Brand: LD Systems
#29 LD Systems DDQ12: $1,170 Discontinued eBay
Same family: the LD Systems DDQ15 (larger model, rated 3.9/5).
Pros: A light, compact 12 inch powered PA top with a plywood cabinet and controlled horn, easy to deploy for professional work. Medium-quality vendor data returns a strong 6.32 ideal-subwoofer preference score and 63Hz bass extension. The lightweight 17kg plywood enclosure and controlled 80° x 50° horn make it easy to deploy as a compact professional top. Measured bass extension of 67Hz (-3dB).
Cons: The discontinued DDQ platform is harder to buy and support than current LD, RCF, JBL or Yamaha ranges. Its controls and connectivity are basic by modern standards, with no app, networking or onboard mixer.

Frequency Response
How the LD Systems DDQ12 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
No EQ preset: the best simple EQ we can fit to these measurements improves the predicted preference score by less than 0.2. The listening window is already close to flat, and what holds the score back, such as narrow ripple in the response or uneven output off-axis, is not something EQ can fix without making it worse elsewhere.
