This is an old thread, but I wanted to add that I just set up my pair of JBL L110s with a pair of L150's in a large room. All four are being driven by a Marantz 2325 receiver, rated at 125 wpc for two speakers. So it is running about 60-65 watts per channel playing all four speakers. The L150s are rated at 200 or 300 watts, I forget which. But they did well at 125 clean watts from the Marantz 2325. The only problem is that in a large room they were somewhat directional. You had to sit in front of them to get the channel separation. The four speakers together in a room about 25 x 35+, sound great. So glad I added the L110's to the set up.
It seems like I read somewhere a while back that the L110 was supposed to be the residential version of the L100 studio monitor. But I would need to confirm that.
I bought my pair of L110 speakers on eBay a couple of years ago. Think I paid $250-300 for them. The cross over and drivers seem fine. The cabinets are not chipped or broken, but they need to be refinished. Plan to start that next week. Now that they are in the living room, they need to look as good as they sound.
In summary, if you find a pair of L110's for under $300 in good shape, buy them. And if you are looking for a complimentary set of speakers for a larger room, I think you will be pleased with L110's. They are a great compliment to the larger L150 speakers, which have a 12" bass and 12" passive woofer.
