#5 KV2 Audio EX12: $3,480 eBay

Same family: the KV2 Audio EX6 (smaller model, estimated 3.6/5), the KV2 Audio EX26 (smaller model, estimated 3.6/5), the KV2 Audio EX10 (smaller model, rated 3.7/5), the KV2 Audio EX28 (smaller model, estimated 3.8/5) and the KV2 Audio EX15 (larger model, rated 4/5).

Pros: A highly accurate specialist 12 inch PA speaker with deep bass, very clear vocals and controlled throw. A 6.62 ideal-subwoofer preference score and 52Hz bass extension from medium-quality vendor data make this one of the strongest measured specialist boxes. Its 3-inch-diaphragm compression driver, 133dB claimed peak and 80° x 40° horn target high vocal clarity and controlled throw. Measured bass extension of 60Hz (-3dB).

Cons: The 27.4kg enclosure and premium price make it much less portable and accessible than the mainstream leaders. User controls are comparatively spare, without an onboard mixer, app control or general-purpose parametric EQ.

Frequency Response

How the KV2 Audio EX12 measures across the audible range. A flatter listening window (the sound arriving straight at you) is more neutral: peaks sound forward or harsh, dips sound recessed. The estimated in-room response adds what a typical room does, and there a gentle, even tilt down toward the treble is ideal. Both curves are shifted so their 300 Hz to 3 kHz average sits at 0 dB.

EQ for a Neutral Response

Flattens the measured listening window from the KV2 Audio EX12's own bass extension up to 16 kHz. Set a preamp of -1.2 dB, then add these filters to any parametric equalizer in the signal path: the speaker's app or DSP if it has parametric EQ, a miniDSP, Equalizer APO or Wavelet. Boosts are kept to 3 dB, and EQ cannot fix how evenly the speaker spreads sound off-axis, which is why some speakers gain more than others. Predicted preference score with this EQ: 4.5, up from 4.2 (7.0 with an ideal subwoofer, up from 6.6). Calculated by Speaker Ranking from the spinorama measurements above.
