I bought these for wide angle speech coverage and to supplement a pair of Alto Blacks in bigger rooms. For those purposes they have been exactly what I was after. The vocals sound great on the Bose but when combined with Alto Blacks, the Altos fill in the high end and warm up the low end as well. If you like the L1 series, you'll love these. If you don't like the L1 series, you still will probably like these. They are probably the best sounding pro speaker Bose has created to date. When I said the low end is solid, that is without the subs. I didn't buy those. The Alto's and my Yamaha DSR115 really have not needed them. They are plastic enclosures, but those feel solid. The grill mounting is a bit flimsy though and the controls don't feel like a $1000+ speaker. Now for my issues, by far the biggest one is the input clipping before the amplifier hits limit. The internal limiter seems slow to engage anyway but by the time it does, you are audibly distorted. With there being no real high frequency drivers though, I expect your risk of blowing anything is low. During my brief testing, I did not have any issues with that but I know I'm not able to take full advantage of the amps in them. As I mentioned earlier, the grill attachement is not stellar. Just folded grating that has already gotten caught twice on things and I had to push it back in. The handles on the back are convenient as well. So, if you are buying one pair of speakers and don't need the wide coverage, you can get a good but more for less but if you are using more than one pair of speakers like I frequently do just to have more even coverage without making some guests deaf, pair these up with a conventional speaker and you will really be pleased. They combine perfectly with the Alto Black but I'm sure they would with many others as well. I like them by themselves, but love them combined with something else that can bring a little more crispness to the high end.
