Floorstanders over Suspended Hardwood-Help Please

I have a pair of Silverline Sonatas that weigh in at about 120 pounds each. When I lived in my previous home, I used a set of four points under each speaker over a thick carpet and an equally think pad. I recently moved and these speakers will now be in a room with suspended hardwood floors. There is a berber carpet over a portion of the room and under where the speakers will be placed. With their weight, the Silverlines will drive the points right through the berber and couple with the hardwood. Bad.

I need to find a solution and have thought of three possibilities:
1) Find a very thick pad to place under the berber and use the points like before.
2) Use discs under the points directly atop the berber. Stable?
3) Get some 1-2” slabs of marble, using iso-pads between the marble and the carpet and points/discs between the speakers and the marble.

I have tried using slabs under other floorstanders over carpet and always found them to be less than rock solid in the vertical plane.

Do any of these approaches seem best, or are there others to consider. Please keep in mind that I do NOT want to spend several hundred dollars on platforms such as Sistrum, etc.

Thanks, AB, but I wonder how these coasters are different from any other disc. I could be wrong because I haven't tried this yet but I would think that points setting in this kind of coaster over the berber would result in a speaker that was no too solid. I mean they would tend to rock even a little from the speaker vibration.

Right now I have the speakers on the berber using threaded bolts with small rubber cups over the heads. They sit solid but I am getting a bit too much bass thump from that floor.

These Coaster are about the size of a Silver Dollar & about 3/8" of machined Stainless steel. They weigh about 4-5 oz. each, & w/ a 120# of load pushing on them will be level even on carpet! You will have to loose the BOLT'S & get youself some points, or spikes.

What are you considering "Suspended" hardwood floor?

Free-Floating Pergo/Wilson-Art/Armstrong?
Glued, or Snap-Together?
Or Nail-down 3/4" Tounge-n-Groove?
Or 3/8" Tounge-n-Groove Glue down?

Even if you are talking about a Floating floor which expands & contracts as one piece. It floats over foam padding which is compressed by the total weight. I honestly could NOT see your speakers walking/wobbeling off these coasters no matter how much Low End you are experiencing in this new room.

Depending on which mfg'ers points (points is trademarked by Star Sound for their Audio Points) you are using, any alternative strategy will most likely seriously compromise the sonic benefits of such Points(TM).

Not to mention the other alternatives will also look less aesthetically pleasing.

Therefore, why not carefully place the speakers into final position and simply do not worry about it. (For initial placement, do not use points).

Someday you will discover 6 or 8 very small dimples in the hardwood and you may wish to repair before you sell the house. Then again, nobody may ever notice.

FYI, 3 Points(TM) per speaker may sound better than 4.

-IMO

You have work cut out for you, setting them on carpet using 'coasters' will not give you the best performance. Try contacting www.mapleshaderecords.com and see about having their Conepoints made so they could screw into your speakers. Buggtussel (http://www.buggtussel.com/) also makes some nice brass feet, though expensive, that may work out. I do not recommend coasters on carpet.
