Anyone know what the response curve looks like? What's it like below 100 Hz? I have copy of L110 response curve. I own L110 and are pretty fantastic. (And how much power is minimal for L110? I have Yamaha 100W/channel.)

For normal household use 100 watts is good.

Sorry, can't tell you what the curve is, but I still have the owners manual when I purchased my L100a's new in 1977. JBL recommended 150 watts. I'm sure your 100 watts will do just fine. As a teenager at the time I spent all my money on those speakers and didn't have much left over for other equipment so I ended-up with a "small" 50 watt amp. Hey, I was happy as heck I owned a pair of JBLs!, all my friends were jealous. ~ Mark

Here is a curve I measured years ago. I found the curve looked significantly better when measured on the woofer axis. Typically we measure with the mic on the tweeter's axis. I wish I had saved one done that way for a comparison.

Looking at the 1/3 octave plot in the 4311 brochure, it looks like my L100 is pretty much within specs. :bouncy:
