What size subwoofer to get?

I had this dilemma once and decided it was far more cost effective, and would also yield overall better sound, to sell my speakers for a fullgrown full range model. With the seperate sub imaging will be lost. As I understand it you should crossover one octave above your speakers bottom extreme for best results, so around 70Hz, which can be done with the Outlaw Audio bass managment system (www.outlawaudio.com). Also worth note, of the thousands of songs I have on disc of all types of mucis, maybe a dozen have anything portrayed below 35hz, of those I have only 2 tracks with any info from 25hz on down, and it is electronica/techno/trip-hop type of music, so unless you listen to such musik, or I suppose organ music, you're not missing much....

How do you know that I have no first hand experience? An unusual assumption, no? I have heard numerous setups with seperate subs, I find them inferior in many ways to similar quality and priced full range speakers, though sub setups often end up more epxensive in the end once you factor in cables and a good crossover, which is why it makes little sense to me to use seperate subs in most cases when so many good full range speakers can be had on the used market. If nothing else, why not move up the line of your speaker brand of choice, it will likely cost less, be more aesthetically appealing and easier to setup the gear to boot. I also have to imagine that if 75% of your music is better with a sub then you must have very limited range monitor speakers, which is not the case with the originator of this topic. I'm just offering my opinion, take it for what it's worth, just as others will take your opinion....
