This is a very cool portable sound system. Is it going to satisfy an Audiophile? No. But for casual parties it’s fantastic. Really it’s the battery feature that makes it so useable in areas where there is not AC power.
There is an app available that gives you EQ control and that is quite helpful. Make sure you get the app. Search for “Ion Block Rocker”. In addition to EQ, the app gives you 24 sound effects you can inject into the sound.
Features a 3″ tweeter and 8″ ported woofer. 50W peak power. “Peak Power” is kind of a bogus way of reporting power of an amplifier. No RMS power is mentioned so I have no idea what the real power output is of this. It’s not a lot but for smaller parties and general listening it provides a good amount of volume although there is audible distortion and unfortunately no THD distortion or any other metrics are provided.
AM/FM/Aux with 6 station presets for AM and 6 station presets for FM. A Telescoping handle and wheels on the Block Rocker make it really easy to transport. The Block Rocker also has handle grabs on each side. Plastic corner protectors and a metal speaker grill make this a very versatile performer. It even comes with a 1/4″ Microphone. Although the microphone is pretty cheesy, it is better than no microphone and can easily be upgraded to a higher quality mic if need be.
The bluetooth was easy to pair to my Smartphone and laptop. It also has NFC if your device supports NFC pairing.
Now the biggest thing for me is that this is not only AC powered, but has an internal battery giving a claimed 72 hours playback time. In reality it’s less than that but still the battery life is pretty amazing.
This also has a “Link” capability to connect a second compatible Block Rocker speaker as well as two 5V-1A USB outputs.
I purchased this 6/24/2015 from Costco for $119 during a $30 Instant Rebate Promotion.
