#2 L-Acoustics 112P: $4,870 Discontinued eBay
Pros: A superb sounding coaxial 12 inch PA monitor with even coverage; now discontinued but worth buying used. Its medium-quality vendor Spinorama data produces the category’s highest ideal-subwoofer preference score at 8.09, with 54Hz bass extension. The coaxial layout gives symmetric 90° coverage and strong feedback resistance for monitor and near-field work. Measured bass extension of 60Hz (-3dB).
Cons: This discontinued 32kg cabinet is difficult to source, very heavy for a portable 12-inch box and lacks modern networking or an onboard mixer. Its ranking reflects acoustic performance rather than present-day value or ownership convenience.
Is the L-Acoustics 112P right for you?
Buy it if
- you want measurably neutral sound (preference score 8.1 with a subwoofer).
Skip it if
- you want to buy it new: it is discontinued.

Frequency Response
How the L-Acoustics 112P 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 L-Acoustics 112P's own bass extension up to 16 kHz. Set a preamp of -2.4 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: 5.8, up from 5.6 (8.3 with an ideal subwoofer, up from 8.1). Calculated by Speaker Ranking from the spinorama measurements above.
| Filter | Frequency | Gain | Q |
|---|---|---|---|
| High shelf | 8,000 Hz | +0.7 dB | 0.70 |
| Peak | 2,519 Hz | +1.5 dB | 4.00 |
| Peak | 10,862 Hz | +1.7 dB | 2.13 |
