Pretty good sound/build quality and value at $100, with caveats.
I received a Turbo X last week, and here are my impressions after several hours of testing.
First, I believe one has to temper expectations with a small, portable speaker like this. With a speaker this size, there is only so much internal volume and space for drivers, amps, etc. The standard laws of physics apply – there is only so much bass extension, dynamic capabilities, and overall volume possible in a speaker this small.
If one expects pounding bass and party-level volume from a speaker this small, I think that expectations are misguided.
With the above said, the question is whether this speaker can capture the essence of music in an enjoyable fashion at satisfying volume levels, and whether it can do this better than competing models. IMO, the Turbo X does a pretty good job at the above, with some caveats.
IMO, the Turbo X has good bass and midrange for a speaker in this class, but the high frequencies sound a bit dull and sound a bit artificial/processed. Some on-line reviewers have measured significant high frequency roll-off, which probably accounts for what I’m hearing. It would be nice if the app allowed for some treble boost.
Also, when the volume is pushed towards max with Turbo mode, I believe some distortion kick in and sound quality suffers.
However, with the above caveats, I still think the Turbo X is a great value at $100. For comparison, I also have a Bose Revolve+ (received it as a gift from work and would never pay $300 for it). The Bose has a higher max volume, but the sound quality suffers to a higher degree as the volume is pushed. The bass becomes compressed and the sound becomes overly midrangey – not very pleasant. The Bose seems to have better high frequency extension, but the Turbo X has better bass.
So, ultimately, from a value standpoint, I would choose the $100 Turbo X over the $300 Bose Revolve+. I feel that the Turbo X has a more natural sound, even with its bit of high frequency dullness.
Some other observations: - Build quality is nice. It feels fairly heavy and solid. It is also attractive. - The I/O port cover is a nice touch and thoughtful design. - The inclusion of the aptX and ACC Bluetooth codecs is a plus. I’m using aptX with my android phone. - The battery on/off switch would be better if it was a slide switch rather than push button. I can see the battery switch getting inadvertently turned on in transport. - The Turbo mode needs to be on to achieve any real volume. Seems gimmicky. - Turning the unit on is a bit wonky. Seems like the power button needs to be tapped more than once. - The power supply brick is bulky compared units that charge with a wall-wart or USB.
Vastly overrated - sound quality ok and overall volume ok, but for the price and all the online hype, was expecting much more. I now have 5 different monoprice Bluetooth speakers ranging in price and size . Party speaker loudest and biggest...great value. An older Brick speaker smallest and least cost. All else are in between but all sound about the same. The turbo bottom on RIVA is like a boost mode , without it, it’s so quiet ( even full volume ) you have to use turbo ..,just a gimmick sound about the same as any $40 Bluetooth speaker , thus too costly for what you get
Wish I would have known before I ordered it as Monoprice didn't even mention the battery is no good. At least on Amazon it says that the battery doesn't work. If you buy it your probably gonna have to keep it plugged in if you want to use it. Other than the battery it's a great sounding speaker.
