Verdict

The Energy Sistem Classy is a 3.34 kg portable retro-style Bluetooth 5.3 speaker that delivers a powerful 150W maximum output (100W on battery) through a 5-inch woofer, silk dome tweeters, a 6.5-inch passive radiator, and integrated DSP across a 45 Hz to 20,000 Hz frequency response. Key advantages include an integrated power supply with a fast 1.5-hour charge time, a 4,500 mAh battery offering up to 10 hours of playtime, independent analog bass/treble knobs with a dedicated Extra Bass button, and versatile playback options via a 3.5mm AUX port or a USB-A port that supports lossless FLAC files. However, the speaker lacks any official waterproof or dustproof IP ratings and depends on the basic SBC audio codec instead of higher-fidelity wireless alternatives.

What customers dislike about Energy Sistem Classy?

  • Relatively heavy and bulky for a highly portable speaker, weighing over 3.3 kg
  • Lacks water resistance or an official IP rating, making it risky for poolside or rainy outdoor use
  • Relies on the basic SBC audio codec instead of high-definition Bluetooth codecs like aptX or AAC
  • Lacks built-in subwoofer components, relying instead on a passive radiator for its low-end
  • No modern smart features such as integrated voice assistants or remote smartphone app control
