let's see if we can agree on some sounds that we have both heard so we'll know if our perceptions are roughly equivalent.
on L100
led zeppelin 4 " black dog" the vocals sound a little shrill when plant screams "HEY, HEY" I don't believe this is a fault of the speakers ....
Same album "when the levee breaks " the harmonica sounds a little shrill this may be the speakers.
Same album ! "when the levee breaks " the drums make a gratifying THUMP but you can also hear the "skin" on the drums , I hope you know what I mean because it is very tough to describe.
The 4344 should have more thump than the L100's , maybe not as much skin ?? both woofers in question are aquaplassed which is , I believe, a prime source of the THUMP in a round about way ( by adding mass to the cone E145 don't thump as much but is very quick)
Your bass content seems mellow ?? what does when the levee breaks sound like to you thru those speakers ?
