        Beyma 12BR70 Low Frequency Transducer

         

        The Beyma 12BR70 is a versatile 12-inch woofer optimized for low-frequency reproduction in compact enclosures. Designed to handle 125 W AES and 250 W program power, it features a 2” copper voice coil and ferrite magnet structure that provides a balanced performance in budget-sensitive applications. Operating from 35 Hz to 4,000 Hz, this transducer excels in bass and sub-bass duties with a sensitivity of 93 dB (1W/1m). The unit’s Xmax of ±8 mm and 26 mm peak-to-peak excursion enable it to reproduce low frequencies cleanly and with minimal distortion, making it well-suited for small PA cabinets and hi-fi subwoofer systems. With a low resonant frequency of 31 Hz and high mechanical compliance (345 µm/N), the 12BR70 performs efficiently in enclosures ranging from 50 to 120 liters. Its compact 134 mm depth and lightweight 3.6 kg build ensure easy integration into portable systems, making it a reliable choice for DIYers, audio hobbyists, and small venue applications.
