New HDS

5th element · 11th February 2005, 12:54 PM

Has anyone else noticed those new HDS series using PP and paper nomex? Id certainly like to try out some of them, I wonder how much they will cost when they are available. Does anyone know what nomex is actually like? is this similar to a carbon fibre impregnated cone?

its the fireproof fabric they use in racing overalls, but i havent heard of any structural applications of it

The last line of subs that eD offered used a woven nomex cone. So its looks quite a bit different than than HDS cones, but I imagine you are right in that they are similar to carbon fiber impegnated cones.

Nomex paper is commonly used in electrical insulation and loudspeaker parts, to name a few applications. It's not quite the same material as aramid (kevlar). Google will satisfy any curiosity

I asked my supplier and he said he could get them but might take a little while as not in stock yet.

The 830883 (180mm) nomex cone is about 1.6 times the cost of the comparable 6.5in from before. Due to my inexperiance I am still going with the older HDS speakers incase i run into crossover difficulties etc but would like to try them in the future.

I wonder if the cost is 1.6 times simply because he would be getting the units especially for you? or are they going to be more expensive anyway, I cannot see why though. I would imagine a sandwich cone is harder to make then a paper/nomex one, the only difference I can see between the original HDS and the exclusive series is the cone material, the basket and the colour of the phase plug.

Check solen.ca - I don't know if they actually have them, but they do have prices listed.

In an act of necromancy, I will note that HDS Exclusive is available. Has anyone heard the 106mm 830881? I'm interested in it, though the efficiency is damn low, and I need to know how much power it will take because the spec sheet doesn't say.

Hi guys!

I have some questions about Peerless Exclusive series:

1) Something is known in occasion of release HDS Exclusive with black color of a frame? In general D-S-T plans to do it?

2) Nomex fiber cone that from itself represents? I have in view of what the membrane is made from pure Nomex or all together with paper pulp or maybe even the paper goes as a basis ("Nomex paper" as has told bzdang?)

3) Hearings go that HDS Exclusive a series is removed from manufacture

Who can clear this situation.

Look at John Krutke's site for his review of the 5.5" Peerless 830882 right here:

I'm also working on a project involving the 7" 830883 and the Vifa XT25TG-30 tweeter. Hopefully I'll have some images posted soon.
