The 4" GRS 4SMP-8 is designed to deliver consistent performance making it a perfect fit for compact speaker builds or retrofitting aging systems. Its damped poly cone ensures a natural tonal character, while the rubber surround maintains control over cone excursion for smooth, extended low-frequency response. The woofer’s construction prioritizes longevity and acoustic accuracy, making it a practical choice for both DIY speaker projects and commercial applications.
A key highlight of this woofer is its advanced motor system. A copper cap reduces inductance, helping to smooth high-frequency roll-off and reduce harmonic distortion, while a vented pole piece allows increased airflow across the voice coil to keep temperatures down. Combined with an aluminum voice coil former, these features work together to minimize power compression, ensuring consistent performance even at higher output levels.
Engineered with installation flexibility in mind, the low-profile surface-mount frame makes it easy to install the 4SMP-8 and give your speakers a professional look. The light-weight 2-layer voice coil increases efficiency and improved the high frequency response. Whether you're designing a compact 2-way speaker or restoring a classic system, this woofer offers excellent value and performance.
