That's very kind of you. I'm very glad you liked my rig. You'll like it even better when you demo it next time. For now, I'm looking for an omnidirectional mic to work on the EQ. Can't seem to find any here in Lahore. I'm expecting better results after EQ. And thanks again for the praise. 
Wsalam sir. If you are in Lahore, you might want to consult Shehzad @soundworks, Liberty. He'll source the DSP for you. And you can also PM me whatever you wanna know about it. I'll be glad to help. Helix A4 would be a great option for the mids and tweets - Xenon 200.2 is also a splendid choice. I'm sure you won't feel the urge to replace it later, since I just recently installed a similar one, and had great results. As far as the sub goes, it depends on your budget. There is a new JBL sub available, which is the replacement for the beloved p1224. It is called s3-1224. JBL S3-1224 1500w 12" Series III Subwoofer with Selectable 2-Ohm or 4-Ohm Impedance . I haven't listened to it yet, but it seems promising. I read very positive reviews about it too. If you wanna spend more than this, I can assure you the Gti series from JBL is absolutely insane - It'll be hard to find a Gti series sub though. Moreover, there is a Focal Utopia sub for sale on PW as well - Mithu is the seller. About the kappa, there is one for sale here on PW, also there is a used one available at Soundworks too.
Thanks for your humble words, Yawar. I must say, I was surprised myself how good these speakers paired up with the new rig. Going full-active also brought about the control needed to unleash their maximum potential. Moreover, I plan on eventually trying the upgrade we discussed to the speakers department - I'm curious to see the response then.
I'm surely gonna demo your setup as well when I visit Karachi.
