Panzerholtz source for speaker cabinets in the US?

Look at Richlit

An example:

@planet10 ,
Dave, have to ask how do they sound?
Compared to lets say MDF or Birch ply?

Thx

Note: Both the Richlite and Panzerholz are cardboard (richlite) / beech ply (panzerholz) in a resin compressed and heated while setting.
There is a way to densify lumber by boiling it in a chemical bath to remove componets of the wood where you could then press and bake the wood into 1/8th its original thickness. Then use those as plys in a resin made panel. (Or something like that. )

There is a couple of YT videos on this... and a research paper... but I haven't seen or heard of this being done outside of initial experiments. Kind of expensive and not sure if it would be economically feasible or have any real advantage over existing products.
 
Yeah from the company I think they range in price baysed on thickness. The 1"(25mm) partial sheet is $288 for the bamboo.
Of course if you're going thru a distributor YMMV.

I've seen Richlite used for front baffles but not whole cabinets because of the price.
 
Precision Composits cut some very special Panzerholtz for me. Ive purched sheets of B18 and B22 before and it's not especailly attractive. The suff Precision Composits supplied could have been buffed and used "as-is" ub most formal spaces.
There are a couple of speaker companies in Germany that use Panzerholz where they add a veneer ply on top of it.
Linkwitz store sells the LX521 baffle in Panzerholz that is sandwiched between two aluminum sheets.

Its nice to find at least one source here in the states.
 
@msegel -- the speaker that @planet10 posted above is mine, he designed the cabinets. The pair is made of stranded bamboo ply, no richlite at all. Prototypes were made of baltic birch, they sounded great -- the bamboo took them to another level. The internal bracing matrix that @planet10 designed was also changed from baltic birch to panzerholz, this again took us to another level. I have been beyond pleased with them, and am now looking forward to adding stereo subwoofers to the system. Obviously, I am biased, but others who have heard the speakers have also been very impressed and feedback has been overwhelmingly positive.

Ah that explains why it didn't look like their offerings.
Thanks for posting.

Its great to get some feedback on how 'exotic' materials can improve the sound.
(exotic meaning something other than MDF or Birch ply. )

I like to see experiments w materials to improve the speaker cabinets.
I'm sure working w the bamboo ply and Panzerholz is easier than something like Granite. 🙂

The drivers/crossover make the sound.
But if you need to imagine a better sound by spending more money.
Send me money then imagine it.
Braced plywood with absorption material. All Done.

Funny how many " exotic" speakers just have horrible center to center spacing and crossovers.
But the expensive material makes them " sound better"

Hopefully whatever design being made is even worth it.
Since marine grade plywood already too expensive is more than good with bracing.
Being the bracing, driver placement and crossover have 10x more impact on the actual sound.
 
@WhiteDragon ,

Have you ever played a stringed instrument like a violin or a cello?
From your comment, I'd have to say no. Otherwise you'd understand that the cabinet affects the sound too.

You also ignored the shape of the cabinet. Size, Volume, shape of the chamber or is it sealed, ported, a horn, etc ...
All impact the quality of the sound.

You can take the same driver.. .lets say a full range. and place it in different cabinets ... same shape, different material, and you'd get a different sound from them. Including measurements.

To each their own I guess.. But have to ask... if you're so much against using different materials than MDF... why are you even in this thread?
