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.

Questions and Answers
Bass disperses very well through the bottom, vibrating the surface it is sitting on. Different surfaces alter how long notes trail and a bit in timbre. Upper mids and highs, especially high female vocals, may sound localized, which may contribute to a little feeling of "tinniness". The bass is very good for a speaker ~$50. The mids and highs are neutral and a little smooth, not mind-blowing, but quite decent for $30 speakers.
The 20 hour battery life is great, but you should know it is charged by usb. I also quite like the size and weight and look. If you are looking for a low cost portable speaker, this should be a candidate on your list. If you mainly like good tangible bass, there may not be a better sounding portable speaker under $100.
PROS: Clean, full, tight, deep, well-dispersed bass
Neutral and resolving for a portable mono speaker under $100
Big sound in small box
Everything well thought out... form factor, ease of use, battery life, accessories, even the packaging container which also sounds good as a surface for the speaker btw.
CONS: Mids and highs may sound at times like they are coming from a small, easily localized place
Not a con if you use two at once (don't do that lol), but it is a mono speaker, and a mono speaker will inherently present stereo data kind of mushed with odd dynamics.
PROS: - Good bass on some surfaces. For example, when held on a hollow wood door it produces loud, deep bass, down to about 40Hz, as advertised. It's loud enough to be heard throughout a house. Also works well on thin wooden tables.
- Convenient to use: it switches on automatically when the cable is plugged in, the battery is internal and rechargeable so there's no need to replace it all the time, easy to charge (simply use a USB port).
- Fairly loud: loud enough for the audio from a movie, even when chewing loud, crunchy chips in a moderate-sized room.
- Small and easy to transport
- Comes with good quality cables
CONS: - Sound quality is bad. The bass is alright when used on the right surface, but the midrange and treble are horrible because they are produced by an extremely low-quality speaker: it's the type of speaker that is commonly used as the internal speaker in a computer tower, which is basically the lowest-quality speaker possible. Vocals sound muted, treble is virtually non-existant, and nothing in the music is "clear". I plan to open up the device and replace this speaker sometime (I already opened the device before to see what type of speakers it uses, and to check out the electronics).
- Although the bass is fairly good on some surfaces, such as hollow wooden doors and thin wooden tables, it's generally hard to find a good surface. Wooden surfaces thicker than about an inch are too rigid for the device to produce any appreciable amount of vibration in them. Rock surfaces (such as granite) don't work at all. Some thin metal surface work, but tend to vibrate and sound "tinny", as expected.
- When the bass gets really loud, the device tends to shake across the surface. Cleaning the gel pad tends to prevent it from doing this, but in some cases it will still do it.
Thank you for your feedback and very thorough review of the speaker. If you don't mind me asking did you also try glass surfaces and if so any take on how that worked out for you? If you weren't planning on continuing to use the speaker and no longer have a use for it I can assist with creating an RMA for a return for you. I would just need an order number to get the process started. Sorry for any dissatisfaction you may have had.
PROS: It has really impressive sound for such a small speaker and the bass performance is where it really kind of surprises you. The battery life makes it a great travel speaker and the on/off control is pretty cool so you don't accidentally leave it on.
CONS: You have to make sure you always have it on a resonating surface to get the impressive bass performance. Although it's not showing any signs of wear yet (aside from fingerprints), the finish looks like it may not stand up to much abuse. A case would have been nice since it needs an auxillary cable to connect it to your devices.
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.
PROS: Clarity of speaker
I am very happy with this unit.
PROS: Good loud sound from a little source.
Great Battery Life
Nice unobtrusive look
CONS: For the price, no cons whatsoever!
I bought the incredible Jam Box, and yes, it sounds better. BUT IT COSTS FIVE TIMES AS MUCH AS THIS ONE!!!
PROS: Incredible for the money.
CONS: None for the money.
PROS: Amazing. Great sound from a very portable speaker.
PROS: You won't believe the sound that comes out of this small box! Sit it down on a table or most anything and it uses that surface as a resonator for bass. Nothing to control.. no buttons on it at all. Just plug in your iPod or similar device using a stereo mini plug .
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.
