Two subwoofers??

I'm assuming that you are looking at 2 subs for a home theater setup. For a home theater setup, you would want to get a larger sub like a 15" or an 18" for more slam/boom in crashes and explosions. These larger cones tend to be more sloppy and slow. (the larger the surface area, the slower it is going to move and stop). If you are looking for a sub for a musical setup, the smaller the driver the better. (most decent speakers do not need a sub for music in the first place. If you have the right room, the right setup, and a decent 2/3/4 way speaker, you will get a more true-to-life sound than emphasizing the bottom end. For example, read reviews of the famous Revel M20 small monitors, the reviewers indicate that they are not missing anything and prefer the sound of the M20's without a sub). If you think you still need a sub, try to audition one that has multiple small drivers which will be faster and more accurate than that of a larger more sloopy driver setup.

Search4tas must be smokin something to think he's not given up a thing with his small 2-way M20 monitors. If that was the case, Revel probably never would have made the Studios or Salons which in my opinion are way better than the M20's. And the stuidos and salons prices which is 5 to 8 X's the cost of the M20's would certainly make us believe that at least Revel thinks the other speakers to be superior to the M20's. Especially in the lower regions.

Search4tas also misinterprets the reviews of the M20's. The reveiw in Stereophile says no such thing. Only that the M20's sound bigger than they are.

S4T's comments about the subs being sloppy, slow, crash, boom, bang are almost as obsurd as his other comments. There are good and bad subwoofers big and small. I've heard as many smaller subwoofers with no musicality as I have heard larger subs.

I have certainly gleaned alot of good information from the follow-up threads to my original question. After reading all of them, I have come up with the following:

1. Everyone seems to agree (except for Search4tas) that I could certainly benefit from two subs. Let me clarify, that I have auditioned the M20's, and they did have a great bottom end for a mini-monitor.

2.The end result from the use of two subs is heavily dependant on room placement and room dimensions / layout.

Let me put another question out there then. My previous question and all of the resulting threads assumed that I would use two subs with 8" drivers (as I stated that speed was a priority). My question then is this: What about two subs; one with 8" drivers that would be x-over to kick in between 80Hz and 40Hz and a 15" sub with a x-over to take over lower than 40Hz. This would require an external x-over in my setup, but would negate most of the sub placement problems. Anyone tried this????

Thanks for all of the great info so far......

I don't see the need to use three subs as you suggest because the Velodyne frequency response is flat from 100 Hz down. Using two subs for the front channels and a third sub for the home theater channel would be sweet if you have the budget plus floor space.

I was not suggesting using three subs. Let me clarify. I have B&W CM2 speakers for the front and surrounds. These are great speakers if only a little light on the bottom end. To fill out the lower end, I now have only the one sub, and am exploring the idea of a second sub. My previous thread was to inquire if anyone had tried a two sub arrangement that used a large driver sub for lower freqs (40Hz and below) and a smaller driver sub for the 80Hz to 40Hz range.
