Yea, sorry...I'll do that now. The original thread will get updated.

Q: What vegetable is Matt Polk so allergic to that he keeps the phrase “No ------“ written in five languages on a card in his wallet?

A: Eggplant. It has landed him in the hospital on at least two occasions where I (Stu Lumsden) have been present.

Q: What was the first tweeter that Polk Audio made and sold?

A: A Polk-built version of the Peerless K010-DT (black, silk dome with hole at apex). We built into the monitor line for about 6-12 months w/o telling anyone about the change so that when we unveiled our own tweeter (SL1000) any stuffy critics who might be tempted to say that our manufacturing just was not up to that of Peerless (of Demark) could be told that they had been reviewing and enjoying Polk-made K010-DTs for about a year and had not heard the difference. I even had to add dirt and dust to the latex dome treatment so that when it was applied it look like what we were getting from Peerless at the time. - Stu

Q: What extremely rare Polk Audio product was only manufactured from 1978-1979?

A: An RC HP network box designed to filter unwanted + 100KHz info to ground to prevent some amplifiers from going into oscillation when attached to our Soundcable (aka Cobra Cable). - Stu

Q: What was significant about Polk Audio's introduction of the famous Cobra Cable in 1977?

A: Polk Audio was the first audio manufacturer to sell upgraded speaker cable, which subsequently started the cable wars of today. -Al

Q: What was the crossover architecture difference between the Monitor 5, 7 and 10, in the original Monitor series (circa 1979)?

A: NOTHING! The only model to model difference was the level resistor on the tweeter. While it seems formulaic it was actually the product of quite a bit of listening. -Stu

Q: What was the first speaker that I (Stu Lumsden) voiced entirely on my own and in about what year?

A: The model 5jr ~ 1982. I intentionally left the Dacron stuffing out so Matt would have something to change on his first listen. This was the first design that Polk used that had an inverse polarity tweeter. The 1st-order LP/2-order HP combination and the tweeter’s low end combined to produce a phase shift that blended much more smoothly with the tweeter flipped. It was incredibly smooth sounding. The Sensible Sound panned me. I still have the review somewhere. We sold TONS of that speaker. -Stu

Q: What car audio product never made it to retail yet toured the nation as part of the eventual new lineup?

A: Al says it was a 12" subwoofer but I think his memory is bad. Jstas probably knows....did they ever have a 12" subwoofer before the SR series?

Q: What does the "SL" stand for in the SL series of tweeters?

A: Sandy Gross approached me in the plant one day while I was working on the machinery to build the tweeter. He asked if I would be OK with the idea of calling it the SL1000 for obvious reasons. But he really was attracted to the fact that SL1000 sounded like a Mercedes model designation. The fact that it had relevance to its designer was justification enough. -Stu

Q: What does the "MW" and "RD" stand for on the bass drivers?

A: MW = Mid Woofer and RD is just a useless inventory label for replacement parts.

Q: Who developed the RM3000 phased array tweeter?

A: The tweeter was not very special. It was the fact that the tweeter was pushed back to “phase align” it with the driver. -Dave Glotfelty/Matt Polk/Stu

Q: What does A.I.M. stand for and what did it do? (SDA Question)

A: Audio Interface Module. I'm still waiting on Matt's explanation.

What was the order and aligment of the crossover in the original RTA12?

A: 4th order Gaussian. It was developed via a Fortran computer program that Matt wrote to run on his HP hand-held calculator in 1979. It was the most advanced "computer" that we owned at the time in R&D. A calculator....no kidding. - Stu

Why ya gotta pick on me?

Yes, every sub line had a 12" subwoofer except the original Mobile Monitor series IIRC.

The one I do remember is that the new DB series when it was first released several years ago was shown with a 15" sub in the original white papers and such but I don't ever recall seeing a 15" sub released. They instead went with DVC 8", 10" and 12" subs as well as the usual SVC models. I don't remember if they cam in 4 and 2 ohm voicecoils though. I think it was just 4 ohm. I only remember that because I was disappointed. I thought the DB line with the super light cones was perfect for a decent 15" sub. Subs that size are notorious for cone breakup under extremes. The cones are heavy and they take a ton of power to move. But the new DB series had a very light but very rigid cone. It would have been perfect for a 15". Instead they made a 15" in the MMC series (MOMO Carbon series) and I never really liked it. The 12" MMC subs out performed them.

That's it....the 15" db series woofer. Thanks John!

WOW John!!! Send me a copy of that memory chip in your head. Mine is burned out.;)

I love reading those answers, especially the "Polk History" Cronicles.
Sometime, if you have a chance, it would be great to hear more of those great stories.

Regarding the "Polk Peerless", any record of the S/N's or something to identify them?
Or are all the 'Peerless' tweeters that people have been referring to as the "American Version" with the hole in the dome "Polk Peerless"?

Merry Christmas :)

[dorokusai]

The hole is the Polk Peerless but the early ones may or may not have the hole. There is no record of serial numbers for pretty much anything from those days.

[MacLeod]

I still say it was an 8" SR sub.

There was one featured in a demo car in Car Audio and Electronics a few years ago. And I couldve sworn I saw them in another demo car somewhere else. Maybe they were misprints or something.
