These speakers are tough to review for me. On the one hand, as speakers to listen to music on, by themselves, these fall far short of offering something compelling. As a feat of engineering and getting all they could for $40 in a tiny speaker, it is fairly remarkable. So, starting at the conclusion, the Micca Covo-S is suitable only in an extremely compromised position, when you need both a cheap and a small speaker. They could work as a soundbar alternative or in a cheap surround sound setup.
One interesting thing about these speakers, is, in order to make them small, the tweeter is physically inside the woofer. That’s pretty neat by me.
When I listen to music, the problems with these speakers are quickly evident. The low end is a complete mess and non-existent. The very high end is surprisingly missing. The middle frequencies are actually pretty good. This makes them completely unacceptable for listening to music. As far as playing surround sound tracks, they will do just fine at whizzing bullets and spaceships. I also listened to some television programming, and they handled dialog and such just fine.
So, when would I recommend the Micca COVO-S? If you can’t afford a better small speaker, and are using them in an exclusively living room setting. That is to say, I can only recommend them in particular situations and then with reservation.
As of 6/23/2015, I’ve updated my measurement techniques. This review has been updated to include new, better measurements, which will be explained in an upcoming post.
Going to the measurements, we can see these speakers only work acceptably between 150Hz and 7000Hz. That’s missing lots of the spectrum. It does do a better job in that region than the Dayton B652 does, which is the other speaker at the same price point worth discussing. It is also worth noting there is a large amount of distortion with these speakers which I was able to measure, as much as 10 times as much as other speakers I’ve been reviewing.
