If you own a pair of Monitor Audio speakers, you already have a solid foundation for great sound. But even excellent speakers can sound mediocre in a poorly treated room, with mismatched amplification, or through low-quality cables. The good news is that a series of targeted upgrades—some costing very little—can dramatically improve clarity, bass tightness, and imaging.
This guide walks you through every step of the process, from choosing the right components to fine-tuning with room correction. Whether you are a first-time upgrader or a seasoned enthusiast, you’ll find actionable advice that respects your budget and your time.

Choosing the Right Components
A coherent system outperforms a collection of expensive parts. Start by evaluating your current Monitor Audio model—the entry-level Bronze series, the mid-range Silver, or the flagship Gold—and decide what aspect of the sound you want to improve.
Selecting Upgraded Drivers
The driver (woofer, midrange, tweeter) is the heart of the speaker. Monitor Audio uses proprietary technology such as C-CAM (Ceramic-Coated Aluminium/Magnesium) cones. If you are repairing or modifying an older pair, replacing a damaged driver with an original OEM part preserves the intended voicing.
- Size matters. A larger woofer (e.g., 8-inch vs. 6.5-inch) moves more air for deeper bass, but it requires a larger cabinet and more amplifier power.
- Material changes the tone. Silk dome tweeters sound warmer; metal dome tweeters (like Monitor Audio’s gold dome) offer more detail and sparkle. Stick with the original material unless you are confident in crossover redesign.
- Fitment check. Measure the cutout diameter and depth. Aftermarket drivers may need adapter rings.
Enhancing Crossovers
Crossovers split the audio signal into frequency bands for each driver. Upgrading capacitors and inductors can reduce distortion and improve phase alignment.
- Use polypropylene film capacitors (e.g., Dayton Audio or Mundorf) instead of cheaper electrolytic ones. They handle high frequencies more cleanly.
- Replace iron-core inductors with air-core inductors for lower insertion loss.
- Check the physical size: a high-quality air-core inductor can be bulky. Confirm space inside the cabinet before buying.
A common mistake is overspending on boutique components. A well-designed crossover with standard parts often sounds better than a poorly matched exotic one.
Improving Cabinet Design
Monitor Audio cabinets are already well-braced, but older models may benefit from additional damping.
- Add bitumen pads or NoRez sheets to the interior walls. This reduces panel resonance.
- Fill the cabinet cavity with long-fibre wool or acoustic polyester stuffing (not too tightly) to absorb internal reflections.
- Check the seal around the driver and terminal cup. Leaks cause “chuffing” and loss of bass definition.
If you are building a custom enclosure, use 18 mm or thicker MDF with internal cross-bracing. A rigid cabinet lets the driver do its job without colouration.
Optimizing Speaker Placement
Even the best Monitor Audio speakers sound congested if placed poorly. The room is the biggest variable in your system.
Ideal Room Positioning
- Keep speakers at least 30 cm (12 inches) from the rear wall, and 60 cm (24 inches) from side walls. This reduces boundary bounce that smears bass and midrange.
- Form an equilateral triangle between the two speakers and your listening position. Each side should be between 1.5 m and 3 m (5–10 ft).
- Avoid corners. A corner loads the bass by about +6 dB, making it boomy and slow.
Adjusting Height and Angle
The tweeter should be at ear height when you are seated (typically 90–110 cm / 36–43 inches). If your desk or stands are too low, use a sturdy riser. A height-adjustable desktop monitor stand can also serve as a speaker riser when paired with isolation pads—keeping your workspace neat and your sound on-axis.
- Toe-in the speakers so the tweeters point directly at your ears. Start with 5–10 degrees of toe-in and adjust until the centre image snaps into focus.
Using Isolation Pads
Decoupling speakers from furniture stops low-frequency vibrations from muddying the sound and rattling your desk.
- Place sorbothane pads or foam isolation feet under each speaker.
- For bookshelf speakers on a shelf, use a layer of Blu-Tack between the speaker and the surface.
Upgrading Amplification
A Monitor Audio speaker will only sound as good as the amplifier driving it. Match power and impedance carefully.
- Wattage. Aim for an amplifier that delivers at least 1.5× the speaker’s continuous power rating. For a 100 W speaker, a 150 W amp gives clean headroom for dynamic peaks.
- Impedance. Monitor Audio speakers typically run at 8 ohms nominal but can dip to 4 ohms at low frequencies. Choose an amplifier that is stable into 4 ohms (check the spec sheet).
- Type. Solid-state amps (e.g., Cambridge Audio, Rotel) deliver precise, neutral sound. Tube amps (e.g., PrimaLuna) add harmonic warmth. The right choice depends on your taste; for critical listening, a neutral solid-state amp lets the Monitor Audio character shine.
A common upgrade path is to move from a receiver’s internal amp to a dedicated stereo power amplifier. The improvement in clarity and control is immediately audible.
Improving Wiring and Connections
Cables are the least expensive upgrade that can make a real difference—provided you choose sensibly.
- Speaker wire. Use 14 AWG or 12 AWG oxygen-free copper (OFC) for runs up to 7.5 m (25 ft). Thicker wire (12 AWG) for longer distances reduces resistance.
- Interconnects. Shielded RCA cables (e.g., Mogami, Blue Jeans Cable) prevent hum and radio frequency interference.
- Banana plugs. They create a solid, repeatable connection and prevent loose strands from shorting.
| Technique | How It Works | Benefit |
|---|---|---|
| Bi-wiring | Two separate cables from the same amp to bass and treble terminals | Reduces intermodulation distortion; subtle in practice |
| Bi-amping | Dedicated amps for low and high frequencies | More power and headroom; noticeably cleaner bass |
Note: Bi-wiring only matters if the speaker’s crossover is designed for it. Most Monitor Audio models have removable jumper plates – removing them and using two cables can reveal a small improvement. Bi-amping requires an active crossover or a pre-amp with dual outputs.
Keep cables away from power cords and Wi-Fi routers. Use flexible cable management arms to route speaker wires cleanly under your desk or along baseboards. Tidy cabling also prevents accidental tugs that can damage connectors.
Tuning and Calibration
Room correction software fixes issues that no hardware upgrade can.
- Many modern A/V receivers include Audyssey or Dirac Live – run the full calibration with the supplied microphone. This measures reflections and adjusts EQ and timing.
- For stereo systems, use Room EQ Wizard (REW) (free) with a calibrated USB microphone (e.g., UMIK-1). Generate a target curve and apply it via a miniDSP unit.
- Start with a flat frequency response (no EQ), then add a gentle 1–2 dB boost below 80 Hz if you want more bass impact. Cut room nodes (peaks) rather than boosting dips – boosting risks distortion.
A well-calibrated system sounds natural across all listening positions, not just the sweet spot.
Adding Acoustic Treatments
Before buying expensive gear, treat the room. Even a few panels dramatically improve clarity.
Reducing Reflections
First reflections – sound that bounces off the nearest wall, ceiling, or floor before reaching your ears – cause comb filtering and smearing.
- Place 2-inch thick acoustic foam or mineral-wool panels at the mirror points: sit in your listening chair and have a helper hold a mirror flat against the side wall; slide it until you see the speaker. Mount a panel there.
- Use a thick rug on a hard floor between you and the speakers.
Managing Bass Response
Bass nodes (standing waves) cause one-note boominess. The cure is bass traps in the corners.
- Install corner bass traps (foam or membrane) in as many corners as possible. Two traps in the front corners give the biggest reduction.
- A 50–100 mm (2–4 inch) gap between the trap and the wall improves absorption at lower frequencies.
Incorporating Diffusers
Diffusers scatter sound evenly, preserving liveliness without echoes.
- Place a skyline diffuser or binary-array diffuser on the rear wall behind your listening position.
- Wooden diffusers work well; they add a small amount of broadband absorption too.
Integrating a Subwoofer
A dedicated subwoofer offloads deep bass from your main speakers, reducing distortion and giving you cleaner midrange. Monitor Audio’s own subwoofers (like the Gold W15 or Silver W12) are naturally voiced to match, but any quality sub can work.
- Set the crossover point to 80 Hz (THX standard). Most Monitor Audio floorstanders can play down to 30–40 Hz, but crossing at 80 Hz takes strain off the amp.
- Use a Y-adapter if your pre-amp has only one subwoofer output, or run dual subs for smoother bass across the room.
- Place the subwoofer near a corner or along a wall, then move it while playing a 50 Hz tone until the output is loudest and cleanest. Alternatively, use the “subwoofer crawl” method.
Upgrading the Digital Source
If you stream music from a computer or phone, the digital-to-analogue converter (DAC) is a weak link.
- An external DAC (e.g., Topping E50, Schiit Modius) bypasses your computer’s noisy audio chip. Look for a DAC that supports 24-bit/192 kHz or higher and has a USB input.
- For streaming, a dedicated network streamer (e.g., Bluesound Node, Wiim Pro) gives you high-resolution playback (up to 192 kHz/24-bit) and often includes room correction.
A good DAC and streamer can reveal detail you never knew your Monitor Audio speakers could produce.
Maintaining Your Monitor Audio System
Regular care keeps components performing like new.
- Dust drivers every month with a soft, dry microfiber cloth. For metal tweeters, use a clean makeup brush – never a vacuum.
- Inspect cables for frayed ends or bent pins. Replace any that show wear.
- Check firmware once a year. Monitor Audio’s active speakers and subwoofers (e.g., the Platinum II series) receive updates via the manufacturer’s app or website. Firmware can fix DSP bugs and add new features.
If you store speakers long-term, keep them in a dry, temperature-stable room. Extreme humidity can corrode voice coils.
The signature gold dome tweeter is a hallmark of Monitor Audio’s design philosophy.
Frequently Asked Questions
Can I upgrade Monitor Audio speakers without replacing the whole cabinet?
Yes. The most impactful upgrades are crossover components, internal damping, and isolation feet. Driver swaps are possible but require careful matching.
Do I need a subwoofer if I already have floorstanding speakers?
Not necessarily. Floorstanders like the Silver 300 already produce solid bass down to 30 Hz. A sub helps if you want deeper extension (below 25 Hz) for movies or electronic music.
Should I always bi-wire my Monitor Audio speakers?
Bi-wiring offers a small improvement in clarity if your amplifier has two sets of binding posts. It is not mandatory. Bi-amping gives a bigger benefit but requires more hardware.
How often should I update firmware on active Monitor Audio models?
Check every 6–12 months. Updates are free and can improve DSP-based crossovers and connectivity.
What is the most common mistake people make when upgrading speaker audio?
Ignoring the room. Even a modest system sounds fantastic with basic acoustic treatment, while an expensive system in a bare concrete room will sound harsh and boomy.
A clean workspace with proper speaker placement and cable organisation reduces interference.
Conclusion
Upgrading your Monitor Audio system is a journey, not a single purchase. Start with the fundamentals: speaker placement, isolation, and room treatment. Then refine your amplification, wiring, and digital source. Each step builds on the last, and the cumulative effect is a soundstage that is wider, deeper, and more lifelike.
