RFL4001D

Flagship terrorizing power 4000W RMS @1Ω Class-D mono block with complete active x-over and bridge mode

Introduction

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...

Restrictions

The power of the amplifier must not exceed that of the loudspeaker. We must compare RMS powers with RMS powers. The amplifiers should not be exposed to moisture, excessive vibration, or high temperatures.

Warning

MTX wants you to enjoy your hearing for a long time. Excessive exposure to loud volumes can damage your hearing. The United States Department of Labor recommends not exceeding the following recommendations:
90db : maximum 8 hours / day
92dB : maximum 6 hours / day
95db : maximum 4 hours / day
97db : maximum 3 hours / day
100db : maximum 2 hours / day
102db : maximum 90 minutes / day
105db : maximum 60 minutes / day
110db : maximum 30 minutes / day
115db : maximum less than 15 minutes / day
120db : immediate danger, 0 minutes / day

It's a crazy thing ... I already had an X3000D, but there it grows at least twice as much ... I have this amplifier with an RFL12, it's just happiness ... and it takes no room compared to my four square subwoofers from before.

Jean Taiti Scholermann

At the top of these amps… High-end finish and solid construction. It is really very powerful. Attention, you need the subwoofers that are able to follow (RFL)

SAXSound

Ohhh la la…. Be careful, it's power… Never seen such power. every serious blow is scary with this amp. It plays really hard, and it's solid to death! MTX is the best ...
