JBL 306P MKII Reviews

Very good for my current needs

By Thomas
Rated 4 out of 5
Date: 2026-05-17

I've been looking for new monitors for sometime, having read quite a bit on ASR about how DSP technology has improved studio monitor design in the last decade. My previous monitors were mid-level- not cheap, and purchased for the mid-field in a room I no longer have. I have been arm-wrestling with them since then. Great, but too big for my new room. I wanted a solid 6" near-field choice with nice bass extension, and settled on these to try. Size, price, specs, reviews, manufacturer- everything lined up. I figured if I liked them well enough, I'd spring for something in the mid-level price range again, perhaps the 7 series. I may not have to. The 306Ps are very, very good monitors for my needs in post and music. I usually don't prefer speakers with rear-firing ports- rather, front facing ports or sealed enclosures, just a preference- so I didn't expect them to suit me. But they do. Things have changed, I think for the better. I may not have to look for a mid/high-end monitor now, but I do like speaker shopping, so maybe down the road...

Impressive build and sound quality.

I use a pair of JBL 306P MkII's for studio monitors and for music playback, song accompaniment during guitar practice and pleasure listening. Really, for a set of reasonably priced powered monitors, they sound fantastic. I run them from my PC through a DAC directly to each speaker. Impressed by the sound and the build quality. Purchased and shipped directly from JBL. Great experience. Would buy again.

How do these speakers sound without the subwoofer? Asking for video production.
Asked by: Andrew
The JBL 306P MkII Powered 6.5" Two-Way Studio Monitors are very popular monitors that are commonly used for recording and video production without a subwoofer. The 306P MkII includes a 6.5" woofer and 1" tweeter, and has a frequency range of 39 Hz to 24 kHz (at -10 dB). If your audio has a lot of content in the frequency range below 39 Hz, then you may want to use a subwoofer along with the studio monitors.

Can you buy a single spearker as a center channel?
Asked by: Michael
You could use it as a center channel in a compatible surround mixing set up, but you would not be able to connect it to a home AV receiver for the purpose of watching movies.

What monitors is this compatible with?
Asked by: Bradley
This kit consists of two studio monitors, which can be used on their own for mixing in a studio or home-studio setting. It is always best to use the same model if you are mixing in surround sound. JBL LSR310S 200W Powered Subwoofer B&H # JBLSR310S is the corresponding subwoofer for this JBL series of monitors.

question

Can these speakers be daisy chained for multiple surround sound experience. I only see (2) inputs on the back
Asked by: Matt H.
No, for that you would need analog line outs which they don't have.
