Hello. I'm Gordon. I fix speakers.

[GordonW]

Is that enough said? :scratch2:

Been here for nearly 4 years now... and I have to say, nobody else on the Web holds a candle to the variety and substance of the discussions here. This place is the s***, without a doubt.

Feel free to bug me about weird, arcane, unworldly speakers or speaker parts. I might have seen one of them. I've seen some strange stuff, over the last 23 years of working on and building stuff. Can't promise everything, but boy, the stuff that comes through here sometimes... :yikes: And besides, every new thing you guys send me, is something I'll know about the NEXT time somebody asks! :D :D :D

Regards,
Gordon.

Hey Gordon! I found a pair of midranges for the L-1090's, now they are whole again. I have to do some minor repair where the dayton's were, but they sound great. Oh yeah, if any of you are wondering about Gordon's knowledge and ability to repair speakers all I can say is that it's superb!

Gordon is "da man", always informative and helpful - and lots and lots of real-world, hands-on knowledge. Kind of kicks theory's butt once in a while. :smoke:

Glad to have you here, Gordon - Thanks for all you do!

Gordon always has insightful information on the most obscure speakers. But we want to know what you really think of Tannoy speakers. :D

Cheers, Gordon.

I'm still diggin' that cherry pair of EPI 100Vs you sent me.

[bigstereo]

He fixes speakers. Yes, and he does it very well too. I have the results of some of Gordons work in my system. :thmbsp: Thanks again bud.
I've learned a lot about speakers from reading Gordons posts here and elsewhere. He is one of my "audio heroes".

[simplynuts]

Okay here is one. Are you familiar with pilot speakers? The woofer has a tweeter mounted in front of it. Nice wood cabinets, but can't find any infoe on them. I deided to pass them on and left them curbside with a free sign on them. My son's friends picked them up tonight.

Eep. :yikes:

Those could have been really cool, possibly. Coax drivers are sometimes very special.

You didn't happen to take a picture of the driver before it went away, did you?

Was thinking about this statement... I'm finding that the more I do, the closer I wind up to theoretical considerations about it.

I've always been one of those, that only had use for theory, when there were practical considerations involved with it. Never been much for "knowledge for knowledge sake", until more recently. But, I'm finding out more and more, that SOMETIMES the theory for ONE thing is EXACTLY the thing that explains SOMETHING ELSE, sometimes in ways that I would have never expected.

Of course, I was always one to try and "leverage" whatever knowledge I had. I remember one test in my college Audio Engineering course (taught by the great Dr. William Marshall Leach, at Georgia Tech)... I couldn't remember the electrical-analog formulas to solve one question regarding determining the efficiency of a driver given basic parameters... so I did some quick "plug and chug", and solved the problem using mechanical engineering THERMODYNAMICS formulas. Came out with the right answer, too! Got credit for it too- Dr. Leach said he had to look at it a while (and look something up in a book, too), to determine what was going on- but he determined that what I did, basically did EXACTLY what the EE "electrical analog" formulas did, when boiled down to basic fundamental theory. After all, it's all RELATED, at some basic, physical level!

Never let it be said, that I can't make the most out of random stuff I wind up with! :D

In any case... with my newest projects, I'm starting to realize both a) the SEVERE LIMITATIONS of current speaker technology (2% efficient on A GOOD DAY? What OTHER industry could get away with THAT kind of power waste?!), and b) how NECESSARY it is to know the theory behind what I'm building, in order to get it TO THE BEST it CAN be. Hopefully, one day, I can actually contribute something to make a fundamental improvement in this stuff- here's hoping! :scratch2:

But, it is nice even now, every once in a while, to just take a bunch of random components and see what the heck I can make out of it, and what it can do afterwards... :banana:

Gordon.

Gorden, while reading an older post a gentlemen asked you if you had surrounds that would work on an E-V B-15 (Sentry III). How did that work out? I'm in the need of some myself. These cones seem like the would be rather hard to keep centered without shims. But then there is the dustcap question.

[plan9]

Howdy Gordon,

I have a question...a pair of Akai SW-T70 I acquired a while back did not function, (they were in a pawn shop, at this time) when we opened them up the caps were blown apart. the pawn shop owner said come back later and i will have them repaired. I did so, and when I came back,sure enuff they were working. I bought them for $80, and took them home. I dont believe he put the correct caps in there,(neither does he). do you know what caps would be suitable for these x-overs. I dont recall whats in there now. they sound ok, but cud they sound better?

Patiently awaiting that day. And sure it's coming.

hi Sir Gordon,

Methinks i've seen your posts in some other sites. I had a question about double advents and just followed the trail of your replies to past questions and found my answers. The Double Advents do kick ass. I tried to A/B test a stack with a pair of Jubals and they kicked the Jubals to smithereens. (or was that a fair test. :D)

And yes speakers should be brought back to their original pristine condition instead of being trans-mogrified and monsterized into another model. :smoke:

best regards,
Foo

I had some 18 and 15 inch cast frame EV drivers up until a few weeks ago pending recone....about 6 or 8 pairs in total.....finally decied I'll never get around to it...and even if I did...what would I do with them....so out they went.

The price of drivers these days does not make reconing these things worth it in my view....even with a whole sellers account from a speaker parts supplier...it just wasn't worth it...time..cost...etc.

With folks dying of lung cancer every where you look....working around the hazardous chemicals involved in the process is another consideration.

Hello, Gordon. I hope we cross paths someday.

This is a tricky problem.

The ONLY foam surrounds I can locate, that physically will fit the EV 15" woofers (right dimensions in diameter), are FLAT inner edge. Problem is, that the EV woofers have ANGLE edge...

Now, I've managed to MAKE this work, and work well... but it makes it hard for the person without all the tools and special adhesives we use for reconing. What you have to have, is an adhesive with LOTS of initial tack, that sets up quickly, but is NOT an "instant contact" adhesive (because you WILL need to shift it around a bit). Those types of adhesives are pretty specialized... we have one specifically made for reconing speakers, but it's not something you can buy at a hardware store. And unfortunately, it doesn't transport well in small quantities (dries out QUICKLY if not in a large sealed container, for whatever reason)...

So, the answer is: I COULD refoam those if they were here, as could any reconing shop that had the right "foam glue" adhesive (the Waldom number, BTW, is AA-74 for the glue like we use)... but, I'm hesitant to send out just the surrounds, for anyone else to try at home, for the reasons above...

Regards,
Gordon.

Hello, Gordon. I hope we cross paths someday.

Should be able to go to the AK Southern Fest... http://www.audiokarma.org/forums/showthread.php?t=112727&page=4

Will bring all sorts of wacko stuff too, if possible! :banana:

Gordon.

[DaWoofer]

Thanks Gorden, I seem to have a hard time getting them to center anyways. I might just send this pair out.

[centralflori]

Hey Gordon. Good to see you here!:yes:

[Negotiableterms]

Another of AK's technical resources, and very welcome because of it!

[onwardjames]

while I've never met or spoke to the man, I've referred countless friends to his expertise on speakers.

While I'm at it, Gordon, what replacement caps would you use for my Sansui SP-2500X's. They sound pretty lousy stock, and after a recap using cheap RadioShat (s.i.c.) caps they really seemed to improve. Wondering if Solens or something fairly nice would coax out some more sound. Love the build quality...can't say the folks at Sansui didn't try....

Oh, and my newly acquired Boston Acoustic A-60's.. what kind of caps would u recommend for these sweet lil' girls??

Sansuis of that era tend to use garden-variety electrolytic caps... my inclination would be to replace at least the midrange and tweeter caps with poly caps. The Dayton polys from Parts Express are my usual go-to cap in this application. Or, if you can't find the value you need in the Daytons, the Jantzen caps (also from Parts Express) are IMHO, pretty much interchangeable. Both are good types of caps.

Probably the same for the BA A60s... should work just fine.

Gordon.

I second that!! He refoamed my Infinity 2001's, and they look like new...sound like it, too :banana:
