    200 Watt Bi-Amped Bluetooth Bookshelf Speakers with USB

    Bluetooth Bookshelf Speakers

    Tons of horsepower, great looks, and flexible connectivity options make these speakers the definitive desktop speaker system. Featuring a separate 50-watt RMS amplifier for each of the four drivers, these speakers produce deep and solid bass, without the need for a separate subwoofer, plus clear, clean, and articulate mids and highs. The USB input option makes them the perfect audio companion for a desktop computer gaming system. The dual RCA line inputs allow you to connect to up to two line level audio devices and the Bluetooth® radio allows for easy streaming from your mobile device. An infrared remote control is included so you can adjust the volume and switch inputs without leaving the comfort of your couch.

    Sound Quality: Life is too short for speakers that don't sound great! We believe that the whole point of listening to music is to hear it as the artist intended. Our engineers and audio experts have spent countless hours listening to and comparing various speakers and headphones until we were satisfied we had found models that fit our demanding standards.

    Connectivity: We want you to use these amazing speakers with everything, so we packed them with connectivity options. Use a USB cable to connect to your Windows® or Mac® PC or use the Bluetooth® feature to wirelessly stream music from your phone. The dual RCA line inputs feature a high-level input for connecting to line level audio components, such as CD and DVD players, and a low-level input for connecting to the headphone output of an mp3 player or other mobile device.

    Power: Oh yeah, baby! You say you want power, well these speakers have power and then some. Each of the four drivers is powered by a separate 50-watt RMS amplifier, for a total of 200 watts RMS! Ordinary powered speakers, with only a single amp per channel, suffer when one driver wants more than its share of power, causing the other to be underpowered. This can cause distortion or even speaker damage. By using a separate amp for each driver, we ensure that each tweeter and each woofer gets all the power it needs.



    Streaming videos, podcasts, and music has never sounded better!

    Can I add a subwoofer without an amp?
    New User U on Jan 20, 2017
    BEST ANSWER: If you have a self-powered subwoofer with line inputs and a built in crossover, you can configure the inputs to pass through the crossover in the subwoofer. Thus the new input to the speakers is minus the bass frequencies which are then play by the subwoofer. Should work..
    Would these speakers work with an Amazon Dot?
    A shopper on Nov 23, 2016
    BEST ANSWER: Yes. These speakers would work with a 3.5mm to dual RCA cord to connect to the Amazon Dots 3.5mm out connection.
    Does this speaker have standby/auto on? I would like to use with Chromecast Audio
    A shopper on Nov 21, 2016
    BEST ANSWER: No auto standby, needs a manual power up each time
    how long is the slave speaker cable / how far apart can the speakers be separated?
    New User U on Jun 16, 2017
    BEST ANSWER: I own these...the cable between the speakers is about 12 feet.
    If using the line-level inputs only (no bluetooth connection) is it possible to control the volume using the remote? My concern is that line level signals are of a fixed level and do not rise or fall with the speaker volume-level of the source amplifier. Therefore it is essential that volume level be controlled at the speakers - not just if using bluetooth, but for a line-level source as well. Is this the case?
    A shopper on Mar 16, 2017
    BEST ANSWER: Yes - You can adjust the volume with the remote. All the inputs are adjustable. You are changing the volume at the amplifier not the inputs.
    Since these are individually amped already could they be paired with the "50W Stereo Tube Amp with Bluetooth and 5-inch Select Speakers" (Product # 16155)?

    50W Stereo Tube Amp with Bluetooth and 5-inch Select Speakers
    50W Stereo Tube Amp with Bluetooth and 5-inch Select Speakers
    BEST ANSWER: There are no speaker level inputs on these speakers so you would have to use the pre-level output from the tube amp. I would look at the 13706 or 16074 speakers instead.
    What is the make and model of the DAC? Thanks.
    A shopper on Jun 20, 2017
    BEST ANSWER: Monoprice Product # 6884
    Are these speakers 4.0 Bluetooth connection or 2.0?
    A shopper on Mar 26, 2017
    BEST ANSWER: The spec's say it's Bluetooth 3.0. I don't see any spec though that it's using the "HS." capability of 3.0. Note that it works fine with the iphones that are Bluetooth 4.0. I don't think the LE features of 4.0 are applicable to this device.
    power requirement of this set?
    A shopper on Dec 13, 2016
    BEST ANSWER: The description clearly talks about the built in amplifier
    Why does it have 4 separate amplifier circuits? Why is the tweeter powered by an amp with the same output power capacity as the sub?
    A shopper on Jul 12, 2017
    What is the length of the slave speaker cable?

    Good living room speakers with a caveat
    I wish to mention outright that Monoprice provided a sample for review, but that is the extent to their participation in this review. All thoughts and findings are mine alone. Secondly, please refer to this album of photographs (http://imgur.com/a/pgrou) which will be used in the bulk of the review itself.



    Packaging: This is one thing I am very particular about when it comes to sound equipment, and unintentionally this very item got tested for it even before it got delivered. US TSA and the courier service decided to randomly pick this package for inspection and they did not handle it gently (pictures 1-3 in the album). I would like to see Monoprice add a "Fragile" sticker to the packaging here if possible but despite the rough handling the sample arrived in near perfect conditions. Two pieces of thick, hard styrofoam keep the contents in check (pictures 4, 5) and the only "damage" was a scratch on the styrofoam itself.



    Accessories: Aside from the bookshelf style speakers themselves which we will get to soon, you also get accessories packaged in recycled cardboard (pictures 6, 7). This box contains a user manual (picture 8), a power brick adapter (pictures 9-12) which takes as input 110-240 V mains making it globally compatible and provides a 24 V, 4.17 A output (100 W) to the speakers. This power adapter leaves very little headroom to account for any issues as the amps rated at 200 W total follow the general 2x speaker power rating for clean, undistorted rating. Thus not only is there not much headroom in the amp power rating but also the power adapter will end up running at near 100% rating. Keep in mind that these ratings are with the volume at full with the speakers in wired mode. Aside from the power brick, you get a slave speaker cable to connect the slave unit to the primary unit and a power cord to connect the power brick to the mains (pictures 13-18), both of which are rated at 18 AWG. Again, this is a cost cutting measure as 16 AWG or better are generally preferred but it is not a major issue for bookshelf speakers which are meant to be close to each other. Also provided is a USB type A female to type B male adapter cable (picture 19), with the primary speaker unit having a female type B port on it. This allows you to connect a computer to the speakers, and this is also where the built-in DAC comes into play. If you have a HTPC, then this would be a nice way to connect the speakers- especially if your motherboard does not have dedicated sound channel outputs. Speaking of, you also get 2 sets of RCA input cables (pictures 20, 21) to cater to the strong signal and weak signal RCA input jacks on the primary unit. Finally, there is an IR remote (pictures 22-24) to control the speakers. It takes a CR2025 button type battery which comes pre-installed in retail units. This review unit was air shipped and as such did not have it pre-installed. All the accessories were confirmed to work as intended in the testing period of 10 days.



    Speakers: The two units come with a thin, soft foam sheet covering each unit on all sides (picture 25) and removing it you see the units are all black, large and rugged (picture 26). Each unit comes in at 30 x 20 x 20 cm (although the primary unit extends backwards another 4-5 cm) and weigh ~13 kg (29 lbs) total. There is not a lot of weight disparity between the two units and they do quite similar aside from the back (pictures 27-35). The primary unit has the power and connectivity options on the back, along with a decently sized anodized aluminum heatsink as a passive cooling solution for the electronics. As such, you need to make sure the primary unit at the very least is in a ventilated area and not cramped/confined. The user manual recommends allowing for at least 12" of space around it and I agree with this assessment. Without going into a lot of detail on the speakers themselves as the user manual does a decent job, you have wireless (bluetooth) and wired (RCA, USB) connectivity options. The power and reset buttons are on the back which is a minor nuisance but thankfully the remote control can handle powering the speakers on and off. Removing the front speaker grills gives you a better look at the woofer (6.5") and tweeter (1") on each unit. Also on the front of the primary unit is a status LED which is a good visual indicator of the unit in action, with the various LED functions explained further in the user manual. At the bottom right on the front of the primary unit is the IR receiver for the remote so make sure it is not obstructed either. There are no "feet" on the units which does mean they are prone to get scratched easily. The units themselves are stained wood, as seen in pictures 36-40, and build quality is not the greatest here. The glue used to hold the woofer and tweeter in place is messily applied, and some better space management could have been done to reduce the overall dimensions.



    Functionality: While I will do an add-on review soon with quantitative test results for the speakers, I wanted to provide my thoughts on the speakers as they are now. In wired mode, be it RCA (I used the strong signal jack) or USB, they sound really good in an open room with walls 10' away in the other directions. The speaker jack cable is long enough so you can have the two units on either side of a large 50" TV as well and connect it to your home media (disc players, HTPC or the TV itself). Bluetooth mode means you can use a smartphone and apps such as Pandora easily but keep in mind that audio fidelity takes an appreciable hit here. The rated specs are for the unit in wired mode only as expected, and there is a good 10' of straight distance between the source and the primary unit in wireless mode before things get pretty bad even with the volume at half way. The units are a bit too large to be used as desktop speakers on desks in most cases, but they do excellent sound options for a small den or office as well. The sound signature seems to be mostly flat but there is some adjustment in the bass/treble range to offer enough for most people. Indeed, I tried out a variety of different audio sources and came out impressed. Let's be clear here- this is NOT a set of audiophile monitors, and from initial testing it is not really very frequency neutral either. If you are looking for studio grade monitors then look elsewhere, I am told Monoprice themselves have other suitable offerings here.



    Conclusion (for now): The speaker set is priced at $230 in the USA and a lot of this is to do with the various connectivity options included. If bluetooth is not something you plan on using, then realize that you are paying extra for no reason. But if all these options sound good, and the caveats mentioned above are not deal breaking then I would recommend this unit. It is not perfect by any means, but offers enough to distinguish itself in the crowded market of bookself speakers.

    PROS: Well priced, good connectivity options, well built, near flat frequency response in the advertised 30 Hz -20 KHz range, 4 drivers in total with an in-built DAC and a 200W (net) Amp

    CONS: Build quality could be better, unsuited for most desktop gaming rigs, bluetooth mode results in a big fidelity loss, DAC does not cover the full range of the speaker's frequency output

    Awesome Versatile Speakers
    Now let me start off I am no audiophile at all. I do appreciate good sound but I know good sound when I hear it. First let’s start off with the looks of these speakers. They’re not the flashiest speakers you’ll ever see but that’s not important. They look nice enough to feel at home with a decent audio setup. All the accessories that come in the box give you the option to either use them as dedicated Bluetooth speakers as their name implies or plug them in to an audio interface and use them as speakers for your computer or any other type of audio set up you want. The set up for the Bluetooth was pretty painless. Connect the speakers, press Bluetooth button and pair with the device of your choosing. The added remote is nice for controlling the speakers from a distance if you’re not using your phone to control the Bluetooth speakers. But the important thing about these speakers are how they sound. I used a plethora of different kinds of music to test these speakers, from rap and rock to country to classical and these speakers did not disappoint. The rap music was clear with enough bass to please even the most bass heavy Beats user. The rock music was loud but no distortion at all. Basically any type of music you want to play through these speakers will sound great. The options these speakers give you are kind of limited. You can raise and lower the bass and treble. So EQ setting are available but for me that is of minor concern. I’ve listened to lots of speakers in my time and I must say that these speakers are just awesome. I love the versatility that these speakers give you. Want Bluetooth speakers? Yep got’em. Want to connect them to your audio set up? Yup you can do that do. If you want great sounding speakers with good versatility then these are the speakers that are for you.



    These speakers were provided by Monoprice for review purposes.

    Mine Turn Off Early too
    The speakers live up to my expectations in terms of sound quality, they are very nice, especially as I paid 160 during the black friday week 1 sale. The issue is that the speakers seem to lose connection to my Mac Mini after any brief pause in sound output, and I have to reach for the remote to power off and on the speakers to reconnect the sound to my mac mini. its rather bizarre. Are mine defective?

    PROS: Sound quality, price

    CONS: power/connection turn off issue.

    Bluetooth Bookshelf Speakers
    Does what I expected and were received in good shape.

    PROS: Decent sounding with an excellent array of possible inputs. I didn't expect the sound to equal studio quality monitors, with which I have experience, but wanted decent sound. I use them in my garage while I am working there and it does the job to my satisfaction.

    CONS: I would have liked a little better tone adjustment, like a graphic equalizer. Doesn't remember the last input used so need to change input type after power has been removed. A little pricey but cost was acceptable to me.

    Turn off early
    Great speakers. I am very pleased with the sound from my computer.

    I am using the speakers to help with studying. They turn off very quickly. I have to use the remote to turn them back on every few minutes.


    PROS: Pros: sound, bass, midrange, tweeter. volume

    iPhone bluetooth: great!

    CONS: Turns off quickly. Wired better than bluetooth from computer.

    bluetooth speakers
    Great speakers: great sound when wired.
    But, bluetooth is a problem. Works well with my iphone, but not well with my windows 10 computer. Anyone else have that problem? It pairs, but either one of the speakers does not work or they both don't work. Called Monoprice, but they found that the documentation covered Windows Vista, XP, and 7 but not 10. Hopefully, there will be an update.

    PROS: great sound

    CONS: bluetooth problems with windows 10

    Great speakers for the price
    I had them on my desk playing side to side with an audioengine A5+ for 2 days. I could not notice any difference whatsoever. I had 5 friends coming over just to listen on a blind test comparing the two of them. No one could perceive a difference. Actually I feel that the bass and the very high end treble on the monoprice do have a stronger presence. With the audioengine a5+ selling for $460 ( Bluetooth), this pair of speakers is a steal.
    I also tested the $300 Thonet & Vander (Kugel) which I think is a bit better than this Monoprice. Not a knock out. Just a bit better but at $100 more.

    PROS: Remote Control, Bluetooth. DAC

    CONS: Big footprint, heavy.

    HTPC and Home Theater Speaker Solution
    I would like to thank Monoprice for sending me this item for review purposes which will not affect the opinion or experience I share here.



    First of all these are perfect for a HTPC setup or to use along with a Home Theater set up to listen to your media, watch movies and console gaming. Make sure you have plenty of room when setting these up because they are not small and weigh 28.5 lbs, so these are not to be used on a small desk or TV cabinet. They have a very clear sound and can get to a decent high volume level without losing clarity, however the options to adjust bass and treble are a bit limited. For what I can tell you may be able to adjust both approximately 3 to four levels up or down.

    I tested them using the USB connection with my HTPC set up and Bluetooth option with my mobile devices. When connecting to PC it was recognized immediately (plug and play like) and I was able to use without any problems, just remember to select them under playback devices. When using Bluetooth select Bluetooth mode on your (speakers) remote control and a blue light will begin blinking on left speaker waiting for a device to pair up with. On mobile device look for MP Bookshelf and pair, very simple. Also note that the media option for play, forward and rewind is available through Bluetooth option as well.

    I did not get to test the RCA inputs since I do not have a device that uses this type of connection(s). Another nice feature is that when changing between audio modes (from Bluetooth, to PC, to normal) a different light color blinks on left speaker letting you know that different mode has been selected. One thing I would have like to have seen is an optical input/output option for these speakers. Other than that I’m very satisfied with them.

    Note: For your reference remote controller uses one ‘CR2025’ battery.



    PROS: - Great Built Quality

    - RCA and USB connectivity

    - 44.1 - 96 kHz USB DAC

    - Included Remote Control

    - LEDs to help identify mode and power up

    - Bluetooth



    CONS: - Limited Bass and Treble Adjustment

    - No optical input/output option

    Reasonable speaker, but issues
    On the positive side, the speakers have reasonable sound quality, good volume, and a number of different connection methods.

    On the negative side: Bluetooth connectivity is reliable only within 5ft from the computer; at around 10ft you start to get dropouts; at 20 ft it's useless. The remote came with a dead battery. The instructions do not completely match the behavior of the unit.

    Bottom line: For the price, not a bad speaker. But it definitely has "issues"

    Very nice speakers
    I bought these speakers to replace an old stereo at work. Since everyone used to just plug their phones into it via a cassette adapter, I figured these would be better. They sound great in the space we put them in and are loud enough to hear over most of the work noise.
    The only thing I don't care for is there's no volume control on the speakers themselves. So if someone loses the remote or it breaks, there's no way to control the volume. As they don't get very loud even when the connected phone is at max volume.
