Brand: LD Systems
#43 LD Systems Stinger 15-A-G3: $1,044.00 Amazon $1,044.00 eBay
Same family: the LD Systems Stinger 8-A-G3 (smaller model, rated 3.7/5), the LD Systems Stinger 28-A-G3 (smaller model, rated 3.5/5), the LD Systems Stinger 10-A-G3 (smaller model, rated 4.1/5) and the LD Systems Stinger 12 A G3 (smaller model, rated 3.5/5).
Pros: An affordable powered 15 inch PA speaker with two mic/line inputs and unusually deep bass reach for its price class. Medium-quality vendor data shows a 4.10 ideal-subwoofer preference score with 39Hz measured extension, the deepest bass reach of any RCF-priced alternative in this tier, at an affordable price for a 15-inch active box. Measured bass extension of 41.2Hz (-3dB).
Cons: The measured preference score is modest, and its 90° x 50° horn is narrower than several higher-scoring competitors. At 26.8kg it is one of the heavier budget-tier boxes here.

Frequency Response
How the LD Systems Stinger 15-A-G3 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 LD Systems Stinger 15-A-G3's own bass extension up to 16 kHz. Set a preamp of -2.7 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: 0.5, up from 2.2 (5.9 with an ideal subwoofer, up from 4.1). Calculated by Speaker Ranking from the spinorama measurements above.
| Filter | Frequency | Gain | Q |
|---|---|---|---|
| High shelf | 8,000 Hz | -1.7 dB | 0.70 |
| Peak | 65 Hz | -10.0 dB | 0.90 |
