JBL 306P MKII Reviews

Fantastic monitor for the money

By Simon
Rated 5 out of 5
Date: 2025-06-10

After using 4 pairs of these for a museum installation (paired with the 10 subwoofers & 5 speakers), I decided it was time to upgrade my home edit station sound as well. Coming from a very budget mackie speaker set up it has a lot more range with defined low & high end that was missing.

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.

Is there an EU power cord version available? One for use in Germany?
Asked by: Ryan
It supports both US and European voltages so all you would need is a standard US to German plug adapter not a voltage convertor. Also, the end which goes into the speaker is the standard computer power cable format so a cable should be easy to find.

Do I need anything else to connect to my Mac Studio? Cables etc
Asked by: Dan
Aside from the items included in this JBL 305P MkII Studio Monitor Kit, the only other item you will need is a short standard stereo aux cable such as the Pearstone Stereo Mini Male to Stereo Mini Male Cable - Black, 3' (B&amp;H # PEMMSA103B) which will be used to connect the computer's 3.5mm audio output (headphone jack) to the 3.5mm TRS input on the Senal PMC-II Passive Monitor Controller. If you are using a USB audio interface and want to connect the PMC-II and JBL speakers to the interface, you can use the audio output(s) from the interface and connect them to the right/left XLR-1/4&quot; combo jack inputs OR to the 3.5mm input on the PMC-II Monitor Controller using the appropriate cables (not included).

How do these speakers sound without the subwoofer? Asking for video production.
Asked by: Andrew
The JBL 306P MkII Powered 6.5&quot; 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&quot; woofer and 1&quot; 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.

Can the amplifier be bypassed to use as passive speakers?
Asked by: Anonymous
This is an active speaker, with the amplifiers built in, so it would not be used as a passive speaker. JBL LSR708i 8&quot; Master Reference Monitor (Single), BH #JBLSR708I would be a very god quality passive reference monitor to consider.

Can you add a subwoofer?

Can you add a subwoofer?
Asked by: Steven
Yes, a subwoofer such as the JBL LSR310S 200W Powered 10&quot; Subwoofer(BH #JBLSR310S) is a great pairing for the JBL 308P MkII Powered 8&quot; Two-Way Studio Monitors. You would feed the subwoofer from your main output signal, then feed the monitors from the subwoofer outputs. Link to LSR310S here: https://bhpho.to/3DCLlTY
