MAIN FEATURES
The KICKER ST 9" (229mm) Street Series Square Mid-Range Speakers are designed for extreme output, powerful vocals and competition-level SPL applications. Featuring PA-style woofers and KICKER's square cone design, these speakers provide nearly 20% more output than comparable round designs, making them ideal for high-output systems.
The square pressed-pulp cone and treated cloth surround are engineered for high-power performance and efficiency, while the wide 80Hz–5.5kHz frequency response helps deliver strong midrange reproduction and clear vocals. The ST9MR4 is specifically voiced to keep vocals prominent even when paired with powerful bass systems.
Spring-loaded terminals accept up to 12 AWG speaker wire for secure connections, while the 4-ohm impedance and recommended 50–300W RMS amplifier power provide flexible system configuration. Supplied as a pair, these speakers are built for serious street and SPL audio systems.
