The McIntosh MEN220 Room Correction System delivers acoustic calibration across a full frequency response of 20Hz to 20,000Hz with an ultra-low total harmonic distortion of 0.002%. Physical room boundaries, furniture, and reflective surfaces often distort the way sound travels from your loudspeakers to your ears. By analysing your specific listening environment and correcting room anomalies, the McIntosh MEN220 reveals the true tonal balance, instrument separation, and soundstage intended by the recording artist.Room Alignment for Pure Musical Clarity:Every room shapes sound differently, creating unwanted bass boom or harsh reflections that mask subtle musical details. The McIntosh MEN220 uses RoomPerfect calibration to measure acoustic reflections throughout your space and create a tailored correction profile. This ensures your loudspeakers produce clear, natural vocals and tight, balanced bass from any listening position.Integrated Crossover and Personalised Voicing:Beyond room correction, the McIntosh MEN220 includes a two-way electronic crossover and custom equalisation settings. This built-in crossover lets you blend subwoofers with your main loudspeakers seamlessly, directing low frequencies where they belong while keeping midrange vocals open and detailed. Balanced XLR and unbalanced RCA connections ensure clean, low-noise signal transfer between your preamplifier and power amplifier.Authorized Dealer:We are an authorized dealer for McIntosh.
