Mar-Ken6.2m CGR build log

dimkasta · 11th December 2012, 07:46 PM

About a week ago I received a pair of Markaudio 6.2m speakers planning to use them as a second/test pair for my new projects.

After some reading and a lot of emails with Dave, I decided to go with the MarKen 6.2m CGR

I will order the plywood parts tomorrow (15mm thick and 7mm for the vent spacer)

For now I just played around a bit with the speakers connecting them to my AW120 just to make sure they are working properly. They sure do look pretty

Dimkasta,

You better start breaking in the drivers according to Mark's instructions.

dimkasta · 12th December 2012, 08:33 AM

Naaaaaah no hurry... It s for my test rig anyway, so I will have all the time in the world to break them in.
I ordered the plywood today. 15 euros for all the parts. I will have them tomorrow.
I need to get some nice connectors now. I was thinking to get speakon ones, but I am bored to wait for them, so I will probably get some plain banana/spade ones.
Oh and I have to find some nice damping material.

I managed to find some Visaton damping material and I found some nice, cheap and decent quality terminals.
I also got the plywood today but unfortunately managed to ruin one of the baffles while trying to route the inner angle cutout. I usually test everything before actually cutting the pieces but tonight I completely screwed it up...
I have to go get a new piece tomorrow. And I am too pissed off now right now to work on the second one... Plus I have to redesign and re-test my jig and I m too bored...

dimkasta,

The inner 45 degree chamfer can be tricky with a router at times; safe and easy way you can do it is with a rasp.

dimkasta · 18th December 2012, 07:13 PM

Nah I hate the rasp...

I just have to make better jigs/templates for the router.

In the meantime, I began gluing stuff

The back side is there just to make sure that the side is square. One of them is actually the ruined baffle

I managed to work a bit more on the speakers.

Do you think this kind of damping material thickness will work with the marken? Basically if we account the material required on the baffle there will no air left in there... I guess I should trim it a bit?
The material is from Visaton

Yes. i'd try cutting it in half. Or compressing it somehow.
