Peerless STW-350F-188PR01-04 15" Dual Voice Coil Subwoofer + SpeakerPower SP1-700 Amplifier Bundle

10% Discount!

The STW 15” subwoofer built for high-performance hi-fi applications and previously previewed at trade-shows is now available! Featuring an 8” voice coil, triple suspension, and a dual-spider design, this driver provides superior low-frequency performance in a smaller-than-traditional enclosure. 

The result of two years of research and development, the Peerless by Tymphany's STW line of subwoofers was designed with performance and space in mind. These drivers offer deep and clean low-frequency reproduction with minimal distortion at high sound pressure levels. Unlike most subwoofers, the STW family of drivers can be mounted in a much smaller box than most traditional 12”, 15,” and even many 10” subwoofers, which is enabled by the high moving mass and 8” voice coil. Each subwoofer also features an FEA-optimized ferrite motor with 90mm peak to peak excursion, and a 188mm voice coil, which provides extraordinarily low power compression. 

Built for high-quality performance and reliability, the STW-350 offers extremely low distortion at 90mm peak-to-peak displacement, which is enabled by the large voice coil and high moving mass. It is also designed with 70L equivalent volume and Fs below 25Hz.

“Using a large voice coil has more than one benefit,” explains George Bullimore, Director of Tymphany's UK Design Center. “The ferrite magnet is designed into the voice coil, which enables more efficient use of the magnet material. Additionally, the large surface area of the voice coil results in practically non-existent power compression.” 

The driver features an FEA optimized ferrite motor with 90mm peak to peak excursion, and a 188mm dual voice coil design, providing extraordinarily low power compression.  It is also designed with 70L equivalent volume and Fs below 25Hz. These features allow the driver to be mounted in a much smaller box than most traditional 12”, 15” and even many 10” subwoofers. The STW 15” subwoofer offers deep & clean low-frequency reproduction with minimal distortion at high sound pressure levels.  Designed for more, the driver is built for high-quality performance and reliability.

• 188mm dual voice coil with extraordinary low power compression
• Long gap, long coil winding design provides +/-20mm linear excursion when voice coil moves up and down
• 90mm peak to peak excursion meets extreme dynamic sound demand
• Resonant Frequency≈ 24 Hz
• 188mm voice coil 
• Paper cone
• Ferrite motor
• Cast aluminum basket
• 4 ohm (with coils in parallel)

Note for the Xmax: The driver is a long gap (36mm) and long coil(58mm) design. This is a benefit for a subwoofer with long excursion (40mm).

Why use SpeakerPower?

There are many unique benefits to working with SpeakerPower:
  • Designed, assembled and tested in Santa Ana California. The 2400W-6000W amplifiers are made entirely with local vendors and qualify for MADE IN USA.
  • Lead times are short. Amplifiers are built to order as you need them. Quantity commitments are small.
  • Custom faceplates, silkscreens and other features are easily accommodated.
  • Some models have UL/CSA approval as a standalone product. This means you don't have to pay for an expensive UL investigation, quarterly inspections of your manufacturing, calibration of test equipment etc etc. The combination cUL mark is already screened on the faceplate.
  • SpeakerPower has over 30 years experience designing and manufacturing loudspeakers and amplifiers for some of the biggest names in the business.
So while piecing together your own amp may appear to be less expensive, when you consider the total cost of time to market, UL/CSA, inventory, engineering etc you will find the SpeakerPower turnkey solution to be very competitive.
