The MTX RFL4001D mono block amplifier is a monster of power. It is at the cutting edge of technology and performance. This is the standard of the brand's amps. With more than 4000W RMS in class-D (very high efficiency), it pushes the limits of amplification connected to a 12V battery. To achieve this, we spent three years at his bedside to bring together what was best for him. We worked on the power to be important, always available, to arrive quickly (super fast rise time) and to make it stick perfectly to our RFL12 and RFL15 subwoofers - They are made to work together.
We have spent more than a year making its operation reliable. We also gave it the best components available. The power supply is cut by the most efficient MOSFETs available from the best manufacturer, International Rectifier (USA). They support 640A each, 175 ° C and there are 12 of them !!! We used 6 transformers to distribute the load and the temperature. These are quality transformers and they are particularly efficient (so they heat less).
The energy storage at the power supply output is provided by 23 capacitors (!!!) of the Elna (DE) brand with low resistance, so ultra fast. They withstand 105 ° C, but never exceed 60 ° C even after 5 days at full strength (This is our reliability test ...). On the power stage, we used MOSFETs from International Rectifier which support 280A each ... We clearly spent lavishly.
To verify the correct operating balance of the RFL4001D, we monitored it with a thermal racing camera over $ 35,000. It allowed us to monitor the temperature of each component and the width / thickness of each track on the PCB. It's been a painful job, but suddenly the MTX RFL4001D performs much better than our wildest expectations ... which are very high, of course.
The RFL4001D is the highest performing amp ever built by MTX. In short, you've never heard anything like it. Boom...
