#50 Martin Audio XP15: $1,950 eBay
Same family: the Martin Audio XP12 (smaller model, rated 3.5/5).
Pros: A powered 15 inch PA speaker with a rotatable horn, two combo inputs and fairly deep bass for gigs and events. Medium-quality vendor data returns a 4.71 ideal-subwoofer preference score with 48Hz measured extension, extending the Martin Audio XP12’s rotatable horn and Class-D amplification to a 15-inch cabinet. Measured bass extension of 54.5Hz (-3dB).
Cons: Martin Audio has a smaller North American dealer network than JBL, Yamaha or QSC, and pricing is not yet well established for this model.

Frequency Response
How the Martin Audio XP15 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 Martin Audio XP15's own bass extension up to 16 kHz. Set a preamp of -2.6 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: 3.2, up from 2.4 (5.5 with an ideal subwoofer, up from 4.7). Calculated by Speaker Ranking from the spinorama measurements above.
| Filter | Frequency | Gain | Q |
|---|---|---|---|
| High shelf | 8,000 Hz | -0.4 dB | 0.70 |
| Peak | 99 Hz | -5.7 dB | 1.13 |
| Peak | 673 Hz | -1.1 dB | 1.27 |
