Hooking up horn tweeter to custom Fostex speakers

[big_shooter]

I purchased a pair of custom built speakers with 4" full-range Fostex drivers(A). They were built with two sets of binding posts to add an external tweeter.

They sound good as-is but when I hook up a sub the highs are a little light. I'm thinking of adding a set of Magnavox horn tweeters(.

Here is an illustration of my set-up. Is this the correct way to hook them up?

Thanks for your help.

Yes that will work. However, you probably need a some type of filter to prevent low frequencies entering the horn.

Is this my best option for proper hook-up?

What kind of filter am I looking at?

This is my first encounter with full-range speaker options.

Thanks

I just realized what you meant by filter. Basically I need to hook-up a passive crossover.

This should be interesting. I'm sure there is tons of DIY speaker instructions online.

Yes. At minimum I would place a capacitor parrallel with the + line going to the external tweeter. Maybe 4000hz or higher. You might have to place a L-Pad on the tweeter to match output of the full range driver as well.
