Yes I have, many many many times. One of my very first "audio buddies" here in Denver had a pair of Apogee Full Range speakers set up in his dedicated basement. Paired them with dual floor to ceiling DIY subs, and the rest of the equipment was Ayre at first, but eventually all got replaced by Pass Labs, the X250's I believe.
There's things I love about the Apogees - first, they are big, so they scale up in a way that small speakers just can't. Second they are open baffle so they have the effortless sound that box speakers have a very hard time replicating. And with those crazy Pass amps, they were also quite dynamic.
The downsides - they always sounded somewhat aggressive and with a bit of and edge to the sound. It was less noticeable at lower volumes but started to rear up with moderate and high levels. Not sure if it's because they were metal but I suspect it was. And they never sounded fully integrated even if you sat a fair bit of distance away from them. Last, but not least, bass without a sub was not strong/deep enough (although it was very clean/musical), and integrating a sub (or subs) was a nightmare.
In comparison the Lineforce has none of those problems. One of the things that amazed me so much about this is their ability to go loud on a dynamic peak and not sound hard/aggressive AT ALL. In fact they are just about the only speaker I've ever heard that can play loud and still sound delicate/beautiful at the same time all hell is breaking loose! Not even my Super 7s can do that.
