Short answer: the ELAC DBR62 for better sound quality, the Polk Reserve R100 for the lower price. The ELAC DBR62 ranks #55 of 125 bookshelf speakers at $678.97. The Polk Reserve R100 ranks #95 at $649, $29.97 cheaper.
What the ELAC DBR62 offers: Two-way design with a 6.5” woofer and 1” dome tweeter in a shallow waveguide, with the tweeter positioned close to the woofer for near-point-source coherence - giving more vertical listening leeway than typical two-ways. Notably forgiving of placement and aiming: sounds good from directly on-axis all the way to 30° of toe-out (parallel with the rear wall), making it more room-independent than many speakers this price. Wide horizontal radiation of about ±70° until the tweeter starts beaming, right in the reviewer’s preferred sweet spot. A mild, wide-Q bass bump centered around 100Hz adds a bit of extra punch that the reviewer personally likes. On-axis linearity within about ±2.5dB, with a strong measured preference score of 5.3. Distortion stays below 3% at both 86dB and 96dB until around 50Hz. Vertical sweet spot of about ±10-20° works well for multi-row home theater seating. The reviewer calls it “the epitome of a good speaker” for its price, with no reservations recommending it. Watch for: A slight recess in the 1-2kHz region reduces vocal presence somewhat compared to other speakers in direct comparison. A mild hot spot around 4-5kHz can read as slight sibilance when pointed directly on-axis. Low-to-mid sensitivity (about 84.3dB) combined with a current draw that behaves like roughly 2.4 ohms between 100-200Hz means it’s best driven by a dedicated 4-ohm-capable amplifier rather than an AVR. A diffraction dip from the baffle edge is visible in measurements - typical of any standard rectangular-baffle speaker and not correctable without a much more expensive curved-baffle design. Multitone distortion testing suggests some potential midrange distortion could be audible on certain material, though the reviewer didn’t personally notice it. Minor resonances appear around 700Hz and 1-1.5kHz, possibly tied to the enclosure, port, or cone/surround edge termination, though their audible impact appears minimal. F3 of 53Hz means a subwoofer is still needed for real bass extension below about 40Hz.
What the Polk Reserve R100 offers: Compact cabinet, unusually useful bass for its size and well-controlled woofer breakup. Erin measured F3/F10 points of 68Hz/49Hz, and the X-Port vent avoids much of the chuffing and pipe resonance common to budget rear ports. The 5.25-inch Turbine Cone woofer and 1-inch Pinnacle ring-radiator tweeter produce good detail at moderate levels, while listening roughly 20° off-axis reduces part of the elevated top octave. Watch for: Erin measured only about 85dB sensitivity and the impedance reaches 3.6 ohms, so it is neither efficient nor an entirely benign AVR load. The treble runs roughly 3dB above the midrange and becomes aggressive above about 85dB SPL. A directivity discontinuity through the woofer/tweeter crossover means EQ cannot fully repair the power response, and a 400Hz impedance feature plus 500Hz-1kHz response irregularity suggests a cabinet or system resonance. Substantial low-frequency compression at higher playback levels limits clean dynamics.
Buy the ELAC DBR62 if sound quality matters more than the price. Buy the Polk Reserve R100 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Polk Reserve R100. It ranks near the bottom of the 125 bookshelf speakers, so look higher up the list instead.
