BH 5 damping

[kyrill]

Hi

Where in Europe is it possible to buy Black hole 5 via the internet?

An externally hosted image should be here but it was not working when we last tested it.

No advice?
Nobody knows of BH5 or is it not of interest for European speaker builders?

 

[sreten]

Well IMO an equivalent to BH5 is not difficult to knock up using
cheap vinyl floor tiles, structural foam and acoustic foam.

Personally not convinced about the " septum barrier" when used
in a loudspeaker but it it does make sense for large wall isolation.

Its not sold in the EU as far as I know.

Parts Express sells Black Hole. You might want to check if you can get it in Europe through them.

don't underestimate the "power"of BH5
It is thàt good.
Zalytron is cheaper and from NY which is "closer"to Europe regarding shipping costs. It is the shipping costs that is expensive as BH 5 is very heavy Unless you choose for surface shipping (by boat, 4-6 weeks)

BH5 is quite heavy stuff. I had considered buying regular foam, and then other dampening materials to try to make my own version of it, but after calculating all the costs, I decided to just buy BH5, as it is very easy to use with the adhesive backed sheets.

It took me 5 sheets per speaker (12"x18" sheets from Parts Express)

Good luck finding some in Europe. It is distributed by the same company that distributes Focal, PHL and Raven.

Hi Brian

I have an almost similar choice as yours.

Focal 10W 6452 woofer http://www.zalytron.com/pictures/10WSpecifications.pdf

Focal Audiom 6wm their current best midtrange (preferred x-over 200hz) and a Raven substitute

Aurum Cantus G3, sorry for the moving picture

Sounds like a great combination. I was considering making a 3-way with the Raven R2, Focal 10W6411 and the 6wm, but didn't have the extra cash, and stuck with the 2-way.

How come you choose the 10W6452 over the 10W6411? It looks like the 10W6411 is newer and cheaper.

I hope it works out well for you. I am still considering the 3-way for the future.

Hi Brian

I got he 6452 for 170 $ and if you compare data they are almost the same.

 

[kyrill]

Still no answer

Nobody ever wanted to have Black Hole 5 in Europe?
How come, europeans do not believe that BH 5 is thàt good?

Yes I have a sheet

Fortunately I only need 1 sheet for my CAOW1s.

Mine came from www.sonicraft.com

Jeff at Sonicraft is really helpful. However BH5 is bulky and heavy so mine came by slowboat from the US. Took about 5 weeks.

While your at it, Sonicaps and Mills are very good.

I think that a combination of the usual materials will do the same as Blackhole does. The only difference is that someone else has already done the experimenting for you (hopefully !!).
