Sonodyne SRP 204 is 1.4Lakhs primarily due to the Aluminum die cast body.
There is a PM100 from Sonodyne that feels like a good alternative with similar drivers and frequency response range and a class AB inbuilt amp. However the lack of aluminum die cast body primarily brings the cost down.
I believe Sonodyne SRP204 will cost around 1.2 Lakhs for pair

You can consider lower models like SRP 202 or SRP 203 as well
SRP 204 each speaker takes separate inputs, so you can add more speakers if you are able to give more inputs.
Mostly these are used for stereo music listening. It will be costly to setup home theater setup using such active speakers, better option will be use AVR and passive speakers.
