I can vouch for O&B, along with many other forum members. Solid product, very well built. Sounds good and Aniket is very helpful, he will answer all your queries.So our make in india products are delivering well. I had actually been eying the Sonodyne IWO on walls that have passive radiators for surround back duties as well. Had also seen the products by O&B and was considering those for LR at a later daye
Regarding Sonodyne heights and center speakers, I find them good enough for HT duties, although I have not auditioned many other speakers. If you get a chance do audition before you purchase speaker/amp.
