Hawkeye's SRS2 Experience

My next question is this:
I'm about ready to install DK's Dreadnaught. I have new binding posts for the change. Can I just add a jumper from the pin to the new post and keep the orignal wiring intact?
I'm thinking that if I can, then the original SDA wire could be used in the future without going into the box and moving/removing anything.
GordonHow does this sound for a xover upgrade:
ClarityCaps ESA for the 20 & 40
ClarityCaps MR for the 12 & 4.4
Dueland Resisters
Reading here and other spots would seem to support this combination. Parts would be about 1K, plus labor.
Would this combination result in a very clear and articulate mid range? The RDO-194's are on the way so I'm thinking a step ahead. I have to have a very clean and defined mid range since I listen to a lot of jazz, big band and some classical (wife).
Feel free to poke holes or make suggestions. I'm budgeting 1k for parts so please keep that in mind.

I was considering replacing the top and bottom plates with piano black acrylic and replacing the vertical wood strip with a strip of matte aluminum to mimic the rest of McIntosh gear.
Gordon
I am also looking at the piano black look. Aluminium would be a nice touch to match the McIntosh gear. I will try with a 30 mm aluminium inlay in the wood strip. I believe all in metal could be too much. The 1.2TL's are tall so would not be too much black paint visible if they were all in metal. Been to the boys toy store today and bought myself a router and some wood to experiment with.HT/2 CH

Be VERY careful with a router as they are nothing to "play" with ! I also suggest that you wear hearing protectors when routing, you'll thank yourself and your ears/hearing will thank you also !;)

Have I gone off the deep end?:eek: After speaking to a couple guys here I placed an order for my xover upgrades. So it is documented for others here is what I've ordered:
4 RDO-194 tweeters @ $203.52
2 .5 Ohm Duelund Resistors
2 2.7 Ohm Duelund Resistors
4 7.5 Ohm Duelund Resistors
Cost for resistors: $134.64
4 ClarityCaps ESA10
2 " " ESA18
2 " " ESA12
4 " " MR2.2
2 " " MR12
Cost for Caps:$858.00
I did come in $8 under budget for the xovers:D So I'm into these things about $1600 including Dynamat, tweeters, Dreadnaught, Rings, Caps and resistors and all the bits and pieces I've bought. After the outsides are finished, I think I'll top out at $2k. I know I'll never recoup that if I ever sell them, but I have a feeling this is going to be sweet pair of sounding speakers for 2K!

I'm getting ready to spike, dynamat, ring and Mortite my 1C's very shortly. I'd like to get it all done at once. Also thought about replacing the high pass Sonicaps already in place with Auricaps, but I'm not convinced they will be better.

H9, I initally was going to do the whole shooting match all at once but I wouldn't have learned anything along the way. Your much more versed in this stuff than I am so I would imagine you'd have a better ear than I. I've enjoyed taking my time and seeing what each little change has done. What little I have done so far has, in my mind made a big difference.
I'm just hoping the xover upgrade is going to have the desired effect. Perhaps a bit of buyers remorse on my part?!

I wouldn't bother, the difference would be minimal, if any at all.
eh,, mundorfs maybe.
ya'll know that sonicap has a sale on right now? FWIW--I replace all the caps in my 1C's with sonicaps and it was very reasonabe. YMMV.JC approves....he told me so. (F-1 nut) -
Well, I finally have all the drivers covered in Dynamat Extreme. The last four I did were the dimensionals. I have been doing them in stages to gage the improvement. Now that the dimensionals are done, the mids and bass have seemed to blossom with a greater width, depth, tautness and richness which I thought was missing from the stock speaker. As others have mentioned, this has been a very beneficial tweak.
I also tried and quit using the Mortite on two of the drivers. I laid out a single thread and overlayed it with wax paper and rolled it out very flat and thin. I still managed to strip out three of the eight screws. No wonder Larry developed the rings! I don't see how this was done without destroying hundreds of screw holes. I have not ruled the Mortite out just yet, I have to see what it sounds like with the rings installed and the stripping is eliminated.
Still waiting on the RDO-194's to arrive (I need them bad). Hopefully, they should arrive Friday. Quite a few of my xover pieces are on backorder, but I'm not ready for them just yet anyway.

Gordo, if the original gaskets are intact and good condition they work just fine but instead of Mortite I would suggest buy Part Express Speaker sealer. You won't be stripping out any screws and it seals very well and is very easy to work with and you don't have to flatten it out with wax paper, you just use your fingers to push down on it when applying and it gets as thin as you wish.

I've used it on my PRs and Mids (where the gasket was shot) and I fixed a 2' split in the lower right hand corner seam of my 1.2TL with this stuff. It really is great and cheap and easy to apply and remove. -

I've used Mortite with no issues and it sounds great. Sorry you had trouble with it.

I just did the mortite to my SDA 2A's yesterday. Fortunately I had purchased the rings from Larry, so I was able to tighten everything down with no problem. Have not cranked up the system yet, but hope to get everything put together tomorrow and check out my mods and tweaks on these speakers.Sunfire Theater Grand IV

I've been very slow to do mods and post my impressions But, today changed all that, at least for today. I replaced the 2k tweets with the 194's earlier this evening. The gaskets on the 2k's were in excellent condition and reused them.
I'm not prepared to do an indepth call on these tweets just yet but, this is without a doubt, a huge improvement! I've only a couple cd's played and the difference is night and day. I know this term gets thrown about with a lot of tweaks so I only use when it is true to me.
Thanks to everybody who has recommended this upgrade. Well worth the money so far.

I'll no longer doubt you Jesse! These tweets are very smooth, dare I say, silky and articulate without any harshness or sibilance I heard with the 2k's

I have just read this entire thread, and I have a pair of Polk SDA SRS 2 speakers in storage. You guys give me the urge to do these mods and not just resurrect, but improve on these speakers. From what I gather there is no upgrade of the other drivers involved here- just the tweeters.
There are some pretty nice speakers out there for what this is going to cost (~$2K.) Not to mention the biggie- the SRS 2s never had any WAF at my house! I don't really have a good place to put them, but I am planning to build out "sort of" a theater in the basement exercise room. The new old Polks could be the R&L mains. -

Welcome to Club Polk kjgarrison. Don't know how you came up with the $2k figure but to replace the the tweeters with RD0194s and update the crossovers with Sonicaps & Mills resistors and upgrade the binding posts shouldn't cost you much more than $500 and then you will have an incredible sounding speaker. Oh yeah, I forgot you want to Dynamat the MW driver baskets which should only cost you about $20.
Good luck and let us know what you decide to do.
BTW if you do decide to upgrade the tweeters call Polk Customer service and tell them you are a member of this forum. You will get a discount on the RD0194s plus free 2 day shipping depending on where you live. -
I'm sure you can update these speakers for much less than 2K. I took 2K as a limit to me, but mine need exterior work also. Along with that, I had to buy an AI-1to use while I built a Dreadnaught. My crossover upgrades have different parts than some other folks use for an added (maybe unnecessary) cost.
The four 194 tweeters ran me $203 shipped which was a great improvement over the 2K's.
Taking inflation into account, these $2500 speakers in 87 would cost about $4800 today. With a 2K upgrade, $6800 speakers fit nicely with my gear.

Thanks hearingimpared. I need to some searches in the forum and look up quite a few of the concepts, products, abbreviations, and terms used in this thread before I can speak the language with you all- even in a rudimentary way. I also need to evaluate my own SRS2s to see what they need. I know I have a few crumpled dust caps among other issues which are different from the OP's. Then also I wonder if upgrading to SRS1s would be worth it.

Thank you, Gordon. I think I'm perhaps more of a DIY'er than you, particularly with regards to xo building and soldering where I have some experience. Plus, my speakers undoubtedly have different issues than yours. I'll be interested in following your progress and have subscribed to your thread. It is like a free gift to learn from the accomplishments, and mistakes, of others.
I'll be starting my own thread so as not to hijack yours any more than I already have. Good luck. -
Welcome kjg! You're right, I don't know my way around a soldering iron or cap. Thanks to several guys here, they've pointed me in the right direction and offered help in rebuilding the crossovers thus allowing me to keep all ten of my fingers!
I look forward to reading your thread and learning from it also. Feel free to put your opinions and recommendations down here also.

I finally listened to Pink Floyd DSM SACD tonight on the SRS2. I've been holding off until I had a feel for these speakers. I decided to take an evening off work, opened a bottle of adult beverage and warmed everything up since my gear likes about 40 minutes before it gives up the best sound.
I was disappointed. While the highs and lows were fairly accurate, the mids were very smeared and congested. Most notably during the complex passages of Us and Them. It sounded like a high school garage band playing This was pretty surprising since most music I've listened to was nicely presented.
I'm hoping the crossover upgrades I've planned will clean this up to a large extent. Even my wife mentioned it sounds terrible, and everything usually sounds good to her!

I've never thought DSM was all that well recorded. Many use it as a demo and I never got why. I haven't heard the SACD version. But I have 3 redbook releases and when I'm in demo mood or just want to hear a well recorded and presented musical piece I never grab PF-DSM. I love it for the music, but not necessarily the recording.
YMMV

It was thought of as being well recorded because of all the back and forth from left to right with the coins and all the clocks, but every copy of this I have heard sounds ok at best from a quailty standpoint. The 5.1 SACD copy makes for a more entertaining recording, but I to must agree that it is not a good choice for critical listening or auditioning a system.
