Review on Micca COVO-S Renewed Compact 2-Way Bookshelf Speakers - Pair by Harish Soto

If you're looking for a very small set of passive speakers that don't sound like small speakers, read on. These speakers sound good but not great. In terms of size and price, there's not much I can compare or do better. They look like imitators of large bookshelf speakers. Apart from that, here is my opinion. If you have a Class D amp and can hear oddities, these speakers can tame a bit. Most inexpensive Class D amps have a heavy bass that seems to add more sustain to make the bass notes sound fuller. In addition, very high tones appear hard and harsh. These speakers are not very efficient and require more power to drive them. A 20-watt Class-D should be able to drive them, but a 50-watt is desirable to avoid excessive distortion and clipping at high volumes. Because these speakers aren't very efficient and can't reproduce very deep bass, it helps to muffle the sustain notes of the Class D artificial bass and bring the bass back into definition. The tweeter isn't aggressive and this tames the sharp and harsh high notes of Class D. After breaking in these speakers they sound good with my Class D amp. But they sound a bit lacking when run with my Class A amp /B can be operated. Yes, they're good for small rooms in combination with Class D amplifiers. The bass is there, but not strong (hey, these are very small speakers). The tweeters work a lot, but are not tuned for very high tones. They appear to be tuned for the upper mids and mid highs. I think this setting is intentional so they don't sound like small speakers. Adjusting the tweeter to what most would expect it drowns out the small bass/midrange and now sounds like a bunch of small speakers again. There is so much you can do with these small sizes. Update 11/4 A few days later, here are my findings: REMOVE THE FRONT GRILLE! Sounds much better now, you can hear the tweeter. Fairly acoustic high frequencies, not harsh, sound pretty good. Class D amplifier recommendations best used with amplifiers that have high and low frequency controls. Turn down the bass a little and crank up the treble a little. As a result, the sound is greatly opened up and tidied up. Just adjust a little and as little as needed. You will know when you hear this change. Avoid using with other speakers at the same time. The subwoofer is fine as it may not be affected by this tone control setting. Class A/B amplifiers are recommended, avoid using them as these amplifiers tend to reproduce more sound detail and these speakers cannot handle that in busy, loud passages. This overloads the speaker and distorts the sound, obscuring background detail. Avoid using with other top speakers as the tone setting may adversely affect the top speakers. These speakers should only be compared to full range/single range speakers as this will be a good option. It cannot be compared to good, larger bookshelf speakers. Yes = Good TV/Video sound in a very small package, Class D amp with tone controls and grille removed. You have to make a choice = listen to music (anything but background listening), be able to afford a larger speaker with better than Class D amps.
