Who makes custom sized BB & granite slabs?

You can get 1.5" tick beach kitchen top butcher block at Ikea.
You can cut it and stain it the way you want.
Please, check my system under white room.

Here is a link for butcher block in 1 3/8", 1 7/8", 2 3/8" and 2 7/8" thick. Available in a wide variety of widths and lengths. I think they may even cut to dimension on request.

Here is where I bought 1 1/2" butcher block for my audio rack. They have an outlet about a mile from my home.

Good luck.

Lateguestsnomore, good tip on IKEA, and nice setup you have there.

Don_s, perfectplank may be my best bet yet.

Here is what I'm thinking of doing, and perhaps you'all can tell me if I'm wasting my time and money. I'm a big fan of isolation bearings, and have always wanted to put my speakers on bearings. I have been told by a reputable source that this makes a huge improvement on the overall musical presentation. Only problem is, I'm on carpet over cement slab. Bearings and carpet don't mix obviously. So I need a base or platform. Was thinking granite or marble, but floor is not perfectly level where speakers sit, so would have to be shimmed, which can be done. But I was thinking a butcher block platform with leveling spikes to concrete would provide a nice level and stable base for bearings and speakers. Perfectplank has precut 24"x12" planks in various thickness, which would be a very good fit for my VR-4's. They also custom cut mahogany planks.
Check out my system and give me some opinions please...

Driver has definitely got the granite part going on - not custom, but there is the savings - its a Henry Ford thing, any color so long as its black - I have ordered from them several times and the service and product is top notch

I finished the last group of blocks (for mass loading) with cork from McMaster Carr
