What are these rings?
Congrats on the new speakers!afterburnt wrote: »They didn't speak a word of English, they were from South Carolina.

Rings are a custom project that a member did a while back to create a better mounting system for the drivers. The steel ring is installed behind each driver, then the driver is mounted into its location using machine screws to sandwich the driver to the baffle, instead on wood screws into the baffle itself. A similar result can be achieved with T-nuts, but you don't have the support of tying all the fasteners together.

Here is the impressive internal bracing of my 1986 SRS 2. I was not expecting this based on the other vintage Polk speakers I've owned, but it is a good design that doesn't leave me wanting for much.

Hey Jake,
I am happy for you and am sure you are and will enjoy them. After reading the posts in this thread I am thinking about bring my SRS 2's to R.I. from NJ. They are the same as yours except I have already completed many upgrades.
Keep posting picture and sharing your listening experiences.
Enjoy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -
Nice SDA's and welcome back.
-
Congrats Jake! Glad to see you have some SDAs back into your rig! Plenty of mods that will help you tweak up the performance of those as you have already noted. Good luck and good listening!!Carl

Slow as a turtle, but I finished the Dynamat Xtreme on the second PR. Still have to do the eight mid-woofers, and still might use No-Rez or something similar behind the mid-woofers; even with the cabinet bracing.
-
Finished Dynamating the right speakers, so the mid woofers on the left unit are next.
Upper cabinet includes a third horizontal brace and a third lateral brace along the back connecting the top, back, and third horizontal brace. Can anyone convince me I need No-Rez behind the rolled stuffing and between each brace section? -

I used Blackhole 5 in my 2.3TL's and it definately made a positive improvement in the midrange congestion in them. I think it is definately worth the money doing it. The RD0-194 tweeters are probably more important than Blackhole 5, but I would do absolutely every mod you can to them Jake. At the end, you will absolutely LOVE them.

I also did Blackhole 5. Though I've not tried No-Rez, I can say the BH 5 is totally worthwhile. The improvement HR describes is easy to hear. The important thing is not to put too much in, just 3-4" wide strips behind the MS's on the back panel fro the top of the cabinet to the bottom of the lowest MW (no lower)."Science is suppose to explain observations not dismiss them as impossible" - Norm on AA; 2.3TL's w/sonicaps/mills/jantzen inductors, Gimpod's boards, Lg Solen SDA inductors, RD-0198's, MW's dynamatted, Armaflex speaker gaskets, H-nuts, brass spikes, Cardas CCGR BP's, upgraded IC Cable, Black Hole Damping Sheet strips, interior of cabinets sealed with Loctite Power Grab, AI-1 interface with 1000VA A-L transformer -

Just curious, what are the primary differences between the SRS 2 when compared to the 1C. They look quite similar in driver configuration, except the two tweeters are between the drivers in the SRS 2's rather than above them like in the 1C's.Good music, a good source, and good power can make SDA's sing. Tubes make them dance.
-
The SRS 2s are half of an SRS, so they have a 15" PR, tweeters between the midwoofers, and larger cabinet. The 1C has a 12" PR, and reworked driver layout with tweeters above the midwoofers; they can work better in a smaller room. The SRS 2s have deeper bass and a larger sound stage, but do like more power and more room; they are also harder to drive at a single-amp, 4ohm load. Even though both are very popular, the SRS 2s are among the most rare SDAs, and I was excited to join that elite fraternity.
-
Gotcha, thanks.Good music, a good source, and good power can make SDA's sing. Tubes make them dance.
-
I actually wanted a pair of SRS 2s over the big boys because they seemed like the best combination of size, sound quality, power requirements, and room friendliness; plus I later found that the build quality of my 1986 version are second to none of vintage Polks.

Jake, I have not touched my SRS 2's since I bought them, and don't listen to them that often because reconfiguring the whole audio system is a major pain. Would you mind a visitor for a couple hours after you complete your work?

My mistake, your forum name is very similar to a guy on AVSForum."....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963) -
After the encouragement to use NoRez/BlackHole on my SRS 2s, I started to do a little research, and read a white paper that Danny Richie did on the design of NoRez. To him, the most important aspect of the product is the deadening layer to reduce panel resonance, and the foam top layer is an added bonus to help with reflections and a little HF control. With this in mind, I started researching similar products, and found that GTMat (making of many automotive deadening products) makes a product called Quadro; deadener -> foil -> deadener -> foam. I contacted GTMat about the Quadro, and the rep said it could be used in the cabinet of a speaker like we would use the other two products. The Quadro is priced at $13 a sq/ft, so much cheaper than the other two, but not a purpose designed product like the other two, I wasn't convinced it was up to the same level. However, the nice rep was very convincing with two sq/ft of sample Quadro, enough to outfit both my speakers.
I'll post pictures as I install the the mat, as the SRS 2s cabinets are braced horizontally and vertically, and I'll have to cut 6 sq/in squares to place behind each driver. The Quardo arrived tonight in the mail and it is both thicker and heavier than I expected. In theory the Quadro mat should perform very well, especially with the factory batting installed between it and the drivers, and I'm very interested to give it a go.

Definately interested in your findings Jake. How does it attach to what you are applying it to (in this case your speaker cabinets)?

Quadro may work great, but not so sure the cabinets need resonance control as much as preventing the back wave of the MW's from coming off the back wall, returning to the cone and interfering with excursion. When that happens it prevents the cones from moving as they should causing a slight congestion or lack of clarity in the sound.
The polyfill Polk used is supposed to prevent this, but after installing the BH 5 I found that it needs help."Science is suppose to explain observations not dismiss them as impossible" - Norm on AA; 2.3TL's w/sonicaps/mills/jantzen inductors, Gimpod's boards, Lg Solen SDA inductors, RD-0198's, MW's dynamatted, Armaflex speaker gaskets, H-nuts, brass spikes, Cardas CCGR BP's, upgraded IC Cable, Black Hole Damping Sheet strips, interior of cabinets sealed with Loctite Power Grab, AI-1 interface with 1000VA A-L transformer -
It has a pressure sensitive adhesive, and I was assured it would work on clean wood.
-
I had a pair of Monitor 5 Jr+ a few years ago where I installed foam on all the interior cabinet walls, and I was amazed by how much cleaner the sound became. That application was probably overkill, but it was a great proof of concept for me!
-
I've also decided to upgrade the blade-blade SDA cable to 2-pole SpeakOn. It's easy to do, can only help, and why not if I'm upgrading everything else on what should be my last pair of speakers. I'll probably do it when I do the crossovers, but it'll be toward the bottom of my list. My Dodd equipment already uses SpeakOn connectors, so why not add them to my speakers as well!
