Long throw poly woofer

Silk 0.75 Inch Tweeter

Advanced Crossover

The stout 4-inch woofer is built on a truncated heavy steel frame and substantial magnet structure. Its long throw design incorporates a coated pressed paper cone with concave dust cap, large radius rubber surround, and vented pole piece.

The tweeter is based on Micca’s popular 0.75-inch silk dome design, using an high efficiency neodymium magnet and a form-cut bezel for tight driver spacing. Translucent mesh fabric over beveled thin frame make up the acoustically transparent grill cover.

The RB42 owes its tonal balance and transparency to a 10-element crossover that uses high grade film capacitors and air core coils for key components. Both the tweeter and woofer circuits have a 18dB/octave slope to enhance power handling, dramatically reduced lobing, and superior off-axis performance.

RB42 Enclosure

Made for Music

Made for Music

Distortion and coloration is effectively reduced through the use of ¾-inch thick MDF panels on all sides of the enclosure, with 100% miter joints for greater bonding contact area. The enclosure is stuffed to specific density with polyfill to eliminate resonance and enhanced enclosure tuning.

The RB42 has a versatile sound signature. On the one hand it is fun, energetic, and inviting to listen to for hours on end, but sit down in the sweet spot for a dedicated session and you’ll be rewarded by its revealing qualities full of dynamic detail.

The bass extension and output is unusually satisfying for such a compact speaker, while its smooth frequency response reproduces music faithfully with engaging tonal balance. The tweeter is level biased just slightly below neutral to reduce listening fatigue without losing a ounce of detail.

    So I got these after Zeos was talking them up real big. I figured they'd be hard to drive and the small bl20c I got to push them wouldn't cut it, but so far I am so impressed.For comparison I have an LG SL7Y soundbar and it's included wireless subwoofer. Of course these don't quite match the bass output of that sub but for less than half the price they stomp that soundbar.They just pump out so much power at such a high quality for the price it's absurd. So far I've tried these with a Metallica vinyl and a bunch of stuff from my phone over Bluetooth to the bl20c and everything just sounds wonderful.Bass performance is powerful and clean. Rumbles my room nicely when needed.Highs are clear and don't get harsh, even with the tendency for my record player to highlight cymbals.These look nice and the front mesh is magnetic and just comes off with a light pull. The vinyl wrap is very tasteful and the wood construction doesn't echo at all and feels very sturdy.Overall I'd say these are an amazing bang for the buck even at regular price, and I can't wait to get a sub to pair them up with and a DAC so I can move the soundbar to another room entirely.Update: Got a Wiim Pro Plus so everything's all hooked up completely and the LG soundbar is now out of my room. I've gotta say, it's been maybe about a month and I'm in love with these speakers. I'm honestly debating on whether or not a sub is even needed for me, as all the EDM hits perfectly and these fill the room so well. Metal and rock kicks don't hit quite as hard, however, so maybe the sub will be an addition in the end, but as it stands, they're really quite capable. I don't think I've ever needed to push them to their limit, either.For reference, these are in a room that's roughly 20'x20' with a little bit of furniture. No room correction or anything like that has been performed, and most of the audio has been YouTube Music streamed via airplay or wi-fi from the pc, so not really anything hi-res except for maybe my records.

    Let me start off by just saying that either the fine folks over at Micca just want as many of us "ordinary" people to be able to enjoy quality sound or they are simply crazy for offering such a fine little speaker at the price they are selling them for. (Oops. Maybe I shouldn't have said that.)

    First of all, a little background: when I ordered the RB42s, I wasn't expecting them to be as good as they really are. In fact, my initial plan was to use them as a step up from the speakers I am currently using for my PC. You see, I have an older Logitch 5.1 speaker system and while it is pretty good (I like having better sound quality, mostly for gaming, but I also listen to quite a bit of music, watch videos, and even watch the occasional movie or TV show) the system (the speakers all plug into the little subwoofer) is beginning to show it's age and has started to occasionally short out (no sound comes out due to some faulty wiring and the amplifier gets warm and shuts the whole system down). So, I ordered the Micca RB42s just to see how they sounded before I took the plunge and bought another pair (for the surround speakers) along with the center channel version of the RB42 (the RB42-C). (Along with finding a suitable subwoofer, either getting a better one for my home theater and using the old one with my PC or just scrounging one up online that wasn't completely terrible).

    Let me tell you, I LOVE THESE TINY SPEAKERS! I was simply amazed at how much sound came out of such a tiny package! And make no mistake, QUALITY sound, at that! And while I do still plan on using a subwoofer, I was surprised at how much bass these little boxes produce! While they might not shake the walls, they still have some respectable (for their size) punch and rumble to them. So, I am comfortable saying that I will definitely not be having any trouble integrating whatever subwoofer I end up using with these speakers. I was afraid that I would have to make the sub crossover frequency go higher in order to fill in an audio "hole" which would make the sub more noticable. Something you definitely don't want you subwoofer to do. Like I said, I'm not going to have to worry about that.

    Now, I haven't pulled off the back to take a look-see at the components/circuits used in the crossover, but the sound alone confirms that what I saw in the pictures is certainly at least close to what's inside. I'm still going to take a look at what's insides of these little beasties (I just can't help myself!), but I'm certain that I won't be disappointed. It just goes to show you what using quality components can do for the resulting sound.

    Speaking of quality, I have to mention that the cabinets are very solid (knocking on them sounds like knocking on a solid block of wood and not a hollow box) and the dark wood venere finish is very subdued without being overstated or "Look at me! Look at me! I'm a speaker over here!" flashy. Very nice, Micca. Very nice.

    I should also point out that these speakers have some physical depth to them, so if you're planning on putting them on a bookshelf, make sure your positioning plan has enough space availabe for them. They are ported in the back and seem to like to be a little ways out from the wall (experiment to find a sound that's nice to your ears). They are 7.9 inches deep, so keep that in mind.

    I also highly recommend driving these speakers with as much power as you can give them (up to their rated wattage, of course). I'm pretty sure they'll sound just fine with less amplifier wattage, but you will be nicely rewarded if you can give them plenty of juice. When I first hooked them up, I happened to be using a vintage Carver TFM-35x amplifier which is rated at 250 watts into 8 ohms, but that's just because I had it sitting on my work table. (I'm currently assembling a veritable Justice League of vintage amplifiers that I am going to refurbish and use in my home theater.) Once I'm ready to put these speakers in position, I plan on using a 100 watt amplifier. However...Now that I've finally heard these speakers, I'm happy to say that I'm going to be moving them (along with a RB42-C center channel speaker which I now have on order and am VERY excited to hear!) into the surround position of my 7.1 home theater system! So, now my current home theater surround speakers are going to be moving to my PC speaker system instead. THAT'S just how much I REALLY LOVE these speakers! And they are MUCH smaller than my current surround speakers, so it's a win all around!

    OK, I'll quit talking now. Just know that you'll be making a good decision to purchase these speakers for whatever your application is. In my travels around the Internet looking for information about these speakers, I saw people mention that they sometimes go out of stock, so get them while they're hot! You will definitely NOT be disappointed!

    UPDATE: I spent a lot of time searching for a suitable stand for these speakers. Let me save you a lot of trouble by pointing you toward Kanto SP32PL 32" Bookshelf Speaker Stands. They are a good compromise between quality and cost. I'll let you know how they work out with the MB42s.
