Crossover? Building - Scanspeak 9700 and 8545

[deckerluke]

Hey,
I'm looking to do a new design I've been working on for a Scanspeak 9700 and Scanspeak 8545.

I'm trying to get help designing a crossover but right now have been looking at the Madisound Solist as a possibility. I would like to customize my own crossover with my local tech (but must get a basic idea of what I wanna work off of)
any suggestions would be appreciated!

I am looking to make my monitor based off the dimensions of the Pro Ac Studio 100.
These components are essentially an upgrade on that model's.

(8543 and Scanspeak 9500 modified by ProAc)

Hello,

It is not an easy task for a beginner.

I was going to direct you to the same place.

I've seen this. thank you.

My speaker is going to be significantly smaller

will the Solist crossover not work correctly for this set up?

I believe it is designed for the same combination

9700 and 8543

A good crossover is developed for a chosen set of drivers AND a chosen enclosure. For the enclosure the baffle width and the placement of the drivers are important, so I think that if you use the amish (8545+9700) crossover, and you retain the baffle width, and the placement of the drivers (from the top of the baffle), you are (more or less) safe. With a smaller enclosure you will have to change the bass tuning.

what's the benefit of using such robust tweeter with 3K crossover? some $5 buyout tweeter will be just as good.
I'd look for some other design.

 

[deckerluke]

are both the Solist's crossover design and the Amish's a 3k Crossover?

I'd be interested to know what you'd suggest as an alternative.

See Amish revisited, better crossover, 2.3kHz crossover frequency.

deckerluke, you may try to contact this person

I've seen some threads on this forum, where he helped people designing crossovers. I have not heard any of his designs, but by looking at his final responce curves and from some of my own experience with same drivers, I'd say his designs are quite good.

 

[deckerluke]

is the Solist's crossover also 3 k


what about the Pro Ac 100's? I can post the image so you can take a look..

Will contact Jay's diy lab, thanks for all the help!
