Short answer: the ELAC Debut 2.0 B5.2 for better sound quality, the Fluance Signature HFS for the lower price. The ELAC Debut 2.0 B5.2 ranks #47 of 87 bookshelf speakers at $329. The Fluance Signature HFS ranks #76 at $199.99, $129.01 cheaper.
What the ELAC Debut 2.0 B5.2 offers: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Erin demonstrated that a single high-shelf filter centered near 1.6kHz, about -2dB with Q near 2, substantially improves linearity. Moderate roughly +/-50-60 degree horizontal coverage balances room interaction and image focus. The front port makes close-to-wall placement practical. Erin measured F3 near 60Hz and F10 near 40Hz, useful extension for a compact 5.25-inch two-way. Harmonic distortion is mostly below 1% at 86dB/1m, and low-frequency distortion is better than its size might suggest. Compact cabinet and inexpensive pair pricing make it a workable EQ-assisted desktop or small-room system. Watch for: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance. Native response spans roughly -2.6 to +4dB around the mean, so this is not a neutral speaker without correction. Sensitivity is only about 83dB after correcting the shelf, demanding materially more amplifier voltage than ELAC’s 86dB specification implies. Vertical response changes substantially outside roughly +/-10 degrees of tweeter height. Dynamic compression is the larger limitation: at the highest sweep level it loses roughly 1-1.5dB through the midrange, and even the 86dB trace shows unusual nonlinearity that may involve crossover heating. At about 96dB, multitone distortion rises audibly around 600Hz; an 80-120Hz subwoofer crossover helps but does not turn it into a high-output design. Erin recommends the larger B6.2 instead when EQ is unavailable.
What the Fluance Signature HFS offers: Front-facing port and pre-installed wall-mount brackets make it flexible for bookshelf or surround/height duty. Distortion in the low end is well controlled per the measurements, and the glossy front baffle adds a touch of style well beyond the budget price. Watch for: CEA2034 spinorama shows serious flaws in the midrange - both the direct sound and the directivity are compromised, a combination the reviewer flagged as poor for controlled listening tests. Multiple attempted EQ fixes “could not rescue” the sound, and the reviewer said the result was “close” to the lowest possible rating. Online reviews seeded by the company were positive; the reviewer’s measured and subjective experience was not.
Buy the ELAC Debut 2.0 B5.2 if sound quality matters more than the price. Buy the Fluance Signature HFS if the price matters more than sound quality.
If sound quality matters at all to you, skip the Fluance Signature HFS. It ranks near the bottom of the 87 bookshelf speakers, so look higher up the list instead.
