The Peerless STW-350F-188PR01-04 15″ subwoofer produces deep and clean low-frequency reproduction with minimal distortion at high output levels. Designed from the ground up for output, performance, and reliability from the smallest enclosures, this driver with its 7.4″ voice coil, internal magnet assembly, and outrageous excursion capability is a welcome departure from conventional subwoofer designs.
Massive 7.4″ voice coil produces extraordinary low power compression
2 Large aluminum shorting rings for better control and minimal harmonic distortion
Dual 8 ohm voice coil allow multiple wiring configurations including dual amplifier designs
Internal magnet structure provides more force from a smaller magnet
Lower Vas and Fs with higher BL for unmatched low end capability from the smallest enclosures
Extensive voice coil venting for quiet operation and increased power handling
Over 90mm of mechanical excursion prevents failure under the most demanding conditions
The STW-350F-188PR01-04 subwoofer from Peerless was designed with performance and space in mind. This drivers offer deep and clean low-frequency reproduction with minimal distortion at high sound pressure levels. Unlike most subwoofers, the STW-350 can be mounted in a much smaller box than traditional subwoofers, which is enabled by the low Vas, high moving mass, and huge 7.4″ (188 mm) voice coil. This driver also features a unique FEA-optimized ferrite motor, extremely robust suspension, and an incredible amount of venting which provides extraordinarily low power compression even when driven with over 3,500 watts of power. This driver is built for high-quality performance and long term reliability.
Note: Due to the incredible amount of venting on this driver, when used outside of an enclosure, the air turbulance generated will create audible noise. Because of this, we recommend the use of a sealed enclosure.
Combining celebrated Danish transducer engineering with the manufacturing efficiencies enabled by Asian manufacturing, Tymphany propels Scandinavian speaker technology into the 21st Century. By paying tribute to iconic classic designs from Vifa and Peerless, and complementing them with bold new pro and consumer loudspeakers entries, Tymphany is positioned for further decades of audio excellence.
Due to the weight and extreme force that the STW-350F is capable of, Tymphany included rear mounting points on the back side of the frame. By attaching the rear of the frame to a brace in an enclosure, the baffle will be solidly tied to the sides walls increasing the rigidity of the enclosure while helping to support the overall weight of the STW-350F. These threaded holes accept M6 x 30 screws.
