Cant wait to hear what you are thinking about both speakers and prefer
Okay so the Emotiva is a great sub. (In my room) it reminds me a lot of the Rythmik FV 18's I have. Very tight bass very accurate neutral but with good mid bass slam and tactile.
It has great output to 20hz but not much extension past that. You can see that in the specs +-3db from 20hz-200hz
And it shows in my REW measurements with the frequency response in room. After 24hz it's down 3db by 20hz. In room with gain when cranking I'm getting decent extension to 18hz but nothing really below that.
I believe they did that to get you that midbass that 30-60hz slam. They traded some extension for more output 25hz on up. And it has a lot of it
The finish is nice the build quality is very high. Shipping and packaging excellent. They are not small subs at all and it weighs 120lbs so be prepared.
The RSL has true extension to 16hz if your going to be using it nearfield I think
@shadyJ mentioned that you are I'd go with the RSL. Especially if this is the area you watch movies in.
Either sub is great you can't go wrong with either but your going to get better extension with the RSL and better midbass punch from 30 - 60hz with the Emotiva
