LA400's suck suck suck in anything less then 4. They struggle to get below 50hz in 4's, but really don't do much below 55hz in singles. I did a show last year with 2 per side, and while they hit pretty good, the ass is just not there. I was only hearing harmonics of the lower notes rather then the actual note.

I think you had some improperly configured LA400s then. Like pretty much any other horn, and specifically for the LA400, they have a rising response up through 100hz so if not properly EQ'd they will seeming lack output on the lowest octave of their usable range.
I have used them two per side for several years now, and I have had NO problems with their frequency response. And according to my ears, RTA and measurement mic, they have plenty of output below 50 down to about 45Hz. Yes, in blocks of 4 they really shine. They gain about a half octave of extension.
A few gigs made me question myself over the years, but the next show with a drummer that knew how to properly tune his kick drum, changed that.
That said, there are those that are never satisfied (like yourself) and always want more low end. Because more is always better, right?

LAB's are the best option, but they are HUGE and don't do so well in singles. They'll do fine in pairs, but singles, not so much.

The LAB sub definitely has about 6-8dB more output than an LA400 below 50hz. They also weigh nearly twice as much, are 10 inches deeper and taller, and have TWO drivers versus one. LAB subs are fantastic, I will be the first to support that argument.
That said, it's an apples to oranges comparison IMO. It's like comparing an SRX718 to a B2.
