BB4-AL, Germany's new CHR.

[markaudio]

Hi Guys,
It's a busy day. Here's first build pics of the BB4-AL, Germany's version of the CHR-70 with an all-black satin finish cone and cap (sexy). For more details, talk to Thorsten (German language) or Nick for English at Blue Planet Acoustic (BPA) in Frankfurt.

I understand Nick will make the BB4-AL available Europe wide and possibly other regions. The BB4-AL will be part BPA's "Omnes" brand line-up.

Details aren't on these sites as yet but you can get the contact and enquiry information.

Yummy!

Suitably evil looking.

Evil? Rather sleek and sexy, I think.

Will these have the same specs and a similar price as the new CHR-70?


Regards,

Martin

These things have convinced me that Mark has finally joined the dark lords of the Sith. Which naturally means I love them.

One assumes from the above that they basically are a CHR70, albeit with a black cone & an Omnes label.

There is, of course, the white coned woofer to balance that?

Good point. They look good too. Mysterious, the ways of the force are...

Hi Scott, ummmmmmph, dark side of the force...... could be interesting! They might appeal to Darth Vador. There's a "tweak" on the cone to give the BB's a slightly more smoooooth tone. A tiny change, nice.

Cheers

Mark.

Hi Mark, whats so german about the bb4, that Germany needs an own version of the chr 70? More smoothness, you wrote - do we in Germany have to be more smooth ...?

Hi Sahranna,
Good question. Nick and Thorsten at Blue Planet Acoustic in Frankfurt evaluated the first model CHR-70 early in 2009. They liked the driver but wanted a tweak in the high range to create a flatter response. I'd already started work on my Multiform cone making process so the timing worked out well. Subsequently, the CHR models using Multiform cones have the flatter response including the BB4.

The BB4 has a "tweaked" rear suspension which gives a modest increase in constant linear oscillation at ranges 2.20-mm to 3.55-mm (1 way). I've done this to assist the growing interest from younger DIYer's experimenting with computer sourced material, DSP and Near-field applications via Chip and class D amplification.

I should let folks know that Blue Planet Acoustic has a CHP-70 driver with the similar rear suspension to the BB4 (0.1/50g@+/-0.075 stiffness difference). This driver can be recognised by its black frame. The first model CHP-70 has the cream coloured frame so its easy to identify the different models.

From memory, Nick will market these drivers through his "Omnes" brand line. I think Nick will make these drivers available world-wide but best to contact them direct: Omnes Audio Loudspeaker - Contakt

Cheers

Mark.

Hi Mark, thanks for your reply.
How does this increase in constant linear oscillation affect the "sonic síde of the tweak"? Does the Omnes CHP sonically act in the same way like the bb4?
