Bowers & Wilkins T7 altoparlante Bluetooth
The way the unit prevents distortion at high levels, by reducing bass output, is clever, but makes it a little underwhelming at higher volume output. At these levels, which are very loud for a small unit, can sound too tinny and a little uncomfortable for the ears.
The best range in my view is mid level where the bass is more noticeable (probably still a little less than you'd want) and the general clarity is at its best.
I have not heard other comparable models, i.e., Bose Soundlink and B&O A2, but I would recommend you listen to this in the flesh before purchasing. Remember, do not try and compare to a fixed unit, as you will be disappointed. If you want the flexibility to move it easily from room to room, or have outside for a small garden party, it is ideal. Life span of the battery is also remarkable.
In terms of space filling, it will be easily loud enough for a medium size room.
