    • Best small room sub
Style: Single
Killer Sub, base fills my small living room and shakes everything in it! But its clear and crisp base with no feedback or rattling. High quality. I am a big fan of Yamaha products and this only made me more of one.

    • Excellent small, value sub
Style: Single
I bought this mini sub when I was living in my apartment because I’m a big movie person, but didn’t want to piss off the neighbors with a larger, true HT sub (plus I was on a tight budget), and was very pleasantly surprised. It’s only an 8” driver, so you can’t compare it to a 12” or bigger driver, that’s not realistic, but it’s fantastic for what it is. This thing rumbles and it has a nice tactile punch to it. I never turned the gain knob up past 5/10. I would absolutely recommend this sub for anyone with SPL (volume) limitations, neighbors, or financial limitations. At 8” it just physically can’t get down ultra low or provide the fullness a bigger driver can, but man does it try, and if you’ve never experienced anything bigger, you won’t be missing anything. I would be very interested to listen to the 10” version, the NS-SW100. Overall, I was thrilled with it for the size and price point at the time when I built my budget 5.1 system. It really is a fantastic little sub and I would absolutely purchase it again. If you have a bigger room or want a true HT sub, you’re gonna have to be realistic and go bigger and a lot more expensive. Otherwise, get this thing (or the 10” NS-SW100) and enjoy! ... show more

    • Two subs are better than one
Style: Single
This sub delivers clean tight bass and does so without too much muddy sound. Its hard to beat at this price point. The eight inch woofer may not go down quite as deep and bigger ones, but it sounds really great in my twin sub arrangement with one on the left and one on the right side of my room. This opens up the sound stage quite nicely. I only wish it had the instant on feature. I have to reach down and flip the switch on the back for on and off. oh well. ... show more

Style: Single
The media could not be loaded. Fantastic subwoofer! I am beyond impressed. It's a compact beautifully-designed powerhouse that utilizes it's resources accurately and dutifully to produce wonderfully musical and melodic bass. Highly recommended to anyone in pursuit of that full sound and listening experience. I have my crossoverv at 80hz and -1db on my receiver. It's a Yamaha and it's quite nice. ... show more

    • Great sub!
Style: Single
Great sub for the money and smaller size so easier to hide, does not have a frequency adjustment but that’s my only complaint, really good base from only an 8” sub. Get what you pay for and Yamaha has always delivered

    • Great bottom end
Style: Single
Full disclosure; I'm Rebecca's dad, not Rebecca. I ordered the Yamaha sub to replace an aging passive subwoofer. Modern 5.1 systems are set up for an active subwoofer and, frankly, they need one! The Yamaha fit the bill. It was priced right, including a 15' cord to connect back to the receiver & allow the sub to be placed where I want it in the room. The results? Fantastic. 8" doesn't sound like much, but the Yamaha puts out an impressive sound. When I listen to music, it provides that low underpinning of sound that is hard to get from a standard speaker, or from an old fashioned passive subwoofer that simply lacks the volume needed. For movies, it has transformed my sound into a chair-rumbling experience. As soon as the speaker was set up, I gave it a good shakedown test - Star Wars, then Independence Day. The Yamaha delivered the kind of theater experience I've been looking for. Some people have asked if it is loud enough. Absolutely. The subwoofer itself has a volume control, which I leave at full volume; that allows me to control volume through the receiver with the remote. For most movies, keeping the SW channel just above 50% is just right; for a few action movies, such as Independence Day, I had to back it down to about 40% - high enough to feel the rumble, but low enough to hear the dialogue through the center channel. I'm sure there are some better subs out there; just depends on what you think you need. For me, the Yamaha subwoofer is a perfect match. For reference, my system is: a Denon 5.1 receiver, 2 Bose 201 speakers for front channel, and 3 Sony bookshelf speakers for center and rear channels. ... show more
