Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Anthem MRX 1140 8K is rated at 140 watts RMS into 8-ohms (2 channels driven).
Here are the main highlights of its performance specs:
- 140 watts into 8-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)

Which speakers suit the Anthem MRX 1140 8K?
140 W into 8 ohms, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current

Need more power?
Anthem MRX 1140 8K is rated at 140 watts into 8 ohms, which puts it in our 121 to 180 watts band. The next band up is Over 180 watts, which is worth about 2.3dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the 91 to 120 watts band and better speakers.
When pairing the Anthem MRX 1140 8K with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
