: up to 98 dB for line inputs and 94 dB for mic inputs, ensuring clean, noise-free audio.
Bluetooth 4.1 (Class 2) enables wireless audio streaming with A2DP 1.2 profile support and SBC and AAC codecs. Effective range is up to 10 meters with a clear line of sight.
The amplifier is cooled via forced ventilation, ensuring reliable performance even during long, high-volume use.
