Crossover Mods For RDO 194 Tweeters ?

Posts: 19
Just wondering if anyone will come up with a SLIGHT crossover mod for the RDO 194 tweeters ?
Yes, it IS a better tweeter, smoother, more extended, and faster then the stock tweeters.
But it seems to be SLIGHTLY more efficient in its lower range then stock.
This gives a slightly edgy sound in female voices.
As the RDO 104 tweeters break in, they get worse, meaning they seem to play even louder in their lower range.
Anyone else noticed this ?

Nope. I love mine. Made everything in my SRS II's, SDA 1C's and SRS 2.3's much mo betta.
What kind of equipment are you running them with and which model speakers are they in?Richard? Who's your favorite Little Rascal? Alfalfa? Or is it........................Spanky?.................................Sinner. -
I love them in my 2As. How much play time have the tweeters gotten so far? Over 50 hours?
-
Well over 200 hours.
I have tried several amps and preamps.
It does not matter, the peak is there, or maybe it is a slight level mismatch ?
I can hear it on quite a few female voices. -
Not knowing which speaker you have It's hard to say exactly what you could do. I can make a generic suggestion to first try several resistors in seires with the tweeter(s). Try a 4 and then an 8 Ohm resistor. Each will would reduce the overall power to tweeter. You could also try a 10-30% smaller high pass capacitor. That will decease the volume only in the low frequency operationg range of the tweeter. Of couse you can use the resitors and the cap change together to alter the overall tweeter volume and attenuate some of the lower end of the high frequencies going to the tweeter.
If you tell us which speaker you have I could check the XO schematics and be more specific.'65 427 Shelby Cobra

Hi Kapacitor,
I am kinda new to Club Polk so do not have all the answers. We have some great folks here and they will help you out. The guy from Texas (avguytx) asked you which speakers you have and everyone needs to know this for starters. Equipment maybe the next thing but from what I have experienced the crossovers need attention. Just replace the existing caps and resistors with high performance ones with the exact values and you will be happy as a pig in ****, just like me. Search the threads and you will learn alot and if you have questions the folke here will be more than willing to help you out.

The RD0194's were too dull for my old ears. I went back to the sl2000's in my srs's and 2b's with a 2.0 uf 200 v mylar capacitor on them. I'm using sl3000's in my 2.3's for a little variety.

I have SRS 2B's with RDO 194's.

I have SRS 2B's, the newer ones with bi amp crossover.Not knowing which speaker you have It's hard to say exactly what you could do.

My RDO 194's initially sounded dull, but as they broke in, they seemed to become a BIT too efficient for the midrange drivers.
I think there will be gains to be made by playing with crossover values a bit.
It IS a different tweeter,, and while it is CLOSE, it is not going to be exactly the same as what it replaced.
I still have my SL 2000's, and want to go into the domes and try damping the chamber behind the dome by filling it up with felt.
Several high end manufacturers of the late 70's early 80's did this to the old Peerless tweeters, smoothed em out. -
There is a model SDA 2B, but no SRS 2B. The SDA 2B only came with one set of binding posts, so you must have something else.Political Correctness'.........defined

It says SDA Signature Reference System 2 on the back, it is bi wired, mine is, with two separate runs per channel.There is a model SDA 2B, but no SRS 2B. The SDA 2B only came with one set of binding posts, so you must have something else.
I am thinking on playing with 24 gauge solid core wire for the tweeter part of the bi wire run.
Perhaps the thin, solid core wire will mellow the tweeters out ?
It has two tweeters per side, 2 stereo array drivers, and two dimensional with a big passive radator, about 4 1/2 feet tall. -

Where does the 2.0 uf cap go in the crossover with the sl2000? -

It sounds like you have SRS II's. I have the exact speakers myself. I was looking for a picture of mine after I redid the tops and bottoms but guess I don't have pics of them!

I am wondering if you are hearing more from the Mid/Drivers. My mids became much more defined and transient response went through the roof after upgrading the crossover.

No, I swapped the SL 2000's back in, and the RDO 194's are louder.I am wondering if you are hearing more from the Mid/Drivers. My mids became much more defined and transient response went through the roof after upgrading the crossover.
Maybe what I am hearing is an aging Capacitor in the crossover ?
It may be the RDO 194 is just revealing what the aging SL 2000 hid ?
But what I hear is what I hear.
Sorry to report just dropping the new tweeters in did not make me see God.
Perhaps with a crossover parts change Jesus will appear ? -
Where does the 2.0 uf cap go in the crossover with the sl2000?
On the positive wire to the tweeter not on the crossover (i.e. right behind the tweeter).
Pic added. Looks like a 50 V instead of a 200 V. -
My SL 2000's did not have a cap hanging off of them, was this an added mod ?
What speakers and why did you do this ? -

Yes I added the $3 cap. to my 2b's and srs's.
I could tolerate the sl2000's until I went to solid core speaker wire and then they got too bright but with the cap, they are just right.
