    8 Inches 3-Way Bookshelf Speakers (Pair) - Black

    Get some sweet sounds from these moderate sized bookshelf speakers from Monoprice!

    These attractive speakers feature a single 8" polypropylene woofer, a 4" polypropylene mid-range driver, and a 1/2" dome tweeter on each unit. They have a sensitivity of 88 dB and can handle 120 watts of power, making them a perfect match for moderately powered amps.

    The flat black wooden cabinet measures about 16 7/32" tall, 11 3/8" wide, and 9 3/8" deep. They can be mounted vertically or horizontally on a bookshelf or vertically on a wall, using the keyhole bracket on the back of the speaker enclosure. The spring-loaded speaker wire connectors can accept wires up to 16-guage thick.

    Outstanding sound quality, an attractive finish, and solid performance make these the perfect stereo speakers or replacements for smaller satellites in a 5.1 channel home theater configuration. Combine two pairs of these with one (or two) of our 12" powered subwoofers and you will have a 5.1 sound system that will rival that of your local theater!

    Great low cost speaker pair!

    Pros: Low cost with great sound
    Lots of bass!

    Cons: Cheap connectors, had to play with one to get speaker wire connected.

    Needed a set of speakers on a low budget and thought these looked promising. Boy was I right. They sound great for a pair of speakers under $100.

    I got bit by poor QC

    Pros: Cheap.
    Decent looking.
    Reasonable performance IF you receive good components in the box.

    Cons: Bad component risk.
    Poor quality control.

    Had great luck with the 6.5" bookshelf speakers, so decided to try these out in my garage. Had trouble with one speaker straight out of the box. Spring-loaded terminal clip never made good contact, causing audible noise and attenuation. I partially alleviated this problem by tinning and bending my speaker wires. While testing in this state I turned volume to midway, heard strange noise from this woofer, then my amplifier power supply cut out into self-protection mode. I discovered that the woofer voice coil had a dead short.

    Not worth shipping $$$ to Monoprice for an exchange, I instead ordered a new 8" woofer and spring terminals and will fix it myself.

    The other speaker looks and sounds great, so I drew the short straw. Cross your fingers when you order these!

    Decent, Mid-Range Doesn't Work

    • unCard,
    •  Moore, OK

    Pros: Clean Sound
    Loud @50W (Per Channel)

    Cons: Mid-Range NONFUNCTIONAL

    I got these to setup a small 2.0 Home Theatre option over the crappy HDTV Speakers. While these are MUCH better than TV Speakers, both speakers arriving with the Mid-Range not working is not that great. Yes, 4 Stars with the mid-range driver nonfunctional as the bass driver seems to carry the weight and produces decent sound.

    // Setup
    SMSL 50x2 (Amp)
    8" 3-Way BookShelf Speakers (Pair)

    // Sound
    Despite the Mid-Range not working, they sound pretty nice. I loaded some Music and you can hear can tell where the mid-range is not operating. I loaded some TV shows and Movie Trailers they punch like one would expect from a more expensive option. Clearly, the bass-driver carries where the mid-range is failing, but it could be better if all drivers were operational.

    // Way Forward
    I won't be returning these as they work for what I need them for. Monoprice folk... you guys need to check in on Manufacturing QA and see where this issue is coming from. There are a lot of reviews about this Mid-Range failing to operate. Get a better crossover or wiring. I'll crack these puppies open when I get reference monitors for a better theatre setup and see if I can figure out the issue and submit my results then. Until then, please look into this issue. You guys make good products, but when products are half functional, its hard to recommend you to people.

    Sounds nice, looks nice, not fully functional.

    Pros: Look great, sound great, very cheap for what they are.

    Cons: 4" subwoofer not functional.

    These speakers showed up today very nicely packaged and in a timely manner. Got them all wired up in a 3.1 system with the premium center speaker (11948) and the 12" powered subwoofer (9723). The combination paired with my Sony receiver sounds great. However, it lacked warmth. I had read about the issue with the 4" subwoofer on these units not working, and sure enough, the 4" subwoofers were producing no power at all. Tried a different receiver, tried different media, tried everything that had been suggested in the responses to reviewers experiencing the same problem. Nothing brought the 4" subwoofers to life. Other than this, the look of the speakers is great if you are into minimal/modern equipment. Would be 5 stars if they were working properly. The sound would probably be much better, with a fuller mid-range.

    Hello Cameron,

    My apologies for the failure experienced with the 4" drivers on these speakers. I see that you already have a replacement in progress. As soon as you receive the new pair of speakers and have had a chance to try them out, please keep us updated through this review. Sorry again for the trouble and thank you for your feedback!

    Excellent value product

    Pros: Value and quality of the product is excellent.

    Cons: Wire connectors could be better, but not a big issue for me when looking to the whole product value and quality.

    The speakers sound is great. I have an Onkyo A/V receiver with Klipsch (smaller) speakers in the back and the Monoprice speakers in the front and works really good. I think would sound better if I would have 2 sets of Monoprice speakers (that cost less than one set of Klipsch speakers).
