Subwoofer with 2 channel stereo setup

I agree with S7horton. That is, it will depend on the system, speaker / room interface and the type of music that you listen to. I would not consider it necessary unless you listened to a lot of bass heavy music at higher than average levels and / or your system / speakers were either lean sounding and / or not capable of extended bass at higher outputs. I wouldn't go this route unless you were completely satisfied with the idea that you were already obtaining optimum performance from what you've got. Adding more to a system simply makes it more complex and harder to set-up. I'm a firm believer in the "KISS" theory for the average enthusiast that isnt' technically inclined. For those that don't know what KISS means, it is an abbreviation for "Keep It Simple, Stupid" : ) Sean

For sure it makes a difference in certain systems! Integrating a subwoofer into a system isn't easy but it ain't all that hard either. I for one couldn't live without it. I like it so much, I've seriously considered buying a second one to run in stereo. Only question I have is..what brought you to the conclusion you have to spend $2000 to get a decent musical sub? The KISS theory works well too! :-)

Gmood1: What if your "mains" were solid to well into the low 20's or even lower? Could you live without a sub then? That's why i said that it would be system dependent : ) Sean

Sean that's why I said certain systems.The last time I checked the Aeon I only gets down to around 40 hz. I agree with you ...when I had floorstanders that could do this no sub was needed. Of course the bass was not as tight as it is now with sealed enclosures doing the low frequency duties.

I couldn't help myself ...I went ahead and picked up another matching sealed 12 inch sub for my system today. Can't wait to get it tuned in with the other one.
Now we are cooking with oil ! :-)

I have main speakers that go into the 20 Hz region, but setting the crossover at 80 Hz, thereby freeing the mains of LF duty, makes the system sound even more transparent and open, and seems to expand the sound stage while maintaining precise imaging.
