CLEARANCE Tectonic TEBM36S12-4A 1-1/2" Square BMR Full-Range Speaker 4 Ohm

Tectonic
Part #297-2170  
Model: TEBM36S12-4/A
The The TEBM36S12-4/A Balanced-Mode Radiator (BMR) is a driver with an extended frequency response and wide directivity compared with a conventional driver. It combines the benefits of Tectonic bending-wave technology and pistonic modes of operation. It is ideally suited for compact audio applications that require a full-range, high performance acoustic solution including; boom boxes, smart speakers, computer speakers, and bookshelf speakers.
Key Features
  • Wide sound dispersion delivers room filling sound
  • Ultra compact design minimizes visual impact -- only 2.56" square x 1.17" deep
  • Drive unit design simplifies integration into a product
  • Improved smooth frequency response and extended bandwidth

Overview

Tectonic TEBM36S12-4A 1-1/2" Square BMR Full-Range Speaker 4 Ohm

The TEBM36S12-4/A Balanced-Mode Radiator (BMR) is a driver with an extended frequency response and wide directivity compared with a conventional driver. It combines the benefits of Tectonic bending-wave technology and pistonic modes of operation. It is ideally suited for compact audio applications that require a full-range, high performance acoustic solution.

This second generation drive unit has the same audio characteristics as its predecessor, with improved response smoothness and linearity at high excursion.
