After 2 years of the 3 of us, I, my nylon string guitar and Acus Allaround 4 are living together, here is what I can say.
I think the best future is the accurate, natural sound it produces.
Its solid construction sits firmly on a perfectly even floor and emanates warm, crisp sound tones, often indistinguishable from the original even to the trained ear.
Playing arpeggios next to it, halfway up the volume, it is difficult to say if I'm hearing the speaker or my instrument.
Power is indeed limited, still louder than most players and this contributes to its high sensitivity, 0 operational noise and overall realism.
It keeps its sound quality all the way up the volume with no effect or tone added.
Effect and tone shift knobs have quite dramatic effects for its character, I'd want them more subtle but still ok since they are sensitive and accurate enough.
I love the clickless on-off function, the small storage for bits and pieces and the magnetic lid.
Screws and hinges are kept to a minimum in size and number, are all of the best quality and the wood finish is immaculate.
As others said before, the Bluetooth connection with the included gratis unit is weak, only good enough for a smartphone sitting on top of the lid or in the storage under it.
Once you are ok with that, close the lid, or not and there you have the perfect Bluetooth speaker that can fill a rather large room with any type of music you choose way above conversation levels.
The power bank future is a welcome option and It seems the mini jack input only functions with TRS connectors.
A true complaint, the grooves on the lid are too small for braided cables and there is no convenient way of carrying it one-handed.
Overall I feel very happy with this product, I believe I got myself a timeless value guitar speaker that expands my creativity and performance levels
