Well, it's time to give something back to those that entertain me throughout the year. I have usually given away mint condition electronics that I find in my travels or dumpster diving....here's a refresher:
Technics SA-500 Receiver, won by HALO.
Pioneer SX-450 Receiver, won by Shack.
Sony STR-7055 Receiver, won by Nikolas812.
I figured I'd try and mix it up for this round and am offering my own Polk Audio LSi7 Bookshelf Loudspeakers AND a Polk Audio PSW125 Subwoofer*. They are in mint condition, black and include original boxes and literature. The cabinets have been freshly waxed and polished....they look outstanding.
*See below for the subwoofer details.
The LSi7 is the real gem of the entire LSi lineup for me...even moreso than the LSi25. It's one of the top ten bookshelf speakers that I've owned in my travels. You never expect much from a bookend and this little guy will knock your socks off.
We usually have Karma requirements and this is no different but with a little spin on it. I've enlisted the help of the Dark Wizards that populate the bowels of Polk HQ to provide some trivia.
It's only 12 questions and you don't have to answer them correctly but challenge yourself and see if you can find the answers. At the very least, please say that you are "IN!" and I'll add your name to the list. The first person to answer the most questions correctly will get a secret prize.
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
Good luck Polkies.
The Karma drawing will be on December 17, 2009.
*12/15/09 - I'm going to add a Polk Audio PSW125 Subwoofer to the mix. For those of you that want more low end response....here you go. The PSW125 will provide enough bottom end augmentation to fully immerse yourself into the whole experience. I'd suggest playing around with the settings as when it's tuned right....the blend is not too shabby.
It originally was a PSW10 but in usual Polk Audio fashion, they made this Karma even better!!! I enlisted some help from Hedy Klopfer and Jeff Nemec at Polk HQ to find some original packaging for the PSW10. Jeff spotted a stack of subwoofers with no home and asked if a better subwoofer would be ok. AS IF!!! So, long story short, you are getting an even better subwoofer. How's that Polkies!!!!
