Introducing the all-new 212SE, a powerfully wrought design that brings the attack that only 1,000 watts (1,700 watts peak) twin long-stroke S/5 12″ bass engines, partnered with (2) X 12″ passives can bring to bear.

Double Down

Twin Continuous Cast™ Alloy Bass Engines

To produce their highest output single-box solution, they doubled up on the Continuous CastTM Alloy Bass Engines that bring critical acclaim to Serie S, altering them slightly for this twin front-firing configuration. These twin actives are responsible for 212/SE’s incredible speed and tactility.

Our Continuous CastTM Alloy Cones reduce moving mass while maintaining rigidity, producing far more speed and precision than prior designs. These twin long-stroke 12″ bass engines, partnered with (2) matching 12″ passives provide the speed quality of a REL with a power never felt before. This combination offers the driven surface area of twin 17” drivers in a cabinet just 16” wide.

Command and Control

NextGen3 1,000w Digital Amplifier

Beyond RELs proprietary drivers, the performance of a REL is determined by our unique input filters and amplifiers. 212/SE harnesses a simple filter-type that is very fast—about 8 milliseconds in group delay– to cross out unwanted higher frequencies to our driver. This speed and gentle crossover slopes allow for seamless blending of RELs with the main speakers.

RELs do not include a high pass filter to cross out bass from the main speaker because to do so would generally produce more unwanted effects than the minor benefits such a design confers.212/SE’s power amplifier is a powerful NextGen3 1,000W (1,700 peak) digital amplifier. Their Herculean design allows each driver to output over 110 dB with ease–power enough to drive very large rooms to very high output.
