Marine audio built to last
The TS-MR2040 is designed to deliver dynamic sound outdoors and on the water. Heavy-duty construction resists water, corrosion and heat throughout.
The water-resistant IMPP (Injection Moulded Polypropylene) composite cone provides outstanding mid-bass response and holds up against salt water, humidity and extreme heat.
An elastomer surround resists colour fading or running over time. The Acrylonitrile-Elastomer Styrene (AES) glass fibre reinforced basket protects the magnetic circuit, and the pure white AES grilles resist fading and yellowing caused by direct sunlight and heat.
Gold tinsel wire and gold-plated wire terminals are used throughout to prevent corrosion and maintain a clean audio signal.

Who it suits

Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Treating the door skin matters as much as the speaker. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Are the Pioneer TS-MR2040 speakers suitable for boats?
A: Yes. They have a water-resistant IMPP composite cone, an elastomer surround, a glass fibre reinforced AES basket, UV-resistant white AES grilles and gold-plated terminals to resist salt water, humidity, heat and corrosion.
Q: What tweeter does the TS-MR2040 use?
A: A 20mm PI dome tweeter with a reflex horn, mounted coaxially in the 20cm woofer.
