Speakerlab History Project

I wasn't successful in opening the zip file. I get this error message: "The archive is either in unknown format or damaged." I tried using both WinRAR and 7-Zip and had no luck. Anybody else have problems, or success?

I'm interested in finding out more info on my pair of DAS3 speakers, which I like very much.

Thanks!

No problem opening the zip file here in Windows 7. XP and above will open the compressed file directly in File Explorer.
 
I'm about to leave for work so don't have much time at the moment but I'll check it when I get back. I wonder tho, is your os complaining about the zip format or the ods format of the spreadsheet?

I haven't found too much on the DAS series except for what's in the '86 catalog. More later, gotta run.

Cheers,
James
 
Bratwurst7s, thanks.

My OS is not complaining, the apps are. A few more things I did to no avail: Shortened the filename (SpeakerLab.zip), re-downloaded, and also executed in a root directory (i.e. no long string of directory names).

WinRar:
"F:SpeakerLab History Project v1.02.ods.zip: The archive is either in unknown format or damaged."

7-Zip:
Error message says, "Can not open file 'F:\SpeakerLab History Project v1.02.ods.zip' as archive.

Win7 Windows Explorer:
Right click, select Open With, select Windows Explorer. Error message, "Windows cannot open the folder. The compressed (zipped) folder 'F:\SpeakerLab History Project v1.02.ods.zip' is invalid."

Thanks, I appreciate your help.
 
Hmn. I was just able to dl and unpack the zip from here at work without problems. Do you have OpenOffice or LibreOffice installed? I don't know if the ods file format is supported with MS office products, in the past MS has gone out of their way to make things difficult for open source file formats. I used the ods file format specificly because openoffice/libreoffice is a costfree download and there are versions for windows, mac and linux. Thus nobody needs to pay for a program to access the file.

The only reason that I posted it as a zip is because the attachment manager here at audiokarma didn't seem to recognize the ods file and wouldn't let me upload it directly. But it's small. If you still have problems feel free to PM me and we can make arrangements for me to send it to you directly, uncompressed, after I get home from work.

Cheers,
James
 
Those of you with more program savy than I can laugh about this, but I've finally learned how to link a sheet entry to an other with a hyperlink. I wanted to do this from the beginning but couldn't figure out how till just now.

What that means is that I'll start linking the drivers in each model listing that I've been able to positively identify to the entry in the appropriate driver page with a cntrl-click. That will take a week or so, so stay tuned to this channel for our next episode... where Jim tries to wrestle this creature to the ground without getting bitten.

Something just came to mind. It's been a while since I've done anything in windows so please bear with me as far as syntax goes, but try right clicking on the file, selecting Properties, and check that it hasn't been set to read only.

No, I don't have OO or LO, just Office 2010. I don't see how the contents of the zip container would have an effect on unzipping.

No, it's not set to read-only.

I tested my versions of WinRAR and 7-Zip again today and they successfully unzip numerous zip files. Let me know if you have any more thoughts, and if not, I'll take you up on your offer to send it to me directly. Thanks.

I agree, I was kinda reaching there. But you might need to DL LibreOffice to access the file. I can't say for sure, I don't know how well MS exel will read an ods file.

http://www.libreoffice.org/download/?type=win-x86&version=4.1.4&lang=en-US
Free download, no registration required.

I really don't understand why you can't open it, can only guess that it is some issue having to do with your archive program or my having uploaded it from a linux based pc and some kind of conflict? Darn PCs.

Let me know if you have any more thoughts, and if not, I'll take you up on your offer to send it to me directly. Thanks.

We can do that. Sounds like the easiest way at this point rather than fighting with unpacking issues. If you want to PM me we can trade email addresses and I'll shoot it over.

Cheers,
James
 
Bratwurst7s,

The Speakerlab Super 7 used the W1008P woofer in combination with the W1208R woofer, a midrange M654P and a LT2155 tweeter. I find the M654P listed as a driver and specs but no T-S Parameters. The W1058P woofer is later than any info I have.

Yes. That's the generation (of at least 4 distinct generations that I see) that I have. :yes:
Unfortunately that is a generation that I have zero T/S info for. :no:

This 6 to 9 hour time diff between here and the States sucks. You guys over there are just getting active and things are getting interesting, and for me it's time for bed. Gotta get up at 5am. I got a couple of year/model/driver pages hyperlinked tonight, hopefully I'll get the rest done in a few days and will post asap.

Speakerlab alum

James-

I'm following your thread with great interest. Speakerlab brings back a flood of memories.

I built several Speakerlab kits for personal use and for friends, including a pair of 7s for a good friend (old enough to be my father) I made through our mutual love of music and audio.

Johnny was a retired GM worker who had lost a lot of his high frequency hearing from years in the plant, but not his love for Jazz and Blues. We met when he answered an ad regarding a Dynaco ST-400 amp I was forced to sell, due to being an "impoverished" grad student.

There was a mix-up regarding the sale of the amp. Johnny drove from south of 8 mile in Detroit to my parents' home in Bloomfield Hills, MI, only to be disappointed to learn the amp had been sold. Johnny came with "cash money" in hand expecting the amp to be available. He felt bad; I felt awful. It turned into a blessing for us both.

To assuage my guilt, I offered to build for him the newly introduced Dynaco ST-150 (75w/channel SS). It was a win win. For less money than he was going to pay for the used ST-400, he got a brand new amp to drive his Large Advents. I got the fun of building the latest Dynakit using someone else's money. Johnny personalized it by having the case chromed.

From that moment on we became audio/music buddies. He wouldn't buy so much as a record cleaner without consulting me, while I looked to him for an education about Blues and Jazz. We'd go to audio salons (remember them?) together. We'd go to record stores together.

When I expressed a desire to go to Baker's Keyboard Lounge (Google it) he strongly advised me to never go without him. He didn't like the chances of a white boy alone south of 8 Mile after dark.

Shortly after selling the ST-400 and Bose 901s to fund school, I got the idea to re-assemble a sound system and DJ dances, parties, etc. to fund school.

I ordered 4 Speakerlab SKhorns and persuaded Speakerlab to send them to me with no shipping. They sent me a supply of catalogs (I wish I still had one) to promote their products in exchange for free shipping from Seattle to Detroit.

I knocked down the plywood shipping crates to enclose the backs of the cornerhorns. They still preferred true corners, but the false corners helped a lot. In '76, these were factory built from plywood with the aluminum 350 squawker, EV T-35 tweeter and 8 ohm woofer. They were painted black with the top hat enclosed in hardware cloth to discourage napkins stuffed into the mid-range horn and the disappearance of the Atlas compression driver (both of which happened prior to the hardware cloth).

Johnny loved those SKhorns, which I powered with another Dynakit ST-400 (300W/channel into 4 ohm load presented by two 8 ohm SKhorns/channel). I showed him how little power they needed to peel paint. His ST-150 was more than up to the task.

Ultimately, he sold the guts from his Large Advents and purchased S7s, without enclosures. I helped him convert the empty cabinets to S7s, which gave him the horn sound he loved. Those efficient S7s sounded great with that much clean power.

I'll never forget the day he dropped the needle on David Sanborn's Concrete Boogie to test the newly completed S7s. As he did so, he said, "They say white boy's don't got soul, but this cat do" at which point the unmistakable sound of Sanborn's sax poured from Speakerlab's #2 speaker.

Many hours were spent in Johnny's basement as the professor educated the student. Miles, Trane, Dexter, Art, Sonny, Brubeck, et al, I understood and love to this day. Sun Ra, and a few others, were acquired tastes I never acquired.

Johnny went with me on a few DJ gigs and had a blast. He's been gone for many years now, but the music appreciation degree and the memories remain. Music, which is the reason for audio, is equal opportunity. It cares not for distinctions based on class, ethnicity, religion, age or any other petty categorizations. As Edward Kennedy Ellington said, "There are two kinds of music. Good music, and the other kind." The same can be said of people.

The friends I've met through a love of music and the effort to reproduce it are invaluable.

If you already included this I apologize, but did you get your S7s new? Speakerlab will always have a warm place in my heart. Thank you for reminding me.

Hi Neil,

Thank you very much for sharing that with us. Just the sort of thing that makes me glad to have joined audiokarma. I envy you a good bit for having those SKhorns. The older brother of a friend back in Tacoma Wa. had a pair. We used to light candles on a chair placed in front of them and experiment with which songs could blow them out with a quick twist of the volume knob. Such are the abuses young guys put stereo gear through. There could have been alcohol involved, mabye, but I'm not saying.

Thanks for asking about my 7s. They are getting much better and sound fantastic with new mids and tweeters, but I've pretty much convinced myself that I need new 10" woofers. But it's nice to be able to listen to music again each day without getting angry about the condition of my speakers.

I agree with you about Speakerlab, they had a special thing going back then. It'd make me very happy to see them reboot and get that magic going again. Once again I haven't gotten a response to my email to them, but it's only been a couple of days, mabye they'll answer.

Cheers,
James
 
Bratwurst7s,

If the T-S parameters are not available, you may be able to find the source of the drivers and get from them. If not, you can ask someone experienced to measure the T-S parameters or tell you how. It's not difficult to do from what I've read, but I've never done so.

Good advice. I'm kinda going 1/2 & half in that direction. Here with this project I'm just working on collecting print info from old Speakerlab catalogs etc. Over on my rebuild project I'm saving my pennies to buy new 10"ers and some test equipment. Mic, tone generator, small amp, and software. One step at a time. Then I only have to learn how to use that stuff. :sigh: But I expect that the process will be fun. :yes:

The car is not a Lotus/Caterham 7. it's a Rotus 8 with a Buick/Rover 3.5L aluminum V-8. When I built it, Caterham didn't yet sell a "long" version. At 10" longer and 4" wider, the Rotus was a better fit for my 6'1" 200# body. At 1800# with 200+ HP, it flew. Were I to do it again, I'd do a Caterham 7.

Johnny would not have fit in the Rotus.

Best,

Neil
