Good afternoon, gentlemen. We have made some serious strides with the mods I am doing to my Tyler Acoustic Signature Reference speakers. If you didn't know or you haven't read before, the crossovers are being upgraded and literally everything between the output of the amplifier all of the way to the drivers are being overhauled, upgraded and custom made to make these the best of the best of this particular speaker. With that said, I have ran into a decision I'd like some input on from those who might know more than I on the subject.
What we are currently looking at building is a custom made 3/8" thick aluminum chassis that the exterior will end up being will be one piece, with the exception of the access panel in the back. Custom outriggers and spikes will also be made to order and both the outriggers and the aluminum chassis will be powder coated in black. I have had a hard time sourcing Ribbon Mahogany panels and today, I just so happened to talk with a stone shop. I told them about my project and while they normally do not do things like this, they agreed to do it and actually went above and beyond the call of duty to be involved with such a project.
I was able to find a absolutely stunning piece of granite out of an extensive collection of stone. We were able to locate a 2C stone that was about a half inch thick, probably a little bit thicker that they will be polishing the facade, edging and polishing the edge as well. When I provide the template of the sides of the actual aluminum enclosure, they can insure an exact fit. Didn't think this was possible with stone but you learn something everyday. Here's a not so detailed picture of what I could find online of the granite mined from India [not sure which mine]. The pics don't do the actual granite justice. That or the slab I saw was just an extremely eye appealing slab from the quarry. There were a plethora of "tiger eye" type effects within the granite with colors that were off the hook.
So, I'm left with a decision though I'm not sure how it would affect the final outcome of the project. The crossover enclosures will be sitting in between the speakers and they will be low enough as to not disturb the MTM drivers. The estimated weight of each enclosure is already at around 40 pounds give or take and since they both will be isolated from vibrations with each internal circuit isolated from each other on shelves made of Delrin, I do not think that the weight would be a factor but I do not know for sure. Here's my question now that you know the facts...
With the knowledge above, what would you use....solid Ribbon Mahogany [If I can locate 4 (approx.) 30"x22" panels] or the aforementioned granite slabs and what would be some possible pros/cons of each type of material?
Thanks for looking and I'm open to any suggestions thoughts or experience you may have to share on the subject.
