Also thick carpets even whole room and those theater non flammable curtains on windows could help you a lot

 

LOL

 

In the 2000's I gig as a DJ a lot on night clubs, never saw one that could stop the sub leakage. Its a real problem

 

Addressing the source of the subsonic sound is crucial. You should provisionally use an EQ (on your analog gear, or a digital one somewhere in the chain) or a subsonic filter to reduce subsonics when convenient (especially at night), at least at times in your workflow when they are not the main concern. Additionally, you should keep your listening volume at reasonable levels, especially considering your neighbors.
Place your loudspeakers on spikes to isolate them from the foundation. This decreases the transfer of unwanted vibrations from the speaker enclosure into the floor and vice versa. The connection with the base should not have compliance (elasticity) because the sound gets blurred due to vibrations of the loudspeakers, which are freed and boosted by the elasticity of its coupling to the ground (or even get into resonance). So do not resort to using rubber feet or other vibration isolation pads. A sandbox is a slightly better solution but suffers from the same shortcoming.
Put a small (or a cut piece of) heavy carpet (or thick rubber foam) in front area of each loudspeaker to absorb the low frequencies, which will partially prevent the bass from hitting and bouncing off the floor, and hence also from hitting the walls.
Adding elastic mass-loaded material to walls or ceilings can help absorb and dampen sound, although it is costly and doesn’t always look nice.
Sealing gaps around windows, doors, and other openings and keeping them all shut can prevent some sound leakage from your apartment.

i was thinking of the thick curtains. I have two small windows, so the cost shouldnt be too bad. Also thinking of laying down thick vinyl on the floor, with a thick carpet on top.

 

Curtains don't seem to do anything for low frequencies.

 

I didn't notice you mention how you've treated your home studio. I would suggest you consider using Owens Corning Fiberglass panels. You can install them without making any permanent alterations. Type 703 is the standard, but since you are more concerned about bass frequencies, perhaps Type 705 would be better since it is more dense. You could even use it to make bass traps to deal with the build up of lower frequencies

 

never been in a venue that uses the box in box solution? i've performed in several clubs that used this principle, basically they use the same principle as the rubbers for underneath speakers to stop the vibrations but then for the entire room

 

here's a good article on low frequency trapping.

https://www.gikacoustics.com/understanding-different-bass-trapping/

from the article:
There are many types of different bass trapping and low frequency treatments available for recording studios, control rooms, home theaters, and listening rooms alike. Whether you’re looking at tuned traps, resonators, membrane absorbers, or porous absorption – most can be broken down into two categories: velocity based absorbers, and pressure based absorbers. The terms “velocity” and “pressure” don’t describe their inner workings, but instead describe their optimum placement in a room. Pressure based treatments are most effective at areas of high sound pressure in the room, whereas velocity based treatments are most effective at areas of high particle velocity. This article is written to give you an idea on the differences of bass trapping, and how to use them to create the ultimate listening space catered to your preferences utilizing both.
