About the JBL 4305P Studio Monitors

Hi-fi powered speakers

JBL's 4305P Studio Monitors give you hi-fi sound in a streamlined powered speaker pair. It's a nice reminder of JBL's heritage in the control rooms of many a high-end recording studio.
JBL 4305P Studio Monitor

The 4305P Studio Monitor wireless speaker system from JBL has Wi-Fi and Bluetooth, plus digital and analog inputs (shown in black).

Hi-fi powered speakers

JBL's 4305P Studio Monitors give you hi-fi sound in a streamlined powered speaker pair. It's a nice reminder of JBL's heritage in the control rooms of many a high-end recording studio.

You can use these speakers in your studio for accurate audio reproduction. Or enjoy high-quality home listening with your favorite wireless streaming options. They also include plenty of wired digital and analog inputs.

With their furniture-grade wood veneer finish and retro-styling, they'll look great wherever you place them. And they'll sound great too, since they're front ported and designed for both near- and far-field listening.

Formidable power and horn-loaded tweeters

The 4305P's built-in Class D power includes four discrete amplifiers — one for each driver. It sends 25 watts each to the horn-loaded tweeters and 125 watts each to the 5-1/4" woofers. That eliminates the need for passive crossovers and ensures a tailored response for agile, detailed, and muscular sound.

My listening impressions of the JBL 4305P Studio Monitors

After many years of hearing JBLs in action at concerts in P.A. systems and guitar amps, I know what I love about the JBL sound. When I pulled the 4305P system out of its box for some trial listening, I was hoping to hear some of that.

And they delivered in a bigger way than seems possible from this relatively compact bookshelf speaker system. Paul Desmond's saxophone on “I'm Old Fashioned” from the Pure Desmond album pours like honey out of the speakers' horns. The sound has a lively, spontaneous quality that works really well with the generous drench of plate reverb on Desmond's sax.

They also nicely accentuated that track's mid and bass frequencies, delivering an energetic rendering of the textures and tones of Ed Bickert's guitar and Ron Carter's double-bass. But the low end really came to life on the Bee Gees' “Night Fever.” The 4305P's handling of that track's grandiose verses had a get-up-and-go — and no-joke bass — that took me back to the skating rink circa ‘78.

The relatively modern retro-disco MGMT track “Electric Feel” owes a debt to Bee Gees stuff from the that era. But it's got a sweaty-DIY-dance-party edge to it that came through this system in full force. The propulsive mids and lows grab you and pull you into the music, and the synth sparkles get stuck in your hair. 

I streamed to the 4305P via Bluetooth, Wi-Fi, and with my Bluesound Node connected to the TRS input. Listening carefully, I could hear the increase in sound quality sequentially across those formats. But the system retained that assertive real-time character, like the next best thing to seeing a band live.

Control in your hands

Front-panel and remote controls let you power on and off, switch sources, control playback, and more. The free MusicLife app for Apple® and Android™ devices gives you another control option.

But with Bluetooth, Roon, Chromecast built-in, and Apple AirPlay 2 all native to the 4305P, you can do pretty much everything from within your smartphone's streaming apps.

Flexible connections and high-res DAC

You can connect the 4305P to your home network via Wi-Fi or Ethernet. Its combination XLR/TRS input lets you add analog sources with a balanced or unbalanced connection. There's also a 3.5mm analog aux input, plus an optical digital connection. An asynchronous USB input lets you connect a computer and enjoy precise sound with your stored digital music files.

The system's built-in DAC supports high-res audio, and with the primary and secondary speakers connected wirelessly, you'll get 24-bit/96kHz resolution. Use the included Digital Link cable to reach the system's maximum resolution of 24-bit/192kHz.

You can connect a powered subwoofer for more oomph in the low frequencies — and more headroom in the 4305P, since it automatically engages an 80Hz high-pass filter.

JBL 4305P Studio Monitor: The JBL 4305P Studio Monitor speaker system consists of two wireless powered speakers featuring patented JBL transducer & acoustic technologies that render your music with incredible accuracy and powerful dynamics. One of the speakers is the "Primary" speaker, while the other speaker is the "Secondary" speaker. The speakers can be paired together wirelessly or tethered together by the included CAT5e cable. Both speakers feature built-in amplification and require AC power. Either speaker can used as the Left or Right channel. All controls and inputs/outputs are found on the "Primary" speaker.

  • 2-Way Driver Design: Each 4305P Studio Monitor speaker uses a two-way driver design, featuring a 1" compression horn driver and a 5.25" fiber-composite cone woofer for room-filling stereo sound.. The 1" compression driver is mated to a high-definition imaging horn with a dispersion pattern of 90 degrees (h) x 60 degrees (v) for crystal-clear highs and life-like dynamic capabilities. The 5.25" paper-pulp cone woofer features a cast frame and is mated with the speaker enclosure's dual front-firing ports for for accurate, distortion-free bass.
  • Class D Amplification: Each Studio Monitor speaker features built-in, custom-tuned Class D amplification. Each 1" compression horn driver receiver 25 watts of power, while each 5.25" paper-pulp cone woofer receives 125 watts of power for a total system power of 300 watts.
  • Bass Reflex MDF Enclosure: Each speaker employs a bass reflex cabinet with dual front-firing ports that have been precision tuned for greater efficiency, bigger bass response, and low distortion. The speaker enclosure features rigid MDF construction and is finished with a black or walnut furniture-grade wood veneer.

24-Bit/192kHz Hi-Res DAC:  The JBL 4305P Studio Monitor speaker system employs a 24-bit/192kHz high-resolution DAC (digital-to-analog converter) to ensure your favorite music comes across with the highest fidelity. 24-bit/19kHz Hi Res audio is only possible when the 4305P Studio Monitor's Primary and Secondary speaker are tethered with the included 10' CAT5e cable. When operating with a wireless connection between the 4305P Studio Monitor's Primary and Secondary speaker, the system is limited to 24-bit/96kHz audio.

MQA (Master Quality Authenticated): The integration of MQA technology enables you to playback MQA audio files and streams, delivering the sound of the original master recording. MQA is a revolutionary end-to-end technology that captures and delivers master quality audio in a file that's small enough to stream or download. MQA lets you hear your streamed digital music files exactly like the way the artist intended you to hear it when it was approved in the studio.

Asynchronous USB-B: The asynchronous USB-B port allows you to connect a Windows PC (7-up) or Mac (OS X) computer for playback of your stored digital music library on the JBL 4305P Studio Monitor speaker system. Supported music files include MP3, WMA, AAC, AIFF, ALAC, WAV, DSD (to PCM), MQA, and FLAC (up to 24-bit/192kHz). The USB-B port is found on the back of the Primary speaker.

Note: There is also a rear-panel USB-A port for service and firmware purposes only. This USB-A port cannot be used for media playback or charging.

Optical Digital Input: The optical (toslink) digital input supports stereo 2ch PCM audio, up to 24-bit/192kHz. The optical digital input is found on the back of the Primary speaker.

Note: The optical digital input does not support Dolby Digital, DTS, or other multichannel surround formats.

XLR/TRS Combo Input: The JBL 4305P includes an analog XLR-1/4" TRS combo input with selectable input sensitivity for use with balanced and unbalanced analog audio signals. The inclusion of this "prosumer-grade" input provides the option for balanced XLR and 1/4" TRS (tip/ring/sleeve) or unbalanced TS (tip/sleeve) connections, perfect for use in home studio applications. Select the appropriate sensitivity level in support of content / source input (-10dB / High sensitivity mode or +4dB / Low sensitivity mode).

3.5mm Aux Input: The JBL 4305P Studio Monitor speaker system is outfitted with a 3.5mm Aux input that allows connection of an external audio device with a line-level output or headphone out jack. The 3.5mm Aux input is found on the Primary speaker.

Note: The 4305P Studio Monitor system does not offer a Phono input for connecting a turntable. If you want to connect a turntable, you'll need a turntable with a built-in preamp or an external phono preamp. You may also need a stereo minijack-to-RCA adapter, since the 4305P only has a 3.5mm Aux input.

Mono-RCA Sub Out: The JBL 4305P Studio Monitor is equipped with a mono-RCA subwoofer output for connection of a powered subwoofer (sold separately). The mono-RCA subwoofer output is full-range, so your powered subwoofer will need its own built-in low-pass crossover filter. The mono-RCA subwoofer output is found on the Primary speaker.
