Not to discourage you anyway, but pls check EBAY and you will find loads of JBL L series refurbished speakers resold by Harmanaudio. They may have manufacturing issues with this series. FYI, I am a JBL owner (E30 bookshelf) and not too happy about JBL.
I have purchased several speakers from HarmonAudio, including a pair of
L880's, and must say that I have been very happy, especially for the $434 including shipping that I paid for them. Only once out of 7-8 purchases was I not happy with the remanufactured product. HarmanAudio's customer service dept. took care of it right away and paid for return shipping, and sent out a new unit. All of their remanufactured products carry a full, new product warranty. In fact, most of thier products look brand new, they may just be an overstock. I would have no problem at all in purchasing from HarmanAudio in the future.
The L880's, while having only 6" woofers, are still a fairly good sized tower. I was pleasantly surprised at the amount of bass that comes out of these speakers, probably due to the cabinet construction. I still recommend using a subwoofer for even lower extension.
I would recommend the LC2 over the LC1 if you have a place to put it. Unfortunately, for me the LC1 worked better in my setup. I also couldn't pass up the $99.95 pricetag on clearance at Frys. I really like the LC1, but when I listened to the LC2 it seemed to have better midrange clarity. This would make sense, because the LC1 is a 3 way speaker, but it has no true midrange, only a woofer, a tweeter, and an ultra high tweeter. The same goes for the L820 vs the L830, with the L820 being the 4 way speaker with a true midrange.
Overall, I would definitely recommend the Studio L series if purchased at a substantial discount like I did. I feel that for under $550 for the front 3 speakers it is quite a bargain. If you do not want to buy remanufactured, there are many other online deals still worth checking out for the Studio L's. At full price there are quite a few other brands that I would look into first.
