Bass sensation like a loud car system in home?

Most all these answers will never give you what you want. You just need one subwoofer from Stereo Integrity and it is 24 inches in diameter and will handle 5000 W and has an 85 pound magnet on it and it will move 5 inches peak to peak travel and has audiophile quality sound.  It will change your whole reference for what subwoofers can do . Believe me you need to FEEL the bass.

@phusis , You could do two floor to ceiling towers in the corners with four 12 subs in each tower and get decent results and here is why I do not do it that way. It is virtually impossible to control resonances and vibration in an enclosure that big. The problem with most subwoofers is they are not just speakers. They are musical instruments. Enclosure design is not so simple. Any vibration or shaking of the enclosure is distortion. Keeping the enclosure from becoming a musical instrument requires a very heavy stiff walled enclosure. The Stiffest enclosure would be a sphere. Spheres are unfortunately hard to make and work with. Next in line is a cylinder. Put a driver in each end of the cylinder and you cancel forces that want to shake the enclosure. A heavy cylinder with 1.5" walls will not resonate. No resonating and no shaking. Perfect. Place four of these units along the front and in the corners and you have an extremely low distortion horizontal line source. If you recall. line sources do not radiate sound off the ends, in my case the sides! The subwoofer line source system has only one early reflection, the ceiling. My listening room is open to the kitchen and then the dining room. The nearest full wall is 75 feet away. I still have some nodal behavior in the room but it is greatly diminished. It sounds like you are in a much larger room. 

Getting a horn to do 18 Hz requires an extremely big horn. I know of one fellow who casted bass horns in his house's foundation. The drivers were in the basement. The horns curved outwards and upwards opening up at the bottom of the front wall making a "U" turn. I only saw pictures. This was before DSP. Those drivers had to 15 feet behind the rest on the system. That is a huge delay. I have screwed around with delays just to see what I could detect audibly. 1.5 ms is clearly audible in the midrange.
If your subs crossed over like mine at 120 Hz 1.5ms would also be clearly audible. Much lower and you would be able it pick it out in an A/B comparison. It gets more difficult as you go lower. It becomes not what you hear but what you feel. 

Let me put it this way: with my new (last couple of weeks) sub placement, I am now getting bass so powerful that I can’t imagine something similar in a car. It would be far too distracting and therefore dangerous. 

I listen to almost all genres of music. Some of them require some thud to the bass, even classical. It’s nice to FEEL the cellos and double bass at the end the adagio to Mahler’s 5th under Karajan’s wand. 

The one genre I almost never listen to is rap: with the exception of a handful of artists such as Notorious BIG and going back to Grandmaster Flash, I find it to be too misogynistic and with a range of emotion that rarely ventures beyond vicious anger and violence.

Have you tried cranking up the volume then listen from outside (exterior windows and doors closed) ? It may not be as loud as you think

Maybe you can borrow or get a returnable sub to evaluate the exterior sound leakage.

Tolerance of other home noise is dependent on the neighborhood. I have neighbors who occasionally have parties and “occasionally” jack up the music at “reasonable” (non sleeping) hours which I don’t mind because sometimes people just need to cut loose (destress) usually on weekends. So chances are it’s ok to jack up music occasionally during reasonable hours.

Or you can play better music that your neighbors enjoy :)

I'll stand by my initial post, rude as it may be considered.
I've heard wayyy too many auto 'bassers' loosening the bolts in their cars with just floppy butt bass...therefore, the 'bowels' inference....🤨

An approach could be multiple large drivers for the audio/tactile point, transferring to tactile drivers in the seating. (Drivers first, bolt seating Down second....)

Complex?  Perhaps....how far you want to go with your concept and desire?  Likely the answer could get complex and expensive depending on the results desired....

I like big bass too....relative to the genre', of course....;)

Good luck, J
