Akai RPM500 Active Bi-Amplified 5.25” Studio Monitor Speaker

Akai RPM500 Bi-Amplified Studio Monitor

The Akai RPM500 is a professional 5-inch bi-amplified studio reference monitor designed for accurate nearfield audio monitoring in music production, mixing, and recording environments. It delivers a balanced frequency response with controlled bass, detailed mids, and clear high frequencies, making it suitable for critical listening and studio-grade sound evaluation.

Bi-Amplified Class A/B Power System

The RPM500 features a distributed Class A/B bi-amplification system with a total output of approximately 90 watts. This design separates amplification between low and high frequency drivers, ensuring cleaner signal reproduction and reduced distortion during playback.

• 50W dedicated low-frequency amplifier
• 40W dedicated high-frequency amplifier
• Low-distortion Class A/B circuitry for accurate monitoring

5.25-Inch Kevlar Woofer for Tight Low-End

The monitor is equipped with a 5.25-inch Kevlar low-frequency driver, engineered to deliver precise and controlled bass response. Kevlar material helps reduce unwanted resonance, resulting in a tight, articulate low-end that is essential for accurate mixing decisions.

Silk-Dome High-Frequency Driver

For high frequencies, the RPM500 uses a 1.25-inch silk-dome tweeter, providing smooth and detailed treble reproduction. This helps reduce listening fatigue while maintaining clarity in vocals, cymbals, and high-end audio elements.

Proximity Control and Room Tuning

A key feature of the RPM500 is its Proximity Control system, designed to adapt the monitor’s response to different studio environments. This allows users to fine-tune the speaker based on placement and room acoustics for more accurate sound reproduction.

• HF Trim for high-frequency adjustment
• MF Boost for midrange enhancement
• LF Cutoff for low-frequency control
• Proximity Control for boundary and placement compensation

Wide Frequency Response for Accurate Mixing

The RPM500 delivers a frequency response of approximately 50 Hz to 30 kHz, providing a broad and detailed sound spectrum. This allows producers and engineers to hear subtle details in both low and high frequency ranges during mixing and mastering.

Acoustic Design and Build Quality

The cabinet is designed with reinforced construction to minimize resonance and unwanted coloration. A rear-firing bass port enhances low-frequency extension while maintaining clarity and control. Internal shielding and protective circuitry help preserve signal integrity in studio environments.

Connectivity Options

• XLR balanced input
• 1/4" TRS balanced input
• RCA unbalanced input

This flexible connectivity allows integration into professional studios as well as home recording setups.

Ideal Applications

• Music production and audio mixing
• Home and professional recording studios
• Beat making and electronic music production
• Critical listening and sound design
• Post-production and editing workflows

Key Features

• 5.25-inch Kevlar low-frequency driver
• 1.25-inch silk-dome tweeter
• 90W bi-amplified Class A/B power system
