#43 HK Audio LINEAR 5 112 XA: $800 Discontinued eBay
Newer model: the HK Audio Linear 5 MK2 112 XA, ranked higher, estimated 3.7/5, released 2023. See every HK Audio Linear 5 generation.
Pros: A compact powered 12 inch PA box that doubles as a floor monitor, with a rotatable horn that throws sound over long distances. Its high-quality vendor data returns a 5.21 ideal-subwoofer preference score, and the compact monitor-capable enclosure reaches a claimed 136dB peak. The rotatable 60° x 40° horn helps concentrate output over longer distances. Measured bass extension of 95Hz (-3dB).
Cons: Measured bass extension is only about 87Hz, so this XA model is best treated as a mid/high cabinet over subwoofers rather than a stand-alone full-range main. It is an older discontinued generation with limited onboard user processing.
Is the HK Audio LINEAR 5 112 XA right for you?
Skip it if
- you will not add a subwoofer: bass rolls off below about 95 Hz.
- you want to buy it new: it is discontinued.

Frequency Response
How the HK Audio LINEAR 5 112 XA 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.
Measurement data: spinorama.org, measured by the manufacturer.
EQ for a Neutral Response
Flattens the measured listening window from the HK Audio LINEAR 5 112 XA's own bass extension up to 16 kHz. Set a preamp of -2.9 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: 2.8, up from 1.8 (6.2 with an ideal subwoofer, up from 5.2). Calculated by Speaker Ranking from the spinorama measurements above.
| Filter | Frequency | Gain | Q |
|---|---|---|---|
| High shelf | 8,000 Hz | -1.2 dB | 0.70 |
| Peak | 185 Hz | -4.9 dB | 1.16 |
| Peak | 376 Hz | -1.8 dB | 3.11 |
| Peak | 1,235 Hz | +3.0 dB | 3.41 |
| Peak | 11,404 Hz | -1.3 dB | 0.50 |
