The Discus DSC4125, like the full Discus line of car audio, are perfect when power and control are needed to fine tune system design. The Discus amplifiers feature Class A/B topology with built-in crossovers for complete control of all four channels. Additionally, the Discus four channel amplifiers can be configured as 3-way amplifiers - a pair of channels for stereo speakers and a pair of channel bridged for a mono subwoofer or subwoofer system.

These German-designed speakers are technically sophisticated and produce great sound quality while being an affordable first step into the high-end car audio brand MB Quart. MB Quart Discus Speakers are the perfect accompaniment for any MB Quart system due to the engineering of the WideSphere™ titanium dome tweeter. The crossover on the DSH216 features a -3dB/0dB/+6dB tweeter attenuation/accentuation so you can tone it up or down depending on your musical tastes.

MB Quart Discus 6x9" coaxial with 20mm (.75") aluminum dome tweeter on silk surrounds, mica filled poly cone and proprietary deep drawn heavy gauge steel baskets with Euro-DIN fitment.

Features & Benefits


  • Class/Topology
    Designed specifically by MB Quart engineers to deliver high sound quality with minimal distortion while developing plenty of power
  • Power Supply
    PWM (Pulse Width Modulated) MOSFET power supply delivers maximum power
  • Indicators
    LED power and protection indicators
  • Crossover / Signal Shaping
    The system can be fine-tuned to maxximize power in the subwoofer system
  • Illumination
    The MB Quart red chicklet in the logo lights up to easily identify your amplifier as a top-of-the-line, advanced technology choice


  • WideSphere™ Sound 
    WideSphere technology was developed for the world renowned ‘Q’ Series Speakers. However, this incredible technology is now available in the Discus series. WideSphere technology allows the tweeter to develop a wider listening area for off-axis listening. This is also referred to as the “sweet spot” in the sound stage
  • Titanium Dome Tweeter
    Impact-resistant tweeter elements produce better off-axis listening, great sound quality and have increased reliability
  • 30mm Tweeter
    30mm tweeter produces clear highs while handling plenty of power without harsh sound
  • Phase Lens
    The MB Quart phase lens was developed over a decade for WideSphere™ technology tweeters to dramatically enhance the sound state of off-axis listening
  • Polypropylene Cones
    Polypropylene cones are lightweight for speed and very rigid for deep bass tones with musical midrange frequencies
  • Braided Tinsel Leads
    Braided tinsel leads are highly conductive while remaining flexible during high power applications
  • Pure Copper Voice Coil
    Pure copper voice coil creates a strong magnetic field with a very thin extrusion
  • Kapton Voice Coil Former
    Kapton voice coil former is lightweight and efficiently dissipates heat
  • Epoxy Infused Natural Fiber Spider
    Natural fiber spider allows flexibility while the epoxy gives strength during the manufacturing process
  • Passive Butterworth Crossover
    Passive Butterworth Crossover provides smooth transition of frequencies from midrange/midbass to the tweeter element
  • Ferrite Magnet
    Ferrite magnets create a strong magnetic field while remaining small enough to fit nearly every installation
  • Grills
    Grills protect the speaker from accidental damage. Not used if speaker is mounted behind vehicle pane
  • Tweeter Mounting Hardware
    Several mounting options are included to maximize installation placement
  • Warranty
    Includes 2 year manufacturer's limited warranty
  • In the box
    2 x RTI 30 tweeters, 2 x DWA 160 midrange/bass drivers, 2 x DXA 216 crossovers, operating instructions and complete installation material including templates


  • Aluminum Dome Tweeter with Aluminum Voice Coil
    Aluminum delivers a smooth high frequency sound while handling plenty of power
  • Phase Lens 
    The MB Quart phase lens was develop over a decade for WideSphere™ technology tweeters to dramatically enhance the sound state for off-axis listening
  • Treated Silk Surround
    Silk reduces harsh distortions which can develop on the the surround in the transition point from the tweeter dome to frame where the surround mounts
  • Mica Filled Poly Cone
    Deep bass tones with musical midrange frequencies
  • Tinsel Leads Silicone Jacket
    Silicone jacketed, extra flexible leads for strength and durability
  • Voice Coils
    20mm (.75”) voice coil on a 26mm (1”) dome - creating a larger radiating area on the dome creates more output giving the tweeter a louder yet smoother sound
  • Voice Coil Former
    Lightweight aluminum former which helps voice coil dissipate heat
  • Bumped Design Cotton Spider
    Adhesive impregnated cotton spider with bumped design which allows for more clearance and longer excursion
  • Crossover Design
    Improved separation between tweeter and mid/woofer with 12dB per octave crossover network
  • Proprietary Heavy Gauge Powder Coated Stamped Steel Basket
    Provides rigged support for speaker even at high power especially important when not using a subwoofer, due to low bass frequencies
  • Mounting / Installation
    Euro-DIN - Unique shaped mounting brackets and holes to accommodate OEM and custom installations for midrange
  • Spade Push On
    Connectors are designed for crimp connectors allowing for quick disconnect or direct wire solder connections for permanent installations
