Help Bass changes from carpet to marble floor?

How does bass response change from a carpet floor to a marble/tile floor? I am relocating to Europe, so wondering what to expect. My speakers are Audio Physic Yara (downward firing bass mounted on a stand). The current listening room size is 20x10 and the new one will be about 22x11 feet.

I have been debating on adding a sub-woofer to get a "little" more bass extension. I am not looking for hard hitting bass but something warm that just fills in. I am looking at the ACI Titans or Force and they are much cheaper here than Europe. Hence, I want to make a decision before I move.

Any help would be greatly appreciated!
Don't buy a sub that you can't test in your room. Period. Wait till you get to Europe.

(Which is probably good advice for any system change--give a listen to that marble floor before you decide to do anything.)
The bass quality and quantity will probably be affected more my room size and shape than the flooring material. Unfortunately, the midrange and treble will probably suffer as the first reflection off of the floor will no longer be absorbed. This can really harden the sound and add glare. A friend of mine had this problem with hardwood floors and after farting around with the setup for a while I went to a carpet store and got some of those little carpet samples that they were throwing away. They are about one foot by two feet, some bigger, some smaller. I put one under the speaker itself and this helped, but the bigger improvement was positioning one in front of the speaker to absorb the first reflection. No cost and the think sounds just great.
The above responses are right on target. Also, keep in mind that if your system sounds best on a carpet, just buy yourself a piece of carpet whin you get there. I lived in
europe for several years--my 'base' was in Paris. Hey, you are going to
europe---don't worry so much about us A'goners---get a life and

So many places, experiences joys....don't worry about your music. My suggestion: unless you are going for more than a year or two, leave your music behind and get out and live.
