Compact near-field monitor with high-end technology

The JBL LSR 305P MkII is an active two-way near-field monitor with an impressive price-to-sound ratio. As the most compact member of the American manufacturer's 3 series, this monitor features some of the most efficient concepts from JBL’s considerably more costly M2 monitors. The tweeter's patented Image Control Waveguide ensures a large sweet spot and an accurate representation of the stereo panorama, while the double-flanged bass reflex channel on the rear panel enables powerful bass reproduction regardless of the size of the housing.

The frequency response of a larger model

Thanks to its special bass reflex technology, the compact JBL LSR 305P MkII can reach bass ranges that other five-inch devices can only dream of. The frequency response starts at a remarkable 43 Hz and extends all the way up to 22 kHz. A high performance and extremely precise transient response are the result of the newly revised driver design. The rear panel includes a set of controls for bass roll-off and high shelf filter which allow you to make adjustments to match the sound of the room. The five-inch woofer and the one-inch tweeter are both fed by separate power amplifiers with an output of 41 watts each.

Stylistically diverse

The JBL LSR 305P MkII brings the advantages of a good frequency response, a large sweet spot, and a clear transient response to all musical genres. No matter if you’re an EDM producer, hip hopper, singer-songwriter, or metalhead, if you're after an inexpensive monitor that just sounds great, the LSR 305P MkII has everything you need. Even in areas which are not exclusively music-related, such as post-production for podcasts or YouTube videos, this speaker offers a reliable basis for assessing your sound.

About JBL

JBL is an American company founded by James B. Lansing in 1946, which first went under the name of Lansing Sound Inc. Following legal disputes with Lansing's previous company, Altec Lansing, Lansing Sound Inc. changed its name first to James B. Lansing Sound Inc., and then finally to JBL in 1949. JBL's current headquarters are based in Los Angeles, USA. The company is well known for its audio system equipment, including loudspeakers and headphones, and is divided into two branches: JBL Consumer, which is dedicated to the consumer sector, and JBL Professional, which is focused on the professional audio sector and offers equipment for studios, live applications, and cinemas. JBL has been a part of Harman International Industries Inc. since 1969, which in 2017 became a subsidiary of the Samsung Group.

In the studio and on the road

The JBL LSR 305P MkII's specifications make it suitable for use in spaces of all sizes, including smaller rooms and conventional bedroom studio setups, which are often prone to problems with bass reproduction. Thanks to its compact dimensions and low weight of just 4.5 kg per speaker, this two-way system is also an excellent choice for mobile recording sessions.

As a owner of the previous LSR305, I bought this second pair blindly.

Sound wise, they are as great as ever and maybe even better. Zero complain here.

There is still the same hiss. Quite annoying, can be reduced by lowering the volume to get the best compromise noise/signal.
An auto standby mode shuts the amp completely after some time so no more hiss when unused. That's better than nothing, but I would have preferred a reduced hiss.

However the real pain with the LSR305P is a new permanent coil whine.
It doesn't come from tweeter nor the woofer. It comes from the back, the power supply to my guess.
It's pretty high pitch and faint so I tried to just ignore it but after three days there is still a few moments of the day when I find this ringing way too annoying. Even at 2 meters away.
Unplugging every electronic device in the room did nothing. The only way to remove that ringing is to power off the speakers.

Excellent value for money
audiouser, 03.01.2020
Excellent value for money, with a strong sound stage and a good amount of bass - not completely flat so perfect for casual listening - music, movies, etc. They also work well in larger rooms as a portable audio system as they're not too heavy so you can carry them around on your shoulder in the Gator G-STUDIOMON1 bag also available here if you don't want to buy a full PA system.

They do have a noticable hiss which is fine in my use case but you will be able to hear it in a smaller room when nothing is playing. If that bothers you seek a different product. The hiss is constant at all volumes. Also worth noting don't try turning these up to 10 and play films through without normalization, if you hit something that peaks the audio output like an explosion the speakers briefly cut off and the driver restarts. 6-7 is the sweet spot for me, but will depend on your audio source.

Build quality is okay but don't expect anything premium, things aren't glued flush for example. These speakers are much more about the sound for the price than overall build quality.

Works well with the JBL LSR310S subwoofer if you want extended bass response (or added earthquakes) in your setup.

Great for the price
epasym, 05.01.2021
As an inexperienced user of such monitors, pretty much my only complaint is the glossy finish on the front that collects too much dust.
It sounds great and is very feature rich for how cheap it is.
However, if you don't have a lot of space you should know that they are much bigger than you'd expect if you have never bought monitors before, and I'm assuming a lot of potential buyers have not.

I use my pair for listening to and mixing music primarily. I have them connected to a scarlett 2i2. At first they sounded extremely bassy, but after a quick look through the manual, I realised all I had to do to fix that was flip a switch on the back, so do read the manual if you don't know what you're doing.
They're very easy to set up, but you will need to have the equipment to connect them to your device, so look up what connections you need and get the proper cables, or you might end up with a big bulky paperweight.
For first time buyers, do keep in mind that you need to buy them individually, meaning if you order one from here, you only get one speaker.

Finally, one thing that annoys me slightly from time to time is the low hum they make when on max volume. I always have them on max volume and control it through my interface, but you can probably just use them differently and not have that problem.

Amazing Studio Monitors
agim lubonja, 24.03.2020
Received today the package from Thomann. Way to enjoy these amazing monitors these sad days of quarantine mostly inside the house. Great package like a rock. Very good quality build as I have checked to watch and listen on YT before I decided to have also these monitors in my room. Connected them to my soundcard through balanced ins and outs. I did optioned for the +2 db in the HF Trim and the sound came in very very good quality and I could not believe to my ears how good is their response to the signal. Also my first thought was to read carefully the instructions and by this, I did not move the Selectable input Sensitivity switch and I left it where it was from the factory, at -10 dbv. The sound came perfect. My soundcard has a +3 dBu max. output level. The JBL switch goes to +4 dBu. For this time I'm running them to -10. The last thing. I have read also the reviews here before I did the purchase and went and became a little hesitant reading about that hizzzz that some people did complain. No sir! They don't hizzz. So glad I did choose JBL. Highly recommend. Thank You!
