Super sound, but low volume

I can only agree with some of the other reviewers. The sound of this unit is beautiful. It provides good midtones and heights and a very good bass that really good comes into play when you hear relevant music, in a lot of bass found. Absolutely amazing, I also think that from the smaller tube sound really come out clearly perceptible air currents with every bass drum beat.

The sound gave me from the first second immediately liked it very much, so I wanted to enjoy it equally loud .... but unfortunately exactly pushes this device very quickly reaches its limits. When the unit is on full volume and my smartphone is also at full volume, comes with me inevitably the thought: What? That's it? I was looking for a loudness button or the like, but unfortunately was the whole device nothing to find.

When this unit size larger volume would have been possible clearly. I own numerous small portable speaker that can produce a similar volume as this many times larger device.

Thus, I have sent this unit with a heavy heart back.
Now I'm curious, can whether the other BoomBlaster JVC sound similar good and thereby achieve a higher volume ...
