Dual mono with REL Subwoofer

He also said G1 and No 25 is designed to be stack of 3 each side.

He told me subs that sits low will never sound good, the height factor of 212/SE contributes a lot. Which means if you go for G1 or No 25, it is designed to be stacked, you need to get at least 2 or 3 each side.

The G1 MK2 used class AB amp, 212SE used a Class D 1000Watt amp like the No 25 has, I heard other users compared G1 and 212SE and they found 212SE is much faster than the G1 MK2 due to the Class D amp.

I haven't heard the G1 or No25, but I heard the S5 Carbon, S5 SHO and 212SE. the S5 Carbon used same driver as G1, it does sounds better than S5 SHO, more output, but its no where as good as the 212/SE, can I say that carbon driver doesn't help that much as we expected?

Stacking is for large rooms. My 18 x 18 Ft room cannot handle that. And neither can my pocket .. 

I do not agree that Subs that sit low will never sound good. And also that a sub with Class A/AB amp does not sound good vs. a sub with a Class D amp. 

You need to hear the G1 MK-II or the No.25 first. 

However, I am all 'guns for a Pair of G1 MK-II' and will be implementing this soon. And regarding the method of connecting the RELs, I will use High-Level with the Black wire affixed to the GROUND Terminal under the Phono RCAs on the Devialet. 

Once again, please try and hear the G1 or the #25 paired with high-end loudspeakers at a dealer ... you may change your opinion on them.
