#24 JBL 308P MKII: $498 Bhphotovideo

Pros: CEA2034 spinorama shows an essentially flat on-axis response from 45Hz to above 15kHz, with almost no directivity error. Dual 56W Class D amps drive an 8” woofer and 1” tweeter with a smooth, imperceptible crossover transition. Excellent value at $498 per pair.

Cons: A resonance shows up around 18kHz and a slight dip around 1.4kHz. An electronic limiter creates measurable anomalies around 96dB, and maximum clean output tops out around 105dB SPL before heavy limiting kicks in. Some audible tweeter hiss at close range.

How it compares: Just above it: Yamaha HS8 - $180 more, 8W more output power. Just below it: Adam Audio T8V - $148 cheaper, 22W less output power.
