#66 Dynaudio Contour 20i: $5750 per pair Safe and Sound HQ eBay

Pros: Two-way design with a 1.125” Esotar2i silk dome tweeter and a 7” magnesium silicate polymer woofer in a vented enclosure. A shallow bass rolloff profile lets it sit closer to a wall (about 1-2 feet worked best in testing) without becoming boomy, and makes subwoofer integration comparatively easy. Very wide horizontal radiation (about ±70° through the midrange) gives an enveloping, spacious sound in a suitably sized room. On-axis response holds within about ±3dB overall and ±1.5dB through the midrange. Attractive build quality with a distinctive metal front baffle and gloss finish options. Long-term compression stays good up to 96dB, and short-term compression is within about 0.5dB at that same level. Measured bass extension of 56Hz (-3dB).

Cons: Notably room-dependent: sounds too bright in the lower treble in smaller rooms with close sidewalls, needing sidewall absorption to sound neutral, while performing better in larger or more open rooms without that treatment. A roughly 2dB lift in the lower treble combined with wide dispersion means more energy reflecting off sidewalls than some listeners will prefer. Relatively low sensitivity (about 82.5dB measured). Unusually sensitive to amplifier output impedance: high-output-impedance amps like tube or SET designs introduce up to a 2dB dip in the midrange, making the sound more mellow rather than “warmer,” the opposite of what many tube-amp buyers expect. Elevated harmonic and multitone distortion around 700Hz, which the reviewer attributes to typical cone-edge/surround behavior common across many driver brands, though it stands out on the measurement graphs. An upper-midrange dip around 2kHz can reduce attack and clarity on vocals and brass instruments. Vertical listening window is fairly narrow (roughly -20° to +30°): moving outside that range causes a noticeable tonal shift, unlike coaxial designs that tolerate more vertical movement.

How it compares: Just above it: JBL L100 Classic MKII - $2950 cheaper, 7.5Hz higher bass extension (-3dB). Just below it: HiVi Swans 3.1A Sehlin Sound Solutions mod - $5385 cheaper, 4Hz higher bass extension (-3dB).
