#20 JBL 708P: $4000 Bhphotovideo

Pros: CEA2034 spinorama shows extremely good frequency response both on- and off-axis, with excellent horizontal directivity. Bi-amplified 500W design (250W woofer, 250W compression driver) handles an 8” woofer and JBL’s 2409H compression tweeter.

Cons: A port resonance creates a mild rise around 600-900Hz. Vertical dispersion is narrower than horizontal, so staying within a few degrees of the tweeter axis matters. Distortion climbs at 96dB SPL, with the tweeter reaching about 2.5% THD at elevated levels.

How it compares: Just above it: JBL 4329P - $500 more. Just below it: Presonus Eris Studio 8 - $3538 cheaper, 360W less output power.
