Brand: Axiom
#18 Axiom ED150A: $1,990 eBay
Same family: the Axiom ED60P (smaller model, rated 3.3/5), the Axiom ED80P (smaller model, rated 3.4/5) and the Axiom ED120A (smaller model, rated 4/5).
Pros: A powered 15 inch PA speaker with good sound, deep bass and an asymmetric pattern that spreads sound evenly over an audience. High-quality vendor data returns a 5.36 ideal-subwoofer preference score with 47Hz measured extension, matching the well-regarded Axiom ED120A’s asymmetric-coverage design in a 15-inch cabinet. Measured bass extension of 54.5Hz (-3dB).
Cons: Axiom has a much smaller North American dealer and service network than JBL, Yamaha or QSC, and detailed coverage/weight figures were not confirmed in local data.

Frequency Response
How the Axiom ED150A 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 Axiom ED150A's own bass extension up to 16 kHz. Set a preamp of -3.2 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: 3.4, up from 3.1 (5.7 with an ideal subwoofer, up from 5.4). Calculated by Speaker Ranking from the spinorama measurements above.
| Filter | Frequency | Gain | Q |
|---|---|---|---|
| High shelf | 8,000 Hz | +0.3 dB | 0.70 |
| Peak | 307 Hz | -1.7 dB | 0.50 |
| Peak | 1,684 Hz | +2.0 dB | 1.95 |
| Peak | 3,119 Hz | +1.6 dB | 4.00 |
