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.

Forget tiles or glass, etc. They are flimsy and breakable, with a relatively high resonant frequency. Get some corian (the stuff they make kitchen counters with). It's a resin product, very heavy and non-resonant. You can find it cheap at flea markets or through a plumber or contractor who cuts holes in it to fit kitchen sinks, etc.
You can have it cut to size, to fit the footprint of your speakers. Drill holes in the corian slabs and install spikes into them. Then put your spiked speakers on to the corian.
Great isolation, better sound.
