Alphasonik NS683 6x8/5x7 3-Way Car Speakers - Clear Sound, Big Value

In this review the Alphasonik NS683 3-way speakers are evaluated for drivers who want an affordable upgrade that still delivers clear highs and usable bass. The bottom line: these speakers are best for budget-conscious car audio enthusiasts who want a noticeable step up from factory speakers without adding a separate subwoofer. The combination of a PEI dome tweeter, polypropylene cone and a built-in crossover produces a balanced sound that handles vocals and mid-bass well, making the NS683 a practical choice for daily listening and moderate-volume driving.

Key Features

• 3-Way Full-Range Design: The tri-element design separates frequencies so vocals and instruments remain distinct even at higher volumes.
• PEI Dome Tweeter: The dome tweeter provides clearer high frequencies and improved detail compared with typical paper tweeters.
• Polypropylene Cone with Rubber Surround: The cone and surround combination offers durability and controlled mid-bass response for consistent performance.
• Built-in Crossover: The included crossover helps each driver focus on the frequencies it handles best, improving overall clarity and imaging.
• Complete Installation Kit: The package includes speaker wires, screws and speed clips to simplify installation into compatible doors or rear decks.
• Compact Mounting Depth: With a 2.6 in mounting depth the NS683 fits many common factory locations where deeper speakers would not.

Who It's For

The NS683 is aimed at drivers replacing worn factory speakers or upgrading a head unit-level system who want better definition without adding an amplifier or separate subwoofer. It suits commuters and weekend drivers who listen to vocal-forward music or rock where midrange clarity and punch matter most.

Those seeking deep, room-filling bass or audiophile-grade resolution at very high volumes should look elsewhere; if you need extreme low-end output, a dedicated powered subwoofer or larger component system will serve better than these full-range 3-way speakers.

Pros & Cons

Frequently Asked Questions

Do these speakers include wiring and mounting hardware?
Yes, the package ships with speaker wires, screws, speed clips and an operations manual for installation.

Will these fit behind factory grilles in most cars?
The speakers have a 2.6 in mounting depth and overall dimensions for 6x8/5x7 applications, so they fit many common factory locations but measuring your vehicle is recommended.

Is an external amplifier required?
No, the speakers can run from a factory head unit, but because they are 3 ohm and can handle higher power, an amplifier will improve headroom and dynamics.
