The stereo set comprises a pair of monitors, one active and the other passive. The cabinet material is MDF and the front baffle has a unique moulded shape. The 1 inch silk dome neo-magnet tweeter is nested in an elliptical custom waveguide for a smooth response and wide directivity in horizontal plane but controlled directivity in vertical plane.

Sonodyne is a heritage. Even my dad was a big fan of Sonodyne. However, this was my first Sonodyne product. Initially, I was not sure whether I should go with the purchase, as I was not able to test it in person from Pune. Still went ahead with the nostalgia. It's an excellent pair in this price range and even in ranges above. Sound signature is well balanced, well tuned drivers, it's comfortable and the ANC istop-notch. Nice build quality. Two hiccups for me. One was the exclusion of any carrying case or bag with the product. Even a simple carrying pouch would have been really appreciated. Secondly, the branding could have been better positioned and more subtle. Would have given it a more cleaner asthetics.

From my very childhood, I heard about Sonodyne. Finally after so many years, I have got a chance to bless myself with Sonodyne speakers (not actually, as they are active production monitors). I bought them not for recording or mixing purposes, just for home listening. After tremendous amount of research on internet and a thorough market study regarding sound quality (have come across the sound of KRK Rokit 8 and Adam A7x, Monkey Banana, JBL lsr 308 etc with live demonstration), I came to the conclusion with PM 100s. Many people may question, if it is for home listening, then why didn't you go for hifi speakers?. My answer to your question is that I have owned two renowned (not mentioning the names) hifi systems earlier. But they can never give you such detailed sound with dynamics. There would always be coloration (either at the highs or at the lows) to the tunes you play. Now coming to the PM's part, I seriously don't have words to express my feelings about Sonodyne. I love detailed sound with each and every note, being distinctly audible. Sonodyne exactly serves that with tremendous amount of power. Highly recommended for serious audiophiles, not for those who crave only for heavy bass response and not clarity.
