Experience MartinLogan Magic: Motion Foundation F1 Floorstander – Black Open Box Excellence!
Ready to unlock electrostatic-level detail in a floorstanding powerhouse? This MartinLogan Motion Foundation F1 (FF1B) in glossy Black is your open box gateway to premium hi-fi – like-new, meticulously tested, and loaded with the innovative tech that made MartinLogan a legend. Sold as a single speaker (perfect for building pairs or systems), it originally retailed at $849 and delivers stunning performance for music lovers and home theater enthusiasts. Slim enough for modern spaces yet commanding in soundstage, it's ideal for rooms 150-300 sq ft.
Why the Motion Foundation F1 Stands Tall MartinLogan's Foundation series democratizes their flagship electrostatic sound with affordable, high-tech drivers. The F1's Gen2 Obsidian Folded Motion XT tweeter – an air-motion transformer – radiates ultra-wide dispersion for pinpoint imaging and silky highs without fatigue. Paired with precision aluminum cone drivers, it crafts a seamless, holographic sound from whisper-quiet vocals to explosive dynamics. Reviewers call it "a mini-Motion 60i" for its speed, clarity, and bass authority – punching way above its price point.
Key Features & Specs at a Glance:
Design: Elegant 3-way floorstander (41.42" H x 8.38" W x 14.43" D; ~35 lbs) – Slim profile with curved cabinet for reduced resonance; includes outrigger feet and spikes for stability. Drivers: Gen2 Obsidian Folded Motion XT tweeter (for airy, extended highs) + 5.5" aluminum midrange (detailed vocals/instruments) + three 5.5" aluminum woofers (deep, controlled bass down to 41Hz). Frequency Response: 41Hz - 23kHz (±3dB) – Captures sub-bass rumble to sparkling treble. Sensitivity: 91dB – Easy to drive with most amps/receivers (20-200W recommended). Impedance: 5 Ohms – Stable load for quality AVRs; bi-wire/bi-amp capable. Enclosure: Bass reflex with dual rear ports; Folded Motion waveguide for wide sweet spot. Build: Black gloss finish with magnetic grille; Vojut surround tech for low distortion; USA-made quality. Extras: Hi-Res Audio ready; integrates seamlessly in 2.0/2.1 stereo or 5.1+ surrounds. Open Box Condition: Pristine & Plug-and-Play This F1 is open box – unused after initial QC. Zero cosmetic flaws – a couple hard to see light scuffs, dust, or marks – and we've verified: Full driver excursion, balanced frequency response, no rattles. Includes:
Original double-box packaging. Owner's manual and spec sheet. Spike feet kit with carpet protectors. Cleaning cloth. All factory-fresh, just minus the outer seal. Pro Tip: Pair with a Denon AVR-X2800H or NAD C 368 amp for a sub-$2,000 system that rivals $5K setups. Crutchfield and Audio Advice users give it 4.8+ stars for "addictive detail" in jazz, rock, and films – "bass that's tight, not boomy."
