JBL 708P Bi-Amplified Master Reference Studio Monitor

JBL 708P Studio Monitor – Bi-Amplified Master Reference for Critical Listening

The JBL 708P Studio Monitor is an 8-inch bi-amplified master reference monitor built for music recording, film post-production and broadcast work where accuracy cannot be compromised. It pairs JBL’s patented Image Control Waveguide with next-generation driver technology and a powerful built-in DSP, so what you hear at the mix position is what your audience will hear everywhere else. Each JBL 708P Studio Monitor is self-powered, with a dedicated 250-watt amplifier for the high-frequency driver and another 250-watt amplifier for the low-frequency driver, giving the monitor the headroom to reproduce sudden dynamic peaks cleanly.

Why Choose the JBL 708P Studio Monitor?

Reference monitors exist to tell the truth, and the JBL 708P Studio Monitor is designed to do exactly that across a wide range of rooms. Its 2409H high-frequency compression driver uses a low-mass annular diaphragm that stays smooth and detailed beyond 36 kHz, while the 728G low-frequency transducer delivers deep, controlled bass below 35 Hz with 14 mm of peak-to-peak excursion. The Image Control Waveguide produces a wide, stable sweet spot, so the stereo image stays locked even when you move slightly off centre. Onboard room equalisation, delay and presets let you tune the monitor to your room instead of fighting it, and the digital AES3 input accepts sample rates up to 192 kHz for a clean, fully digital signal path from your interface or console.

Key Features

• Bi-amplified 500-watt Class-D power: a dedicated 250-watt amplifier for each driver keeps highs and lows clean at any level.
• Image Control Waveguide: JBL’s patented waveguide delivers a wide sweet spot with precise imaging and neutral response.
• 2409H and 728G drivers: the high-frequency compression driver extends beyond 36 kHz and the 8-inch low-frequency transducer reaches below 35 Hz.
• Onboard DSP with Room EQ: 12 bands of Room EQ, 8 bands of User EQ, 6 factory presets and 6 user-defined presets, plus room and AV sync delay.
• Analogue and digital inputs: a balanced XLR-1/4-inch combination analogue input plus an XLR AES3 digital input with pass-through, and an RJ-45 connection for Harman HiQnet control.
• Built for the studio: a rigid birch plywood enclosure with top, bottom and rear mounting points, and a rear-panel LCD with multi-function controls.

Best Suited For

The JBL 708P Studio Monitor suits recording and mixing engineers, mastering rooms, film and television post-production suites, broadcast facilities and serious project studios. It is equally at home as a main nearfield pair in a small control room or as part of a larger multi-channel monitoring setup, and it can be placed behind a perforated cinema screen where that is required. If your work depends on hearing exactly what is in the recording, this monitor is built for that job.

Setup and Connection Guide

Place a pair of JBL 708P Studio Monitor speakers on sturdy stands or a console meter bridge, angled toward the listening position so the tweeters sit at ear height and the two monitors form an equilateral triangle with your head. Connect your audio interface or monitor controller to the balanced XLR-1/4-inch analogue input, or use the XLR AES3 digital input for a fully digital chain, with the pass-through feeding a second monitor. Use the rear-panel LCD and multi-function controls to set input sensitivity and trim, then run the Room EQ and delay settings to suit your room. Leave space behind the cabinet for the rear port to breathe, and keep the monitor away from untreated corners if you want the tightest low end.

Frequently Asked Questions

Is the JBL 708P Studio Monitor self-powered?

Yes. The JBL 708P Studio Monitor is bi-amplified, with a 250-watt Class-D amplifier for the high-frequency driver and a separate 250-watt amplifier for the low-frequency driver, so it needs only a line-level or digital audio signal and mains power.

What is the difference between the JBL 708P and the smaller JBL 705P?

The JBL 708P uses an 8-inch 728G low-frequency transducer and a larger cabinet, giving it deeper bass extension and higher output than the 5-inch JBL 705P. Both share the same Image Control Waveguide design and DSP platform, so the choice comes down to room size and how much low-frequency headroom your work needs.

Can the JBL 708P Studio Monitor be used with a subwoofer?

Yes. The monitor’s balanced analogue output and digital pass-through make it straightforward to integrate a subwoofer, and the onboard delay and EQ controls help you align the subwoofer with the monitors at the listening position.
