KRK V4 S4 Review
- Balanced Audio – Compared to KRK’s Rokit range, the V4 S4 is more refined and balanced. The neutral response is better suited for more analytical studio work.
- High Quality – Excellent component quality with Kevlar woofer and excellent attention to detail. A foam pad helps with decoupling. Friction-lock Neutrik connector keeps connections secure.
- Plenty Of Tuning Options – A broad selection of tuning options to help sculpt the sound to your needs and adapt to some of the challenges that can arise from studio acoustic issues.

- Lacks Detail – While better balanced, the V4 S4 is not as clear and precise as other pro-level studio monitors.
KRK is a firm favorite, and the combination of black cabinets and yellow woofers is iconic. The V4 S4 is a step up from the entry-level focused Rokit range and offers greater depth, clarity, and a more restrained and flat response.
With impeccable production quality and a slick appearance, it is an excellent choice for home studios and new producers. But for intense production work, you might want something a bit more precise.

There is a lot to like about the Mackie CR3-X. These popular cheap studio monitor speakers offer good sound quality and volume at a super affordable price. This two-way monitor offers a 3-inch woofer and 0.75″ silk-dome tweeter, and these little speakers deliver.

It is on the pricier side, but the quality here is exceptional. The KH 80 should be on your list of options if you need a mountable monitor with excellent sound for making music.

Edifier R1850DB Review
- Flexible Connection Options – The R1850DB gives you plenty of choices in how you want to connect them. Excellent if you have a specific type of setup in mind.
- Excellent Clarity – Sound quality is impressive. Highs are clean without any harshness. The mids are crisp with no muddy tones. The low end is satisfying, but you’ll need a subwoofer if you want extra thump.
- Extended Warranty – An included 2-year warranty shows that Edifier believes in the build quality of these speakers.
- Added Remote Control – Tuning options are available at the rear but can be awkward to adjust. Luckily the included remote alleviates this problem.
- Not The Flattest Response – While excellent as all-rounders, the R1850DB speakers start to push into the hi-fi sound style. Not ideal if you plan on mixing and mastering music.
The Edifier R1850DB speakers offer impressive features at an excellent price. These are ideal if you are looking for a jack-of-all-trades set of speakers. Perfect as computer speakers or as a home audio setup for your TV.

Our Expert Buying Guide
There is a lot to consider when buying 3 or 4-inch studio monitors. Due to their size, there are some key areas that you need to pay extra attention to.
Since these studio monitors are a common alternative to computer speakers, you might want to keep an eye out for a front-facing headphone port.
This extra level of convenience can also be helpful if you want to A/B test your mixes between your monitors and your headphones.
Access to a headphone port can be convenient for A/D testing.
It is worth highlighting that most professional-grade studio monitors will not offer this feature. It tends to be more focused on consumer or prosumer gear.
But there are still plenty of quality monitors capable of light studio work that also feature a headphone port. Just because pro monitors don’t offer it doesn’t mean other options are not a good choice.
The first thing to consider is the build quality of the monitors themselves. Monitors this size are a popular target for general consumers as they are often an option as a replacement for computer speakers. As a result, many cheap and poor-quality options are in the market.
Sticking to existing and well-respected audio brands will often yield the best results. These companies have a reputation to maintain, so the quality of their products is paramount. Plus, multiple years of industry experience ensures better performance.
Master Volume Placement
This is another feature often missing from pro-level studio monitors. Usually, this is due to professional studios having a specific setup that occurs initially and is rarely tweaked later.
It is easier to adjust the volume if the control knob is on the front.
In some cases, it is also due to an external device managing volume levels rather than all the adjusting occurring on the monitor itself.
But for many home studio setups, it is not uncommon to adjust volume levels frequently. If you are in this type of setup, having a front-facing volume control knob will make your life infinitely easier.
3 and 4-inch monitors come in at a variety of different weight ratings. Things like the material used for the cabinet and internal components can have an impact.
Generally, you’ll find monitors this size relatively lightweight and nimble. This makes it easy to integrate these into your home studio without hassle. It also makes setting these on isolation pads or stands a breeze.
Sometimes, you might want to use 3 or 4-inch monitors as bookshelf speakers. If that is the case, pay extra attention to the weight rating and ensure your shelf can comfortably support them. It is also essential to keep vibrations at bay with isolation pads, so your freshly purchased speakers don’t wiggle and fall off!
Are 3-Inch Monitors Worth It?
Despite their diminutive size, 3-inch monitors are still a valid choice. As long as the sound quality is neutral and clear, you can mix and master using 3-inch studio monitors.
Which One Should You Buy?
Every monitor or set of monitors on this list has something to offer. Selecting one outright winner is difficult as every DJ, music producer, or audio professional has different needs.
From a beginner and DJ perspective, the Pioneer DM-40D does stand out for multiple reasons. It has an attractive price and looks great. The meaty sound profile is also very satisfying for daily listening and DJing, and the Production Mode is capable of light studio work. An all-rounder that can serve as a fantastic starting point.
For something flatter, the Eris 3.5 is an excellent alternative that still ticks many consumer-friendly boxes that some may be seeking. But for pro-grade quality, the Genelec is a superlative choice.
No matter which one you choose, you’ll enjoy crisp and clear sound that doesn’t overhype the lows or highs, making your time in the studio more productive and precise.
