Review Image by M to the ARV

I previously owned and operated a professional home studio so I’ve heard my fair share of high end “monitor” speakers and subs. As such, I currently run Dynaudio Lyd 48s in my small 5.1 home theater ($2400.00 a pair). My Dynaudios are 3 way speakers. They create extremely clear, accurate sound and dialogue that diminishes most stand alone center channels by comparison. They also go down to 32 hz without strain which is already very low. I added this sub because I couldn’t justify spending 3x or more as much for just a few more hz of low end. That being said, I can honestly report that this budget Yamaha keeps up just fine for home cinema. With a frequency response that goes as low as 27 hz, you will be hard pressed to find anything better at this price point. Fellow Audiophiles will scoff at the fact that I’m running a $200 sub next to speakers that cost more than 12x as much after taxes. But with 20 years of critical listening, Im qualified to use my ears to judge. Might I purchase a more expensive sub later? Maybe. Will I be able to tell a difference? Sure. But not by much. This is a great investment for any small to medium sized room. I wouldn’t recommend it for mixing - the frequency response is far from flat and the lack of adjustability does not allow for crossover/fine tuning. But for the average consumer, this thing is exactly what you want; It’s small, simple, powerful, and will make your music and movie watching experiences fun! I’m not sure how Yamaha did this for $200. The flared port must be something from a magical land. The bass is tight and low enough to enjoy 90% of films without showing signs of stress. Only a few movies will reveal its weaknesses. You’ll have to search to find those (I’ll give you a hint… Dune). But at this price, you’ll forgive it. You’ll love it. It will be your friend. Just buy this thing. if your room is too large and you’re on a budget, buy 2 and don’t look back. Rest assured, you won’t be disappointed. ... show more

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

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

Best small room sub

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.

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

Wow. This is one of the smallest subs you can find but wow can it fill a room. I bought the “open box” and saved. It was brand new. Indistinguishable from new. Well done
