JBL Boombox 4: $549.95 Amazon Bhphotovideo eBay
Pros: Pretty insane output capability for the size.
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
