REL, REL , REL, oh did I mention REL, and the post that started this thread is correct, you must first understand what bass really is, how it is distributed, and how to properly integrate it i to (your system).
Every system dynamics are different due to room size etc, and as mentioned before if you know where the bass is coming from you have set it up incorrectly, not only will a properly set up sub allow your main speakers sound like they are bigger then life ( not only bass but in mid range also), also learn what High level connections can do for you when it comes to a sub. I recently upgraded to a line array system for my 2 channel system (if I could post pics here I would) , and was simply blown away , granted They consist of 28 6.5" woofers and 38 3" Motorola ceramic piezo tweeters in each column , using one REL Britannia B1 sub (yes its older but works as it should), the sound is phenomenal , and breathe taking , speakers and sub are controlled through a Samson S3 crossover network, and of course bi amped .
Subs rule , but IMHO buy from a manufacturer who only builds subs for the best quality and technological attributes towards your systems dynamics.
