#22 ELAC VELA BS 403: $2,899 Amazon

Pros: JET 5 folded ribbon tweeter pairs with a 6” aluminum/paper sandwich woofer for extended, well-controlled bass - Erin measured usable in-room extension to about 50 Hz, deeper than JBL’s competing L52 Classic despite lacking that speaker’s mild upper-bass bump. Compression stays within about 1 dB above 100 Hz up to 102 dB, on the better side of normal for a bookshelf this size, indicating good dynamic and transient capability. Wide, spacious soundstage radiation. Overall neutral voicing that Erin called “a really good speaker,” from the looks to the sound.

Cons: Deliberate dip-and-peak voicing in the crossover region around 2 kHz reduces attack and clarity in the mids and highs - intentional per ELAC’s design, but not to Erin’s personal preference. Lower measured sensitivity (84.3 dB) means it wants more amplifier power than average to reach the same levels. Multitone distortion roughly triples, from about 1% to 3%, between 88 dB and 96 dB output, so it’s happiest at moderate listening levels. A minor distortion bump shows up around 800 Hz in the data, though Erin didn’t hear it.

How it compares: Just above it: Revel M126Be - $1501 more, 1.7Hz higher bass extension (-3dB). Just below it: Emotiva Airmotiv XB2 - $2350 cheaper, 1.7Hz higher bass extension (-3dB).
