Brand: FBT
#19 FBT J8A: $800 Discontinued eBay
Pros: A discontinued compact powered 8 inch PA speaker with switchable presets that also works as a floor monitor. Medium-quality vendor data shows a 5.09 ideal-subwoofer preference score with 58Hz measured extension. A bi-amplified 200W/50W Class-D design, a 1-inch compression driver on a 90° x 60° horn and switchable Original/Boost DSP presets pack real flexibility into a compact monitor-capable cabinet. Measured bass extension of 60Hz (-3dB).
Cons: Its 120/128dB SPL claims trail the higher-output actives in this ranking, and it lacks an app or Bluetooth control. Discontinued.

Frequency Response
How the FBT J8A 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.
