#6 JBL PRX908: $699.00 Amazon $699.00 B&H Photo Video $699.00 Guitar Center $699.00 eBay

Same family: the JBL PRX912 (larger model, rated 4.3/5) and the JBL PRX915 (larger model, rated 3.9/5).

Pros: A compact powered 8 inch PA speaker with well balanced sound, Bluetooth app control and feedback suppression for gigs and monitors. High-quality vendor data shows a 5.69 ideal-subwoofer preference score with 58Hz measured extension, backed by JBL’s extensive service network. A 12-band parametric EQ with dbx DriveRack feedback suppression and BLE app control carry over the PRX900 series’ engineering into an 8-inch cabinet. Measured bass extension of 63Hz (-3dB).

Cons: Its 126dB peak claim is modest for a main speaker, so pairing with a subwoofer matters more here than with the larger PRX modules.

Frequency Response

How the JBL PRX908 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.

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.
