Dueland CAST PIO

Thanks for all the inputs from the owners of Dueland. I am trying to upgrade the crossover of Vapor Cirrus Black.
I already got the Amorphous RAAL tweeter upgrade, but was wondering if the crossovers were upgraded to the Duelund CAST, if it would make a difference. Ryan over at Vapor Audio suggested that the cap upgrdae to dueland will give it less than 10% of the sound imporvement, but I will be able to tell a difference. The price for the caps are $2,500+.

$350.00 for a single tweeter and $850 or so for the single woofer.

Not sure if both the Woofer and the tweter have to be done together, I will E-mail him tommorow and find out.

I have heard speaker with the Duelund CAST upgrade today, and the violin sounded fantastic.

If somehow I can get the Duelund CAST just for the tweeters that would be sweet, but I would have to check with Vapor audio on that.

Or, do you guys know if they have to be upgraded together?

What types of capacitors are in the speaker now?

Ssos101,
My crossover only has one capacitor which is at the tweeter and as I wrote
earlier the change was significant. I would speculate that if you only
replaced the tweeter cap in yours you should still appreciate the
improvement.

Salectric asks a good question, if the current capacitor is very average the
CAST will make a greater upgrade impact than if you already have a high
quality capacitor there now. For me the jump from Solen to CAST is a large
one.Mundorf Silver/Gold oil to CAST a smaller gap change would be
expected. Which location has the greater influence on the sound, tweeter or
the woofer? My gut says likely the tweeter capacitor. What does your
builder say? The CAST are so natural, the music reproduced just becomes
more real and has increased emotion .

The jump from the Mundorf SGO is huge my friend as I have done it. Nothing special about that SGO Mundorf cap to be very honest. It is good, but a $10 JFX FB Premium film cap is better. Ya, I have compared both!

I would start with the Duelund caps on the tweeter. The improvement will be more than 10 percent and on the order of a significant amp upgrade.

Yes, do replace the tweeter cap first and enjoy for a while.

I have tried many caps and the Duelund CAST are special.

Your speakers are very good and deserve the Duelund touch!

On my 2-way vintage speakers, the Duelund CAST cap made a much bigger difference when used on the high-pass (tweeter) than on the low-pass (woofer). In each case, the Duelund was replacing a Mundorf Supreme (regular version) so this was a fair evaluation.

In general, if funds only permit upgrading one cap in a 2-way crossover, I would go with a Duelund on the tweeter since that should give the biggest improvement for the buck. In a 3-way crossover, things are more complicated. It's possible the midrange may benefit the most but the crossover will also be more complex so you may need more Duelunds.
