Very High Output MB Ferrite Driver 8 Ohm
  • 103 dB SPL 1W / 1m average sensitivity
  • 75 mm (3 in) Interleaved Sandwich Voice coil (ISV)
  • 400 W AES power handling
  • Excellent transient response
  • Additional cone damping treatment
  • Improved heat dissipation via unique basket design
  • Suitable for compact two way, multiway and horn loaded midbass applications

The 15MB700 very high output mid-bass transducer shows exceptional efficiency and is primarily intended for 2-way very compact reflex systems (75 lt.), 3-way systems and horn loaded applications. It combines high sensitivity (103 dB 1W/1m) with a high power handling capability.
The smooth textured curvilinear paper cone, in conjunction with the viscose dampened multiroll suspension, provides excellent cone dampening and excursion control.
The 75 mm diameter aluminum voice coil features the same technology fitted to our top-of-the-range 4” voice-coil models. It employs Interleaved Sandwich Voice coil (ISV) technology, in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard. The low coil inductance results in an improved transient response.
Excellent heat dissipation has been achieved by incorporating air channels into the basket design, between the basket and the top plate. Maximum flux concentration and force factor in the gap are assured by the unique shape and design of the top and back plates which have been designed using our in-house Magnetic Flux FEA CAD resource.
Due to the increasing use of audio systems at outdoor events, the ability to perform in adverse weather conditions or in high-humidity areas is a key feature of the 15MB700. This has been achieved using exclusive cone and magnetic plate treatment processes which allows the speaker to resist corrosion and render the cone water repellent.
