From Bastanis Prometheus to Atlas

[Clive]

Clive at some point it be good to hear the difference between the two

Assuming John you mean the Chrystals, for the first 200 hours for so they sound very "nice", certainly in isolation no one would complain about their sound. With more like 300 hours now I have loads more detail, extension, bass richness, presence and some better bass dynamics (has to be due to the upper bass). I'm not commenting on Bastanis bass drivers vs Augie, more on what the other drivers are doing higher up the spectrum.

There's a huge smile on my face! And I'm guessing there's more to come yet.

How's the deck btw?

Long story Clive

As long as the tweeter + has a direct route (ie not via a voice coil!) to the + binding post it doesn't matter how you get there. Same for - to the - binding post.

The Proms in comparison to Altas sound rather clinical. Really glad they are working well!

Hello Clive and thanks for your advice, much appreciated

This is what I thought was the problem. So I need to unsolder the Gemini tweeter wires and move the + and - to the first wideband driver, where there is a direct access to the speaker binding posts. Currently the signal is going through the first wideband driver and then to the Gemini Tweeter. I assume this is mixing the signal somehow .

I am sorry but I am hopeless when it comes to the electrics, give me a piece of timber and I will be happy, but there is something with the electrics that just doesn't work with my simple mind

I totally agree, the Gemini tweeter is overpowering with only one Bastanis wideband driver, but with two drivers in situ, something magical is appearing .

So is the Bass driver open back looks like it in the picture if so have you noticed what is the bass response. For me this is where the Augee really win out over the Bastanis bass speakers true Dipole creates very clean musical bass, but be interesting if they actually work as true dipole bass

Hi John.

As Clive wrote, the low bass is coming from the sealed woofer cabinets. They are punchy in deed . I tried once driving them without the baffles with a pair of XTZ sub amps and very high volume levels: the impact made me physically sick. Saying that the interior door opposite the woofers was banging and the windows were shaking from the pressure waves as well .

I have to say that I would be more than happy to use the baffles on their own without the sealed woofers for occasional listening.

You can simply take the capacitor wire and Gemini -ve wire straight to the binding posts if you prefer.

Hi Clive.

This is the way how it is shown it the Bastanis web page as well. Only problem is that I do not have enough the same speaker wire that Robert has used with the widebands. Would you have any in stock? It is just that I would like to use the same wire as the wideband drivers have been wired with.

The wire is nice, I only have a few short pieces, nothing long enough for your ask. I drew the diagram for Rob that way for simplicity.

There's nothing wrong with taking the wires to the widebands. I have the capacitor going to the +ve on the top wideband and the -ve tweeter connection going to the -ve terminal on the lower wideband. These connections then go directly to the binding posts.
