Hey gkannan,

Yes the heavy vinyl tiles are ideal. And you can place them on the outside of the cabinet if you want. You will have to figure out a way to glue them on.

You can also upgrade the cap and resistor used in the woofer circuit.

I think the speaker terminals that you are referring to are these: http://gr-research.com/electracabletubeconnectors.aspx  Read through that material. It is very enlightening.

Hallo
I just did internal bracing on my Elac B6 becouse the problem with resonances. I think that the resonances are gone now.

So now that many of us bought the Elac Debut 2.0 B6.2 on sale, any plans for crossover upgrade kits for them?  :green:

From what I've read the 2.0 went for a flatter response with the tweeter, which solves one of the big criticisms of the first run. Maybe all the 2.0 needs are decent caps on the tweeter.

The one that *really* begs for a crossover upgrade is the Elac UB5, which was on sale for only $350/pr (!!!). THAT I think has the most to gain from some basic upgrades.

I was just talking to Dan about this today after I read this thread. I'm planning to send him one to evaluate.

I did my updates a few months back with all the new Sonic caps and Mills resistor and also I used small 4"X3" kitchen tiles and glue to strengthen the baffle and eliminated the resonance. Put some Sonic barrier from Parts Express instead of No Rez and use the rest of the poly fill from the original box. The box is very heavy now.  I mounted it on a hollow tube metal stand and put some sand inside it. Also, I took off the beauty ring and the tweeter screen. It is now a very good sounding ELAC Debut B6. It elevated the highs which good for me and the lows also. I have the Marantz Pre amp and Emotiva Power Amp that is running it. I am very happy with the outcome. Thank you Danny!!  I will be waiting for what Danny will come up with the Elac Debut 2.0 B6.2 and/or the Elac UniFi UB5 evaluation.

Hey, I tried the Sonic Barrier product. It doesn't have a damper to eliminate or control cabinet resonances, but you did add floor tiles and that will help in that regard.

However, the suspended barrier layer tends to mass load the driver in the upper ranges. The result is a muddy sound in the mid-range. Pull that stuff out and just use some fiberglass insulation and it should open up the sound of the mid-range.

You can also buy  sheets /  sometimes smaller pieces of 1" Open cell foam  from   foam outlets.  Use some spray adhesive to attach it tothe  floor  tiles on the side panels.  Leave  an inch or so clearence for the  drivers.
I used to  do this  until  I tried the no-rez....  so much   easier,.

I will try to remove the suspended barrier and use the fiberglass insulation.  I may be replace the Sonic Barrier with No Rez if that will help.  Where can I get the No Rez?
Thank you for all the assistance.

You can order the No Rez right from our site: http://gr-research.com/norez24x27sheet.aspx

But if you already added some floor tiles then that will help quite a bit over how they came form the factory. Just removing the Sonic Barrier and adding the fiberglass insulation alone should really help. The No Rez will take the resonance control up a notch.

I will try to remove the Sonic barrier first and see what happen. If that helps then no need for the No Rez otherwise, I will get the No rez from your URL you mentioned here.  Thanks a lot Danny.
