Who makes custom sized BB & granite slabs?

Well, I've added the granite slabs and updated my system thread with some pics and comments. I am still playing with speaker placement, and will comment further here after this coming weekend...

Thanks all. I suppose trying to have something cut locally makes most sense...

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...

That Timbernation is nice stuff.
I sent him an email for a price qoute on some black lacquer platforms. Thanks Bigbucks5...

Still no word from this guy at Timbernation. I left him voicemail today...

I finally got a qoute from Chris at Timbernation via email today.
$140 w/o spikes, $170 with spikes, black lacquer maple (see dimensions below).

I've also been looking into granite while waiting on Timbernation, and after talking with Gpdavis1 he suggested buying local as freight charges may be in excess of $300 for granite. After some legwork, I found a local shop that is going to make me granite platforms in Absolute Black, 26" x 16" x 3/4" with soft rounded edges/corners for $140 apiece. This dimension will give me a 2" border around the base of the speaker, and the soft rounded edges will tie in nicely with the "skirt" at the bottom of the VR-4's. One reason I decided to go with granite is the 3/4" thickness vs. 2.5" for the Timbernation platform (1.5" spike, 1" board). This combined with bearing height would jack the speaker up quite a bit. Besides, the granite is frigging beautiful, and heavy! If the tweeters are too high, I will angle the M/T unit so it fires down at the listening position using sorbothane bumpers (I'm not so sure this will need to be done though). Once slabs/speakers are in place I'm going to "revisit" speaker positioning. I will then level and let settle, and possibly relevel after settling. An audiophile bud is going to bring over his Aurios Pro-Max bearings, so I don't have to shell out the dough for two more sets just yet. It's going to be a long process as the shop is three weeks out, then all the tweaking. And finally, we'll see (or hear) if having the speaks up on bearings is worth all the frigging trouble I'm going thru!@#$%&! Why do we do it to ourselves???

All kidding aside, it's a fun project that I'm looking forward to,and if nothing else, I'll spike the speaks to granite with Audiopoint disc's in between and it will look really cool...

Don_s, will do...

Sounds_real_audio, these slabs are being cut, edges/corners rounded and fully polished from a single piece of waste material. I feel that @ $140 per slab that it's a pretty fair price given the fact that I can't whip these up in my garage. I did contact two other granite outfits here in the Phoenix metro area and neither one wanted to do this for me.
