Power Handling: You'll typically see very high "Max Power" or "Peak Power" ratings 10250W, . It's crucial to look for the RMS (Root Mean Square) power rating, which is the continuous power the subwoofer can handle. For a 10-inch Spectrum, this might range from around 800 RMS
Voice Coils: Most Starsound Spectrum 10" subs are Dual Voice Coil (DVC), commonly 4-ohm per coil (D4). This allows for flexible wiring options (e.g., wiring to 2 ohms or 8 ohms) to optimize for your amplifier's impedance
Cone Material: Often features a non-pressed paper cone, sometimes reinforced with glass fiber, paired with a specially treated foam or reinforced ribbed surround for durability and excursion.
Basket: Commonly utilizes an aluminum die-cast basket or a black steel basket for rigidity.
SPL (Sensitivity): Generally has a decent sensitivity rating (e.g., around 90-93dB at 1W/1M), indicating it can produce good sound levels with less power compared to less efficient subs.
Design Focus: Designed to produce loud and impactful bass, fitting the SPL-oriented preference of many car audio enthusiasts in South Africa
