Compact and optimized for surface mounting, the GRS 5SMP-8 is a 5-1/4" poly cone woofer designed for clarity and control in midbass performance. Engineered with thoughtful design features like a copper cap and aluminum voice coil former, this driver offers solid performance for DIY speaker projects and compact audio systems.
Highlights of the GRS 5SMP-8
- Damped poly cone with rubber surround ensures smooth, low-resonance response
- Aluminum voice coil former enhances thermal stability and power handling
- Copper cap reduces inductance and minimizes distortion
- Low-profile frame with integrated foam gasket is ideal for surface mount designs

GRS 5SMP-8 Surface Mount Woofer
The GRS 5SMP-8 is a versatile 5-1/4" 8-ohm woofer tailored for surface mount applications, delivering a usable frequency range from 50 Hz to 2,500 Hz. Its poly cone construction and rubber surround help suppress unwanted resonances, while the vented pole piece and aluminum voice coil former support effective thermal management. A copper cap on the motor structure further reduces voice coil inductance, improving high-frequency clarity and lowering harmonic distortion. With an SPL of 86.4 dB at 2.83V/1m and an RMS power handling of 35 watts, the 5SMP-8 is well-suited for compact full-range systems, line arrays, or midbass augmentation in 2-way speaker designs. Its integrated foam gasket also helps achieve a tight acoustic seal during cabinet mounting.
