I have my Sonodyne SRP 400 for a few years and can admitt that I spend more and more time with them when mixing, comparing to bigger full range monitors.

It's unbelievable how such small monitors can show the entire music spectrum in such natural way, not just the middle frequencies without reference to the rest of the frequency response

Having had the luxury of a large space in London with Dynaudio speakers, on transferring to a smaller space in a Bombay home environment I needed something that would give me power and quality but would not let the environment or space affect the sound of my mixes and my listening pleasure

I was thrilled when I had the opportunity to try out the PM 100s from Sonodyne who have been making great waves in the Indian music industry and in particular with those writing for film for many years.

This has taken me a long time to get pen to paper as I have been so busy enjoying the speakers! But from day one the sound and beauty of these speakers has been prevalent. Its always a concern how your mixes will carry from your environment to other spaces where they are played be it iTunes on a phone to a large cinema.

So it always takes effort and time and patience to ensure that what you are giving your client and/or your fans is as good in their environment as it is in yours. So that what you mix is true to what they are hearing however good or bad their system is.

So high praise for a product competing on the global stage that is home grown in India – not that its an issue, but they all ring true as the moment I switch them on in the morning to the moment I switch them off many, many hours later they have given me a great aural listening pleasure but at the same time quality that I need whether it be classical music or electronica with heavy beats.

So for an affordable pair of speakers or should I say monitors, Sonodyne’s PM 100s completely fill that space and I wholeheartedly recommend them as a wonderful near-field speaker that successfully have great control over sound whether it is quiet or loud.

For a little speaker it has an amazingly good bottom end ... even better is that you don't listen to the speaker at all, you just listen to the music

Sonodyne is proud to be associated with ASCAP as the ‘Sound Partner’ for the ASCAP Retreat in France. Held at the 14th-century Château Marouatte in the Dordogne region of France, the ASCAP songwriting retreat was designed to produce hits and get cuts in a variety of genres. Each session placed a producer, a topliner, and a recording artist together to write and record in a different room of the castle. By the end of the retreat, nearly all of the participants had worked together. They left France with hard drives full of professional-grade demos, ready to pitch to artists and record labels. This is what they have to say about their experience with the Sonodyne monitors.

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.

SONODYNE BANDISH ~ A sound engineer’s perspective

Ok so let’s have the verdict straight away… I’m really loving this offering from Sonodyne!!! It’s taken a bit of running in but now I’m really enjoying what I’m listening to.
When recording/ mixing in the studio I want to listen to audio from speakers that reproduce sound in the most accurate manner. A critical reference. I don’t want to hear coloration of the sound because of cabinet design, driver alignment etc. So, what a sound engineer requires in the studio is a neutral, unbiased response from the speakers in order to do his/ her job correctly and well.
However, when listening to music for pleasure, whether at home, on the go (headphones), at a club etc. I’m definitely not averse to a little coloration of the sound from the speakers. This should bring in the excitement to the experience. Note that I said “a little coloration”. Which means that I’m not a big fan of excessive, overpowering bass or treble or mid frequencies. The loudspeakers’ response should be relatively well balanced across the audio spectrum with a bump here and there in the response for the excitement.
Now let’s get to my experience with the Sonodyne Bandish Bluetooth speaker. I started with some of my favourite tracks (both reference as well as pleasure listening) from Steely Dan, Porcupine Tree, Dil Chahta Hai, Aquarium Rescue Unit etc. My initial experience wasn’t very encouraging because there was too much bass response. This excessive bass was distracting me from the other frequencies. Also, a low mid bump was muddying out the sound so I was losing clarity in the music. There was, in addition an unnatural sharp edge in the high frequency range.
Then I remembered that the unit is brand new and probably required some running in, so I decided that I would ignore my discomfort and let the speaker settle in with use. It would have been great if I could have been playing music at least 8 hours a day for the run in but that was not possible. I did have to leave home for work. But, every morning for a couple of hours, I would (and still do) listen to music on the Bandish ranging from Jazz to Rock to Pop. Now, over a month down the line since I got this lovely little speaker, I am very happy to report that it is settling in very nicely indeed. The initial complaints that I reported have greatly diminished and I am able to listen very happily to my favourite music in my library as well as streamed playlists.
The bass response is still a little bit on the strong side but the muddiness is gone and it’s much better defined. I’m really loving it because it’s adding to the excitement without distracting from the other frequencies. Also, the high frequency edge that bothered me very quickly went away. I guess all that really was required was a little bit of playback and the drivers settled in nicely.

The Best Review is Performance:  Longman Luk - Extremely talented Hong Kong based Erhuist shared his Sonodyne story with us recently. "I feel wonderful for having Sonodyne SRP 204 with me for some recent projects of string ensemble, acapella, and hip hop. At first I didn't expect them as such powerful for how compact the size they are. Yet the most impressive part is the aluminium enclosures, which not only make them sturdy, but also make them sound well contained and focused. As an Erhuist who works on different genres, I really like the clarity that SPR 204 brings me!"
