Pros and Cons



Primary Features of JBL 305p MK II

Okay let’s star talk about the primary features of the JBL 305p MK II.

  • Let’s start with the weight. The weight of this studio monitor is 10.43 lbs or 4.73 kg only, which is a lighter weight considering other studio monitors. So being lightweight and portable equipment, you can easily move it from one place to another.
  • And to make the weight this low PVC is used as the material to produce it, which also gives it durability. Since PVC can keep it functioning against tear or wear problems, PVC is a nice touch.
  • Regarding the power of the JBL 305p MK II, per driver it possesses 56 watts. An average of 41 watts is demanded by its volume levels. But this studio monitor can provide redundant power, so higher volumes can be easily played. And distortions can be easily avoided by playing it with higher volume levels and the sound will be more precise too.
  • The proven engineering of JBL and using of new technology have made this studio monitor as one of the most competitive monitors in the market, in fact, it has become kind of a pioneer of studio monitors.

And the pricing is not too high either, comparing the price of other available studios on the market, considering that it provides really expert quality and also good clarity and definition.

Key Features

Among the other key features, the JBL 305p MK II has some other great features.

  • It has an image control waveguide that’s fully patented.
  • The device-speaker response of this studio monitor is really fast.
  • It has dual integration and has a fascinating dynamic range of 92 watts.
  • For maintaining the balance between high to low frequency, it has an HF Trim switch.
  • It guarantees that you can use it for years through 100 hours full-power test.
  • And the design of this studio monitor is sleek, which can give be aesthetic for your room, and it can meet your expectations really well.
  • ABS made baffles provide protection to its vital interior and also gives the structure a shiny look.
  • It also has got a magnetic shielding, which prevents damage that can be caused by any kind of magnetic interference and saves the monitor from problems.
  • This studio monitor can be plugged almost anywhere as its input voltage is 100-240 VAC.
  • Ports and flips in the back can help you to adjust the decibel levels of the sound.

And all these features come with a comparatively low price. However, some can find the monitor design a bit bland, and the bass boost feature is not available in this studio monitor.

Image Control Waveguide technology

Like the other 3 series of JBL, an Image Control Waveguide technology has been added to this studio monitor. This technology manipulates the waveform distribution of the monitor, which allows the sound to reach every corner of the room. They have managed to provide such an expensive technology in an affordable studio monitor like the JBL 305p MK II.

Bottom line is, the specs provided by this are so captivating and above average for such an unexpectedly lower price, and also the sound produced by this is really powerful and comes with high clarity and definition.


We talked earlier about the power drivers of the JBL 305p MK II, which have 41 watts, whereas the average of 20 watts per driver is a basic demand for volume levels. Its drivers are amps of Class-D. There are seven different kinds of classes for amplifiers, while class A being the simplest and class G being the most powerful and efficient of them all.

However, Class D is a really good one in power management and in being efficient. And for being more efficient in power management gives the amplifier the scope to be smaller without sacrificing definition and quality. So this studio monitor can produce higher volume levels without being bigger in size. It can also extend the lower frequencies longer for being its cabinets ported. The bass sound of the studio monitor drops longer for the extended lower frequencies.

Moreover, the configuration of the JBL 305p MK II is bi-amp, as it works with two different amplifiers, where each of them is used to adjust the low and high frequency. As two amplifiers are used to have a more profound and accurate frequency response, a more defined sound is produced by the studio monitor. And each amplifier keeps creating more dedicated frequency for the monitor than single amplifier ones.

Sound Quality of JBL 305p MK II

A versatile sound is provided by the JBL 305p MK II, so all types of sounds and songs can be accommodated by this. Most of the typical speakers can give a strong bass, but their sound lack clarity. If you test the speaker’s sound regarding its bass control, sonic balance, dynamic range, and vocal clarity, it will pass all the tests with distinction. As the studio monitor can easily handle extremely low frequencies.


And also high frequencies are easily handled. Rock music, classic music, jazz, etc everything can be played comfortably with it, as the output is bound to be really crisp and deep. And human voices of songs also sound really organic rather than muffled and processed with the JBL 305p. The sound of movies also gets really lively with this one.


The JBL 305p MK II speaker is a variant of 5 inches. The low frequency sounds hardly get scattered while playing this, rather they get controlled really well. And the high frequencies are also handled really well, so it can give you a really enhanced and magical experience while you are listening to operas or playing musicals.


And the mids are also pronounced really well and don’t get muffled by the lower ones at all. It’s clear, vibrant and natural, reflects the intention of the musician completely.

So, in a word you can get the best sonic quality for your songs or movies or whatever you play with JBL 305p MK II and with such a considerate price. You can easily buy this studio monitor from the popular marketplace Amazon with only USD 119.


They aren’t the cheapest studio monitors on the market, but they are still reasonably priced. Here, the old saying “you get what you pay for” holds true. You won’t receive some of the more costly studio monitors’ high-end features, but you won’t be left with a bunch of cheap rubbish either.

Product Differentiators

If you’re searching for low-cost hi-fi, the LSR305P MkII is hard to beat, especially since I’ve seen them for as little as £99 each.

However, if you enjoy the notion of active monitors, you might be interested in JBL’s bigger versions. The LSR308P MkII (around £500) adds an 8in the bass driver. Both variants also employ more powerful 56W amplifiers for each speaker. If you want greater volume and bass extension, look around since the LSR305P MkII’s larger siblings are available at a significant discount.

You might have a question that is scratching you from the very beginning, well let’s find out the answer.

Is it worthwhile to invest in high-priced studio monitors?

If you’re making and recording music, they’re well worth the money. It’s not totally accurate that they’ll sound bad if the environment isn’t properly treated. Studio monitors have the benefit of providing a flat sound, which implies extremely detailed sound in the lows, mids, and highs.

What is the best way to connect my JBL 305P MkII to my computer?

A 3.5mm to dual ts cable would work to connect directly to your PC. You’d have to adjust the volume from the rear of each speaker or via the glass. Get something like the jbl nano patch if you want a hardware volume knob. Two xlr cables and a standard 3.5mm stereo audio cable are required.
