+ Buy them for speech and presentations
- Dont buy them for music/entertainment/concerts

They play insanely with EQ so dont forget to buy also the Bose Bose amplifier with the right 402 EQ card. Don't aspect power true these speakers even with subwoovers. BUT... It is amazing how clear they are in echoing locations. For presentation/speech i don't want something else. Meyer Sound and Fohhn are to expansive for me. And you get a better image with bose than other expansive brands. And most people are melting that you say you use a Professional Bose system. But be careful if you talk to a sound engineer, they know better.

Oh yes, the speakers survive all conditions, rain, freezing and burning in the sun. It is very robust.

This ia great sounding unit. It does everything it says on the spec sheet. Dont expect real bass it doesnt deliver it - its not meant to. Coupled with a good amp for their size and weight these units are remarkable for speech and acoustic music. They can go really loud and will project over a large wide area. I also use them regularly for sidefill foldback on worship music and the sound pleasing to the performers and levels before feedback are really good. I have AB'd them for customers agaist several other speakers of a comparable size for church installs and they almost always win easily.
