Cerwin Vega Mobile 8" Ultra High Efficient Midrange Driver

Introduction

Congratulations on purchasing Cerwin Vega Mobile speakers for your car audio system. You have chosen Cerwin Vega Mobile because you deserve the best!

Cerwin Vega Mobile speakers were designed and engineered to reproduce great sound quality for many years of listening enjoyment in your vehicle!

It is highly recommended that your new speakers be installed by an authorized Cerwin Vega Mobile dealer. Your authorized dealer can professionally assemble/disassemble the interior of your vehicle and set the proper speaker placement for ideal sound quality.

If you decide to install the speakers yourself, please thoroughly read through this manual before getting started. This manual will help familiarize yourself with these speakers and guide you through the installation process and procedures.

Installation

Installing the Speakers

Your new Cerwin Vega Mobile series speakers were designed with the flexibility to be installed in multiple locations. However, to ensure the best performance possible, it is important to isolate the front sound waves of the speaker from its rear sound waves. This is done by securely mounting the speaker to a flat surface known as a baffle. Make sure to seal the speaker to ensure there are no air leaks around its frame.

Diagram Description: A diagram shows a speaker assembly. The main speaker unit is depicted from the front, featuring mounting holes around its perimeter. A separate mounting baffle or adapter plate is also shown from the front, with corresponding holes. Screws are illustrated connecting the speaker to the baffle, emphasizing secure mounting to a flat surface to prevent air leaks.

Selecting a Location

If your vehicle has existing factory locations, the easiest method would be to replace them with the exact same size speaker. In the case where there is not a factory speaker location, there are many places where the speakers will fit in a vehicle, but they are not always the best locations for good sound. Make sure to take the time to select the best locations possible.

Mounting the speakers so that they are equal distance from your ears will achieve the best results. If you experience any difficulties, please consult with your local authorized Cerwin Vega Mobile dealer. They have the tools and know-how to help.

Door Mounting (if not using factory locations)

Prior to cutting, remove the panel from the door and check for clearance in the intended installation area, making sure the window will go all the way up and down without any interference. Avoid cutting any structural metal support or braces to mount the speakers.

Rear Deck Mounting

There are two primary methods for mounting speakers in the rear deck of a vehicle: top and bottom mounting. Top mounting requires dropping the speakers in through the deck (interior) while bottom mounting secures the speakers from underneath (trunk). Either method requires a good seal around the frame for the best performance.

Running New Wiring

In most cases when mounting new speakers, you will use the factory supplied wiring, but if new wires have to be run, there are some precautions that need to be taken. If the wire needs to run through metal, such as a door jamb, always use a grommet to prevent damage to your wires. Never run wire through bare metal! This can damage the source unit, amp, or even the speakers themselves. Safety of the wiring against short circuits is the most important installation concern.

Features

The Cerwin Vega Mobile 8" Midrange Driver incorporates several advanced technologies:

• 1. 02-Cast Technology: This technology finely tunes the aluminum die-cast baskets' microstructure. Oxides formed in the mold virtually eliminate gas porosity, cracks, and segregation. This process increases basket strength while lowering basket resonance, contributing to more defined and accurate acoustics.
  Diagram Callout: Refers to the die-cast aluminum basket structure.
• 2. LRS - Linear Rolled Spider: A symmetrical over-under weave design and hybrid material blend provide exceptional strength and reliability. LRS ensures music sounds good at all volume settings and remains controlled and dynamic even at peak volume levels.
  Diagram Callout: Refers to the spider, a suspension component.
• 3. CCD - Curvilinear Cone Design: Curvilinear shaped cones improve off-axis performance through their unique geometry. The sensitive inner-section features a severe angle design, while the outer edge is flat and more rigid, reproducing louder mid-bass frequencies uniformly throughout the listening environment.
  Diagram Callout: Refers to the speaker cone.
• 4. EMAR - Cone Design (Exponential Multi Annular Rib): By exponentially increasing cone thickness and adding annular ribs to the outer edge, this design stiffens the cone to decrease resonance in the upper frequency bandwidth. Complex vibrations are greatly reduced at high volume levels, resulting in more mid-bass.
  Diagram Callout: Refers to the cone structure with annular ribs.
• 5. HCC - Hybrid Cone Construction: This technology combines three types of unique fibers (Kapok, Block Spruce, and Unbleached Kraft) felted together under a specialized polypropylene coating. Unique traits like tubular shaping, superior rigidity, and lightness ensure this strong, ultra-stiff hybrid cone emits a natural sound without sacrificing efficiency.
  Diagram Callout: Refers to the internal fiber construction of the cone.
• 6. TCRS - Treated Cloth Ribbon Surround: Created through a 50-year-old process of weaving pure cotton in a plain weave mesh pattern, then saturated and sealed with phenolic and other compounds. A multi-ribbed design achieves a desired resonant frequency perfect for reproducing extremely loud mid-bass.
  Diagram Callout: Refers to the speaker surround.
• 7. HGM - High Grade Magnet: High-grade (Y35), high-energy magnets provide high resistance to demagnetization and are over 20% stronger per ounce than lower-grade magnets. This results in extraordinary efficiency and loud, controlled sound.
  Diagram Callout: Refers to the magnet assembly.
• 8. FAY - Forged Alloy Yoke: A one-piece cold-forged 1008 alloy steel yoke initiates better magnetic transfer. Combined with reduced carbon content, this feature allows for the greatest and strongest retention of magnetic fields.
  Diagram Callout: Refers to the yoke, part of the magnetic circuit.
• 9. CCAC - Copper Clad Aluminum Coil: Copper-clad aluminum wire voice coils are lightweight and offer excellent heat dissipation. Copper is coated over an aluminum surface, providing equal copper surface area at a fraction of the weight of solid copper wire. CCACs provide maximum sensitivity and extend high-frequency response.
  Diagram Callout: Refers to the voice coil.
• 10. RAF - Rolled Aluminum Former: Rolled aluminum voice coil formers are known for superior thermal capabilities. Their low mass and thermal transfer characteristics make them ideal for maintaining exceptional dynamic response and preventing voice coil damage.
  Diagram Callout: Refers to the former supporting the voice coil.
• 11. SWL - Symmetrical Woven Leads: Symmetrical woven, ultra-flexible braided tinsel leads move signal from the speaker terminals to the voice coil. They prevent kinetic failures and shorting. Placement 180° apart provides even resistance on the voice coil/cone assembly, reducing voice coil gap and preventing rub.
  Diagram Callout: Refers to the tinsel leads connecting terminals to the voice coil.
• 12. PPT - Pushpin Terminals: High-quality nickel-plated, high-tension spring-loaded terminals offer an oxide-free, low-resistance connection. Power from amplifiers travels efficiently to the voice coil, even under severe conditions.
  Diagram Callout: Refers to the speaker terminals.

Technical Data Table:

SPL vs Freq Graph Description: This graph plots Sound Pressure Level (SPL) in decibels (dB) on the vertical axis against Frequency in Hertz (Hz) on the horizontal axis. It illustrates the speaker's output level across different frequencies. The curve shows a relatively flat response from approximately 100 Hz up to 5 kHz, indicating consistent volume output in this range, with some variation at the extremes.

Impedance vs Freq Graph Description: This graph plots Electrical Impedance in Ohms (Ω) on the vertical axis against Frequency in Hertz (Hz) on the horizontal axis. It shows how the speaker's resistance to electrical current changes with frequency. A prominent peak occurs around 80 Hz, representing the speaker's resonant frequency, after which impedance rises with increasing frequency.
