SDA 2 Interconnect Cable Need to Make One

edited January 2012 in Vintage Speakers
I just picked a pair of SDA 2's with the Pin Blade Interconnect cable missing.

I live near Parts Express in Dayton, OH.

Would someone please give me a correct parts list so that I can construct a quality Interconnect Cable.

Is there a forum member that sells complete cables?

I am assuming it is no longer possible to buy an original one.


I can then audition SDA 2's vs. my Rt3000p.


Thanks,

Greg

    For a pin blade type the pin is the only connector that matters. The center pin or positive connector of a rca plug is the right size. I removed the outer ground of a rca plug and soldered that to the wire. Works great. Make sure the amp you use is common ground. You will like the sdas with all the drivers firing.

    Hi Indy, and Welcome to CP!:biggrin:

    You may be able to find an original cable on ebay. If not, they are easy to make.

    All you need to do is use a single, good quality RCA cable of an appropriate length, and remove the "petals" from around the center pins so that the pins will go in deep enough into the back of the speakers. That's it. The "blade" on the pin/blade cable doesn't carry a signal; it's just there for stability.

    If you would like a higher quality cable, made to order in terms of length, color, etc., contact pepster (Paul). He does excellent work, and has proven himself to be ultra-reliable.

    Congrats on the new speakers!

    Just curious about the Serial Numbers on your SDA 2's and if you have pics. Some models connected with the pin only, and some had both the pin and blade in use.

    E-bay is a good place to look for an original. I saw one go on there just last week. There may be someone on here that has one since a lot of the guys convert to binding posts. I would be very careful with the RCA cable deal (even though it works very easily) as the internal conductor on an RCA cable is normally very small. Since this interconnect carries full current speaker signal, a very small gauge conductor in the signal path can easily cause unwanted effects. If you can use a soldering iron well, it is very easy to make your own cable for this purpose, or as some of the others here have mentioned, there are guys here that can make one for you. Good luck and enjoy.

    No, I meant the part about SDA2's being blade/blade.

    There were SDA-2's, SDA-2A's, SDA-2B's, and SDA SRS-2's. Of those, some were b/b, some were p/b. The OP says his are p/b.


    edit:

    but the more recent OP, Indy, has not said which he has. Maybe his are b/b. That would be good to know....:wink:

    yea, but in my experience, when someone says "SDA2's", they could mean 2's, A's, B's, or SRS's.

    Thanks F1! And appreciate your assistance on the CarverAudio site with my Sunfires. They are dialed in and sounding great!

    I did pick these SDA2 up tonight. After stretching the side panels, re gluing fabric, and reattaching with a detailing, they look great. Got in some moderate listening without the cable, but with Sonic Holography on my Carver C9 and I'm enjoying the sound.

    Cables need to be blade blade for these 2Bs...any advice on making them is appreciated. I read some threads on the site for pin blade and was ready to go but need the blade blade, thanks

    You can buy the terminals and make your own, http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_248760_-1

    or you can buy one pre-made from Polk.

    To make your own, use a 2 wire cable of your choice. Run one wire from the large blade to large blade and one to the smaller blades.

    Here's a few pics of them. Pardon the bungie cord on one....glue still drying on top of the sides. No cord connected, so they are toed in for now. Pic of the rear indicates blade blade and is there only one such cord or terminal size for these? Brgman, will your cable fit mine?

    For you guys that use Carvers Sonic Holography, how does it compare to the use of the Polk interconnect cable? I didn't get much listening time last night, but they sounded very nice without the cable, toed in, and running through my C9 Holography generator.

    Would love to hear your opinions here, thanks guys.

    Got it, toe in now with Holography, no toe with cable - excellent. They will take the spot of my Norman Model 9s right behind them.

    Guys, before my "new" cable arrives (thanks in advance Brgman!), I would like to try out the effect. Can I use speaker wire and carefully place the leads in the slots? Large to large, small to small? Safe to try this? Thanks much.

    Use toothpicks to wedge the ends in snug and make sure nothing or no one can tug them out while juice is flowing.:wink:

    Thanks man, have them running now with smaller gauge speaker cord. Mikey Likes!

    But they are sitting out in the room in front of everything. Getting them set up without toe in will be a challenge in my room. They will go in the spots of the speakers directly behind them in the photos. So if I can't get them configured without toe in, they may have to be used with toe in, no cable and benefitting from Carver Sonic Holography instead of the cable effect. I'm assuming this means the outer Dimensional bass drivers may not be running full juice all of the time like the inner Stereo driver?

    I did notice that the inside ones seem to operate more than the outside and with some decent SPLs, they bottomed out with some Bela Fleck and Victor Wooten bass tones. Amp had PLENTY of reserve left, so no clipping going on. Meters in the lower quadrant on the McIntosh MC 2105 rated at 105 RMS.

    And one last question - odd load with these speakers being 6 ohms. My McIntosh amp has the old fashioned terminal strips with outputs for 4, 8, or 16 ohm, you gotta choose one. I am running them on 4 ohm, is this best or should I choose 8?

    Thanks Polk gurus...back to room with a cold one to enjoy some SDA effect!
