Big, full range, dynamic sound in a larger room at home generally requires either
1) large full range higher efficiency speakers like the JBL that do not require a lot of power to go deep and loud and clear or
2) smaller less efficient speakers and a high power amp to drive them. High power amps up to the task traditionally large, heavy and expensive, but not longer with newer high efficiency amp technology, like Class D switching amps.
...take your pick.
Smaller rooms at home are less of a challenge, especially if you do not need flat response down to 20 hz. Flat response down to only 50-60 hz or so does not require as much to get the air pressurized as needed, especially in a smaller room.
Luckily, few people have rooms the size of even a small concert venue at home, so that opens up more possibilities in regards to what it takes to sound really good.
