Tectonic TEBM46C20N-4B BMR Full-Range Speaker

The TEBM46C20N-4B 3" full-range from Tectonic offers extremely flat response from 200 to 20,000 Hz. It is an ideal driver for compact audio applications that require a full-range, high performance acoustic solution.

 

Highlights

  • Bending-wave technology and pistonic modes of operation improve high frequency response
  • Flat diaphragm increases dispersion for better off axis response
  • Less than 1.375" deep for mounting in extremely shallow locations
  • 67" across for close center-to-center spacing in line arrays

 

Product Details

Tectonic TEBM46C20N-4B BMR 3" Full-Range Speaker 4 Ohm

 

The Tectonic TEBM46C20N-4B 3" full-range speaker achieves the maximum amount of quality sound from small enclosure sizes. Aside from the benefits to acoustic engineers, the BMR's compact, square form factor also appeals to designers. BMR drive units can be a cosmetic feature of a product, or be integrated discreetly into designs—and potentially even hidden from view altogether. The technology's wide directivity enables flexible placement options, while the wide frequency response means BMR drivers can also deliver cost savings to engineers, since no crossover components or frequency-specific drivers are required. The TEBM46C20N-4B 3" drive unit has an extended frequency response with wide directivity and is ideally suited to compact full-range applications that require a high-performance acoustic solution. Typical application examples include mp3 players, docking stations, and Internet/DAB (Digital Audio Broadcasting) radios, and homeheater speaker bars.
