Summary: These are well paired with Harmon Kardon AVR 1700 receiver. I only use a pair of these in stereo. Used mostly for music in a 700 sq foot room. On occasion I turn up the volume and these crank out the sound. Very pleased would buy again.
Summary: First of all JBL L830 are very good speakers if you like highs and mid-range sound. Crystal-clear the sound is beautiful but the lows(bass)are not good,when i raise volume the speakers rumble. Couldn't enjoy the highs without the lows so i send them back.
Summary: I replaced my realistic optimus 5 speakers with these I was worried there might not be enough bass, but there is plenty. I have them hooked up to a 1978 onkyo tx 4500 56 watts per channel. I don't even need half volume my CDs sound awesome.
Exceptional tone balance and clear sounding = high value.

Summary: I was replacing my 20 year old M&K S1B speakers. After reading several reviews I narrowed the field to these. They out perform my old M&K's which, at the time of purchase, cost about double the current price of these JBL's. The detail and clarity are top tier. I am now hearing things I didn't hear before. The first cd I played was a piano solo by David Lanz. Even at low volume I can hear David's foot tapping on the floor or foot peddles of his piano.
Summary: Do you need a subwoofer? These are great speakers. Some reviews insist you’ll need a sub-woofer; some say the bass is already great. I have JBL S26 speakers in my office. They are a 6 inch 2 way, about the same size as the L830 and have the same bass response. The S26s are in a small room and against the back wall. They are completely satisfying by themselves. No sub-woofer needed.
Summary: Took a week or so for these to open up, and for me to find the proper placement -- upright, on top of my bookshelf credenza, not too close to the wall. Using these speakers in my office for 100% 2-channel music listening with black grill cloths affixed. They're being driven by upper end A-S2000 Yamaha amp. Very good clarity, good balance across the audio spectrum. Good detail. Not tiring to listen to. Primarily listening to jazz, old skool r&b, and classical music.
This is probably the best purchase I've ever made.

Summary: Don't could on these speakers giving any sort of bass response, but... combined with a good subwoofer, you won't believe how great the sound is. The ultra-tweeter makes the output from an HK990 the best thing since sliced bread.
