SDA SRS Model Question
foxboy
Posts: 9
I have two questions:
1. What SDA SRS 1 model do I have? Famous for no id on early models mine have the two flat lugs on the cable with these markings on serial # plate; SDA SRS 3451 (for right) and SDA SRS 4460 (for left). Anybody know my exact model?
2. I use them for 5:1 surround with SDA SRS 2's in rear. I use the cables for both fronts and rears. My question #2 is, should the right be on the right and left matching position of fronts? That's the way I have always used them and seems logical.
I am new to this forum, so thanks!

@foxboy,
Get used to it; @F1nut is a man of few words, but he is almost always spot on!
By the way, welcome to Club Polk.
Hold on to your wallet because you may feel the temptation to dive into the rabbit hole!
Which gets expensive!

Thanks everybody, few words were all I needed!
I have owned these for 13 years and the SDA SRS2 for 28 years, pretty familiar about the "rabbit hole", it really has been zero. It is all original but still sounds fantastic, so if it ain't broke...They have always had plenty of power, original owner used 1000W mono blocks, I can run 550 watts at 4ohms, very undamaged. I am not sure I can gain much with $$, I enjoy them very much. Use a Klipsch RC64 center to keep up with the SDA SRS's. I built a 6cf subwoofer using a Altec 15" forget which one, plans were from an old Audio Magazine. With the other 2 15" powered subs, I get my bass fix. Very smooth system, always been fun to listen to, and I listen a bunch.
srs2: I have my SRS2's in rear against three sound panels which hang from ceiling and "form a wall" (wall of sound, huh?).
There are two different answers now for R to R - L to L or R to L L to R, which is right in a surround 5:1 situation? hmmmmmm. Time to vote! Like I said, I have them R to R and L to L -
I only see one answer, R to R and L to L as you have them.
You really have no idea how good those speakers can sound until you do the standard upgrades. Start with the replacement RD0194-1 tweeters from Polk. Then upgrade the crossover caps, resistors and consider doing the inductors. The electrolytic caps are way beyond their lifespan not to mention film/foil caps are vastly superior to start with. Once you pick your jaw up off the floor, there are still other tweaks to do.

The SRSs could not have been used with Mono-Blocks, unless the negative terminals were tied together. Not an expert on Mono-Blocks, but doesn't sound right. The SRS2s, if they're 4th generation, pin/blade, can be used with Mono-Blocks, providing an AI-1 interconnect was used.Home Theater/2 Channel:

Mono blocks could of been used IF the owner didn't connect the IC cable and of course no sda effect and only 1/2 a speaker.
-
I don't know, I thought he said mono blocks 1000W. I drove all night to pick them up at 5am, was trying to beat out a big spring snow storm. We did not talk very long. They were never clipped is what I was saying. I have Crown K1's which works out at 550W at 4 ohm, works great, never a problem.

Ah, the rabbit hole beckons!
Again, @F1nut, is spot on.
With the help of others, I've pretty fully mod'd two sets of SDAs, and like others on the Forum, I'll testify that you cannot believe the difference in sound quality made by bringing vintage Polks into the 21st century.
There's a set of "manufacturer refurbished" crossovers on eBay that should work with your SDA SRSs and allow you to upgrade your tweeters to the RD0-194-1s available from Polk:

Because I used these crossovers for a couple of years , I can assure you that they -- along with the tweeter upgrade -- make a huge difference. I was bitten by the upgrade bug and decided to TL my SRSs. Otherwise, these crossovers and RD0-194-1s produced excellent sound.
You might want to contact Trey [@VR3] about them.

Where can I best find the necessary steps and $$ amounts to join the rabbit hole, does somebody also have a list on these? Parts lists and instructions, helpful folks who will not rest until I work hard, spend my retirement, and forget the pool? You guys all help so much, maybe your experience can push my nose in the correct direction.
My system sounds pretty fantastic as is, better is always better. Push me. -
Phil, those are not exactly drop in as the SDA drivers would have to be changed from MW6503's to MW6511's.Political Correctness'.........defined

Those crossovers are for 1.2s. The OP has the original 2nd/3rd generation SRSs.Moose68Bash wrote: »I only see one answer, R to R and L to L as you have them.

They are not compatible.

Shouldn't the L/R SDA's be setup like this in the rear position? (But still hookup the rear left terminal to the rear left position and rear right terminal to the rear right position, like you normally would).
L .. C .. R
.............
R ........ L
That way the dimensional drivers of the SDAs stay on the same sides of the speakers (relative to the fronts).
If you did it like the folllowing, the dimensional drivers on the rears would be opposite of the orientation of the fronts.

Ya know, I think you're right. The dimensional drivers should always be on the outside, but I've never used SDA's as rear speakers. How are the SRT's set up?
Phil, almost seems to have been a good bet....LOL

Is how i run my sda srs and 1b's -
Does anyone have a firm answer?

I think the easiest way to think of it is you're hooking up the speaker wires to all the speakers like you would any normal set of 5.1 speakers. The only difference is you're swapping the physical position of the L/R SDAs in the rear, to keep the dimensional drivers in the correct position. So it looks like this (speaker-wise), but cables connect normally:

You are "probably" right!
I will try it and switch them and report back here when I do...maybe over the weekend.
Thank you for all the suggestions...
