JBL Customer Comments

Many JBL audio speakers have customer comments, which can be helpful when deciding between different audio speakers. The following are a few comments for their audio speakers.

  • "I have another big brand 12" sub, but to my pleasant surprise the ES250BPK surpassed it by a wide lead! High sound quality (no distortion even at high volumes), plenty of power, deep and intense bass at low volumes (the walls of my house are solid bricks and "I can feel goooood" the vibration when I put my hands on them)! Design sleek and compact, simplicity of installation and quiet operation. To be perfect could come with remote control and wireless connection, but these features are only available in much more expensive subs and we do not need if you have a receiver of high quality with accurate calibration." - ES250P subwoofer comment.
  • "Driving these with a Yamaha RX-497 and with a Boston Acoustics sub, these are excellent sounding speakers and are an amazing value. Really good mids, perfect highs and appropriate bass (given the 6 inch woofer in a very large bookshelf enclosure). These speakers are so large that they will not really fit on a bookshelf; you'll want to use some decent speaker stands (24 inch is what I use and when seated they sit at ear level). I like the sound from these so much better than Klipsch (as always, do your own sound tests before buying). Highly recommended!" - ES30 comment.
  • "This speakers have a great sound in combination with my JBL L8400 subwoofer and JBL lc2 center speaker! I am using a Denon receiver to my JBL studio line system. This combination gives a great sound by playing music and films! A super all around system to hear." - Studio L820 comment.
