Help with Dayton Reference 2-way Project

coldcut · 19th May 2010, 09:19 PM

Hi all,

I bought the Dayton RS180 and RS28A on buyout couple of weeks ago. Intention was to put them in my car, but since I´m getting a new car with descent sound instead, I like to try them in a hifi setup.

A monitor would be nice, but size is not an issue. I have seen a few xo-designs and builds with these drivers, but mostly in mtm config.

Do you have any experience/ideas/concerns that you can share?

They are excellent drivers. You'd cross them between 1300 and 2200. I'd try 1800 from the graphs I see of the drivers.

HTGuide Forum - RS180 Modula MT - you asked for it, you got it!

cheers

Thanks for the reply!

Now, I looked closer at the xo used for the RS180 Modula MT, and it looks quite complicated. Not the build process itself, but the construction. A lot of components for a 2-way, with drivers that are fairly well matched from the start.

My philosophy is "don´t complicate things when the improvement don´t match the effort".

Any suggestions about this? Can the xo be made simpler?

You need to ask the DIY builder of that speaker.

He probably has good reasons for adding extra components.

You probably could go with a first order on tweeter.
The problem with the woofer is the aluminum cone. Very nasty.

Guess you´re right.. Well, bought some fibre board today, and will try the HT Forum project. Expect a report on how it goes..

A question about the xo.. If a need a 20uf cap, but can´t find one with that value, is there a difference using two 10uf or one 5uf and one 15uf?

If thats the case, what modifications needs to be done? Last edited by coldcut; 23rd May 2010 at 10:17 AM.
