I actually had two L1s and two subs. They sounded fantastic, but it was way overkill for what I need.
After I got two Bose Compacts they sat in the garage for about a year, then I sold them. I just don't play real big jobs anymore.
Use whatever you think is necessary. Everything made these days is probably way better than what we used for years.
I'm happy with my system, until something I like better comes along.
