NOTE: The COVO-S is not self-powered, and requires an amplifier and speaker wire (not included) to play music. The COVO-S compact speaker system is another landmark product form Micca that delivers great sound in a small package. Drawing from the same classic yet distinctively design as Micca's popular MB series speakers, the COVO-S looks great and is easy to place in wide variety of room decors. Its exceptionally rich sound belies its diminutive size and makes it a great selection for use in a small to medium sized listening areas such as an office. The COVO-S is shielded.Superior Sound Through Superior Engineering Built using patented concentric driver design, the COVO-S's audio performance results from a balanced application of sophisticated drivers, enclosure tuning, and crossover construction. The speaker driver used is a 3-inch wool paper cone woofer with an inset mounted 0.75 PEI dome tweeter. By sharing a common acoustical center point, the concentric woofer and tweeter design maintains coherency through the crossover transition region. The unique curve of the woofer cone serves as a horn waveguide for the tweeter, resulting in improved off-axis dispersion characteristics. The COVO-S employs a ported enclosure design, generating modest bass output for a warm sound signature. A 6dB/octave crossover makes for a smooth transition between the woofer and the tweeter. Rounding out the package are full size 5-way speaker wire binding posts and removable grills. Compact and Affordable Hearing is believing. Discover how good a pair of affordable compact speaker can be by trying them risk free in your home. Due to the COVO-S's small size, they work best when used in a small to medium sized listening area. Place them along a wall or near a corner of the room for better bass output. If you are not absolutely delighted with the COVO-S's performance, simply return them for a refund.

The COVO-S is a compact speaker with a 3" coaxial driver, the woofer is a wool cone with a 20mm voice coil and the tweeter is a 13mm (approx) plastic dome unit mounted in the space where the dust cap would normally go. It has received rave reviews from many people here and on Youtube, but Noaudiophile has the most accurate review, search it out and read it. One of the speakers was rattling when I got it, turned out the inductor had detached itself from the terminal cup (it's held with hot glue). A few seconds with a heat gun and it was back in business.
The speaker is finished in black vinyl wrap and the grills come with sturdy metal clips instead of the weak plastic ones you get almost everywhere else. They should be left off when listening, they are very obstructive - this is true for almost all speaker grilles. The rear has a pair of 5-way binding posts, but bananas are the only viable option as there's really no room to turn the posts on wires or spades unless you have dainty hands. A 3/4" port and a 1/4" wall mount nut complete the rear, along with a label. The build quality is modest, the 12mm MDF cabinets have a pretty prominent hollow ringing when you tap them, which is the first sign of trouble.
The driver itself is a custom stamped steel frame unit with a very obstructive rear (another severe sign of trouble) and is mounted on a recessed cutout without rear chamfering, another sign of trouble to come. The top of the driver (when vertical) vents directly into the port, which is a sure recipe for disaster. There is a small amount of damping material, but strangely the top is left out. All speakers have a long dimension mode and need extra damping usually at the top and bottom, or wherever the longest dimension(s) happens to be. All of this creates a perfect storm of mistakes that are apparent even before the speaker is turned on.
I'm using a MOTU M2 for source, the headphone output is hooked up to a AKG K92 and the unbalanced output is connected to a LM1875 gainclone. To be sure there was no upstream problem, the setup is tested with the Usher Mini-Dancer and it has no issues either in quality or output, with accurate correlation between the headphones and multiple pairs of speakers. With the COVO-S, however...
The speakers are terrible. Out of professional courtesy to a colleague, I won't get into too many details but these are unusable. The cabinets have terrible resonances, the treble droops way too early and the top three octaves are simply missing. It seems the designer didn't reference this with anything (not even a decent set of headphones), or was running them on a very bright amplifier - or was responding to demands for bass - and tuned the speaker to produce bass (that it can't actually do). This is a classic case of trying to hit too may targets, and missing all of them.
The speakers are muffled, indistinct and boxy. The tweeter is inaudible. I don't expect them to compete with Ushers or a custom pair with Satori drivers, but I expect a clean midrange and a serviceable frequency response. This has neither, and the bass that it does produce is boomy, indistinct and bloated as the little driver tries to keep up with the unrealistic demands placed on it. Adding some mass damping to the walls helps, but not a lot. Blocking the ports also tunes out some of the bloat, but the poor presentation remains.
There's too much baffle step correction and I suppose they would work if placed in a large room with no boundaries within a few feet, but why would you use a 3" speaker like that? Overcompensation seems to be a common thing now in Chinese speakers. I suppose they think it produces impression of more bass, but it doesn't. It just makes things muddy. To sort this out I tried a variety of placements and supports (on table, in air, soft mounted, hard mounted and on stands), before coming to the conclusion that the speakers are simply unusable in a decent setup for people with ears.
Simple A/B with a pair of half-decent headphones (or any competent speaker paired with a decent amplifier) reveal a plethora of issues. I am not sure what other speakers the folks at Micca have heard, but it can't be very many, or very good ones. I would really recommend them to get some test equipment and measure their work. They don't seem to have got many of their products right. Ignore the glowing comments on Youtube. It's not uncommon for India to receive factory rejects and seconds, and way too many reviews are paid for and bought on the promise of free stuff.
I can't return these as they're already opened and worked on, but I hope this saves someone the heartache of buying something that is simply not worth the money. A cheap car coaxial in a small box will work way better than this, with a bit of EQ.

Now, out of the box, connected to my Micca OriGain amp/DAC (awesome device BTW), they sounded a bit... strange. It's hard to describe it. It's like they were missing a part of mid-range. It made it uncomfortable to listen to. I did a bunch of research and decided to try an equalizer program. I boosted the gain mostly in the middle of the frequency band - and WOW, they sound so much better now!
They don't have a lot of low-end response, so I pair it with a powered Kanto SUB6 subwoofer. I've owned the AudioEngine A5+ (paired with Kanto Yuri sub) and Kanto YU2 (paired with Kanto SUB6 sub) and I've got to say this setup sounds almost as good as my AudioEngine setup, and about as good as my Kanto YU2 setup. Now keep in mind that the speakers cost much much less.
So if you get these speakers, play around with an equalizer a bit and you'll get some great sound out of these.
