Is there any speaker out there that can do what an SDA does???

Ken can not fix this.. and I think he knows it.... the drivers are made in china to a certain spec.. problem is it's not great, or right. not much the guy can do...

I have zero doubt that Ken CAN fix this, but you would have to check your arrogance at the door. I have little hope that you will do that, as your problems could have stopped years ago if you had used 100th of 1% of the advice and suggestions you have received here in that time.

I sincerely wish you the best of luck in continuing to be the smartest member of CP, because it is working out so well for you...

Welcome to my ignore list.

Hello bobt,
Either the rear suspension, called the spyder, has had a glue bond failure or become torn. As long as the voice coil former has not been severely damaged Freeman stands a good chance of repairing it and making sure it meets all specifications. He can measure distortion, power handling, insuring that all T/S parameters are correct.
Believe me nobody can test and build a speaker component like him. If for some reason he can't make the driver work perfectly he might be able to build one up from scratch.
Regards, Ken

^ This is the reason I will stick with Polk. Boutique speaker manufacturers aside you won't find customer service like this, and Ken specifically, from your average speaker company.

@bobt Second chance, you'd have to be crazy not to take Ken up here.

Ken... Really??? you know as well as I do the replacement drivers for the MW6511 is well... half ****, what I got 15 years ago worked perfect.
Now if you really want me to send you the new stuff I got... ok
I have the original 1987 driver, but I think the coil is screwed. NOBODY will fix it. I have tried....

Really you know what i'm talking about here,,,,
If you really want me to send it to you I can do that.. you know what i'm talking about..unless the speaker works 100% then not worth the money...

The other question is what is this going to cost me???

[Deleted User]

There would be no charge, except shipping to Polk.

Yaknow, the more I read the complaints, the more I'm leaning towards wired backwards and pushed silly. Just a guess.

They may also be wired incorrectly. On the 1Cs, the 6511s are wired in series, while the 6510s are wired in parallel. If the 6511s are wired in parallel as well, that could be part of the problem.
I've ordered several replacement drivers over the past few years, and have not had a single one fail, or pop when driven hard.

Your social skills are.... not good.

Ken, I would love to send you the driver.. but really you asked the same thing 2 years ago if not more. You sent me a number of drivers.. they did not work.
These original speakers are from 1987... they have only needed 1 driver replacement back at least 13 years ago. That driver works 100%

The New China drivers.. just do NOT work. Really? you think these new drivers are what they should be??? I have put them in the other speaker... it's not the speaker it's the driver... it fails all the time. These speakers POP... all of them do the same dam thing..... The original speakers work..100%

Now really if you don't know this.. you have to be kidding me...
IF you could make real drivers that worked.. then the speakers are worth while, but I have tried this, and given you guys a few years to fix it... so far, nothing works.
I don't know what to tell you except if you really think this replacement driver is good.
then you need to get a grip....

Ken, I'd walk you through it, no worries

Ken I will be glad to send the driver back to you. Just give me the address and who I should send it to.
To be honest with you, if you have worked for Polk over 15 years... you should know the new drivers.. don't work that well... just saying. If you really think you can fix it, be my guest. I have tried to get the original Polk driver fixed. No speaker repair place will touch it....

ZLTFUL

Polk ships thousands of those drivers since the new driver was introduced...the VAST majority have no issues whatsoever.
Sometimes you have to stop and think...Huh...maybe *I* am my own biggest problem.

oldrocker

I thought they closed this thread way back...

Nope, we all need laughs, and well.... this has been providing me with some good ones....

Bob, almost all of your replies in this thread have said the same exact thing over and over. We all know how you feel about the bad driver. YOU are the one that needs to "get a grip" here.

A long time employee of Polk is offering to help you. Even mentioned he might get a replacement built from scratch. And yet though your bullheadedness arrogant know it all mentality. You still want to be difficult. If I were in your shoes I would be very glad that a manufacturer is trying to help you for merely the cost of shipping this bad driver to them!

With your attitude in this thread I am beginning to wonder if you even have a driver issue. And are just here to stir the pot and troll.

Ken S....you have amazing reserve and patience. I mean it seriously!

Hello bobt,
I worked for Polk's CS department for close to 15 year, some of it as manager. Now I'm considered a "contractor" minding the forum, but still maintain a friendship with the folks who work there. To quote a line from "Fury", best job I ever had. You would send the driver to: Polk Audio, 5601 Metro Drive, Baltimore, MD. 21215 attention: Kim Jasper. Please include a short note giving him your name, address and a daytime telephone number.
I'll let him know to expect it.
Thanks for sending it in.
Best regards, Ken

Great line! Got to see it in context to fully appreciate it. Thanks for your efforts Ken. You have more patience than I.

Maybe a little debugging trial and error is needed. Why not remove one of the drivers from the other speaker and place it in the location of the problem. Install the new driver in the location of the driver that you just removed. Then give it a listen and see if the problem/pop moves with the new driver or continues with the older driver in the original location of the problem. This would help determine if the problem is with the new driver or maybe, just maybe, it is a wiring problem which others have mentioned.

I've had a pair of SDA SRSs for 2 years, my dad had them since 1985. We never once had a problem with the drivers and sometimes played them to deafening levels as they were available to me when I was a teenager. Back then I may have had a heavy hand on the volume. And he had some pretty significant power running to them back then.

You should hang your head in shame for writing such a post.

@bobt Did you ever send it in? Curious what Kim Jaspers conclusion was.

headrott

I am curious as well. I bought a MW6511 (made in China replacement) about 5 years ago and put it into my 2B's and had popping problem with it. I have not used it for about 4 years and it is collecting dust. I would definately be interested in finding out about the results of sending in bobt's driver to see what happened.

***I know this may not be a popular stance here in this thread, but it is an honest one). The MW 65011 made popping sounds in my SDA 2B's (which were at the time not modded, and in original form (except for the replaced MW6511 of course). I also know there have been a few other complaints about the replacement MW drivers giving "popping" problems. ***

Any further information; I would be interested in the results. Thank you kindly.

I hate for this to be my very first post on the Polk Forum, but after sitting here for the past couple of hours reading this entire thread, I just had to say something...

For starters, I have to say that working in retail for quite a while now, one thing I hate more than anything else with people is arrogance. There's absolutely no need for it whatsoever and just comes off as being rude. Well actually, it IS rude. Period.

Okay, with that said, it seems that nearly ALL of bobt's posts pretty much say the same exact thing time and time again. Almost like every post of his is cut n' paste for the past 9 pages of this thread. Grammar, spelling, sentence structure (or the lack thereof), responses to very trying, helpful members is atrocious. Not to mention all of the questions asked that have still gone unanswered by bobt, even after four full months in this thread.

Early on in this thread as well as the "speaker cable" thread that bobt started five years ago (yeah, I read a bit of that one too), he stated that he has high-end equipment. Sorry to tell you this bobt, but you don't. The Adcom preamp is mid-fi consumer grade, the Integra amp is mid-fi consumer grade, the Jolida tube CD player is mid-fi consumer grade. Is it all junk? No. Is it high-end? No. However, that is all irrelevant. I just wanted to make it clear to you that the equipment you have is NOT high-end gear.

First off, the amp... It's old. It's needing a major re-cap among other things, especially if it's been constantly ragged on all of these years, which it has from what ole' bobt keeps telling us. Sure, it's a good amp, but the thing is probably running way out of spec, bias is probably way off, and it's probably not putting out nearly as much power as it once was. This means that the amp is running into clip mode a lot sooner than you think. Clipping and speakers do not get along very well.



Second, these replacement Polk drivers you keep getting and every one of them "popping"...

Are you even giving these drivers any kind of break-in period at all at low volumes or are you simply slapping them into the enclosures and blasting the heck out of them?

And the reason these "cheap junk China drivers" as you keep referring them as continue to pop when you remove them and put them in the other enclosure is because you already blew the poor thing. If you take a blown driver out of one speaker and transfer it to another speaker, it's still blown. It's still going to make horrible noise. That's like asking the question "If a tree falls in the forest and no one is around to hear it, does it actually make any noise?"... What do you think? Do bears **** in the woods? Yeah, same answer for both questions.

You know bobt, you keep calling everyone on this forum fools, telling them they don't know what they're talking about, telling them to get a grip, and overall just being completely condescending with everything you say to everyone that tried to help you, even Ken!

Seriously, are you that arrogant and have that much pride that you can't accept help from others when that help is given countless times from a bunch of willing members, and have that much pride that you can never ever admit that you just might be wrong or that your amplifier might be the root of the entire problem?


And lastly, the RTi 12's... I have a pair that I've been running for about the past six months and really have no major complaints about them. They replaced a pair of mint NHT 2.9's that just don't seem to work well in my room, so they are being stored at my brother's house for a while. Believe it or not, the RTi 12's sound an awful lot like the NHT's, and the 2.9's have also been accused of being "bright" just like the RTi 12's. With that said, they do tend to be tipped up a little bit, but I certainly won't call them bright by any means. Then again, that could also be the contribution of my gear upstream. I'm not going to list everything here as you can see it all in my signature below. What I can say though is that my receiver (which I'm using as a preamp only) is known to be a bit on the warm side, which is why I chose it. My amp I had custom built to my specs by Klaus and he did an excellent job as always. It's biased pretty hot into Class A, a lot more than typical because that's what I asked for. Anyway, it's also a bit on the warm side. Then you've got all of my interconnects and speaker cables, chosen for the same reasons.

That's not to say that my system lacks detail or is rolled off on the top end, because it isn't. It's just as airy and extended as anything, but it's not over the top and in your face. However, if there's a crappy recording, it's going to let you know about it as well. Mids and vocals are natural and open, and the bass is fantastic. The RTi 12's bass extends just as much as the NHT's, if not a little more, but also have a little more usable output down there as well. The best part about the bass though is the dynamics, detail and control, especially with the amp I have. The amp's damping factor puts a massive "clamp" on those six 7" drivers and never lets go. This is where the Polk's excel over the NHT's. Even though the 10" woofers in the NHT's are in a sealed enclosure, they just don't have the speed and control of the Polk's smaller, lighter, multiple drivers, and it's quite obvious. And I haven't even mentioned anything about the wide and deep sound stage or the imaging that these RTi 12's are capable of in my system. Very three dimensional. I'm sure they don't compare to the SDA line, but they certainly do a very good job nonetheless, extending well beyond the boundaries of the room.


Anyway, that's about it. It's a bit more than I had originally planned on saying, and it isn't what I originally had in mind for my first post on the Polk Forum, but there it is.

I'm sure I'll be told I don't know what I'm talking about and that I need to get a grip, and that I'm a fool, but that's to be expected. And no, I never mentioned what I do for a living or what my other hobbies are, because they have no bearing on the subject. Oh, not only am I a musician, but I also know plenty of musicians, most a LOT better than I, and I can tell you right now they don't know squat about stereo equipment and loudspeakers. Just because they are in the business of making music doesn't mean they know anything about the electronics that reproduces that music. In fact, I'm the only one out of all of them that has a somewhat decent system and knows or cares about stereo equipment. That goes for the guys/girls that I deal with in the IT field as well.

Anywho... Hello everyone else! Glad to be here!!!

Ken, did this ever go anywhere? I am about willing to bet Bobt never sent that driver to Polk.

Not that I am aware of.

Welcome to the forum. That said, I don't think there is a need to pile on the OP as other members already have.
Ken Swauger took the high road and provided a generous offer to resolve bobt's issues with his speaker. As I previously said, it's bobt's loss if he doesn't take advantage of the generous offer. Perhaps something else has intervened in his life and this is no longer the priority it once was. Let's hope all is well with him.

How sweet... Beevis is sending get-well wishes to Butthead.

I read of few of your other posts before I saw this one and I thought you were going to be a nice addition...and then I read this gem and it confirmed my suspicions.
