M 520 F Stereo Set

This speaker is a model full of dynamic energy and enthusiasm. Weighing in at only 35 kilograms, the 1.15 meter high and 0.5 meter deep M 520 F offers immense mass and volume capacity, which is put to optimal use based on precisely and efficiently engineered technology.

Neodym tweeter and monumental bass

The column contains two 2 x 160 mm carbon fibre midbass drivers and a 25 mm neodym tweeter, and is supported by a laterally emitting 300 mm woofer. The result of this configuration is a conveniently thin front end combined with monumental bass reproduction. The integrated woofer functions as a pure subwoofer which is coupled at 80 Hz and driven by a separate 190 watt amplifier. Due to the universal design of its rear terminal area, the integrated active subwoofer can be activated by either the sub-out output of an AV receiver or the speaker terminals of your stereo amplifier. In any case, the amplifier/receiver is no longer required for bass reproduction, lending improved ease to the other frequency ranges.

Active/passive construction

The M 520 F offers a simple way to dramatically improve the bass quality of your stereo system or add two subwoofers to your home cinema system. A three-stage volume selector switch allows you to assign various weights to the subwoofer and tweeter/midrange ranges so that the column speaker can be adjusted to various space requirements. This active/passive construction is effective down to 30 Hz and can generate a breathtaking volume level of 105 dB/meter! This makes these column speakers capable of filling an entire 50 sqm room with sound.

D'Appolito configuration

The M 520 F provides clear proof that the easiest way to get the best results is to rely on “classical” methods: increased housing volume, large cone surface, solid chassis technology, proven D'Appolito configuration plus a great deal of “inspiration” (see active/passive subwoofer in the column speaker). As a result, this pair of M 520 F column speakers can deliver stereo sound whose quality will simply blow you away. Of that we are certain.
