How to choose your studio monitors? The complete guide

Studio monitors are the reference point of your studio. If they lie, your mixes lie everywhere else. A bad pair of monitors makes you compensate for nonexistent lows, mask exaggerated mids, and deliver a mix that sounds good on your system but nowhere else. This guide helps you choose the right monitors based on your room, your budget, and your use case.

Quick summary

• Active: built-in amplifier, direct connection. The home studio standard. Example: Focal Alpha 50.
• Size: 5 inches for small rooms (< 15 m²), 6-8 inches beyond that. Example: Genelec 8040B.
• Beginner budget: Mackie CR2-x or PreSonus Eris 3.5 — perfect to get started.
• Pro studio budget: Focal Alpha 50 or Genelec 8040B — quality without compromise.
• Understood: headphones don't replace monitors. Also check out our audio interface guide.

Monitoring or Hi-Fi: what's the difference?

Hi-Fi speakers embellish the sound. Studio monitors reproduce it as is, without embellishment. It's this neutrality that allows you to make good mixing decisions: if you hear a problem on studio monitors, it's because there is one, not because the monitors are creating it.

A Hi-Fi speaker can make you believe your mix sounds good when it's actually unbalanced. A studio monitor tells you the truth, even when it's hard to hear. That's why you don't mix on Hi-Fi speakers.

Active or passive: which to choose?

Active monitors: the amplifier is built into the speaker. Plug in the signal from your audio interface, that's it. Advantages: simplicity, amplification optimized for each driver, no need to buy a separate amp. It's the standard for the modern home studio — 95% of studio monitors sold today are active.

Passive monitors: the amplifier is external. You choose the amp, the cables, the configuration. Advantages: modularity, ability to upgrade the amp without changing the speakers. Disadvantages: more complex, more expensive overall, requires knowledge of amp-speaker matching.

For 99% of home studios, go with active monitors. The Focal Alpha 50 are an excellent example of active monitors that offer a remarkable value for money.

What size monitors to choose?

The size of the woofer (the low-frequency driver) determines the response in the low end of the spectrum. The larger the woofer, the lower the speaker goes in frequency. But a large speaker in a small room creates resonance problems.

Golden rule: a small speaker well placed is better than a large speaker that resonates. If your room is less than 15 m², stick with 5 inches.

Our selection of studio monitors

PreSonus Eris 3.5 BT — The entry ticket. 3.5 inches, built-in Bluetooth, perfect for a desk. The sound is honest for the price — not precise enough for pro mixing, but more than enough to learn, listen to references, and do pre-mixing. Bluetooth is a bonus for listening to music wirelessly.

Mackie CR2-x — The budget alternative. Mackie is a reference in affordable monitoring. The CR2-x offer balanced sound for less than €150 a pair. Ideal for a first home studio, a podcast, or streaming. Don't expect deep bass, but the mid-high range is clear and precise.

Focal Alpha 50 — The mid-range reference. 5 inches, bi-amplified, made in France. Focal designed the Alpha line to deliver professional sound at an accessible price. The frequency response is flat and honest, the bass is present without being exaggerated, the midrange is remarkably clear. This is the speaker I recommend to any musician who wants to get serious without breaking the bank.

Genelec 8040B — The professional standard. 6.5 inches, bi-amplified, legendary Finnish design. Genelecs are the reference speakers in professional studios worldwide. Their neutrality is exemplary, their stereo imaging exceptional, their reliability legendary. As refurbished used units at Green Musicians, it's an investment that lasts 20 years.

Alto M3A — The versatile option. Active speakers that can serve for monitoring AND small PA. If you need speakers that do double duty (studio + small stage), it's an interesting option on a tight budget.

Positioning: where to place your monitors?

Even the best monitors will sound bad if poorly placed. Here are the essential rules:

• Equilateral triangle: the two monitors and your head form an equilateral triangle. Speaker-to-speaker distance = speaker-to-head distance.
• Height: tweeters at ear level. If the monitors are too low, get stands.
• Distance from wall: at least 30 cm from the rear wall to avoid bass cancellation. The closer to the wall, the more the bass is amplified (sometimes falsely).
• Symmetry: both monitors must be at equal distance from the side walls. Asymmetry creates stereo imbalance.
• Isolation: use acoustic foam or pads under the monitors to prevent vibrations in the desk.

FAQ: your questions about studio monitors

Should you treat your room to use studio monitors?

Not necessarily to get started, but highly recommended for mixing. Monitors interact with the room — reflections, resonances, room modes. A few absorptive panels at first reflection points transform the sound.

Is a subwoofer necessary?

Not to start. A sub becomes useful if you mix electronic, hip-hop, or film, where sub-bass (20-40 Hz) is important. For most music, 5-inch monitors are enough. Also read our XLR or USB comparison for connectivity.

Can you mix on headphones only?

Technically yes, but it's discouraged. Headphones don't reproduce stereo imaging the same way monitors do. Use headphones to check details, but mix on monitors. For headphones, check out our studio gear guide.

How much to spend on your first monitors?

Expect €150-300 for a good entry-level pair (Mackie CR2-x, PreSonus Eris), €400-600 for mid-range (Focal Alpha 50), and €1000+ for pro (Genelec). Refurbished used gear at Green Musicians lets you step up a tier in each budget.

Summary of key points

• Monitoring = neutral, Hi-Fi = embellishes
• Active = built-in amp (95% of the market)
• 5 inches for rooms < 15 m²
• Beginner budget: Mackie CR2-x or PreSonus Eris (~€150)
• Quality budget: Focal Alpha 50 (~€500)
• Pro budget: Genelec 8040B (~€1500)
• Equilateral triangle + tweeters at ear level
• Acoustic treatment matters as much as the monitors

Conclusion

Studio monitors are the most important investment in your studio — more than the microphone, more than the interface. A bad mic on good monitors will always sound better than a good mic on bad monitors, because you'll hear what's wrong. Start with a pair of Mackie CR2-x or PreSonus Eris at €150 to learn, then move up to Focal Alpha 50 when mixing gets serious. And if you have the budget, used Genelecs will accompany you for 20 years. Don't forget: placement and room treatment matter as much as the monitor itself.
