I am not trying to start an indefinite war or words here. However, is a subwoofer always necessary?
My current main speakers have 10" woofers, and pack quite a punch on their own. My old receiver did not have a Sub option. I recently upgraded, used, but still new to me, to a JVC RX 8040 130w/c(I know rated specs are never the whole truth). But my mains still kick@ss!
The new receiver has a sub out, plus pre-outs, zone 2, etc...
I listen to music/movies 50/50. However, since I have twin toddlers, not as much, or as loud as I would like.
I used a THX Demo DVD to set up the 7 surround channels, when the sub part came on, it would just quite out, however, If I turned on the "Bass Boost", I produced signal, through the 10" mains.
I am just trying to figure out if I actually need a subwoofer.
