#14 JBL 305P MKII: $289.00 per pair Amazon eBay

Older model: the JBL LSR305 (ranked lower, rated 4.2/5).

Larger models: the JBL 306P MKII (rated 4.1/5) and the JBL 308P MKII (rated 4.4/5).

Pros: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Broad horizontal coverage and reasonably smooth reflected sound support stable imaging across a desk. The existing review reports effective limiting and little sustained thermal compression, making it a strong budget-monitor option rather than just a speaker with a promising frequency curve. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 91.1dB.

Cons: The 3.3dB midrange span and rising response show it is not perfectly neutral. A port-related feature around 1.6kHz and some excess treble can be audible; the review recommends the treble-trim switch. Vertical crossover interference makes ear height important. Amplifier hiss may matter in very quiet nearfield use, and rear-port placement needs room-boundary adjustment.

How it compares: Just above it: Klipsch The Fives - $410 more, 79W more output power. Just below it: KEF LS50 Wireless II - $2710 more, 199W more output power.
