Got a set of Audio Engine HD6 non-amplified-version speakers on Drop.com.
Fantastic sound for the size.
I wish they made a similar center channel and a quality sub.
They mainly focus on Bluetooth Wireless speakers and no center channel at all.
The sub is only average.
So much potential lost.

We are huge fans of Sonos, we have the sound bar, 2 speakers on stands and the sub. Great all round sound and a solid system. It's pricey, but worth the bucks.
