Description
MB Quart DS2-254 Discus 10 Inch 600W Dual 4 Ohm Voice Coil Shallow Mount Subwoofer
A high-performance 10 inch shallow mount subwoofer from the MB Quart Discus series, delivering 300W RMS in less than 3 inches of mounting depth for powerful bass in space-restricted installations.
Product Overview
The MB Quart DS2-254 Discus is a 10 inch shallow mount subwoofer built for car audio enthusiasts who demand genuine low-frequency performance without sacrificing cargo space or requiring deep enclosure volumes. With a mounting depth of less than 3 inches, the DS2-254 opens up installation possibilities in vehicles where a full-depth subwoofer simply will not fit, including sedans, SUVs, utes, and vans with limited boot depth.
Handling 300W RMS and 600W peak through its dual 4 ohm voice coil configuration, the DS2-254 gives installers the flexibility to wire the subwoofer to a 2 ohm or 8 ohm final impedance depending on amplifier requirements. The lightweight woven fiber cone and dust cap deliver fast transient response with excellent rigidity, while the vented aluminium voice coil former efficiently dissipates heat to maintain performance in the tight thermal environment of a small enclosure. The MB Quart poly cotton spider resists softening and sagging over time, ensuring long-term power handling with minimum distortion. Finished in red with nickel-plated stainless push and insert terminals, the DS2-254 combines striking aesthetics with premium build quality.
Features & Benefits
Shallow Mount Design Under 3 Inches: With a mounting depth of just 3.00 inches, the DS2-254 installs in enclosures and vehicle locations where full-depth subwoofers cannot, making it ideal for spare tyre wells, under-seat enclosures, and shallow custom builds without compromising bass output.
Dual 4 Ohm Voice Coil Configuration: The dual 4 ohm DVC design gives installers the flexibility to wire the subwoofer to a 2 ohm load (parallel) or an 8 ohm load (series), allowing optimisation to match the amplifier's rated output impedance for maximum power transfer and efficiency.
Lightweight Woven Fiber Cone: The woven fiber cone and dust cap delivers a superior balance of low mass and structural rigidity, enabling faster transient response and tighter, more accurate bass reproduction compared to heavier cone materials.
Vented Aluminium Voice Coil Former: The 2.5 inch high-temperature voice coil is wound on a vented aluminium former that actively dissipates heat during high-power operation, maintaining thermal stability in small enclosure volumes where heat buildup can degrade performance.
MB Quart Poly Cotton Spider: The specialised poly cotton spider resists softening and sagging over extended use, preserving the subwoofer's mechanical integrity and ensuring consistent power handling and low distortion throughout the product's lifespan.
Stainless Nickel-Plated Push and Insert Terminals: Push and insert terminals provide a secure, corrosion-resistant electrical connection with a high-end fit and finish, simplifying installation while ensuring reliable long-term connectivity.
UV-Treated Foam Surround: The UV-treated foam surround resists sun fading while maintaining flexibility over time, protecting the subwoofer's performance and appearance in vehicles exposed to high sunlight and temperature variation.
Powder Coated Stamped Steel Basket: The robust powder coated stamped steel frame provides a solid foundation for the motor system and moving parts, supporting accurate bass output and durability across a wide range of installation and operating conditions.

Frequently Asked Questions
What is the wiring impedance of the DS2-254 DVC subwoofer?
The DS2-254 features two 4 ohm voice coils. Wiring the coils in parallel produces a 2 ohm final impedance, while wiring them in series produces an 8 ohm final impedance. Choose your wiring configuration based on your amplifier's rated stable impedance to achieve the best power output and efficiency from your system.
What enclosure type does the DS2-254 work best in?
MB Quart recommends a sealed enclosure for the DS2-254. Due to its shallow mount design, the subwoofer is well suited to compact sealed boxes, spare tyre enclosures, and underseat enclosures where mounting depth is limited. Refer to the MB Quart manual for specific enclosure volume recommendations.
What amplifier power is recommended for the DS2-254?
The DS2-254 handles 300W RMS continuously. For optimal performance, pair it with a monoblock amplifier capable of delivering 250W to 300W RMS at your chosen wiring impedance (2 ohm or 8 ohm). Avoid significantly underpowering or overpowering the subwoofer to maintain performance and protect against damage.
How shallow is the DS2-254 mounting depth?
The DS2-254 has a mounting depth of 3.00 inches, making it one of the shallower 10 inch subwoofer options available. This allows installation in spare tyre wells, underseat enclosures, and shallow custom builds where full-depth subwoofers with 5 to 7 inch mounting depths cannot fit.
What cut-out size does the DS2-254 require?
The DS2-254 requires a cut-out diameter of 9.06 inches. Always measure and confirm the available cut-out space in your chosen enclosure or vehicle location before installation to ensure correct fitment. The outside diameter of the subwoofer is 10.2 inches.
