He has listings on Amazon with the S-Grid Audio. However, the place I went to was just a demo room and did not have a board with name. It's also not marked on Google maps. He has a store/warehouse in Bhiwandi. I'll get his card next time I meet him.
Auditioned DNM audio speakers with Mr. Dilip Bajaj of DNM Audio near Saki Naka, walking distance from the metro station.
The set I auditioned was satellite speakers, I guess the ones listed as Tango 1 on their website
http://dnmaudio.com. These are tiny looking speakers, not a great design, but also won't look out of place in a middle class household. They come with wall mounts and cost just Rs. 1800 a piece as of now. They were paired with an active subwoofer which is two 5.25" units.
I don't have much experience with speakers yet, so I won't try to go into too much detail and will just tell my general impression. The speakers were quite powerful for their size and produced a room filling sound. I was not vastly impressed with the sound quality, but I would say they are really good for the price. The sound was loud and clear. I noticed some distortion in the highs at loud volume when a clip from Fast and Furious was playing. The highs weren't very impressive, but dialogue clarity was pretty good.
Initially he connected a 12" subwoofer. This produced very satisfying rumbles. However, I neither have the budget nor the inclination for a such a large subwoofer. So he then connected the cheapest subwoofer, which he said would cost somewhere around 13k, but are currently out of stock and I might have to wait for a month or so. This smaller subwoofer also felt powerful enough for a small room. However, the quality of the rumbles definitely deteriorated. I don't know the technical terms for these, but I would describe it thus - with the 12" sub, I could feel the bass more than I could hear it, but with the smaller sub, I could hear it more than feel it. I was far more aware of the bass being there, which was slightly unpleasant and distracting. I guess I can take care of that to an extent by reducing the volume of the sub.
Coming to the things I didn't like much, Mr. Bajaj seemed to be in a hurry throughout the demo. He didn't talk or explain anything to me, just sat there by the side as I watched one clip after another. They also didn't have a player for my own media, so I couldn't take clips which I had used in my previous demo, which restricts my ability to do a 1 to 1 comparison of different speakers I'm listening to. I guess part of it was because of my low budget. The whole thing would cost just 22k, which might not be enough for them to spend much time on. They also don't give any warranty on speakers and only 6 months on the subwoofer amplifier.
Overall, if someone is looking at getting a home theatre on a tight budget, I'd definitely recommend looking at these speakers. I doubt you're going to find anything this good for 9000 Rupees. I personally haven't seen anything other than the Micca Covo S for this price listed online.
