I don't post here very often (I don't know if I ever have actually), and although I've never heard the system that Heath has, I'm sure it's pretty good. (I've known him for a long time, he always wants to have the best stuff, good for him, bad for his checkbook)
And sorry, I don't DJ anymore, but I did for almost 20 years, so I do have a DJ background, so maybe you'll accept my poking my head in here once in a while?!
I am somewhat familiar with one of the Dynacord systems, and I can say I'd take it over a Bose system any day, and I have used an installed Bose PA system before in a bar. I believe it has 2 of the 802's (or whatever their pro line is). It sounded very good in the vocal range, I'll give it that. however, the highs weren't what I would call crisp. The lows were smooth, but not punchy. I don't know what subs they had though.
From the Dynacord system that I've heard, the bass is very tight and has considerable punch, and the highs were nice and crisp. I will say that they get a little harsh in the 3-5k when pushed, but nothing a little EQ can't take care of on the fly if one really wants to push it that hard.
I have heard the L1 system also, again, although only on spoken word, and they sounded good for that, but I wouldn't want to put on a show with them, I think they'd hold up very well. great for simple vocal applications and some acoustic stuff probably, but nothing with much dynamic range.
Another thing I've noticed with Bose 802 type speakers is listener ear fatigue. A friend of mine has 802 house speakers, and after listening to them for an hour or so, my ears just seem "tired", and I noticed that in the bar also. I don't know if it's because I'm straining to hear the upper end clarity that I want, or if it's all the different drivers pointed in different directions. They do sound good at first, and you think, wow, this sounds big and full, but just not in the long term setting, after a while, my ears get tired of deciphering all the reflections. I guess I'm a "point-source" type of guy.
These are my personal opinions though, please no flames or anything, just stating a few of my observations from personal experience.
I'll take my chances and jump on the Dynacord bandwagon also. It's very spendy, but very satisfying, not only for your own personal satisfaction of owning a top-notch system, but for the satisfaction of having people all over the place come and comment on the clarity and tonal balance of your system.
