B2 Audio Rage 850Mi

RAGE MI 

Imagine the RAGE amps, with their features, performance and versatility. Their footprint is small for their performance, but can it be wrapped up in a slight different package? The RAGE MI, where the MI equals Mini does exactly that. Power, Performance, Perception & even smaller! It sounds too good to be true, but with a few redesigns we’ve made it possible.

Offering the exact same power as the RAGE 1200’s wouldn’t make any sence, so we dialled it back a bit. Not much though, the RAGE MI 1000.4 still offers an impressive true 4 x 175 W RMS @ 4 Ω. In dyno testing we were less  than 6 % shy of that at 8 Ω! That goes to say these amps are beyond expectation.
The other RAGE MI offering is a 850 W mono and stable at 1 Ω. The same efficiency is clear here, 2 Ω dyno performace boasts more than 600 W.  The near identical footprint of these 2 amps makes them perfect for sleek installs.

Any Level

The  MI mono took notice of its RAGE 1200 siblings high level feature. The high & low level inputs offers greater flexibility, especially in vehicles where no RCA outputs are present. Given the modest dimensions, the amp can be hid away nearly everywhere (9.5 x 4.9 x 2.2″ / 24 x 12.5 x 5.7 cm).  There’s no excuses for having insufficent bass response anymore. Even with a small amount of space for an enclosure, our shallow mount woofer RIOT FL10 solves that.
The RAGE MI 850 has a fully featured 12 dB / octave crossover section with 10 Hz ~50 Hz adjustable subsonic, 35 Hz ~250 Hz lowpass & a fixed 0 ~12 dB boost level @ 45 Hz. We even managed to squeeze in an external bass level remote port.

Packing the panel

The 4 channels of the RAGE 1000.4 MI takes up the entire panel. We didnt narrow it down with fixed crossover points & only 1 crossover type per stereo channel. The amp has fully configurable high & low pass crossovers on all channels. With the 50 Hz ~5 KHz adjustable frequency range the amp is ideal for anything , midwoofers, midranges, even bullet tweeters! Seeking more? The bridged configuration has more than 500 W available per channel, equalling over 1000 W RMS in total! With lowpass crossovers set accordingly, this tiny amp can used as a pure sub amp, or even as a tri-mode, with loudspeakers on the unbridged channels (front) and a woofer on the bridged channel (rear).
