Marshall DSL40CR Speaker Upgrade

The Marshall DSL40CR is a beloved amplifier in the world of rock and roll, renowned for its iconic British sound and versatile features. While this amplifier is already capable of delivering impressive tones, some musicians and audiophiles may seek to take their sound to the next level. One way to achieve this is by upgrading the amplifier’s stock speaker. In this article, we will explore the process and benefits of upgrading the speaker in your Marshall DSL40CR amplifier.

Why Consider a Speaker Upgrade?

The stock speaker that comes with the Marshall DSL40CR is designed to offer a balance of sound characteristics that suit a broad range of styles. However, every musician has unique preferences, and a speaker upgrade can help tailor your amp’s sound to your specific needs. Here are some reasons to consider a speaker upgrade:

  1. Tonal Enhancement: Upgrading the speaker can significantly influence the amplifier’s tonal characteristics, allowing you to shape your sound according to your musical style and taste.
  2. Improved Clarity: A high-quality speaker can provide better articulation and clarity in your guitar tone, making your playing more distinct and expressive.
  3. Enhanced Projection: Some speakers offer improved projection, ensuring your sound reaches the audience more effectively, whether you’re playing in a studio, a small club, or a large venue.
  4. Increased Volume: Certain upgraded speakers can handle higher power levels, enabling you to crank up the volume without sacrificing sound quality or risking speaker damage.

Choosing the Right Speaker

Selecting the right speaker for your Marshall DSL40CR is a crucial step in the upgrade process. Here are some factors to consider:

  1. Speaker Size: The DSL40CR typically accommodates a 12-inch speaker. While you can experiment with different sizes, sticking to this size ensures compatibility.
  2. Wattage Rating: Ensure the new speaker can handle the amplifier’s power output. A speaker rated slightly above the amp’s wattage can provide headroom and prevent speaker damage.
  3. Tonal Characteristics: Different speakers offer varying tonal qualities, such as warmth, brightness, or a balanced sound. Consider your preferred genre and the sound you want to achieve when choosing a speaker.
  4. Speaker Brand: Reputable speaker brands like Celestion, Eminence, and Jensen offer a range of options to suit different preferences.

Installation Process

Upgrading the speaker in your Marshall DSL40CR may require some technical know-how. Here’s a general overview of the installation process:

  1. Safety First: Always ensure the amplifier is unplugged from the power source before starting any modifications.
  2. Remove the Old Speaker: Carefully remove the old speaker by unscrewing it from the amplifier’s cabinet. Take note of how the wires are connected, as you’ll need to replicate this with the new speaker.
  3. Install the New Speaker: Secure the new speaker in place using the provided screws. Ensure it is firmly mounted, and the wires are connected correctly.
  4. Test the Amplifier: Before fully reassembling the amplifier, test it to ensure the new speaker functions correctly and produces the desired tonal improvements.
  5. Reassemble the Amplifier: Once you’re satisfied with the new speaker’s performance, reassemble the amplifier’s cabinet, making sure all components are securely in place.


A speaker upgrade for your Marshall DSL40CR amplifier can be a rewarding endeavor, allowing you to fine-tune your tone and enhance your overall playing experience. By selecting the right speaker and following the installation process carefully, you can achieve the sonic improvements you desire, whether you’re a gigging musician or a home studio enthusiast. Experimentation and customization are key to unlocking the full potential of your amplifier’s sound.
