I don't think line arrays, work well in the home. I used a line array system I designed from 1977 to 1984, But I was never truly happy with it. Even though it was in a fairly large basement, you could never get far enough away from it. On the other hand I have done line arrays for large halls a couple of times, and they were very successful.
The thing about bass is that it has to be balanced and non resonant to be realistic. Don't get me wrong, if the rest of the system is excellent, then gilding the lily with clean balanced bass to 20 Hz or so completes the system. Rough crude resonant bass I so often hear is a detriment. My system covers the last octave but it is balanced, and you don't really notice the bass extension of the system, until there is low bass and sub bass to be reproduced.
Jonathan Scott gave a fantastic symphonic organ Prom on August 29, from the mighty Willis Organ of the Royal Albert Hall. It is still up on iPlayer. The BBC announcer said her internal organs were vibrating. This system also made my internal organs vibrate, but the system was at a realistic volume, and even the gentle 32 ft stops cold be felt internally. However you do not have to have enormous subs to enjoy music. However if any of the spectrum from 80 Hz up is missing or badly reproduced, then the whole experience quickly becomes endurance and not pleasure.
