It sounds amazing.
I've had JBLs in one form or another since 1970, including the L100 pair I bought on lay-away while working my way through college. I still have everything from that first acquisition, right down to the sales slip. But more on topic...
My first full JBL surround system was L7s for front L&R, L3 for center, L7s for SR and SL, and L5s for RR and LR. The L3 for center was primarily because it had to be shorter than my screen placement. Because it's possible to actively bi-amp an L7 due to its excellent crossover design, the side L7's 12" woofers served as subs. Yes, it seems a little wacky now, but it was an awesome system that could crank forever.
I could invite over friends who were showing off their HTIB, or a Bose system, or their favorite mongrel mix of speakers, and I wouldn't have to say anything. The JBL L Series spoke for itself. When it spoke too loudly, my neighbors would speak to me, if you know what I mean.
Also, I had a whole rack full of Soundcraftsmen S800 amps that were indestructible under any load. When I didn't need them in the system, I'd take a couple to the garage so I could use them to arc weld the frame and brackets on my truck.
(That's a joke, folks. Don't get excited!)
Love the L7! It's a great speaker.
