Introducing the Sub E3 KSR-228

The Sub E3 KSR-228 is a dual subwoofer system utilizing two 18-inch bass drivers combined with a 5-inch voice coil, delivering extremely powerful and energetic bass reproduction. The dual-bass configuration allows the speaker to generate greater sound pressure and increase bass coverage in larger spaces.

The speaker boasts a real power output of up to 2400W RMS and a peak power of 9600W, enabling powerful and stable operation at high intensity for extended periods. This power level is ideal for professional stage systems or commercial karaoke businesses requiring loud sound and high performance.

Technical parameters of the product to consider:

• Frequency response range: 30Hz – 250Hz: The low frequency range of 30Hz allows the speaker to effectively reproduce EDM, remix, dance, or live music genres with thicker and more energetic bass. At the same time, the frequency range up to 250Hz enables seamless pairing with full-range or line array speakers above.
• Sensitivity: 104dB (1W/1m): High sensitivity allows speakers to produce higher volume levels with the same input power. This makes the system more efficient, while also supporting more powerful and expansive bass in large spaces or crowded environments.
• Nominal impedance: 4Ω: A 4-ohm impedance allows the speaker to draw more power from a professional power amplifier. However, for stable system operation and maximum efficiency, users should choose a power amplifier that matches this impedance level.
• RMS power: 2400W: This is a very high actual power output, indicating that the E3 KSR-228 is designed for professional sound systems requiring high performance. The speaker can operate stably for extended periods at high volume while maintaining strong bass and solid sound.
• Peak Power: 9600W: With a maximum power output of up to 9600W, the speaker can handle powerful climaxes or sudden, strong bass signals without losing power. This results in a more explosive and energetic sound in large entertainment spaces or stages.
• Speaker configuration: 2 x 18-inch bass driver, 5-inch voice coil: Two drivers working simultaneously produce a thicker, deeper, and more powerful bass than typical 18-inch single subwoofers. The 5-inch voice coil also helps the speaker handle higher loads and improves heat dissipation during continuous high-intensity operation.
• Connect Speakon +1/-1: The speaker uses professional Speakon connectors, ensuring stable signal transmission and greater safety during use. This is a common connection standard in high-power stage and event sound systems today.
