Know before you buy
The digital Finite Impulse Response (FIR) filter ensures precise time alignment between the woofer and tweeter. This results in superior sound positioning and a more accurate stereo image compared to traditional analog crossover networks.
Yes, the 5.2-inch woofer and 50Hz - 20kHz frequency response make them well-suited for smaller production spaces. Their compact footprint and precise frequency controls allow you to tune the output to fit the acoustics of a smaller room.
The PX-5 features a 44-step digital control system for both volume and trim levels. This allows for highly precise, repeatable adjustments that are more accurate than traditional analog knobs.
Yes, the PX-5 includes an auto-standby function that detects when the signal is inactive to conserve power. It also features an auto-operation function that wakes the speaker when it receives an input signal.
The monitors are versatile, offering XLR, 1/4-inch, and RCA inputs. This allows you to connect them directly to professional audio interfaces, mixers, or consumer-grade playback devices without needing extra adapters.
Aramid fiber is exceptionally rigid and lightweight, which helps the woofer maintain its shape during rapid movement. This rigidity minimizes distortion and ensures that low-frequency reproduction remains tight and accurate even at higher volumes.
