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.

Highlights

  • 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

Product Details

Peerless by Tymphany STW-350F-188PR01-04 15 High Power Subwoofer

A New Generation of High Output, High Power Subwoofers

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.

Massive 7.4 Diameter x 2.25 Long Voice Coil

With small enclosure subwoofer design high-moving mass is necessary, but it is difficult to apply mass where it can be put to work. For the STW-350F, it was put into the voice coil − this improves the performance of the driver by raising the motor force. Unlike a conventional motor design, Bl changes very slowly as function of voice coil displacement. A voice coil with large surface area also offers another benefit − power compression is practically non-existent. Because of this, the voice coil takes longer to heat up, resulting in uncompressed dynamic musical peaks.

Internal Motor Design

To drive a high moving mass a subwoofer needs a powerful motor. In most cases a more powerful motor is achieved with a larger magnet (which increases a driver cost, size, and weight) or using a more efficient neodymium magnet (which is unstable and loses strength as the temperature increases). An additional benefit of the STW-350F's giant coil is that Peerless was able to mount a ferrite motor inside of the voice coil. Conventional motor structures with the magnet outside of the motor lose 50% of their energy in stray fields, while a magnet on the inside of the voice coil will have 90% or better magnet utilization. The STW-350's motor is the best of both worlds: reliable and efficient.

Long Coil + Long Gap = High Excursion

With an Xmax of 10.4 mm this driver might not seem all that impressive. However, Xmax is just a physical measurement and not actually the limit of linear excursion (Xmax = (Voice Coil Length - Magnetic Gap Height) / 2). The STW-350F has a remarkably long 36 mm magnetic gap with a 57 mm long voice coil. Thanks to such extreme dimensions and a well controlled magnetic field, this driver is capable of 45.5 mm of excursion before any major loss in motor strength (Bl). In other words, this driver is capable of 90 mm (3.5) peak to peak excursion while still producing low distortion output.

Front and Rear Mounting Points

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.

In 1926, in Danemarca, sanctuarul producatorilor de echipament audio higth-end, avea sa apara inegalabila Peerless

Inca de atunci Peerless a furnizat solutii audio de cea mai buna calitate, produsele lor devenind rapid un etalon in industria de referinta.

In anii 2000, Vifa, o companie infiintata in 1933 de un mecanic de masini si botezata chiar de fondatorul sau "fabrica de difuzoare a lui Videbæk", a fuzionat cu Peerless pentru a forma Danish Sound Technology (DST). 

5 ani mai tarziu, Tymphany, o tanara companie infiintata in 2014, a cumparat DST împreună cu marcile originale Peerless, Vifa și Scan-Speak.

Ulterior Tyfphany a abandonat productia de difuzoare Vifa aproape in totalitate sau le-a vandut sub numele de Peerless V-Line.

Incepand cu anul 2005, tehnologia difuzorelor Peerless a fost o constanta care a dus pe cele mai inalte culmi industria muzicala si acustica sub numele Peerless by Tymphany.

Difuzoarele Peerless sunt astazi cele mai performante din acest segment de piata si furnizeaza un sunet premium pentru orice aplicatie, aducand un nivel consistent de calitate tuturor produselor finale, innobilandu-le cu tehnologia si designul lor.

Seria Platinum ofera solutii de ultima generatie cu noile difuzoare din gama inovatoare NE,  impreuna cu wooferele Tymphany XLS și XXLS si subwooferele Peerless by Tymphany.  

Difuzoarele SDS si HDS cuprinse in seriile Peerless V-Line by Tymphany Gold, ofera performanta suplimentara la preturi rezonabile

Tehnologia inegalabila a difuzoarelor daneze si productia eficienta in China, unde standardele de productie sunt unice, aduce compania Timphany pe culmile gloriei, dandu-i posibilitatea de a oferi produse premium la preturi foarte bune pentru industria OEM si amatorii de proiecte DYI.

Astazi Tymphany proiecteaza si fabrica unele dintre cele mai inovatoare sisteme de difuzoare si sisteme audio de pe piata. Cu peste 3.000 de angajati, compania are vanzati uriase la nivel mondial, produsele lor fiind utilizate de cei mai cunoscuti producatori de aparatura hi-fi. 

Proiectate de ingineri talentati, difuzoarele Peerless by Tymphany sunt cele mai fiabile de pe piata, cu componente de calitate care sunt testate la standarde riguroase de performanta. Acest lucru face ca produsele sa redea un sunet impecabil indiferent de produsul final din care fac parte. 

Peerless by Tymphany continua sa exploreze noi domenii cum ar fi difuzoarele cu tehnologie avansata de amplificare, subwoofere high-end, woofere de compresie și tehnologii de difuzoare plane, ca parte a procesului continuu de dezvoltare, pentru a oferi clientilor cea mai variata gama de produse.
