Yamaha NS-IW470 3-Way 6.5″ In-Wall Speakers — Pair, Black
$175.00
The midrange and tweeter both swivel, so you can aim them at the seat rather than at the opposite wall — useful in a room that is not symmetrical. A 6.5-inch coated paper woofer, a 2-inch paper midrange with its own level control, and a 1-inch silk dome. 55 Hz to 28 kHz, 6 ohms, wired internally with Monster Cable. Light traces of a previous installation, no damage.

Yamaha NS-IW470 3-Way 6.5″ In-Wall Speakers — Pair, Black
A pair of Yamaha NS-IW470 three-way in-wall speakers in black — a versatile, easy-to-install system built around an impressive crossover network and swivelling high-frequency drivers, showing minor signs of a previous installation but no noteworthy flaws or damage.
Yamaha’s NS-IW470 is a capable and well-engineered in-wall speaker that punches above its modest footprint. The three-way driver complement — a 6.5″ coated paper cone woofer, a 2″ paper cone midrange, and a 1″ silk soft dome tweeter — covers a wide frequency range of 55 Hz to 28 kHz, and the swivel-mounted tweeter and midrange allow precise aiming toward the primary listening position. This is a genuinely useful feature in asymmetrical rooms or installations where the listener is not directly in front of the speaker.
The crossover network is a particular strength of this design. Yamaha engineered a low-distortion, high-capacity custom crossover that preserves transient integrity across the frequency band, and the internal wiring uses Monster Cable throughout — a detail that speaks to Yamaha’s intent to deliver a clean, uncompromised signal path from input to driver. A level adjustment control for the midrange allows fine-tuning to suit the room’s acoustic character or listener preference. At 120 watts peak / 40 watts nominal, these speakers have ample headroom for home theater or whole-house audio applications.
These speakers have been thoroughly inspected and tested to confirm full functionality. Cosmetically, both units show minor signs consistent with a previous installation — light traces of paint or mounting contact on the frames — but present cleanly with no damage, broken clips, or driver flaws of any kind.

Yamaha began as an organ maker in Hamamatsu, Japan, in 1887. It made gramophones from the 1920s and began hi-fi with the 1954 HiFi Player. We carry Yamaha AV receivers, vintage stereo receivers, CD players, subwoofers and speakers. We've had more than 280 Yamaha listings so far, covering nearly 200 different models. Every used Yamaha here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Every AV receiver we list is tested input by input on our bench: each HDMI input and output, the analog, optical and coaxial inputs, the subwoofer outputs and the wireless features where it has them. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.
Yamaha models we've sold most often: the SW-3 subwoofer, the NX-E270 surrounds, and the RX-V1400, RX-V850 and RX-V800 AV receivers.
The Yamaha hi-fi story
Torakusu Yamaha built his first reed organ in Hamamatsu in 1887 and founded Nippon Gakki in 1897; the company was renamed Yamaha Corporation in 1987. Yamaha calls the 1954 HiFi Player its first audio product, and dates its first Natural Sound (NS) speakers to 1967.
1970s hi-fi. The CA-700 and CA-500 of 1972 were Yamaha's first integrated amplifiers, and the CA-1000 of 1973 could switch its output stage between Class A and Class A/B. The NS-1000 and NS-1000M speakers of 1974 used beryllium dome drivers, and the NS-10M of 1978, sold for home use, became a studio monitor.
CD and surround. The CD-1 of 1982 was Yamaha's first CD player. The DSP-1 of 1986 was a Digital Sound Field Processor, and in 1993 the RX-V870 became the first Yamaha receiver with CINEMA DSP. The RX-V992 of 1997 added built-in Dolby Digital decoding.
AVENTAGE. The AVENTAGE (RX-A) receiver line launched in 2010, above the RX-V range.
Which Yamaha is which?
CA integrated amplifiers (1972 to about 1979): the CA-500, CA-700, CA-1000 and CA-2000, followed by the A-series.
CR receivers (mid-1970s to about 1980): the CR-1000, then the CR-620 to CR-2020 generation of 1977 to 1979.
NS speakers: from the NS-690 and the beryllium NS-1000 to the NS-10M bookshelf speaker, made from 1978 to 2001.
CD players: from the CD-1 of 1982 to the CDX and GT-CD models.
RX-V AV receivers (from at least 1991): such as the RX-V800, RX-V850 and RX-V1400 we sell often. Built-in Dolby Digital arrived in 1997, YPAO room calibration in 2003 and HDMI in the mid-2000s.
RX-A AVENTAGE (from 2010): the step-up AV receivers. The RX-Z models were the flagships until 2007.
Buying used Yamaha: what to check
Formats. On an AV receiver, check what it decodes and connects to: Dolby Digital from 1997, room calibration from 2003, HDMI from the mid-2000s.
HDMI boards. On modern AV receivers, HDMI is usually the first thing to fail. We test every HDMI input and output before listing.
CR receivers. Owners suggest asking whether service bulletins were done on a CR-2020, and expect scratchy controls and burnt-out dial lamps on any unserviced unit.
NS speakers. Check that the tweeters on an NS-10M are original and both work, and inspect the beryllium domes on an NS-1000, since Yamaha stopped making beryllium diaphragms in 1997.
Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
