Product description

Building on JBL legacy of high-quality sound performance, the 3 series Mk II represents an upgrade of the impressive LSR3 series. These compact, professional quality, powered studio monitors retain the LSR3 series' image control waveguide for incredible detail and imaging, and the broad sweet spot that means you get optimal sound even off-axis. The Mk II series now features updated high-frequency (HF) and low-frequency (LF) transducers, which respectively provide optimized damping for superior transient response and greater linearity that allows impressively deep bass with lower harmonic distortion. Upgrades also include new boundary equalization (EQ), which restores neutral LF response when speakers are placed on the work surface and adjacent walls. Hear for yourself why JBL is legendary in sound performance and quality!

I was wanting to buy some klipsch speakers for my office. I went with JBL due to cost difference and based on positive reviews. I don’t regret going with these and I think I may like these more than the klipsch because have some good punchy bass

Amazing speakers for my pc!! Got these and was happy with the bass but I wanted more so got the LSR10s subwoofer and they're amazing. Running them off a Fiio K3 DAC/AMP and also bought some speaker isolation pads to put underneath them and they tightened up the bass so nice. Really high quality product. Turned my room into a nightclub with some wall sound panels too haha

The JBL 306P work perfectly for me. They are accurate, have plenty of low-end so I don't need a sub-woofer and they pack enough punch to cover pretty much any genre. I also like that they are VERY quiet when idling and they start quietly at power-up too, no thump noises at all. I had a few questions to JBL support, and they got back to me super fast and the guys knew their stuff ! I couldn't be happier with these.

My first experience with studio monitors and I was amazed at the sound quality. I don't think I've ever heard anything that clean and clear. I opted for the 306s over the 305s because everything I've read suggested that 5-inch monitors don't really have any bass, but the 6s don't really seem to have much bass response either. I may just need to get used to them. Entirely possible I'll eventually have to get the LSR310S.

The monitors are large, so be prepared. :)

There's the slightest hiss when you power them up. I think it's more noticeable than other speakers only because they're set up exactly at ear height and at the proper angles. As soon as I start playing any sort of audio through them, I stop noticing the hiss (for the record, my logitech desk speakers have a hiss too, so it's not anything wrong with the JBLs).

I in love and hate with this speakers. I don't think I've owned such realistic and truthfully sounding speakers before, especially at such low price. I'd say this is perhaps the best deal I've ever seen for a pair of speakers. It's madness. I recommend those. Great quality and value for a price.

Dopo aver fatto uno studio sui vari siti specializzati, ho concluso che sono quelle con il miglior rapporto qualità/prezzo. Suonano benissimo e senza alterare il suono, ideali per chi fa produzioni domestiche e da studio. Suoni non impastati e correttamente bilanciate. Assolutamente consigliate.

Ich habe schon mehrere Aktiv Monitore miteinander verglichen, darunter KRK Rokit 5, Adam Audio, sogar Yamaha HS80. Leider haben sie mir alle nicht so richtig gefallen, zwar von der Qualität schon, aber der Sound war nicht so meins. Die JBL wiederum klingen einfach großartig und der Preis ist einfach unschlagbar. Aber hört am besten vorher probe, die Geschmäcker scheinen da sehr unterschiedlich zu sein.

Einziger Haken: es gibt ein deutlich vernehmbares Grundrauschen. Damit muss man in der Preisklasse leben können ..

Reviewed in the United Kingdom on August 17, 2021

This sounds VERY nice. Crisp, clean, balanced, and not ridiculously over-bassed like some speakers. Recommended.

There are some issues.

First, the volume control is firmly notched -- it wants to be set at one discrete volume or another. So you can't do a very linear/analogue positioning to a volume level in-between 5 and 6 (or 5.5 and 6, or whatever it is).

They look... just OK. Very basic studio monitor look, with no frills. Fine for a studio, but not so great if you want to put them in the living room. That said, they don't look as plasticy -- or rather, the plasticyness doesn't stand out so much in a room -- as they do in some photos.

It came with EU wall plugs on the cable, so you'll want to buy an IEC cable with a UK plug, or just a plug if you're up for re-wiring the cable, or an adapter if your studio is a mess of wires anyway ;)

Lastly, the pair I ordered were very poorly packed and arrived in an open box. Thanks, Amazon.
