Q Acoustics Concept 20 vs Audioengine P4

The Q Acoustics Concept 20 is a relatively good Bookshelf Speaker for people that are willing to spend around $540. The Audioengine P4, by contrast, is quite unremarkable and doesn't stand out in any meaningful way from other products at this price point.

In both cases, however, we recommend that you take look at some other options at the $540 and $270 budget ranges; in all likelihood you'll find some better alternatives.
