SDA Binding Post Cups ?

I bought a Fully Assembled 800VA Dreadnaught in one of Larry's cases (Very nice cases, he
should autograph then :cool:) from nspindel so I need to redo the binding post cups for my 1C's,
remove the RCA connector I was using for the SDA cable and replace it with 2 posts. Now
seeing how I still have to do the binding posts for my 4.1TL project I decided to design a new
cup out of "Derlin" that can be used on both the 1C's and 4.1TL's, I got a quote for my design
and just about had a heart attack, The wanted over $700.00 for 4 cups and 29 days to make them
I don't think so!
Next step was to see how much it would cost to have 4 3 1/2" Dia x 1/4" thick plates with 5/16"
holes for the posts made like the following pictures.
2 of these for the 1C's
2 of these for the 4.1TL's
At $140.00 and 17 days again I don't think so! That's $35.00 a disk!!
Keep in mind that a 12" x 12" x 1/4" plate of "Derlin" cost about $25. Maybe I'm just being a
cheap SOB, I don't think so. What do you guys think.
BTW: I don't the tools needed to cleanly cut out the disks without leaving a hole in the center
like you would using a hole saw.

I could probably get aluminum plates made for the SDA approximately $25.00 per plate if I could get a large enough commitment from you guys- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

Would they be machined for the Neutrik speakON 2-pole connector for the SDA cable?Family Room, Innuos Statement streamer (Roon Core) with Morrow Audio USB cable to McIntosh MC 2700 pre with DC2 Digital Audio Module; AQ Sky XLRs to CAT 600.2 dualmono amp, Morrow Elite Speaker Cables to NOLA Baby Grand Reference Gold 3 speakers.

Tony, eff all that just replace the stock IC socket with a Neutrik socket and terminate the cable with the matching connector. If you don't want to do it yourself, send them to me.Political Correctness'.........defined

Trey,
Although this great guy in "NC" just finished redoing my stock binding post cups on the SDA SRSs and probably has already done the binding post cups on my 1Cs (), I would probably plump for the aluminum "upgraded" cups for both sets of speakers - ah, vanitas vanitatum!
Would they look like the ones Toolfan66 designed for his speakers?Family Room, Innuos Statement streamer (Roon Core) with Morrow Audio USB cable to McIntosh MC 2700 pre with DC2 Digital Audio Module; AQ Sky XLRs to CAT 600.2 dualmono amp, Morrow Elite Speaker Cables to NOLA Baby Grand Reference Gold 3 speakers.

It would be round, a drop in replacement to the stock SDA cup. No woodwork modification needed.
I have thrown out the idea before -
It would say "Polk Audio" in the classic font, +/-/SDA
Brushed aluminum
If I could have 10 pairs spoken for, I would do it for $25.00 each but I do not plan to "stock" these like my Fortress plates...
If we can get 10 pairs sold, I can get the ball rolling and have a "product" in 3 weeks!- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
I'd be in for a set for a pair of 4.1TL's.

Trey,
Consider two pairs spoken for!Family Room, Innuos Statement streamer (Roon Core) with Morrow Audio USB cable to McIntosh MC 2700 pre with DC2 Digital Audio Module; AQ Sky XLRs to CAT 600.2 dualmono amp, Morrow Elite Speaker Cables to NOLA Baby Grand Reference Gold 3 speakers.

We are getting there! :-D- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

Also, this would be completely compatible with inductor mounted terminal cups - you would mount the plate with bolts, fasten it from the inside then thread the old terminal cup through on the inside, run the wires through, then bolt the old terminal cup down on the inside!
It makes sense in my mind atleast!- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

Not to put a damper on what Trey is offering but I think what Trey is talking about is a round flat 1/8" thick brushed aluminum plate with all the holes pre-driled, that would mean all the binding posts and the Neutrik NL2 connector out bast the back of the speaker, so if you ever have to transport the speakers on there backs which SDA's should be you'll have to remove that plate first.
This is what I had in mind but at around $170.00 each I don't think so.

No damper, sometimes we just have to be realistic! (That design would be nice, but wowzers) :-P A lot of modern day speakers utilize a plate with post sticking out... definitely would not have to remove it when in transit.- Not Tom ::::::: Any system can play Diana Krall.

I don't like the cup look. Nor do I like its function getting at the binding posts. This is why I made mine flat.

Eh, I like the cup.A lot of modern day speakers utilize a plate with post sticking out... definitely would not have to remove it when in transit.
Sure you would if transporting them on their backs otherwise some sort of provision to support the speaker so they don't rest on the binding post would be required. Even with the cups aftermarket posts stick out and the above cautions should be taken if placed on their backs.Political Correctness'.........defined

I like the cup as well, but not enough to spend $170.00 for them. I would definately prefer a cup to a flat piece though.
Taken from a recent Audioholics reply regarding "Club Polk" and Polk speakers:
"I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion."
My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

I will ask the CNC shop to price out a cup design for you knuckleheads! O_O- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

It's expensive to machine a part like this. Another thing change that angle going into the cup to just being 90 degree going in. That alone makes it easier to machine.
Also you need to ask yourself what am I gaining by having a machined cup to what is already there? My purpose was to have more room between the binding posts. But not everyone wants to or has the know how to cut into their speakers the way I did mine..

To me $25-30 dollar to have a plate outfitted with the appropriate room for the NL2 and bi-wire binding post makes sense...
Anything over the $40.00 mark would seem a little crazy to me...- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
I would honestly just rather have 1 set of binding posts and NL2 and thats it. No bi-wire.
-
Hey Andre!
What I may do, will talk to the CNC shop is like Tony did - have a point on the back that would allow someone (me probably, haha) to drill additional holes to accomodate different configurations (The point is so that it is straight)- Not Tom ::::::: Any system can play Diana Krall.

I hope you'll be sitting down when they give the quote.:eek:It's expensive to machine a part like this. Another thing change that angle going into the cup to just being 90 degree going in. That alone makes it easier to machine.
I did it both ways and the price wasn't that much different. Go figure I guess most of the cost is in the set-up.Also you need to ask yourself what am I gaining by having a machined cup to what is already there? My purpose was to have more room between the binding posts. But not everyone wants to or has the know how to cut into their speakers the way I did mine..

I just wanted a drop in replacement cup with a deeper cup so the post wouldn't stick out past the back of the speaker. Access isn't an issue as I use Banana Plugs and I really didn't think it would run that much.To me $25-30 dollar to have a plate outfitted with the appropriate room for the NL2 and bi-wire binding post makes sense...
Anything over the $40.00 mark would seem a little crazy to me...
I agree, I can almost see $40 for a beefy cup setup the way I wanted it but then again it's just too much money, You can get the NL2 connectors and stick them in the stock cups for a set of speakers for a lot less then the cost of one cup.“The two most important days in your life are the day you are born and the day you find out why.” ~ Mark Twain
