    Premium Portable Sonic Resonance Speaker

    To get loud booming sound, you generally need two things in a speaker, large cones to move large volumes of air and a lot of power to drive those cones back and forth. Without those, you get thin tinny sounds and not much volume. That in a nutshell is what you get from most mini portable speaker system designed for use with laptops, music players and cell phones.

    The Portable Sonic Resonance Speaker from Monoprice changes how audio is delivered, by phasing with any clean, smooth, flat surface you attach it to and turning the entire surface area into one huge driver. You get even more air pulsing surface area than you get from traditional cone drivers.

    The result is loud, clear and bold audio. Perfect when you want to share audio such as in a presentation, entertaining friends or just setting the right ambient mood.

    The Portable Sonic Resonance Speaker is basically a specially designed transducer that efficiently transfers sonic vibrations to the surface it attaches to. The base of the speaker is a specially treated soft silicon pad that adheres to any clean, smooth, flat surface. It can be removed and replaced several times. When dust and dirt accumulate on the pad over time, it can be easily wiped clean with a damp cloth and instantly be brought back to life.

    The video is a demo of the speaker. While it won't be able to truly show the dynamic impact of just how well this device performs sonically, it is a good introduction to what the device is and how it works.

    Not much better than my phone's speakers

    Pros: Color?

    Cons: Sound

    I followed all of the instructions, kept the bottom of the speaker clean, tried different surfaces and, no matter what I did, I was not able to hear any discernible low end out of the speaker. "Sonic resonance" sounded fancy, but there's nothing advanced about the sound. I have been very satisfied with the vast majority of my Monoprice purchases, but I cannot justify the price and would not recommend this one.

    Pros: Sounded great for the 1 min that it worked.

    Cons: Never worked after 1st plug in - now I'm wasting time dealing with the online chat - hoping to get something that works.

    Finally received the product after having to contact the shipping company and Monoprice - the shipping company said that they never received the product to ship (only received the transmitting document). Called Monprice and they said they would ship the product out again, got the product the next day, plugged it in and it worked and sounded great (for what it is) but after the 1st use (only about 1 min) could not get it to work again. Tried calling Monoprice for help but was placed on hold, so now I'm trying to get help online. It appears that I need a new unit, so an RMA has been issued and now need to wait for Customer Service to send me an email with instructions to return. Not a good experience.

    Cons: Poor sound quality, especially Bass.

    I have owned several Monoprice portable speakers in the past, and was always very impressed with the sound quality for the price. Unfortunately, this speaker (6914) is not one. I came back looking for another 9953 resonance speaker which had fantastic bass but seems that is no longer available. I went with the "premium" model in hopes of replicating part of that sound. I tried many surfaces to no avail. For the price you would do much better to buy two of the 8595 and call it a day. Disappointment in this speaker is the word for what I have come to expect from Monoprice.

    Not working

    • Rob,
    •  Johnson City, TN

    Pros: Hard to tell, since it works for about 30 seconds and then dies, after being charged all night.

    Cons: I can't figure out if it's JUST that the included headphone-jack cable is bad (which it most certainly is, as the first thing one hears when plugging anything in is crackle and fuzz, and this happens anytime it's moved), or the speaker itself.

    Planning on returning this, if possible really disappointed!

    Big things come in small packages

    Pros: Great sound quality (depending on the surface you place it on.)
    Long battery Life / Rechargeable

    Cons: Sticking surface difficult to keep clean for proper adhesion.

    Great little toy, about the size of those old nokia brick phones. Simply plug in the 3.5mm audio jack and it works. It's about 5 times louder than my laptop speakers and really clear. Though how clear depends entirely on what surface you place it on. For the most part tables/counters/most glass, makes it sound great. Deep low tones, when it's on a good surface. I usually get between 8-10 hours of play time on a solid charge. Really convenient for on the go speakers. I would buy another one if I had any use for it.
