What do you consider best vintage Polk speaker?

RTA11t for sure. 5jr+ was a great smaller one.

Most of the larger SDA models were quite nice.

Sold them all many years ago, and never cared for the SDA effect on stereo image. Not a failure, but something that some love and some simply do not love.:lurk:

I remember when the marketing guy came to our place years ago, and tried to explain SDA. When some of us questioned the validity of the "Processing" on Typical Studio recordings, rather than the examples given about using 2 mics in a concert hall etc as in the "white paper", we were told not to question the why of it but to simply use it as a selling point to move product.


Not sure where the cutoff for vintage lies, but 20 years ago they came out with what I consider to be one of their best speakers ever. Well mostly the entire Lsi line.
Those seemed to be the first "true" audiophile speaker, where component cost and cabinet cost were not on the chopping block.

The more commonly considered 80s and early 90s cabinets were done to quite a low price, with glue and particle board, that was substandard.
I remember then even using multiple Midwoofer parts numbers in the same speaker models, and doing all kinda iffy stuff with crossovers to save bucks. Nothing was ever discarded, it was simply recycled onto another speaker model, whether it belonged or did not belong.

Still a lot of the 80s models were quite nice!

I love vintage Polk speakers and the Polk Monitor 10 has to be my favorite of the vintage Polks, although I am not familiar with the Polk SDA or RTA series.

What is your favorite (best-sounding) of all the vintage Polk speakers?

I am curious to see the responses and see what Polks make the grade as the best Polks of all time.

Thanks.
I've stuck with my monitor 5s from 1980s ...good powerful sound for there size...7s are good too just bigger

I've noticed that on my monitor 5s....particle board VS real wood like on my older JBLs...but still very heavy solid speakers that kick ass....
 
Ok...your probably right.....what are the main reasons other than money?
Solid wood is unstable, it expands and contracts up to 1/4" seasonally. In addition, the cell structure of every tree is slightly different, which results in differences in density. In turn, that affects the acoustical properties. Therefore, the probability of each cabinet sounding exactly the same is low.

Sonus Faber has made cabinets from glued up pieces of solid wood, but not in a conventional way and the cabinets were not conventional boxes. Due to the intensive labor involved the speakers commanded a premium price.
 
Rta 12c gets my vote once again, can I compare them to another Polk? Sadly no. They came in a package deal, I was actually reluctant to take them, I was really after some equally old NAD stuff, he was selling. Ironically it’s the polks that were the gold in the deal, I think I passed along most of the NAD stuff.

Had fun doing the recommended mods, getting the RD 194 tweeters (whatever the replacement is), new caps, cat scratched fabric replaced etc. Must say the image and full range sound they create is just perfect without much screwing around, they don’t relegate you to just one sweet spot.

Some speakers are so resolving you get annoyed when a recording isn’t top notch. These sound heavenly when it is, and tolerable when it isn’t. Great speaker to have in the quiver.

What can I say, I had fun with huge capacitors!

I liked the Monitor 7's I barrowed. I have a pair of Monitor 10's I like along with a pair of 5jr's. The 5jr's acually sound really good connected to my 300B SET tube amp. Inwouldnlove to have a pair of RTA-12's.

I’ll keep an eye out! They show up from time to time in PNW, obviously did for me. 300b set=nice, bet that goes well with horn speakers too

I don't have any speakers with horns yet. But it is a nice sounding amp for slme music.
