I like most is that their small footprint, amazing sound quality for their size.
I use them mostly on the conference, as it is discreet and classes.

Turning to the principal, ie the sound is pretty good. Able to go down despite the size of HP pokey (12 by 5.7 cm in diameter). They are quite (very) guidelines place is therefore a necessary prerequisite. As a sound engineer would say that I learned a lot "Do not ask a dog puts his shit," the picture is quite trivial but at least it has the merit of being clear.

It is given to use the line array concept. Indeed, the weakening would be only 3 dB per doubling distance. I have not had a chance to check so I trust. But I always pay close attention to business case. I know my side is a little paranoid.

Go, finally I put 10 ... Parcequ'elles worth it.
