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

I have finally found a speaker system I can focus with, hear the depth and is tight on the hi and low end." Bil VornDick's artistry as a producer and engineer has helped earn his clients 40 Grammy nominations that encompass 7 that won (among them Alison Krauss' very first Grammy). He has worked on many albums during his 40 years in music. These include projects for such other Grammy recipients as Ralph Stanley, Marty Robbins, Bela Fleck, Jerry Douglas, Mark O'Connor and jazz bassist Charlie Haden, as well as for legendary troubadour Jesse Winchester and bluegrass empress Rhonda Vincent.

I love using my Sonodyne SM 200AKs on remote classical sessions. Since they are self-powered I don't need to haul a power amp to the session and their extended low frequency response means I get more than adequate low end content without having to rig a subwoofer and spend time on its adjustments. Best of all, the 200s sound great!

Robin Reumers, SAE Brussels Manager, talks about their Auro 3D room and why they chose Sonodyne SM100AK for this truly amazing system. We would recommend that if you get a chance to hear the Auro 3D system yourself, then grab it with both ears, you won't be disappointed. And if you can hear the system with Sonodyne SM100AK's then it will be even better.

NAKUL KAMTE

Bollywood's top sync sound engineer, National Award winner

For the last 20 years or so I used 2 sets of monitors to produce/mix on. Yamaha NS10s and Mackie HR824s (which I really only ever used towards the end of a mix to check the bottom end which the NS10s didn’t have much of). I fancied a change! I knew my NS10s inside out and while I didn’t mind the sound I didn’t love them either. I wanted something more pleasurable to work on with an extended low end yet still accurate. A couple of producers had mentioned the SM100ak monitors made by Sonodyne……..a company based in India who I’d never heard of. I also want to get some smaller monitors equivalent to the old Auratone 5Cs so I bought a pair of Avantones which are useful for checking the levels at the very end of a mix but certainly not essential because as soon as I heard the SM100AKs I was blown away!!!!!! The Avantones are an added bonus but really the SM100AKs are all I need for everything. I have never in my life heard such a natural beautiful sounding pair of monitors. Whether monitoring really quietly, really loud or somewhere in the middle the sound is warm and so accurate. My mixes translate brilliant on all systems and the Sonodynes are such a pleasure to use. My ears never get fatigued now and the lows and mids sound gorgeous with a beautiful top end. Nothing is harsh unless you make your mix sound harsh and then these mornings will really show it up as well as any other mistakes. Also the low end shows up any sounds which shouldn’t be there. More than anything the Sonodynes sound so clear. You can hear every little details and who up sounds I never before realised were there! The Sonodyne SM100ak monitors are in my opinion the best around even compared to monitors 10 times more expensive………… A no brainer in my book!
