Very affordable, surprisingly well performing small monitors. Smooth, detailed and balanced mids and highs. Not suitable for really extremely bass boosted content. First - they don't play audible deep bass, Second - if pushing volume above 50% with that content, it starts easily get overwhelmed and distort. But that's a physical limitations! In other cases their power or volume loud enough...
Pros:
Tiny composite woofer - fast, clean, crystal clear midrange
Smooth, sharp, well present treble
Decent midbass
Volume knob on front
Bassreflex at front baffle
Detachable power cord
Back power switch
Selfpowered
Low price
Cables included (power+L to R speaker est.2m/6,5feet long, you can replace with any length you need)
Exist variant with disco lights on top
Cons:
Lack of deep bass
No subwoofer output unfortunately (can be added only sub with in/out stereo audio connectors - passthrough)
No digital in
No wireless
No bass/treble adjustment (irrelevant - could be get distortion even worse)
Sine wave frequency response in my medium size room, volume 35%:
Audible start from 40Hz, but up to 60Hz weak (-25 to -15dB) or distorted!
60-80Hz (-10dB)
80-90Hz (steep roll on)
90-20(k)Hz ±5dB linear response
Note: No near field, room acoustic effect.
