Rockville RX230 2-Way Stereo / 3-Way Mono Crossover - Precise Live

Our review of the Rockville RX230 finds it to be a practical, rack-mountable crossover for DJs, live sound techs, and home audio users who need reliable frequency separation without fuss. The RX230's biggest strength is straightforward, professional signal control: switchable 2-way stereo or 3-way mono operation combined with balanced XLR I/O and steep 24 dB/octave filters makes it easy to dial in clean mids, highs, and subs for a range of venues. For anyone who wants predictable, adjustable crossovers and a dedicated subwoofer feed, this unit delivers clear benefit.

Key Features

• Switchable 2-way/3-way: Lets the operator choose 2-way stereo or 3-way mono operation to tailor speaker and subwoofer setups for live or studio use.
• Balanced XLR connectivity: Provides professional inputs and outputs for low-noise, reliable connections to mixers, amps, and powered speakers.
• Adjustable crossover ranges: Main crossover can be set between 100 Hz and 1 kHz with a x10 option up to 10 kHz, so mids and highs are precisely placed for different speakers.
• Dedicated subwoofer control: Subwoofer output includes an adjustable crossover from 30 Hz to 200 Hz and a gain control from -6 to +6 dB to tune low-end balance.
• Advanced filtering: 24 dB/octave filter slopes deliver steep, accurate separation so each driver receives the intended frequency band with minimal overlap.

Who It's For

The RX230 suits DJs, small live sound operators, and project studio owners who need a compact, rackable crossover with professional XLR I/O and flexible crossover points. It is particularly useful when a dedicated subwoofer output and precise mid/high control are required for a PA or rehearsal rig.

Less appropriate for those needing digital signal processing, built-in EQ presets, or a completely silent noise floor; if low-level hiss or occasional pops would be unacceptable in a critical listening room, audition the unit first to confirm tolerance of its noise characteristics.
