MB Quart PK1-113 Premium 5.25 inch 2-way coaxial speakers featuring 1 inch Magnesium WideSphere™ Technology Tweeters with pop aerated paper cone with a Mica blend.

General Features:

• Tweeters    
  1" magnesium dome tweeter for exceptional musical reproduction of high frequenices are the heart of the system. The innovative tweeter design develops an off-axis dispersion pattern that creates a larger sound stage which brings a concert in your car to life.
• Cone Material    
  Lightweight aerated pop paper cone with Mica blend for strength and superior bass frequency reproduction. This design adds strength and superior bass frequency reproduction. This means that midrange and bass frequencies remain very musical without the distortions that can be caused by the cone flexing. With the curvilinear design the geometry is specifically engineered for best upper band midrange response which is critical for frequencies that are responsible for vocals and acoustic instruments like piano, guitar and percussion.
• Surround / Cone Coupling    
  High temperature adhesives are utilized to keep the coupling from cone to surround fused. Adhesives are also impervious to cold weather.
• Gasket    
  Molded Polymer Sealing gaskets are utilized to keep the speaker isolated from the mounting surface and improve protection from water and dust intrusion.
• Voice Coil / Former Assembly    
  High temperature imported wire on Kapton former. The former is lighter than a standard speaker which allows the component to support slightly higher frequency extension and efficiency.
• Spider    
  Red woven fiber cotton poly blend spider to stabilize the cone and voice coil in all musical situations.
• Cooling System    
  Venting allows air passage through the spider and speaker frame ribs to exchange air over the voice coil.
• Crossover    
  Premium coax (2-way) designs feature a built-in audiophile crossover which guides the frequencies from the amplifier to each driver (speaker). This system is designed with tight tolerance components for superb sound quality.
• Tweeter Hardware    
  Tunable waveguide tweeter housing with removable phase lens creates larger than life sound stage.
• Frame    
  Aerospace grade PA66 composite with 30% glass fiber speaker frame to assure that no harmonic distortions affect the tone of the speaker.
• Connectors    
  Stainless steel, push and insert connectors resist corrosion and create a superior electrical connection.
• Grills    
  Included
