The short version

The 305P MkII is a 5-inch powered two-way studio monitor with a long-throw woofer, 1-inch neodymium tweeter and JBL's patented Image Control Waveguide, driven by 82 W of Class-D amplification with XLR and TRS inputs. JBL lists a 43 Hz to 24 kHz response and boundary EQ for placement near walls. It suits home studios and near-field desks, and JBL has announced a 305P MkIII for US availability in January 2027.

Pros

  • Image Control Waveguide for a wide sweet spot, per JBL
  • Long-throw 5-inch woofer and 1-inch neodymium tweeter
  • Balanced XLR and 1/4-inch TRS inputs
  • HF trim and boundary EQ for room placement

Cons

  • No RCA, 3.5 mm, Bluetooth or USB inputs, so consumer sources need adapters
  • JBL's page describes one monitor, so confirm whether a listing is per unit or per pair
  • A 305P MkIII successor is announced for US availability in early 2027

Best for

  • Home studios with an audio interface
  • Near-field mixing and production

Common questions

Do I need an audio interface for the 305P MkII?

JBL lists only balanced XLR and 1/4-inch TRS inputs, so an audio interface is the most common source; a PC without one needs an adapter cable.

Is the 305P MkII sold as a pair?

JBL's product page describes a single powered 5-inch studio monitor, and retail listings should be checked to confirm whether a price is per unit or per pair.

Has it been replaced?

JBL has announced a 305P MkIII for availability in the US and Canada on January 7, 2027. The MkII remains on JBL's site and is the model covered here.
