    "best_for": "Professional main-monitor duty in medium-to-large control rooms and film\/post re-recording stages that need very high, low-distortion SPL (121dB at 1m) and full-range extension (25Hz-20kHz free-standing, 20Hz soffit-mounted). Suits rooms that can accommodate a ~925mm-wide cabinet and dedicate a rack space to the external ATC amplifier pack.",
    "who_should_skip": "Home, project, or near-field mixing setups, and anyone without a large, acoustically treated room. The cabinet is roughly 884 x 925 x 460mm and very heavy (140kg per datasheet, or 87kg per ATC's web listing), needs soffit or heavy stand mounting, and requires an external rack-mount amplifier plus a balanced XLR feed at 2V sensitivity.",
    "fit_notes": "Three-way active design: 34mm soft dome tweeter, 75mm ATC Super Dome midrange, and twin 15in SL bass drivers, tri-amplified by a rack-mount ATC 4-way grounded-plane 850W amp (Bass 275+275W, Mid 200W, High 100W). Crossovers at 380Hz and 3.5kHz with even-order critically damped filters. Coherent dispersion is ±80° horizontal \/ ±10° vertical, so vertical listening window is narrow -- tweeter\/mid height alignment matters. This listing is a single cabinet; a stereo pair requires two.",
    "watchouts": "Weight is a genuine source conflict: ATC's printed A4 datasheet states 140kg (308lbs) while the atc.audio product page and several retailers state 87kg (191.4lbs) -- confirm shipping\/rigging weight with the seller before purchase. Professional-range cabinets are shown in black in ATC's own imagery, but no cited source gives an explicit finish\/color spec, so color is left unset. No MPN or GTIN could be sourced. The 850W figure is a total-amplifier rating; per-band outputs (275+275\/200\/100W) come from the datasheet. Passive versions of this model exist per the datasheet footnote, so verify you are buying the active (ASL) variant.",
