SDA-1B's with Heil Tweeters Do-able?

Posts: 201
I just picked up a pair of ESS AMT-1 towers with Heil tweeters ($50).Woofers were shot so figured I could try the tweeters on the SDA's.Apparently they're 4ohms.I'm not a tech so need to ask if I need to change the crossovers and how,or can I hook them right up?How would I wire the two onboard tweeters to the single Heil?

Trust me the answer is no. Even with good XO modeling software, an SPL meter in a good environment, lots of experimenting, and luck you would have so much time/frustration into it. Just get the RDO's, new caps and resistors, and be done with it.Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
Thanks

Can you tell me what RDO means? -
I bet you could get a good buck for those Heils if their still functional.
As mentioned you would need to completely re-engineering the crossover to use them in your SDA's.Testing

Geez you guys! -
Those AMT heil tweeters are gold, They sell regular on Ebay for over 200/ pair. And the AMT 's had room shaking bass and are desirable but very power hungry, refoam them , sell them ! And put the money into your Polk system with updated tweeters and caps and coils if you can.

I'm guessing ,Ring Dome something ...
From what I understand, the SLxxxx series of tweeters was named after the Polk Audio engineer who developed them (Stu Lumsden ?). I am nor sure where RDO came from.Stan

About $300+/pair actually...I generally don't like to let go of gold when I find it so may put these on display till I can figure out a way to use them...perhaps bi-amped,after i've learned more.Still in the process of recapping,etc. my amp....Will have to practice PATIENCE!!! and remember to practice PATIENCE!!!

So what are the best RDO's for the SDA -1B's?Anybody got a part number??

Is it possible to get a capacitor/resistor upgrade "kit" so that I can skip all the searching/choosing/head scratching advice etc..and just get the job done?

You can pick up any small amp feed it with a small capacitor in the input, ( very small cap. google for high impedance crossover points) and just set the whole tweeter on top and see if it helps !
