That's only the asking price, not the selling price. It's yet to be determined.

Yes, basically Monitor 60s, but better with real wood veneer... I hear...Expect that there will be bumps in the road. Choose to not let them rattle you.

I looked at my for sale thread from March 2014 which has some photos. I had mentioned in that thread that I understood the difference between the t90e and the Monitor 60 was the euro version had real wood veneer (because Euros wouldn’t buy a speaker that had vinyl) but I can’t tell from the photos. Sonically identical to Monitor 60.

Polk SDA 1 speakers "fully upgraded": https://sacramento.craigslist.org/ele/d/sacramento-polk-sda-1-signature/6899187590.html - $400

"Very nice Polk SDA 1 Signature Speakers. These came out after the SDA-1C and right before the SDA 2. They have been completely upgraded with 4 new RDO-194 tweeters, fully upgraded crossovers with mills resistors and SoniCap capacitors. New binding posts as well. This is hundreds of dollars in upgrades, and they sound amazing. Tops have minor wear, but overall in quite nice condition. Includes original SDA cable." -

Actually they are transitional between SDA1 and SDA1a. The brass plate covers the port holes they glued dowel rods into. They are nice speakers with sonicaps I have a pair. -

Buyer beware!

Demo required I guess.

If they work, I feel that's one great deal.
Most people just listen to music and watch movies. I EXPERIENCE them.

Issues with their capacitance, they frayed and short circuited easy and some other things.....
A cool “display item”, but I wouldn’t use them personally.
Google displays a few threads here with comments from @VR3, @F1nut and then some other forums have references.
When new they were great, but again prone to short circuit or have other issues...
Direct quote from Jesse (on Hoffman forums)Polk Cobra Cable loudspeaker cable
Stereophile review: 1978 (Vol.4 No.3). Highly capacitive, this distinctive-looking Japanese-sourced cable blew up many amplifiers that weren't unconditionally stable. Nevertheless, it blazed a trail followed first by Bob Fulton, then by Monster, then by countless others."....not everything that can be counted counts, and not everything that counts can be counted."

Looks like they are already gone...

I'd defer to the "blew up many amplifiers that werent unconditionally stable"..... over "blazed a trail", but thats me.
Again, cool stuff to have as a display piece, wouldnt use it. My buddy's shop got some in a trade and I warned him off from using it too. Think he's got it hidden away somewhere..."....not everything that can be counted counts, and not everything that counts can be counted."
