Mini Onken dampening
I'm building a pair of Mar-Kel70's with Generation 1 Mark Audio CHP-70.
The drawing states that all internal panels should be lined with 12 mm wool felt, 19 mm poly-fluff batting or 25 mm fibreglass. I attached 12 mm wool felt to the insides of: - Floor - Roof - Back panel - Sides. On images of complete flatpacks, I saw images where the insides of these panels are lines: - Floor - Roof - Baffle - Sides for 3/4, where the last part before the ports were not lined. Not the back banel is lined; I thought for reducing standing waves etc. this is the single most important panel to brace... What is correct? Really all panels, my idea of all panels or the ones I saw on an image? |

It does get to be a bit of a logistics challenge with the smaller enclosures, but I always line all interior panels, avoiding occlusion of the internal opening of port slots with an approx 12-15mm margin.

What Chris said.
As well a less dense pad can be attached to the holly brace (the side that is on the centre hole -- and covering the holes). dave

Guys, thanks for the replies!
So lining of the back pannel and also the baffle are needed? (In addition to top, bottom and sides). Luckily the first cabinet I closed down has almost all of this lining in. Only the baffle and the brace are still 'naked'. |
