Original owner looking for help

ltleo74

Hi. I'm new to this forum. I'm hoping to be an active member and could use all the help I can get with regards to my Original SDA SRS.

My father purchase these new in 1987. I still have the original manual and actual purchase sheet via vendor and price.

I have kept these speakers always inside and they have always worked. I have not actively used these speakers in about 13 years, but they have stays in my living room. I have a few other audiophile setups but I really want to refurbish and/or bring back to new form. I also still have the original Mcintosh 2500 amp that was paired with these.

I contacted Polk and they were great suggesting i look via,the forums and also can purchase all the new drivers and tweeters. Now these speakers work, well did 13 years ago. I'm looking for really a vendor who can bring them back to new or even change out the cones to,the newer models. I can do,it myself with guidance,,but don't mind paying a professional or craftsman that can do a better job then I can. They hold a lot of value to me due to belonging to my father whom passed, as well as being the cause of me becoming an audiophile today.

I kindly ask for any help and or guidance. IM located in NJ.

Thank you and I look forward n becoming fronds with all.

Welcome to the Forum. You've inherited a great set of speakers that can be brought into the 21st century with modifications many (including myself) have done or had done to them. Many threads on this Forum give accounts of what others have done, and there are guys on the Forum (e.g., @westmassguy) who can do the work for you, if you prefer. I had two sets of SDAs modified by Vr3 Mods, but the owner of that shop (Trey) has since moved on to other things.

There is no limit to what you can do -- well, there is a limit, but I wouldn't test it.

Oh, by the way, hold on to your wallet. Mods that are possible are both worthwhile and sometimes costly.

Thank you very much. Please excuse my novice approach on how,or where to start.

I'm torn between, replacing all original and bringing back to factory specs, as I've enjoyed these speakers for many years growing up. Or do I modify them. Will that ruin the over all aspect of what these speakers where/are?

I have other set ups that include Wilson Sophia and totem wind designs. So these can I bring them to live music?

I apologize about my lack of direction. I'm as i stated torn between do I change what is an original owner set in good condition to something else and if,so.... Where to go?

Thank you again

Gently and evenly press in on each 6.5" midwoofer. Are any of them frozen or do they make scratching noises as they move?

There is absolutely no reason to replace the mid-drivers as long as they are working. The tweeters on the other hand should be replaced with the RD0194-1available from Polk as they are considerably better than the SL2000.

Other than that, upgrade the crossovers, add spikes, add Dynamat Xtreme to the baskets, install Blackhole 5, install Larry's rings or Hurricane nuts, upgrade the binding posts and the jumpers.

Hello Len and welcome to the forum. I have a pair of SRS's that have been modified by westmassguy and me and have no regrets. Mods include RD0194 tweeters (no need to preplace MW's if not frozen), glued M/W magnets, resealed inside seams, tightened loose end caps, and some I can't recall right now

Some mods with pictures:

Binding posts (DIY cables and jumpers from Doug- douglasconnection)


PM if you would like to discuss.

Thank you all very much. I'm further N. Jersey, around exit 152 PKWY.
With testing the cones via gentle push, I think I found maybe one on each speaker with some crackling noise. Other then that, I get crackling via the passive large plate on the bottom when I push the shield.

I would rather replace each cone/tweet either with factory or upgraded, just to refresh it all.

My biggest fear is I'm not sure if I can or should actually try to do this myself or attempt to find a qualified tech.

Replacing speakers I'm sure I can do as it's just screws plug and play (I believe) the cross over is where I tend to be cautious.

Also, what were or are the main factors of those whom replaced with driver choices?

Welcome to the room. You are at the right place for modifications as this place
has some very smart people when it comes to Polk speakers and anything audio related.

Congrats on the inheritance..

There's no reason to replace the midwoofers, or "cones" as you put it, if they're working. Only the tweeters.
