Supersonic....if this helps you out, I just posted this F1 review on Sweewater's website. I was an L1 user for years also. But it just seemed to lack that "punch" I needed when I played for bigger crowds. So I traded up to the F1. Here was what I wrote:
As a veteran DJ of 34 years, I've owned many sound systems over the years, and have tried several different leading brand names. By far, a pair of the Bose F1 packages (812s with subs) is the greatest system I've ever owned. I'm constantly striving for the "PERFECT" sound, and the flexible array of the 812 offers the opportunity to do that. And it all fits in a Ford Escape! Now that I've hit the age of 50, I wanted to get away from hauling the big 130 pound speakers and back-breaking subs I had before. Now, I still get the BIG booming sound those heavy old school subs and speakers had, without waking up with a sore lower back the next day! And if I'm doing a small event, I can leave the subs at home and bring just the 812's on stands. A flip of a switch puts them in "full range" mode, making for even less to haul in when you simply don't need all the extra low end! Clearly, Bose thought of everything a DJ needed here. Even without subs, the mains still offer plenty of amazing sound. But with the subs, the sound is just amazing! I can't tell you how many times people have come up to me and told me how clean and crisp my sound system is. Plus, with the design, it just looks totally badass! One more thing...it's Bose. Yes, it's a little more costly than the other brands. But I have complete confidence I'll set it up gig after gig, and it'll just work exactly as I need it to.
