Eh hem!...Subwoofers... What do ya know?

gochurchgo, here are some starting point guidlines for a speaker placement and a youtube for the Crawl Test subwoofer placement. Since not every room has four corners, mapping out your rooms bass modes (where bass is louder) can be very usefull.

Not every speaker system was designed to be toed in.

Subwoofers are a poor attempt in 2 channel listening.  If your speakers do not put out a decent bass response then it is what it is.  Subwoofer integration should be left for Home Theatre enthusiasts looking for bombs going off in their listening spaces.  I have tried sub integration and as a Bass player it does no justice.  Buy a speaker that produces a proper bass responce there are enough out there.

Further.......it puzzles me why individuals buy speakers with poor bass response...

I am quite fond of my ENTEC SW-1. 

Bah ! Subwoofers ! You kids and your rock and roll music . 
My mains have all the bass response I’m sure some would like to have . But i also want six subs . And since i do what i want ..
seriously though i think people do not use them properly to get a hifi effect out of them . I guarantee the majority could turn them down a notch to achieve proper reinforcement. Turn it down to the point where you actually have to feel the woofer to see its on . Then leave it there chances are if its in the right location as explained ten times on here it will sound perfect .
