Speaker cable pre-wiring: CL2 or non-CL2

[devang]

I am in the process of finalizing my HT setup, but since house interior work is being done, I want to have the cabling done right.

Room size 11x18 ft (HT area would be 11x11)

I am going to have speaker wires concealed in the wall. I read it that for such in-wall installation, CL2 cables have to be used. Is it absolutely necessary to have these cables? There is a segment on the speaker wire path that is too shallow and I cannot have very thick wires. If I must have CL2 wire, I would have to find some solution.

(a)Coboc Model SPW-CL2-2C14-100-WH 100ft 14AWG CL2 Rated 2-Conductor Enhanced Loud Oxygen-Free Copper OFC Speaker Wire Cable (For In-Wall Installation) - Newegg.com --> Is this a good choice?

or can I live with
(b) DAC SPK14 AWG OFC Dual Speaker Cable

sir dac 12awg will do for the rears 12awg or 10 awg for fronts and center i think this will do .......don't pass speaker wire along with electrical cables ,, use separate tubes for speaker wiring
