A pair of floor-standing speakers from Yamaha with two 16 cm cone woofers and a 3 cm soft dome tweeter in a two-way bass-reflex design. Yamaha lists 43 Hz to 26 kHz response, 80 W nominal input power and 6 ohms impedance.

This is a REFURBISHED item, direct from Yamaha, and comes with half of the standard warranty (normally 2 years, so 1 year with this unit).

Yamaha describes the NS-F51 as a floor-standing speaker for home theatre. It says the speaker suits large-screen TVs and works with movies and with sources such as CDs, MP3 and streaming music.

Why you will love it

Two woofers and a soft dome tweeter

The NS-F51 is a two-way, three-speaker design. Yamaha says the two 16 cm (6-1/2") cone woofers and one 3 cm (1") soft dome tweeter give strong bass and smooth full-range sound.

Yamaha says the large-capacity cabinet produces thrilling bass tones, while a bracing system suppresses cabinet resonance for clear treble. It also says a wooden circuit board is used in the network circuit.

Rounded form and grille

Yamaha says the cabinets are rounded to reduce the diffraction effects that cause murky sound.

The front grille has slanted corners, which Yamaha says brings to mind its flagship speakers. Yamaha describes a high-texture wood grain cabinet.

    Yamaha NS-F51 Floorstading Speakers

    I received my Yamaha NS-F51 Floorstanding speakers at my home in Victoria last week. They work excellently and are exactly what we were hoping for. The karaoke performance is especially impressive, creating a fantastic balance between the vocals and background music. They also deliver rich, solid bass and crisp treble when listening to blues.

    I ordered the items online and then spoke to Jamal in customer service just to make sure my order had gone through. Jamal clearly explained all the specifications to me, and my items were dispatched straight away on the same day. After that, they kept me updated on the delivery progress.

    In summary, I highly recommend this supplier (Todds HIfi). I rate them highly for their excellent communication and honesty, and their prices are very competitive compared to similar items on the market. I will definitely buy from them again in the future.
