{"product_id":"jbl-308-mkiii-438690","title":"308 MKIII","description":"\u003ch3\u003eAn 8-inch reference from the JBL 3 MkII series\u003c\/h3\u003e\u003cp\u003eThe JBL 308P MkII is part of the 3 MkII series, a range of nearfield monitors designed to provide reliable mixing tools for home studios, production control rooms and modern creative spaces. This MkII version incorporates the acoustic principles developed for the brand’s high-end professional monitors, including the Image Control waveguide derived from the JBL 7 and M2 series.\u003c\/p\u003e\u003cp\u003eCompared with previous generations, this evolution refines the transducers’ response, improves linearity and introduces the \u003cstrong\u003eBoundary EQ\u003c\/strong\u003e control. This helps compensate for excess bass caused by placing the monitor too close to a wall, corner or work surface. It is a practical improvement for maintaining consistent mixing decisions in an untreated or small studio.\u003c\/p\u003e\u003ch3\u003eA nearfield monitor for mixing, producing and critical listening\u003c\/h3\u003e\u003cp\u003eWith its 203 mm woofer, the JBL 308P MkII is particularly well suited to producers looking for extended low-frequency response without systematically relying on a subwoofer. Kick drums, electric bass, sub-bass, synthesizers and cinematic effects become more clearly defined while remaining integrated into the overall balance of the mix.\u003c\/p\u003e\u003cp\u003eIt will naturally fit into a serious home studio, a post-production control room, a composition setup or a DJing space requiring analytical monitoring. Its 112 dB SPL peak level also makes it possible to work at a comfortable volume in a medium-sized room, provided it is positioned in an equilateral triangle with the listening position.\u003c\/p\u003e\u003cp\u003eSold individually, this active loudspeaker is intended to be paired with a second 308P MkII to create a stereo system. It can also be integrated into an immersive or multichannel setup thanks to its consistent reproduction and controlled directivity.\u003c\/p\u003e\u003ch3\u003eWide, adjustable and precise monitoring\u003c\/h3\u003e\u003ch4\u003eImage Control waveguide: a more generous sweet spot\u003c\/h4\u003e\u003cp\u003eThe Image Control waveguide optimizes the dispersion of the 25 mm soft-dome tweeter. The soundstage remains precise, with clearer placement of vocals, reverbs and panned instruments. Its 120-degree horizontal and 90-degree vertical cover widens the useful listening area, which is a valuable advantage during long sessions, mix comparisons or two-person work in front of the console.\u003c\/p\u003e\u003ch4\u003eDedicated Class D bi-amplification for each frequency range\u003c\/h4\u003e\u003cp\u003eThe 308P MkII features two 56 W Class D amplifiers, delivering 112 W in total. The woofer and tweeter therefore each have their own dedicated amplification, providing better control of transients and more responsive reproduction. The fourth-order 1,800 Hz Linkwitz-Riley acoustic crossover ensures a coherent transition between the two loudspeakers.\u003c\/p\u003e\u003cp\u003eThe frequency response extends down to 45 Hz within the +\/- 3 dB range, with an advertised extension down to 37 Hz at -10 dB. This low-end foundation makes it easier to control bass energy and identify resonances that could compromise the mix’s translation on other monitoring systems.\u003c\/p\u003e\u003ch4\u003ePractical studio adjustment options\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003eBoundary EQ\u003c\/strong\u003e selector operates on the low frequencies around 50 Hz and offers three positions: 0 dB, -1.5 dB and -3 dB. It helps limit bass build-up when the monitor is placed close to a wall. The \u003cstrong\u003eHF Trim\u003c\/strong\u003e control, available at -2 dB, 0 dB and +2 dB, adjusts the high-frequency brightness according to the room’s acoustics or listening preferences.\u003c\/p\u003e\u003cp\u003eThe balanced connectivity combines an XLR input and a 6.35 mm TRS jack input. The +4 dBu or -10 dBV sensitivity selector makes it easy to integrate the JBL 308P MkII with professional studio equipment as well as more consumer-oriented audio gear. A rear-panel volume control completes the setup, allowing precise gain adjustment for each loudspeaker.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical
