Thanks everyone for your feedback.
I am not a purist / audiophile, but I love listening to music with good sound clarity / details. Earlier, I owned a Sony DHC-AZ5D 5.1 system but I was not very happy with the performance. So I wanted to build-up my customized home theater system with an extremely limited budget.
My budget for immediate spending was around Rs. 50K, so I booked Yamaha HTR-3072 + Yamaha NS-8390 (FS Speakers). Received the package within 4 days of booking (excellent service by avbestbuy.in: highly recommended).
Setting up the system was absolutely hassle free. I have also hooked-up the surround speakers of my old Sony home theater. So far so good….. I have build-up a 4.0 system! Then I connected one of the front speakers of the old system as the center speaker to make it 5.0!! But I could not make it 5.1 as the old subwoofer is a passive one.
So my immediate requirement is a subwoofer. By the time you guys must have figured out that I am not going to look beyond Yamaha NS SW-050 or NS SW-100. Both are 50W subs with only difference being the driver: 8” vs. 10”. Since output power is same, is it worth to pay the extra buck just for the driver size? Please advise. Any other sub in the same category / price range?
