Small Bluetooth speakers try to compensate for their small size by boosting the low frequencies which can lead to an uncomfortable listening experience and an inaccurate muffled sound.
• Harmonics in the mid to high frequenicies are an important part of what makes live music sound "live". To reproduce these harmonics typically requires larger cabinets and higher costs.
• The electrostatic panels in the treVolo S and treVolo 2 require very little power to move and so they reproduce audio in a much more accurate way.
• A conventional speaker design requires a lot of power to play music clearly at a low volume. With inadequate power most Bluetooth speakers sound stage collapses and the frequency response changes as the volume decreases. This results in a subpar audio experience and can sound muffled or lose that "full" sound experience.
• Balancing the volume and quality of the audio can be difficult, especially when the only solution is to turn it up when you're trying to relax.
