Short answer: the Infinity IL10 for neutrality; the Sonus Faber Lumina II for looks and brand cachet. The IL10 is impressively flat for a budget bookshelf, with resonances at 600 and 5kHz that show up as distortion spikes at 96dB SPL/1m. The Lumina II is handmade in Italy with a gloss baffle and a leather-wrapped cabinet, but a persistent high-frequency lift makes it forward and bright on or off axis.
Buy the Sonus Faber Lumina II if you want one new; the Infinity IL10 is discontinued, so only look for it used.

The Two Speakers In Full
Infinity IL10: $160 per pair used Discontinued eBay
Pros: Impressively flat for a budget bookshelf. Predicted in-room response is good aside from a bit of excess energy here and there. Distortion at 96dB SPL/1m stays low and controlled outside two narrow resonance-driven peaks. Measured bass extension of 59Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Resonances at 600 and 5kHz, which show up as distinct distortion spikes at 96dB SPL/1m in the same frequency regions. Discontinued.

Sonus Faber Lumina II: $1,600 per pair Crutchfield eBay
Pros: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet: genuinely nice-looking speaker with real brand cachet. Bass extension is competitive for the size, reaching about 50 Hz in-room with mild compression and good distortion figures, so higher output levels and greater listening distances aren’t a problem down to that point. About 20 dB of dynamic range at typical listening levels (73 dB at 4m), which comfortably covers most music without the tonal balance shifting as instruments and vocals peak. Off-axis behavior is consistent: toeing the speakers 20-30 degrees out doesn’t meaningfully change the in-room high-frequency character, so placement flexibility is good once you’ve dialed in the tonal balance. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Not a neutral speaker: has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out. A slightly nasal quality traced to a resonance around 1 kHz that EQ can address. The reviewer needed to trim treble by about 4 dB on his preamp to get the tonal balance he wanted, meaning most listeners will want equalization available to fully enjoy this speaker. At roughly the same $1,000ish price point, alternatives like the Ascend Acoustics Sierra 1 V2 measure more linear (with a tradeoff in distortion and crossover-region directivity), and the Dynaudio Emit 20 offers deeper bass extension and lower compression at the cost of a more deliberately colored tonal signature.
