Definately get yourself a sub! Just dont have your system turned up before 9 am and turn it down after 9pm and you should be fine. You can allways turn the gain down and also be sure to buy this sub mat
I got noise complaints just watching tv or listening to music at loud but reasonable volumes with bookshelf speakers on stands. Bought these, neighbours said noise completely disappeared:
My apartments has concrete flooring, and my wife and I bought one of these
Subwoofer Dampening Pad
I've asked my neighbor, and he says he's never even heard it, and it's a pretty big sub.
I doubt either would make a large difference. The wavelength of bass frequencies are very long. If you aren't in an apartment you shouldnt be disturbing the neighbors. If you are truly worried about disturbing you could pick up an isolation pad.
By touching I'm assuming you mean the enclosure? If it's just the enclosure that shouldn't have an impact. If you're talking about that actual woofer then that curls damage the woofer.
Something like this is cheap and will totally eliminate any energy transfer to the floor, especially on a small sub.
The only other thing that will help is to reduce the level of the sub or turn it off at night when others are sleeping.
Second this. We use this & neighbors hear nothing (we also live in a steel & concrete house):
Sound Dampening Speaker Riser Foam - Audio Acoustic Noise Isolation Platform Pads Recoil Stabilizer w/ Rubber Base Pad For Studio Monitor, Subwoofer, Loud Speakers - Pyle PSI15 (15 x 15 x 1.8 Inch) https://www.amazon.com/dp/B00SVRLR06/ref=cm_sw_r_cp_api_i_T.3dFb6ZACM8B
The problem is that the bass just carries. Putting stuff on the wall will filter out the highs but the thump thump thump lives on.
If you're only hearing the bass ask them to lower the bass level a bit and see if it helps. If they sit the speakers on an isolation pad that prevents the bass from being transferred to the building that really help too.
I'm looking at subwoofer isolation pads. I saw this guy, but I'm skeptical of Pyle gear : https://www.amazon.com/Pyle-Subwoofer-Isolation-Stabilizer-Loudspeakers/dp/B00SVRLR06/ref=sr_1_5?ie=UTF8&qid=1512585855&sr=8-5&keywords=subwoofer+isolation
Acoustic Isolation Platforms are your friend. I have hardwood and this cut the floor rattle for me. It also tightened the bass up as well. It is the best bang for your buck item that I have bought.
I just got this subwoofer mat and it takes away the rattles
Grab youself a 8/10 inch sub and asubwoofer mat like this and you shouldnt hear from your neighbors
What kind of Yamahas? These might do the trick
You could try something like this: Sound Dampening Speaker Riser Foam - $34 (USD)
If you're not in the USA, then just search for something similar in your country.
I have a NHT sub sitting on a wood floor. Even at very, very low volumes it shakes the house enough to wake my spouse upstairs and two rooms over. Would a dense foam pad help? Like this Pyle or this Auralex?
