PRORECK Dual 15 vs 18 Inch Spec Comparison
System Type
The PRORECK Dual 15-Inch Line Array PA System is a complete all-in-one kit. It includes two 15-inch subwoofers, four 6.5-inch line array speakers, stands, and cables. The PRORECK 3500W P.M.P.O 18-inch unit is a two-piece set with an active subwoofer and a 15-inch DSP PA speaker. You get fewer components with the second option, as it does not include stands or array speakers. The first system offers a more comprehensive package for immediate setup.
Woofer Size
You must decide between larger drivers for bass or a balanced full-range approach. The PRORECK Dual 15-Inch system uses two 15-inch woofers for its subwoofers. The PRORECK 3500W P.M.P.O 18-inch model features a single 18-inch low-frequency driver in its powered subwoofer. The larger 18-inch cone typically moves more air for deeper bass response. The dual 15-inch setup provides substantial low-end output across two cabinets. Your choice depends on whether you prefer the sheer size of the 18-inch driver or the distributed output of the dual 15s.
Connectivity
Both systems offer robust input and output options for various audio sources. The PRORECK Dual 15-Inch Line Array supports Bluetooth 5.0, USB, SD card playback, two XLR mic jacks, stereo RCA, and a 3.5mm AUX input. It also includes balanced XLR outputs for daisy-chaining. The PRORECK 3500W P.M.P.O 18-inch system provides balanced XLR combo inputs, stereo RCA, 1/4" TRS, and AUX IN. It features filtered XLR outputs between 100Hz and 20KHz. The first system adds wireless streaming and digital media playback, which the second lacks.
Sound Processing
Each unit handles audio tuning differently. The PRORECK Dual 15-Inch Line Array includes a sub crossover, sub phase switch, echo control, and talkover function. These controls help you manage vocal clarity and bass integration. The PRORECK 3500W P.M.P.O 18-inch model features a built-in 3-channel mixer with advanced DSP (Digital Signal Processing). This allows for precise sound customization and input management. The DSP in the second unit offers professional-grade control, while the first relies on dedicated hardware switches for phase and echo.
Form Factor
The physical design impacts how you deploy the sound. The PRORECK Dual 15-Inch Line Array uses a line array configuration with four 6.5-inch speakers mounted on poles. This design provides wide coverage and uniform sound distribution for large audiences. The PRORECK 3500W P.M.P.O 18-inch system uses a traditional stage monitor or PA speaker shape for the 15-inch driver. It is paired with a separate subwoofer. The line array setup is better for covering large areas evenly, while the traditional speaker offers a more compact footprint.
