Take a key chain. Cut it in the place where the ring completes the circle.( I am talking about the ring of the key chain) At that point, there will only be one wire. Once you do that, you will 2 "C" shaped ring like the Halo's.( you may have to clip it widen the C shape) Now put in any type of dampers to slide over the ring and ensure it touches the tube. The gap in the ring is important.
You are business.
I took a silicon tube, taped it with teflon tape and it looks expensive !!!!

Shreek, how do you like the DFR8 in the ZOB so far?

Ok. I still think the design falls short in the mid bass area. You will need a sub to make it sing. Yes, it does give a nice stage and in my set up, the entire stage is behind the speakers. It images well, so with the open sound, its quite impressive. I have tried various slot opening options, but still feel the design or the drivers need some help. The new drivers at $600+ does not justify a DIY approach.I am better off with a sub, rather than adding a new driver and then finding that I still need a sub.
But having said all that, every time I listen to my second system, which has the Lowthers, I feel that the ZOB does not have the magic. The Lowthers are in a different league altogether, irrespective of all the mods done on the Fostex.

Shreek, I know what you mean. I used Audio Nirvana drivers for mine at first, and I can't really remember that well what the sound was like. I do know that I wanted something more. I waited for the FRX2 to arrive, and as much as I like it, I agree with your assessment about the bass. I will say the FRX2 puts out quite a bit more bass than the AN did. I also use a sub on some music or DVD soundtracks with good results. The speaker really doesn't need that much help. One big advance is source material. SACD's have really impressed me with their quality, and these speakers are worthy of them. One more thing, I did add a tube based buffer amp to my setup, and again, a change for the good occurred(in the mid bass).

Here is how I build my tube dampers. They are actually rather slick looking once they are on. http://co-bw.com/DIY_Tube_Dampers.htm (http://co-bw.com/DIY_Tube_Dampers.htm)

They do look good! - Kind of bolted on. Hose clamp look.

That's pretty clever, Yoder. I like the look.
Fortunately for me I haven't felt compelled to go there with my Ultimate Quickie. ;D
Lining the box with Dynamat Extreme really did the trick.

A "stainless steel hose clamp" look at that!

Inspired by an earlier post, here is my attempt. Got those from the local hardware store. Those are water pipe clamps with rubber on the inside. CHF 3,70 (that's about $4) for the two of them. Microphonic reduced quite a bit, but not totally gone. The frequency causing the microphonic ringing changes with the amount of tightening the screws. So I will play around with it a bit.

Love the red plate.

I like the look much better, and i think it may have greater contact area.
