#7 HK Audio LINEAR 7 115 FA: $1,999.00 B&H Photo Video $1,999.00 eBay
Same family: the HK Audio LINEAR 7 110 XA (smaller model, rated 4.2/5), the HK Audio LINEAR 7 112 FA (smaller model, rated 3.8/5) and the HK Audio LINEAR 7 112 XA (smaller model, rated 4/5).
Pros: A powered 15 inch PA speaker with good sound, network audio, detailed EQ and a rotatable horn for professional systems. High-quality vendor data returns a 6.03 ideal-subwoofer preference score with 60Hz measured extension. MILAN/AVB networking, a 10-band parametric EQ and a rotatable constant-directivity horn make it a systems-oriented choice for professional deployment. Measured bass extension of 60Hz (-3dB).
Cons: At 32kg this is a heavy 15-inch cabinet, and buyers who do not need networked audio may find comparable performance in simpler mainstream models. The 60° x 40° pattern is narrower than several rivals.

Frequency Response
How the HK Audio LINEAR 7 115 FA 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 7 115 FA's own bass extension up to 16 kHz. Set a preamp of -1.6 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: 4.2, up from 3.4 (6.8 with an ideal subwoofer, up from 6.0). Calculated by Speaker Ranking from the spinorama measurements above.
| Filter | Frequency | Gain | Q |
|---|---|---|---|
| High shelf | 8,000 Hz | -0.7 dB | 0.70 |
| Peak | 602 Hz | -1.9 dB | 4.00 |
| Peak | 1,916 Hz | +1.7 dB | 4.00 |
| Peak | 6,697 Hz | -1.4 dB | 0.80 |
