JBL products are available in the market however, when it comes to after sales service, due to the fact that no distributor is there, it may be a challenge to get a replacement speaker in case the speaker goes bad.
Ordering online is an option however, in case you find an authorized dealer in your city, try bargaining and get a cheaper price than the price avaiable online. You will have to check with some dealers by visiting their shops and check for prices and compare with the online prices.
In case you want to come to delhi to install, I can suggest a dealer to you. Let me know if this helps
