Short answer: the ELAC Debut 3.0 DB63, though both sound hollow in the mids. The DB63 pairs a 1-inch aluminum dome tweeter with a partial-lens waveguide and a 6.5-inch aramid fiber cone woofer, but a roughly 1.5dB dip from 300-600Hz reduces vocal warmth. The Cerwin Vega LA165 has decent cabinet damping for the price but a far-from-neutral balance, with a 2-3dB cut through the vocal fundamental range giving it a hollow midrange.
On the Cerwin Vega LA165 side: Passive bookshelf design with decent internal cabinet damping/batting material for the price. The tradeoff: Overall tonal balance is far from neutral: a 2-3dB cut through the vocal fundamental range gives a hollow midrange.
The case for the ELAC Debut 3.0 DB63: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer. The tradeoff: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow.
Buy the Cerwin Vega LA165 if the price matters more than sound quality. Buy the ELAC Debut 3.0 DB63 if sound quality matters more than the price.
The Cerwin Vega LA165 is not a sound-quality pick. It sits near the bottom of the 130 bookshelf speakers; there are better options higher up.

Pros: Passive bookshelf design with decent internal cabinet damping/batting material for the price. Delivers noticeable mid-bass punch around 100-120Hz, giving a sense of kick and impact that fans of the brand’s traditionally punchy sound may appreciate. Horizontal radiation of about ±60-70° lands in the reviewer’s preferred range for soundstage width. Reasonably priced at around $270/pair. Measured bass extension of 66.7Hz (-3dB), with a measured sensitivity of 86.2dB.
Cons: Overall tonal balance is far from neutral: a 2-3dB cut through the vocal fundamental range gives a hollow midrange, while a dip around 2-4kHz removes attack, snap, and clarity from snares and other transient sounds. An elevated upper treble region adds a sibilant, edgy quality (though not as extreme as some pricier speakers with similar issues). The manufacturer’s quoted 33Hz-20kHz frequency response is essentially meaningless without a tolerance bound - actual measured extension is closer to an F3 of 67Hz and F10 of 47Hz, roughly 19dB down at the claimed 33Hz. Measured sensitivity (about 86.2dB) runs several dB below the manufacturer’s 90dB spec regardless of which impedance figure is used to convert it. Significant modal ringing in the midwoofer cone, confirmed by testing the driver in isolation, ties directly to elevated distortion and resonances around 700Hz-1kHz from a cone-edge/surround mismatch. Multitone distortion crosses the reviewer’s 3% threshold at 96dB, adding graininess through the midrange and upper-mid. Unusual compression behavior shows the treble actually gaining level (rather than compressing) under both long-term and instantaneous testing - an atypical and not particularly desirable trait. Directly compared to the similarly-priced Polk XT20, which the reviewer considers clearly superior in linearity, distortion, and bass extension.

ELAC Debut 3.0 DB63: $499.00 per pair Amazon Crutchfield eBay
Pros: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Shallow bass rolloff (F3 76Hz, F10 40Hz) allows placement close to a wall without excessive boominess, useful for smaller living rooms. Solid measured performance for the price: on-axis linearity within about 2.5dB, impedance dipping only to about 4.4 ohms (easily AVR-driven), and roughly 20-26dB of usable dynamic range. A clear improvement over its sibling ELAC DB62, which has a sibilance issue tied to the crossover that can’t be fixed with EQ. Wide horizontal radiation of about ±60°, giving a spacious soundstage. Distortion looks good at a moderate 86dB and still reasonable at 96dB. Takes well to EQ correction - the reviewer provides a specific filter set (a low-shelf boost at 650Hz plus peaking cuts/boosts at 550Hz, 660Hz, and 3kHz) that meaningfully smooths out its known deviations. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 86.2dB.
Cons: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow. A high-Q resonance around 650-750Hz shows up clearly in measurements, though the reviewer couldn’t reliably hear it in his own A/B testing. A dip around 2-3kHz (roughly 1-2dB) slightly reduces speech intelligibility and attack in the upper midrange. Directivity droops above about 2kHz as the midwoofer narrows toward its beaming frequency while the tweeter’s pattern behaves differently - an inherent trade-off of physically separated drivers that can’t be fully corrected without introducing other issues. Multitone distortion crosses the reviewer’s 3% threshold in the 200Hz-1kHz range, and adding a subwoofer at an 80Hz crossover only modestly reduces it. Toeing the speaker away from the listener loses noticeable top-end air and cymbal energy, giving a softer upper register. Practical loudness ceiling is around 90dB at typical listening distance before midrange distortion and bass attack begin to degrade. Still needs a subwoofer for extension below about 40Hz.
