Yep, I think it should work just fine with the Polks & Sonus Faber.

Thanks . You have really helped me out with this. I appreciate the input.

As for your townhouse issue, you may need to isolate it more than the included spikes. Auralex Acoustics makes a sub isolation product called Gramma. You can find info about it HERE . Check the dimensions, you may need two.

I use the Auralex Mopads for my center channel speaker and they work great.

I checked out the Gamma. I see where people like the way it improves the bass but does that help my neighbors from calling the cops on me? :p

From what I can tell, it should serve to decouple the sub from the floor, such that the sub would not induce vibrations in the floor. That will keep the neighbor's floor from vibrating along to the beat (or at least reduce it), although it won't help any with sound passing through the walls.

Okay. That might be worth checking out. I saw it on-line for about $49.95 so not much to lose and I am sure that the neighbors will appreciate it. Thanks again, you guys rock!

One thing I forgot to mention..I noticed with the Velodyne that I always knew where the bass was coming from. It was very localized. Is that due more to the acoustics or the sub do you think? Will the LFM's downward firing set up take care of this? I have tile flooring throughout.

We haven't had any trouble with our LFM-1 being localized.

What are your current bass management settings? If the crossover point is too high, the bass is typically more easily localized.

Right now I have everything set at 60 since the Onkyo only lets you adjust all of the speakers to the same crossover. I suppose I will have to figure each speaker out now with the 950. Since I have 2 floorstandings for fronts and two floorstandings for surrounds it should be interesting
What is it on the speaker specs I am supposed to look at to figure that out anyway? The lowest overall frequency?

To figure out the recommended crossover point, check the speaker specs and look for the lower limit of frequency response at -3dB (for example, the lower -3dB limit on the Polk LSi15's is 30Hz). At very least, set the crossover above that point. Some people recommend going up one octave from that point (in other words, doubling the -3dB point) and setting the crossover there, but I don't necessarily go that high. For your mains, I'd try 40Hz and 60Hz.
