Bowers & Wilkins Nautilus 801 Review

The Bowers & Wilkins Nautilus 801, introduced in 1998, stands as one of the most significant loudspeakers of its era. It represents the full application of technology developed for B&W’s radical 1993 Nautilus “snail” speaker to the company’s long-running 801 monitor lineage (first launched in 1979 and famously adopted by Abbey Road Studios). The result was a thoroughly modernized three-way design that combined studio-monitor authority with domestic high-end refinement.

Design & Technology

The Nautilus 801 is a three-way, reflex-loaded floorstander with each driver housed in its own optimized enclosure:

• Tweeter: 1-inch (25 mm) aluminum-dome unit loaded by a tapered Nautilus tube that absorbs rear radiation and minimizes resonances.
• Midrange: 6-inch (150 mm) woven Kevlar cone using B&W’s Fixed Suspension Transducer (FST) technology, mounted in a spherical Marlan resin “head.” The surroundless design and tapered rear chamber reduce reflections and standing waves.
• Woofer: Massive 15-inch (380 mm) paper/Kevlar composite cone in a heavily Matrix-braced, curved cabinet. Bass is loaded by a downward-firing Flowport with dimpled surface to reduce turbulence.

Crossover points are 350 Hz and 4 kHz (third-order). The modules are isolated using IsoPath technology, and the cast metal plinth houses the crossover and dual sets of WBT terminals (bi-wiring/bi-amping ready). Finishes included black ash, cherry, and red-stained cherry.

Key specifications:

• Frequency response: 37 Hz–20 kHz ±2 dB (–6 dB at ~23 Hz)
• Sensitivity: 91 dB (2.83 V/1 m)
• Nominal impedance: 8 ohms (minimum ~3 ohms)
• Dimensions: 43.7″ H × 20.6″ W × 27.2″ D (1110 × 522 × 690 mm)
• Weight: 229 lbs (104 kg) each
• Original price: approximately $11,000 per pair

Sound Quality

The Nautilus 801 is defined by scale, dynamics, and low-distortion clarity. Reviewers consistently praise its ability to deliver realistic dynamic range and physical impact without strain. The large woofer produces deep, powerful, and articulate bass with genuine slam—capable of delivering the kind of low-frequency energy that is felt as much as heard. When properly driven and placed in a suitably large room, the bass is tight and well-controlled rather than bloated.

The midrange is a particular strength: clean, detailed, and notably free of obvious colorations, with excellent texture on voices, strings, and acoustic instruments. The Nautilus-tube tweeter contributes extended, relatively smooth highs that avoid harshness when the system is well matched. Integration between the three drivers is seamless, and the speakers create a large, stable soundstage with precise imaging and convincing depth.

These speakers perform at their best at realistic (live) volume levels. They can play extremely loud while remaining composed, revealing fine detail and ambient cues on good recordings. At lower background levels they can sound somewhat less lively. They are highly revealing of both the recording and the rest of the system—excellent recordings sound outstanding, while flawed ones are exposed without mercy.

System Matching & Practical Considerations

Despite the 91 dB sensitivity rating, the Nautilus 801 is a demanding load. The impedance dips and phase angles require amplifiers with strong current delivery—robust solid-state designs (Krell, Mark Levinson, etc.) are frequently recommended. Bi-amping often yields noticeable improvements in control and refinement. Tube amplifiers need substantial power and authority to succeed.

The speakers need a decent-sized room (many suggest a minimum of roughly 12 × 16 feet or larger) to develop their full bass potential and spatial performance. Placement is relatively forgiving once the room can support the low end, though careful positioning and spiking improve focus and slam.

Strengths

• Exceptional dynamics, scale, and bass authority
• Low-distortion, highly transparent midrange
• Excellent imaging and large soundstage
• Studio-monitor heritage with genuine high-end refinement
• Ability to play very loud without compression or strain

Limitations

• Large size and substantial weight
• Demanding of high-current amplification
• Requires a sufficiently large room
• Can sound less engaging at low volumes
• Revealing nature exposes poor recordings and system weaknesses

Verdict

The Bowers & Wilkins Nautilus 801 remains a landmark loudspeaker. It successfully translated the engineering lessons of the original Nautilus into a practical (if still imposing) high-end monitor that offered rare combinations of dynamic power, clarity, and musical authority. In a proper room with capable amplification it delivers a thrilling, large-scale presentation that few speakers of its era—or even many later ones—could match.

While later generations of the 800 Series (Diamond, D3, D4, and beyond) have refined the formula further with diamond tweeters, improved materials, and updated cabinetry, the original Nautilus 801 still holds a special place for its combination of studio credibility and high-end performance. For listeners who value scale, impact, and transparent midrange in a large-room system, a well-maintained pair continues to reward. It is a true classic of high-end audio.
