Bought 2 years ago, used just about every day – works fine. Don’t expect eardrum shattering volume. I bought this in March 2016, and finally got around to reviewing it.So it has been nearly 2 years now (Feb 2018), and I have this little guy driving a couple of bookshelf speakers, driven by my iPhone 3GS (yes, you read that right..3GS from 2009), streaming with Tune In. I only use the 3GS for Tune In. I have a benchtop 12V power supply supplying power to both the amp and a 12V to USB for the phone.Details: I checked the frequency response of this little PA with a PC…
Five Stars
Will produce clean strong bass if Passive crossover is used …
