it is all metal, including volume wheel and the arch above. And the plastic "gum" on the sides and bottom permits good stability when it is placed. The set is strong and durable (the weight is reassuring)
the volume dial has a very convenient stop and really allows fine tuning of the desired power and fall rapidly if needed.
the sound itself is very good. A good balance between the treble, mid and bass. And no distortion at max.
I tested including barbecue evening and it was really nice: early evening speaker was placed in the middle of the table with quiet music medium volume (background music) and as the sound was broadcast around , no need to push and everyone heard the same volume ...; and in the late evening with the ambiance that rose well, we threw each on the grounds of good sounds that go well, the volume to the max and it really looked good (with enough bass to make you want to move her body. ..!)
in short a very good alternative (or better?) to the EU Boom for cheaper (I bought 95 at its output, against 200 at its output for the EU Boom). And in addition I think she has class. It has had its effect when I put on the table.
shame that Philips does not communicate about this speaker ...
