StudioMaster V218S Dual 18-Inch 2000W RMS Passive Subwoofer

The StudioMaster V218S is a professional dual 18-inch passive subwoofer from the StudioMaster Line Array Sub Bass Series, specifically designed for professional stage sound systems, concerts, large auditoriums, bars, clubs, DJ performances, and high-power PA applications requiring deep, powerful, and high-output bass reproduction.

Equipped with two high-performance 18-inch LF drivers featuring 4-inch voice coils, the StudioMaster V218S delivers 2000W RMS, 4000W Program, and up to 8000W Peak power handling. Combined with a frequency response of 32Hz–200Hz and a maximum sound pressure level of 138dB, this subwoofer provides exceptional low-frequency performance for large-scale live events and professional sound reinforcement.

Featuring a dedicated bass reflex enclosure, premium Birch Plywood construction, and compatibility with StudioMaster V10, V310, and V312 line array systems, the V218S is an ideal subwoofer solution for event production companies, touring sound systems, and professional audio installations.

1. Dual 18-Inch Configuration – Deep, Powerful, and Impactful Bass

The StudioMaster V218S features two 18-inch low-frequency drivers equipped with 4-inch voice coils, delivering high-performance low-frequency reproduction.

Its dual 18-inch configuration increases the total cone area and air displacement capability, helping produce powerful, deep, and impactful bass.

The two LF drivers are designed to meet the demanding requirements of professional sound reinforcement systems, particularly applications requiring high-energy bass reproduction such as electronic music, DJ performances, live bands, and concerts.

With its dual 18-inch driver configuration, the V218S significantly enhances the low-frequency foundation of a sound system, delivering fuller, tighter, and more energetic bass performance.

2. 2000W RMS Power – High-Performance Operation

The StudioMaster V218S offers powerful performance with three specified power ratings:

• 2000W RMS (Continuous): Continuous power handling.
• 4000W Program: Program power handling.
• 8000W Peak: Maximum peak power handling.

With 2000W RMS power handling, the subwoofer is capable of delivering substantial low-frequency reinforcement for professional stage and event sound systems.

Its 4000W Program and 8000W Peak ratings demonstrate its ability to handle higher transient signal levels under appropriate operating conditions.

The V218S is a passive subwoofer and therefore requires a compatible professional power amplifier. To achieve optimal performance, sound engineers should select an amplifier capable of delivering suitable power at the speaker's 4Ω impedance and configure appropriate signal processing and limiting to protect the system.

3. Frequency Response: 32Hz–200Hz – Deep and Full Low-Frequency Reproduction

The StudioMaster V218S features a frequency response range of 32Hz to 200Hz, focusing on the low-frequency and sub-bass spectrum.

Its ability to reproduce frequencies down to 32Hz allows the subwoofer to deliver deep bass extension, creating a powerful and immersive musical experience.

The upper frequency limit of 200Hz also provides flexibility when integrating the V218S with compatible line array and full-range speaker systems, allowing sound engineers to achieve appropriate transitions between low-frequency and mid/high-frequency sections.

This capability is particularly important for live stages, concerts, and large-scale PA systems where bass performance must deliver depth, impact, and strong sound projection.

4. 138dB MAX SPL – Impressive Maximum Sound Pressure Level

One of the major advantages of the StudioMaster V218S is its maximum sound pressure level of up to 138dB.

This high SPL capability demonstrates its ability to deliver powerful bass output, making it suitable for large venues and high-volume live performances.

Combined with a sensitivity rating of 99dB ±3dB (1W/1m), the V218S provides effective acoustic output from the power supplied by the amplifier.

As a result, it is well suited to professional sound reinforcement systems requiring high output, powerful performance, and reliable bass reproduction during live events.

5. 4Ω Impedance – Integration with High-Power Amplifiers

The StudioMaster V218S features a nominal impedance of 4Ω, making it suitable for professional power amplifier systems designed to operate at the corresponding load.

Its 4Ω impedance provides sound engineers with additional flexibility when designing amplification configurations and integrating multiple subwoofers into professional PA systems.

When connecting multiple speakers, the total system impedance must be calculated carefully, and amplifier load compatibility must be verified to ensure reliable operation.

The subwoofer is equipped with professional NL4 Speakon connectors, providing secure connections and convenient integration into professional stage sound systems.

6. Bass Reflex Line Array Design – Optimized Low-Frequency Performance

The StudioMaster V218S features a dedicated bass reflex enclosure designed for professional line array subwoofer applications.

Its bass reflex architecture helps optimize low-frequency reproduction, enhance bass energy, and improve overall acoustic efficiency.

The enclosure is engineered for professional sound reinforcement applications, allowing the V218S to integrate effectively with line array speaker systems in large stages and auditoriums.

When properly positioned and configured, multiple V218S modules can be combined to expand low-frequency coverage and accommodate different audience sizes and venue requirements.

7. Premium Birch Plywood Cabinet – Built for Professional Touring Applications

The StudioMaster V218S enclosure is constructed from premium Birch Plywood, a material widely used in professional stage loudspeakers due to its rigid structure and excellent durability.

The cabinet features a protective coating designed to resist scratches and moisture, helping improve durability during transportation, installation, and frequent professional use.

Its robust construction helps minimize unwanted cabinet vibration and supports consistent acoustic performance during high-power operation.

In addition, recessed handles are integrated into the enclosure to make transportation, positioning, and handling more convenient for mobile sound reinforcement systems.

8. NL4 Speakon Connectivity – Professional Connection Standard

The StudioMaster V218S is equipped with professional NL4 Speakon connectors, meeting the connectivity requirements of professional stage and PA sound systems.

The Speakon connection standard provides secure cable connections, reduces the risk of accidental disconnection, and supports reliable signal transmission during operation.

This widely adopted connection format makes system installation, equipment removal, and maintenance more convenient for professional audio applications.

9. Integration with StudioMaster Line Array Systems

The StudioMaster V218S is designed to work with professional StudioMaster line array systems, particularly the following models:

• StudioMaster V10.
• StudioMaster V310.
• StudioMaster V312.

When combined with compatible line array speakers, the V218S handles low-frequency reproduction while the line array modules reproduce the midrange and high-frequency sections.

This combination creates a powerful and balanced full-range sound reinforcement system suitable for large-scale live performances and professional events.

Sound engineers can deploy multiple subwoofer modules to increase bass output according to stage dimensions, audience capacity, and specific event requirements.

10. Applications of the StudioMaster V218S

With its dual 18-inch configuration, 2000W RMS power handling, 138dB maximum SPL, and professional line array design, the StudioMaster V218S is suitable for a wide range of professional audio applications:

• Large-scale professional stage sound systems.
• Concerts and live performances.
