STW-10 STW-12 specifications

Power Acoustik STW-10 and STW-12 are powerful subwoofers designed for car audio enthusiasts seeking high performance and deep, resonant bass. These models are part of Power Acoustik’s STW series, known for delivering exceptional sound quality and impressive volume levels.

The STW-10 features a 10-inch cone, while the STW-12 comes with a larger 12-inch cone. This size difference allows each subwoofer to cater to various audio preferences and vehicle types. Both models are engineered with a robust cast aluminum frame that ensures durability and strength, allowing them to withstand the rigors of installation in vehicles.

One of the standout features of the STW series is its high power handling capability. The STW-10 can handle peak power of up to 1200 watts and an RMS of 300 watts, while the STW-12 takes it up a notch with a peak power handling of 1500 watts and an RMS of 400 watts. This exceptional power handling ensures that both subwoofers can produce deep bass without distortion, making them ideal for hip-hop, electronic, and other bass-heavy music genres.

The subwoofers utilize a high-temperature voice coil designed to dissipate heat effectively, allowing for extended playtime without overheating. This technology is crucial in maintaining performance over longer listening sessions. The dual 4-ohm voice coil configuration provides flexibility in wiring options, enabling users to achieve desired impedance levels that suit their amplifiers and sound systems.

Additionally, the STW subwoofers feature a treated paper cone that enhances sound clarity and provides a well-defined bass response. Their design prioritizes both aesthetics and acoustics, with a sleek finish that fits well within any car’s interior.

Another notable aspect is their powerful but efficient ferrite magnet, which provides strong magnetic flux for better efficiency and output. Coupled with a sophisticated cooling system, these subwoofers are designed to deliver consistent performance even under heavy use.

In conclusion, the Power Acoustik STW-10 and STW-12 subwoofers offer an excellent combination of power, clarity, and durability. With their high-power handling, efficient cooling systems, and robust construction, they stand out in the market for car audio solutions. Whether for competition or casual listening, these subwoofers are built to impress and elevate the overall audio experience in any vehicle.
