Bro, the Orbs only have 1 model lar...that's the Mod1 (single unit), 1 unit become Mod2 and so on 
You would be surprise how loud it can play for it's small size and using as a surround is very good, only complaint is that it cant go too low so my LFE xover have to cut off at 100-120Hz (recommended is 120Hz but I set mine at 100Hz)

I got similar issue... Now I do not have a wall at the back to bounce back rear. Me clever+clever go and re-arrange the living room and now sound quality got compromised. The HM says the living-room arrangement stay-put and I need to think of a solution that have WAF.
I am thinking of something that can be moved around therefore in-wall is out. This is in-case, me got the clever+clever thingy and re-arrange again.. Therefore looking at wall-mounted, placeable satellite that can be moved easily to another location without much ado.. Also prefer satellite that can play below 100Hz. Now wiring is acceptable a bit as some wire no issue.. only speaker must look nice and sleek.. as HM demand it. No boxey shape as so "old-fashion" she say...         

KEF is now being distributed by Perfect Hi-Fi.

It would be slightly above your budget.

can you tell me how much this will be, a breakdown of prices according to items would be nice. thanks sifu!

Quintet : RM1,470
RPW-10 : RM1,450

AVR-1910 : RM2,500

how's the sound effect it'll be? nice enough to immerse audience? good enough for home use, for those who really enjoy watching movies although the movie is years old? but if change the sub to a SVS, how, still can match ah sifu?

It is entry level system which is good enough for normal movie watching.

If to get SVS sub, even the entry level, I am afraid that it will overpowers the speakers with ease . To have SVS in there, you have to get a better entry level speaker system.

Depending on how loud that you crank the volume and how hot that you run the sub.

Not necessary to go for a full SVS setup. You still can go for other brands to partner with it. In US, Klipsch, PSB, B&W, Axiom, etc are being partnered with SVS.

You only need to match its series. If 12-Plus, then you need to have midrange loudspeakers system such as PSB Imagine, Klipsch Ref IV series and so forth.

Yes, bipole or dipole would be ideal for 5.1 system as it is able to disperse sound wider than conventional direct radiating speaker.

Bro,  a satelite will never ever outperform a floorstander due to physics   . The MS will outshine it by a considerable margin with ease due to its dual 6.5" woofer as well as its volume.
