One woofer or a pair?

Can I be clueless, Clueless? I believe I can be... and I also can be curious too especially if I hadn't tried any of the woofer-speaker combos. In fact you might be right about no-sub effect and I would also wait for that answer that you expect. What about the vinyl records that are stereo but designed for the mono pickup as well?? ...

I also believe that giving a sub his freequency range you can improve your speaker's midrange(again depending on a sub quality). Now that's not a kid-stereo stuff.

I've placed a few more psych poems onto my thread a long time ago. There were a few abstract dreams but I didn't capture them to write them down -- hard to be in control while you sleep. Besides I don't smoke &%$^ anymore and a probability of the quality abstract dream is much lower.
Before I smoked constantly and saw the dreams that I couldn't understand, but after a while I've realized that I can get up and be under my control to remember what was going on... The 2 worlds that I was trying to live before cannot be successfully combined: one of them will have a success and the other will have a failure...

In my experience, the only way to get away with a mono sub is if the crossover point is exceedingly low, meaning less than 40Hz. Anything above that and you will be able to localize it. I also agree about the virtues of downloading; it seems to couple to the room better, but again will only work well with very low crossover points.

I agree with Kevin. During the x-mas season my REVEL Sub15 had to go from the right side to the left of the room (because its space was needed for the tree :-) ). Just this move changed my systems sound in a frightening way and I was happy when the season was over - at least in this respect.
It seems to me that it is a matter of your room how you think and act about subs in general.
Good luck!

From all above posts I think that if you're using a pair of woofers you can use them as a "sub-speaker" and give it to work with higher freequencies than 50Hz maybe even upto 200Hz.
