Yamaha NS-800A

Manufacturer: Yamaha

The Yamaha NS-800A is a passive bookshelf speaker designed for home audio use, featuring a 2-way bass reflex enclosure that houses a 6″ main woofer alongside a 1″ tweeter. Each unit weighs 13 kg and measures 231 mm wide, 420 mm tall, and 358 mm deep, giving it a substantial physical presence suited to dedicated listening setups.

On the technical side, the NS-800A covers a frequency range from 40 Hz up to 100,000 Hz, with a high-frequency crossover point set at 2.6 kHz. It carries a nominal impedance of 6 ohms and accepts a continuous RMS input of 40 W, with a peak handling capacity of 120 W. The speakers are not wall-mountable and come with a 2-year warranty.

Pros
  • The bass reflex (ported) enclosure design supports a low frequency extension down to 40 Hz, which is relatively deep for a bookshelf form factor
  • The wide frequency range reaching up to 100,000 Hz means the tweeter reproduces well beyond the standard audible ceiling
  • A 2-way driver layout with a dedicated 1″ tweeter and a 6″ woofer provides a clear division of frequency responsibilities across the spectrum
  • The 2.6 kHz crossover point gives the 6″ woofer a substantial portion of the midrange to handle before handing off to the tweeter
  • The 2-year warranty offers a reasonable coverage period for a passive speaker product
Cons
  • At 13 kg per unit, each speaker is quite heavy, which can make placement and repositioning inconvenient
  • The speakers are not wall-mountable, limiting placement options to stands or furniture surfaces only
  • A continuous RMS input rating of 40 W is relatively modest, meaning they require a carefully matched amplifier to avoid underpowering or clipping
  • The bookshelf form factor combined with the 420 mm height and 358 mm depth means each cabinet takes up a meaningful amount of shelf or stand space
Who is this for?

The NS-800A is well suited to listeners who want a dedicated stereo listening setup in a mid-sized room, where the bass reflex enclosure and 40 Hz low-frequency extension can be properly exploited without the room overwhelming the speaker's output. The 2-way driver configuration with a clear crossover at 2.6 kHz makes it a solid match for users who value clean midrange and treble reproduction, and the 120 W peak power handling gives flexibility to pair it with a range of passive amplifiers. It also suits buyers who prioritize long-term reliability, given the 2-year warranty coverage that comes with each pair.

Who is this NOT for?

The NS-800A is not a practical choice for users who need flexible speaker placement, since the lack of wall-mounting capability restricts installation to stands or flat surfaces only. At 13 kg per unit, the speakers are also poorly suited to anyone who needs to move or reposition them frequently, making them a poor fit for temporary or multi-room setups. Additionally, users working with lower-powered or entry-level amplifiers may find the 40 W continuous RMS rating leaves little headroom, and the considerable cabinet depth of 358 mm means the speakers are impractical for shallow shelving or space-constrained environments.

Final Verdict

The Yamaha NS-800A is a passive bookshelf speaker that makes a compelling case for dedicated stereo listening, thanks largely to its wide frequency range spanning 40 Hz to 100,000 Hz and a well-structured 2-way bass reflex design that handles both low-end body and high-frequency detail with clear driver responsibility. Its substantial build and fixed placement requirements mean it rewards users who can commit to a proper listening environment with suitable amplification and stable speaker stands, rather than those seeking a versatile or easily repositioned solution. For listeners who can meet those conditions, the NS-800A represents a thoughtfully engineered passive speaker with solid power handling headroom and a warranty that reflects reasonable long-term confidence in the product.
