Granite Tower Speakers

This is the first post of what may be a very long story. My plan is to build a pair of Dynamic 4TSE entirely out of granite.  Before I get into the details, let me introduce these 3-way tower speakers designed by Jed Kunz of Clearwave Loudspeaker Design. Each cabinet is comprised of the followingContinue Reading

Some Rethinking

Some Rethinking

Let me list the challenges Weight: Each cabinet would weigh approximately 250lbs The flare on the port is wider than the rear panel, encroaching on the “end grain” of the side panels.  There is no way I can flush mount the port.  See exhibit A. Flush-mounting the drivers.  My thought was to use a 3CMContinue Reading

I will be ordering the crossovers, driver, and odds and ends from CLD on Monday.  With the drivers actually in hand I should be able to more easily finalize the drawings. Even without supporting any weight other than their own, the three points of 1/8th inch thickness on the baffles have me concerned.  Apparently itContinue Reading

Coming along

Coming along

Well, I’m still sorting out some of the construction details, but things are coming along.  I have everything in hand except for 7 of the 8 woofers.  They should be in sometime early next month. In real life the crossovers are not blurryContinue Reading

Almost ready to cut

Sent the drawings to the CNC shop a couple towns over (found one closer).  I designed the inner baffle for the woofer to accommodate any slight production variations that may be present.  My main concern is cutting the granite baffle correctly.  That won’t be drawn until the cabinets are assembled and all 8 woofers haveContinue Reading

The fabric arrived.  I’ve done some glue tests on a few MDF scraps.  I think it will hold sufficiently with 3M Super 77.  But the edges are going to need some reinforcement.  No matter what I try, I think the edges of the fabric will peel if not covered.  If not in a month, thenContinue Reading

Parts Cut

The CNC work is done.  I will pick up the parts in the next few days.Continue Reading
