3-Way Tri-Amplified Design

Dedicated amplifiers for the woofer, midrange and tweeter ensure every frequency is driven with optimum power and precision. The result is superior clarity, lower distortion and exceptional detail across the entire audio spectrum.

Aluminium–MDF Hybrid Rigid Enclosure

Aluminium–MDF Hybrid Rigid Enclosure

A unique hybrid cabinet combines the rigidity of extruded aluminium with the acoustic damping of MDF to minimise unwanted resonance. This creates a cleaner, more accurate sound with improved imaging and tighter low-frequency performance

Kevlar Woofer & Midrange

Kevlar Woofer & Midrange

Premium Kevlar drivers deliver an ideal balance of stiffness and low mass, providing fast transient response with minimal cone breakup. The result is articulate bass, natural mids and exceptional detail, even at high listening levels.

Custom High-Frequency Waveguide

Custom High-Frequency Waveguide

The precision-engineered waveguide optimises high-frequency dispersion, delivering a wider sweet spot, stable stereo imaging and consistent tonal balance both on and off axis.

3-Band Acoustic EQ

3-Band Acoustic EQ

Built-in acoustic EQ controls allow the monitor to be fine-tuned for different studio environments and speaker placements. This helps maintain a neutral and accurate reference regardless of room acoustics

High Detail & Dynamic Performance

High Detail & Dynamic Performance

From subtle vocal nuances to explosive transients, the SM 300 reproduces every element with remarkable accuracy and headroom. Its wide dynamic range makes it an ideal reference for recording, mixing and mastering applications.

What is the Sonodyne SM 300 designed for?

The SM 300 is a professional 3-way active studio monitor built for recording, mixing, mastering and post-production. Its highly accurate sound reproduction makes it an ideal reference for critical listening.

What are the advantages of a 3-way tri-amplified design?

The SM 300 uses dedicated amplifiers for the woofer, midrange and tweeter, allowing each driver to operate independently. This delivers greater clarity, lower distortion and improved accuracy across the entire frequency range.

Is the SM 300 suitable for professional studios?

Yes. With its high output capability, wide frequency response, exceptional detail and low distortion, the SM 300 is equally at home in professional recording studios, broadcast facilities and post-production suites.

Can I use the SM 300 in a home studio?

Absolutely. The SM 300 is ideal for serious home studios where accurate monitoring is essential for producing mixes that translate consistently across different playback systems.

Why does the SM 300 use Kevlar drivers?

Kevlar offers excellent stiffness with low mass, enabling faster transient response and reduced cone breakup. This results in tighter bass, natural midrange reproduction and outstanding detail.

How does the custom waveguide improve performance?

The precision-engineered waveguide provides consistent high-frequency dispersion and a wider listening sweet spot, helping maintain accurate stereo imaging both on and off axis.

Can the SM 300 be tuned to suit different rooms?

Yes. The monitor features bass roll-off and high/low shelving EQ controls, allowing you to optimise its response for your room acoustics and speaker placement.

Is the SM 300 manufactured in India?

Yes. The SM 300 is designed and manufactured by Sonodyne in India, backed by more than five decades of expertise in professional audio engineering.

Reviews

For audiophiles, Sonodyne has been a legendary Make in India brand, & the Bandish offers 120W of pure grade sound!

★ ★ ★ ★ ★5/5

Akash Banerjee (DeshBhakt)

Sonodyne is an Indian brand many of us (and some of our parents) grew up with, and my earliest memories of the brand date back to the late '80s/ early '90s, when I used to regularly visit an uncle in Kolkata who was a big fan of the brand and its single-minded focus on recreating music "as the artist intended". Fast forward to 2024, and while the brand continues to serve the serious audiophile and pro-studio markets, it's their Bluetooth wireless speaker range that caught my eye, specifically the most powerful in their range, the aptly named Malhar (after the raga , Malhar which, as the myth goes, has the power to induce thunder and rain). Not one for slimline aesthetics, the Malhar resembles a cajón (or a clapbox as many may know it), an immediate throwback to when audio equipment was engineered for producing clean sound, first and foremost. With its wooden cabinet, classic aesthetics and all, the 8-kilogram Malhar is pleasing on the eye, but it demands pride of place — it's not one to disappear into the décor. Around the front are two 5" glass-fiber cone drivers accompanied by two 1" tweeters, and the sides have two 5" passive radiators. Inputs are all clustered towards the rear, with optical, aux, USB ports along with a handy 5V DC USB port to charge a phone while it's connected to the speaker. Controls to switch between these inputs and change tracks/volume are all on the top and are mirrored on the supplied remote. No buttons to fiddle around with bass/treble settings (intentionally so to retain the original feel of the track), and I would have preferred the indicator LEDs to be more visible, so you know the speaker is on or which input is selected. No app or Wi-Fi connectivity, which one starts expecting at this price point. Any reservations you may have had subside the moment you start playing music on the Malhar. Irrespective of genre, the speaker stands up and delivers, with a balanced sonic signature that accurately renders the highs, mids and lows without colouring the audio, so to speak. Streaming tracks as varied as Simon and Garfunkel to the Beach Boys to some of AR Rahman's classics, Malhar reproduces the tracks damn near flawlessly across its wide 40Hz – 20kHz frequency range. Throw in some punchier tracks and bump up the volume, and you really have to wake up the neighbours before the speaker starts showing the slightest hint of distortion at the top end. Worth noting as well is the expansive soundstage and the open quality to the playback. At its price, Malhar is likely to appeal to audio purists, and despite its name, this truly is a speaker for all seasons. The 'Made in India since 1970' is bonus appeal. Rating: 8/10 Price: INR 37,500
