JBL 305P MKII vs JBL 705P

Last updated: August 18, 2026

Short answer: the JBL 305P MKII. It ranks #9 of 42 powered bookshelf speakers by sound quality at $319; the JBL 705P ranks #18 and costs $1998, so there is not much of a tradeoff to weigh.

On the JBL 305P MKII side: A fantastic value in studio monitors. Set against that: Possible slight hissing from the amps at low levels.

The case for the JBL 705P: CEA2034 spinorama shows flat response with excellent directivity, similar to its larger 708P sibling. The tradeoff: A cancellation around 750Hz (likely port-related) and a bit of boosted response at the 1.75kHz crossover show up in the on-axis curve.

Buy the JBL 305P MKII. It ranks higher for sound quality than the JBL 705P and costs less, so there is no real case for the other one.

JBL 305P MKII: $319.00 Amazon

JBL 305P MKII ranking card

Pros: A fantastic value in studio monitors. Extremely close to the Focal Alpha 50 EVO, almost indistinguishable. Surprisingly deep and wide soundstage. Good horizontal dispersion (~70 degrees). Has a proper limiter that controls output cleanly rather than crudely cutting bass, and holds up well under sustained loud playback with minimal thermal compression.

Cons: Possible slight hissing from the amps at low levels. Rear ported, can be an issue close to walls. A port resonance around 1.6kHz is audible and distracting on some tracks. Midrange is somewhat scooped rather than flat for a studio monitor, and treble runs about 1.5dB hot - Erin’s Audio Corner recommends using the -2dB treble shelf switch. Vertical dispersion narrows around the crossover, so try to stay within about 10 degrees of the tweeter axis.

JBL 705P: $1998 Bhphotovideo

JBL 705P ranking card

Pros: CEA2034 spinorama shows flat response with excellent directivity, similar to its larger 708P sibling. Bi-amplified 500W design (250W woofer, 250W compression driver) into a 5” woofer and JBL’s 2409H compression tweeter.

Cons: A cancellation around 750Hz (likely port-related) and a bit of boosted response at the 1.75kHz crossover show up in the on-axis curve. Sits right around the ear’s most sensitive hearing range near 100Hz, so that region is partially audible even at modest levels.
