A powered speaker ” 4305P ” has been added to JBL’s traditional studio monitor series. It is an all-in-one speaker that matches modern usage with network connection via Wi-Fi and LAN terminals, Bluetooth wireless, and a wealth of external inputs typical of monitor speakers.
I immediately borrowed a sample and set up JBL “4305P” at home. Ah, I’m sure I’m not the only one who gets excited just by looking at this appearance, the speaker shape that uses JBL’s traditional HDI (High Definition Imaging) X-wave guide horn technology.
Even so, the JBL “4305P” is by no means a huge speaker. As you can see from the photo below, the “4305P” has a pretty cute size for a JBL monitor speaker. The body size is 210 (width) x 336 (height) x 235 (depth) mm and weighs 6.6 kg. Affordable, home-sized powered monitor speakers.
The built-in amplifier is a total of 300W, equipped with a 33mm diameter pulp cone woofer “JW130P-4”, a 25mm diameter ring compression driver “2410H-“, and an HDI horn. The digital system is also very rich, with a built-in DAC that supports up to 192kHz / 24bit, and supports Wi-Fi, Bluetooth, USB-B and optical digital input. In addition, Airplay2 and Chromecast are fully equipped, XLR / 6.3 mm phone (PHONE) terminal, 3.5 mm mini terminal and analog input are prepared, so it’s amazing. By the way, JBL “4305P” also comes with a dedicated remote control. This remote control has a Bluetooth connection, and it is quite convenient that it can be operated regardless of the position or orientation of the speaker.
After that, I will proceed with the setup according to the setup procedure in the attached manual … If you proceed according to the procedure, the JBL “4305P” will connect to Wi-Fi through the iPhone’s “AirPlay speaker” or the “Google Home” application. Nowadays, it’s natural to connect to Wi-Fi even with powered monitor speakers.
Once the Wi-Fi connection is complete, you can freely stream music from your smartphone. Both AirPlay2 and Chromecast are supported, so hardware doesn’t matter. It also supports Roon Ready and MQA.
According to the attached manual, the ideal speaker placement for the JBL “4305P” is an isosceles triangle tilted inward at an angle of 30 degrees, which is the best listening position. Don’t forget to set the bass contour on the back to -3dB if you’re installing near a wall or in a rack. As a point of caution, I would like to recommend that the JBL “4305P” be installed at a height that is firmly aligned with the ears.
When I played Hikaru Utada’s “Anata” on my iPhone with Apple Music, I was able to enjoy a clear stereo image with two speakers and a high-resolution sound with plenty of room. Although it is called a monitor, the point of the JBL “4305P” is the room and richness of the bass that comes from the size of the box. The singing voice is a JBL orthodox style with sharp and passionate strength. BTS’s “Dynamite” has a sharp singing voice, and it’s very pleasant to hear that the bass is completely controlled so that it doesn’t go too far. Even the bass of Ed Sheeran’s “Shivers” is irresistibly good. By the way, in wireless playback, Chromecast, which can be used on Android smartphones, had higher sound quality than playback with AirPlay2.
I think that there are many people who want to combine the JBL “4305P” with a PC and use it for desktop audio, so this time I tried connecting the MacBook Air directly with a USB Type-C to USB B cable, but high-resolution playback is possible with Apple Music. It was confirmed that The sound of the USB connection is completely different from that of Wi-Fi, and the sound is sharper and more information-oriented, allowing you to enjoy higher-quality listening.
When it comes to music listening sources, I think there are many Wi-Fi and USB connections these days, but I also tried connecting to a TV as a way to use the optical digital input terminal and analog terminal of JBL “4305P”.
When I connect the JBL “4305P” and the TVS REGZA “X9400” series with optical digital, specify the format as PCM and output it… even the sound of simple terrestrial digital broadcasting sounds surprisingly good. The texture of the voice and the amount of information appear linearly. It seems that the optical digital input has the best sound. Although it is a stereo speaker, the scale of the sound is outstanding even when listening to movies on Netflix. It eliminates the presence of speakers and creates a well-made stereo space.
However, there were some problems in using the JBL “4305P” as a TV speaker. First of all, since optical digital does not have a mechanism to adjust the volume at the time of output, operation on the JBL “4305P” side is essential. In addition, the JBL “4305P” will auto standby in 10 minutes, and the USB terminal and optical digital terminal are not covered by the automatic return function, so you must manually turn on the power. Analog connection with a 3.5mm mini terminal solves both volume adjustment and standby return, but the sound is thinner than digital connection, and the sound quality is not exactly the same. It’s not that you can’t use it on a TV, but it seems better to use the optical digital or analog input in combination with a Hi-Fi audio device.
Another thing, JBL “4305P” is convenient because it supports a wide variety of connection methods, but it does not have an automatic input switching function, so it is a little inconvenient when using multiple sources. Only Wi-Fi playback can be switched by hijacking other inputs, but it should be noted that when using other terminals together, the remote control is placed at hand and operated.
