You can't really drop in any woofer into your cabinet. Specs matter. I don't see many affordable 8 inch woofers in India. Probably Bolton ( extinct ?), or Iwai or Dainty ( car speakers). Other brand woofers ( or sub-woofers ?) are available on Amazon.in .
What's wrong with your current Philips woofer ? Maybe you can fix it ?
Look at the offerings at diyaudiocart.com and diyaudioparts.com.
Always try to measure the T/S parameters of your driver. Usually expensive drivers are close to published specs but less expensive drivers can be all over the place.
Why is it mentioned full range speakerThanks for the suggestion, I will have to digest this in detail for my future projects...
1. what equipment do I need to measure T/S?
what basic setup I would need? (lower cost will be good).
2. what kind of SPL meter do I need to get the the speaker frequency/SPL graph produced?, some sort of mic-software combo?
Any ways, the drivers arrived and they fitted perfectly in the existing cutout.
Fired the speakers with my fingers crossed... happy ending with satisfying result... thanks @hydrovac for a good pointer.
