Is the Yamaha CXS15 MK3 an active or passive subwoofer?

The Yamaha CXS15 MK3 is a passive subwoofer. This means it does not have a built-in amplifier and requires an external power amplifier to function.

What is the driver size used in the CXS15 MK3?

The unit features a 15-inch low-frequency driver. This driver is equipped with a 3-inch voice coil to handle high power levels and maintain control over the cone movement.

What type of enclosure does this subwoofer use?

It uses a band-pass enclosure design. This design helps to produce a more focused and controlled bass output by filtering the acoustic output through internal chambers.

What is the lowest frequency the CXS15 MK3 can reach?

In its standard configuration, the frequency response goes down to 40 Hz. However, when used in 'extended mode,' the frequency response reaches down to 35 Hz.

What material is the cabinet made from?

The cabinet is constructed from robust plywood. This is chosen for its durability and better acoustic properties compared to lightweight plastic cabinets.

What kind of finish is applied to the exterior?

The cabinet features a durable polyurea finish. This coating is designed to be highly resistant to scratches and damage, making it ideal for professional use and travel.

Does the CXS15 MK3 require a crossover?

Yes, as a passive subwoofer, it typically requires an external crossover or a power amplifier with built-in DSP to ensure only low frequencies are sent to the driver.

Can I mount a pole on top of this subwoofer?

Yes, the CXS15 MK3 includes mounting options that allow for a standard speaker pole to be inserted. This enables the mounting of full-range speakers like the RCF ART series or Yamaha top boxes above it.

How much does the Yamaha CXS15 MK3 typically cost?

The typical price for this model is approximately £1,049. Prices may vary slightly depending on the retailer and shipping costs.

Who is the primary target audience for this subwoofer?

It is designed for professional sound engineers, venue installers, and touring PA companies. It is particularly suited for those who already use external amplification racks.

How does it compare to the QSC KLA181?

The QSC KLA181 is an 18-inch active subwoofer, whereas the Yamaha CXS15 MK3 is a 15-inch passive unit. The Yamaha is more compact but requires external power, while the QSC is larger and self-powered.

Is this subwoofer suitable for home use?

While it can be used anywhere, it is a professional PA component designed for high-volume environments. For home settings, smaller active units like the AVCOM 8-inch walnut sub are often more aesthetically and acoustically appropriate.

Yamaha CXS15 MK3 Passive Subwoofer

The Yamaha CXS15 MK3 is a professional 15-inch passive PA subwoofer designed for high-output low-frequency reinforcement in live sound and fixed installations. Featuring a band-pass enclosure and a durable polyurea-coated plywood cabinet, it provides controlled bass response down to 35 Hz in extended mode.

Overview

The Yamaha CXS15 MK3 is a dedicated passive subwoofer engineered to provide authoritative low-end support for professional public address systems. Unlike active units that include internal amplification, the CXS15 MK3 requires external power, allowing for centralised rack management in complex setups. It is built around a high-excursion 15-inch woofer and utilizes a band-pass design to maximise efficiency and focus within the low-frequency spectrum.

Design and Construction

The unit is housed in a robust plywood cabinet, a material preferred in professional audio for its acoustic neutrality and structural integrity compared to plastic alternatives. The exterior is treated with a heavy-duty polyurea finish, providing significant resistance to impacts, scratches, and environmental wear during transport or long-term installation. The design includes integrated mounting options and practical connectivity to facilitate integration into standard PA arrays.

Acoustic Performance

At the core of the CXS15 MK3 is a 15-inch driver equipped with a 3-inch voice coil, capable of delivering precise and punchy bass. The standard frequency response starts at 40 Hz, which is sufficient for most musical applications. However, the system features an 'extended mode' that allows the sub to reach down to 35 Hz, providing the extra depth required for electronic music or cinematic sound reinforcement where sub-bass content is critical.

Target Applications

This subwoofer is suited for users who require a high-performance, non-powered low-frequency solution. Common applications include:

Live Sound Reinforcement: Providing the 'thump' for bands and mobile DJs.
Permanent Installations: Ideal for clubs, theatres, and houses of worship where amplifiers are kept in a separate machine room.
Professional PA Hire: Its durable construction makes it a reliable choice for rental inventories.

Comparison with Alternatives

When compared to active alternatives like the QSC KLA181 or the RCF ART 735-A MK5, the CXS15 MK3 offers the advantage of lower weight (due to the absence of an internal amp) and simpler maintenance for large-scale installs. While smaller units like the SubZero C10M or AVCOM 8-inch subwoofers offer portability, they lack the 15-inch driver surface area and the specific band-pass tuning of the Yamaha, which is necessary for high-SPL professional environments.
