#2 L-Acoustics 108P: $7,400 Discontinued eBay
Pros: A compact powered 8 inch coaxial PA speaker with extremely accurate sound, now discontinued but worth buying used. Medium-quality vendor Spinorama data produces a 7.32 ideal-subwoofer preference score, one of the strongest results in this entire family of rankings, with 61Hz bass extension from a compact 8-inch coaxial cabinet. Measured bass extension of 71Hz (-3dB).
Cons: This discontinued cabinet is difficult to source and lacks modern networking or an onboard mixer. Its ranking reflects acoustic performance rather than present-day value or ownership convenience.

Frequency Response
How the L-Acoustics 108P 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.
