#3 L-Acoustics X15 HiQ eBay
Pros: Vendor Spinorama data gives preference scores of 5.31 standalone and 8.06 with an ideal subwoofer, the highest ideal-subwoofer score in the 15-inch ranking. Listening-window narrow-band deviation is a low 0.186 and predicted in-room smoothness is 0.703, so vocals and stage-monitor mixes stay clean. Bass reaches about 73Hz (-3dB) with a 138dB maximum SPL from a 21kg coaxial cabinet. Measured bass extension of 73Hz (-3dB).
Cons: This passive monitor needs an L-Acoustics amplified controller such as the LA4X or LA12X to work at all. Its narrow 40° x 60° pattern suits a stage monitor but covers less of a room than wider mains. Bass reaches only about 73Hz (-3dB), so a subwoofer is still needed for full-range music.
How it compares: Just above it: FBT Promaxx 114A. Just below it: Vue Audiotechnik H-15.
