Description
The American Bass Symphony 4" Speakers (Pair) are full-range 4-inch drivers designed to upgrade factory audio systems, delivering rich, crystal-clear mid-to-high detail with a neodymium stationary tweeter for sparkle. Seven sizes available provide installation flexibility across a wide range of vehicles.
- RMS Power: 45W RMS, indicating the continuous power the drivers are designed to handle with a suitable amplifier, for steady, clean listening without distortion.
- Max Power: 90W, the peak power the speaker can tolerate in short bursts before risking distortion or damage.
- Impedance: 4 ohms, affecting how much current the amp must deliver and its compatibility with head units or external amplifiers.
- Sensitivity: 87 dB, showing how efficiently the driver converts power into audible output at a given distance.
- Mounting Depth: 2 in, a shallow profile that helps fit into tight dash or door installations.
- Cutout Size: 3.75 in, the required hole diameter for proper mounting.
- Magnet Size: 6.5 oz, contributing to magnetic control and overall driver performance.
- Voice Coil Size: 25 mm, influencing power handling and thermal management during operation.
- Basket Type: Stamp Steel, providing rigidity and damping for accurate sound reproduction.
- Tweeter Type: Neodymium stationary tweeter, delivering crisp high-frequency detail with efficient performance.
- Cone Material: Black injection cone, combining strength with reduced distortion under excursion.
- Surround Material: Butyl rubber surround, offering durable, stable response and long-term reliability.
- Series: SYMPHONY SERIES, identifying the family and its intended performance characteristics.
- Size Options: Seven sizes available, enabling flexible matching to various vehicle openings and mounting constraints.
In a typical car audio build, these 4" Symphony speakers upgrade factory sound by delivering clear mids and highs with controlled high-frequency energy from the neodymium tweeter, while the robust cone and surround support durable, responsive sound. The 4-ohm impedance and 45W RMS rating align well with stock head units or compact amplifiers, helping you achieve a more articulate, engaging listening experience without overloading the system. Availability in seven sizes makes it easier to fit multiple vehicle applications while preserving sound quality.
