MAGICO MXO ACTIVE ANALOGUE CROSSOVER FOR MAIN SPEAKER AND SUB INTEGRATION

Magico of the USA has announced the new Magico MXO Active Analogue Crossover.

The Magico MXO is the active analogue crossover originally conceived and designed for the M9 loudspeaker system (at 120Hz fixed). It will now also be available with high/low pass filtering (at 55Hz fixed).

Implementing the same MXO platform, this purpose-built version will benefit Magico end users worldwide looking for subwoofer and main speaker integration. The MXO provides high/low pass filtering which relieves the main loudspeakers of the low frequencies below 55Hz and sends extended low bass information to the powered subwoofers.

Magico says that this level of upper and lower range signal management improves transparency and resolution in the main loudspeakers and allows the powered subwoofers to seamlessly integrate with the main speakers.

LINKWITZ-RILEY FILTER SLOPE

The Magico MXO features an Active 2-Way, 24dB/octave, Linkwitz-Riley filter slope at 55Hz with a 0/180-degree phase option and 12dB gain per channel. Designed in-house, the MXO is a dual mono, fully balanced / discrete circuit topology design from input to output using quality precision resistors and capacitors.

MODULAR CARD DESIGN

Precision step attenuators provide 0.5 dB/step control with up to +/- 12dB of gain adjustment per channel using a proprietary design. The unique gain stage features software driven relays to control the circuit. A propriety technique is implemented to have one fixed resistor in series while maintaining a constant output impedance during volume changes to achieve optimized sound performance at all volume settings. The open architecture of the MXO uses a modular card to motherboard design that enables the implementation of additional filter topologies or upgrades in the future.

DUAL CHASSIS DESIGN

The dual chassis design of the Magico MXO isolates the sensitive filter processing circuitry from the separately housed power supply. Featuring oversized lab grade power transformers, the power supply regenerates AC and applies active regulation across every stage of the circuitry.

HiFi Pig Says: This may sound like a lot of money but I imagine if you are intending to get the Magico M9 and the Magico Titan 15 subwoofer, then that might not be too much of an issue.
