Selenium D250x? or CDT Audio EF-61CF/TW-25

Does anyone know if these horns are worthwhile?

I'm gonna tell u what i have and what it's doing so if u got any other recommendations, let me know.

I have 2 ID 6.5s in the front and 2 ID 6.5" midbass woofers in the rear.

They are all ran off of a sundown 100.4

I had first set the HP for the fronts around 300hz and the rears were bandpassed from 50-400hz.

When i had it setup this way, the rears were 100% inaudible.

I have redid the x-over since then i have it setup something like this-

fronts are HP at 700hz and rears are bandpassed from 50-800hz.

This makes the music sound more deep and rich-like but because there is so much range lost up front, there's quite a few songs i listen to that were actually louder with the stock speakers ran off the head unit!

Though, the majority of the songs, i'd say about 80% are louder with this setup.

Well, recently, when i was running 1,300w of amplified rated power, the bass to mids\high ratio was right at perfect for my tastes.

However, i'll be bumping up to 4,500w soon and i know i'm gonna fear a "drowning out" environment.

So... i need help! I do NOT want to change or add amps, i'm only gonna stick with the Sundown 100.4 and have some questions of choice i can do unless you know of anything else-

1 -

CDT Audio EF-61CF/TW-25 rated to do 175wrms with musical peak power of 320w. I could buy this set and bridge it on the Sundown 100.4. I believe they could handle the 320w from the sundown hopefully... is this enough?

2-

Replacing the rear fill with 2 Selenium D250x Horns. I know nothing about using these and cant find any reviews either.

The price is scary low but the specs make me wonder-

100wrms, 400hz-9khz, 107Db efficient... $70?

When using horns period, the ONLY way i can use horns is if i mount them behind me directly towards my head about 3-4ft away. Is this acceptable or a very bad imaging idea?

This is the only things i have to choose from.

The Selenium D250x is a midrange driver with a one inch throat. You'll still need a horn. You would have to figure what horns are recommended for the D250x driver, and what type of horn will work best for your application.

I've heard the D405ti with some rather large constant directivity horns once, they are huge drivers with some ungodly sensitivity and power rating.

I could only imagine a pair in a car (van?) with 100 watts to each one.....that'd be loud as f*ck.......

In fact I recall looking at the Selenium D250x once when I was shopping for midhorn drivers for Klipsch LaScalas.

They would make a good cheap replacement for the Klipsch K400/K401 midhorn, as opposed to the K55 Klipsch driver. (Atlas)

I did end up finding a pair of K55V midhorn drivers locally.

well, how does one go about knowing what horn works better for a certain application over another?

These selenium d250x are being sold on ebay and sell in 2 or 3 different horn shapes.

How would one know which is right for him?

I've also heard that horns sound different than speakers... how so?

What sort of application do you have? Would they be mounted on a wall or something?

I guess one would have to figure what type of dispersion pattern the horn has, and what pattern would work best in a car enviroment. Which is more or less nearfield I suppose.......Getting things sounding correct on axis and off axis are something to maybe think about.

I dunno....most those horns (I would assume) are designed for public address/sound reinforcement applications, where you are more than 3-4 four feet back from the speakers/horns.

never done a set of the EF's although we do have some at the shop. are u looking to put them in the back as well. The only issues im thinking of is with a 80hz crossover and 300w somethings gonna blow. you may want to look at some dedicated midbass drivers in that case

yea, i'm just tryin to see if these things can actually work in a vehicle or not.

They would be 3-4ft behind your head in a 2door car if i were to install them.

Does that throw the entire Front Stage off by installing them back there or no?
