  • RockVille Bluamp 21 great value.
Color: Black
Great little unit for the money. Fast shipping. Works perfectly as advertised. This little unit has a lot of bass.Using it with 6ohm speakers sounds really good. Bluetooth works perfectly with pretty good range.

  • The Right Choice!!
Color: Silver
I have this hooked up to a small Episode ev-06 sub-woofer and two bookshelf sonys. The sound that this is producing is incredible and powerful!! The bluetooth connected easily as well. I have to give this 5 stars all the way!!

  • Works great
Color: Black
The media could not be loaded. Powers two 4ohm speakers & does the job well! The knobs are a kind of okay feeling but expected for the price. Bluetooth is great on this. Overall really like for my setup.

  • BT rox!!! Nice form factor.
Color: Black
Great size and easy set up. Note: treble control only. Other knob is for a sub woofer. Patched/hacked into apple pro speakers.

  • It’s loud, easy use, but auto-reconnection/pairing is weak.
Color: Silver
I like it. I’ve tried Fosi, Mii Audio, and Douk Audio amplifiers. Only this BluAmp can power a passive subwoofer, of the four small amps. It can power a subwoofer with 50 watts, @ 4 ohms, not sure about 8 ohms. My speakers are 4 ohms, and 6 ohms.

  • Great power from sub output
Color: Silver
The media could not be loaded. I mainly bought this for its passive sub output. I have to desktop speakers hooked up to left and right channel. This video wasnt even full power on the sub. Close but not all the way. Definitely makes is rated power! 70 watts rms to the sub at 4ohms is not bad at all and these lowerer power 8s love this amp ... show more

  • One sick little amp!
Color: Silver
This amp is outstanding! It gets much louder than I expected - truly impressed by the design and sound quality. Was not expecting the tactile/haptic feel of the knobs (they feel like stepper motors). Love it
