CONS: Bass boost adjust is somewhat muddy. No treble adjust. These can be adjusted at the source unless you're using these with a TT. Needs a subwoofer line-out. Controls are on the back, so is input select with no forward facing indicator. Speaker wire connection between the L/R speakers is super thin. PROS: Easy bluetooth connection. Controls on the back, although inconvenient, are smooth, have a good 'feel' to them. Input select is simple enough, albeit on the back. Sound is better than I expected and they play loudly enough without notable distortion (source depending). More articulate than I would have expected. All In all, a good budget set of speakers for small to medium rooms. Not what I'd call high fidelity but good for casual listening. It's nice that you can switch between multiple sources without disconnecting anything. At this price point I would not expect a built-in phono preamp but a sub-out wouldn't be that difficult to implement.
