5jr+'s up and playing (surprised)

soundfreak1

Replaced tweet in new ACCUSITION JR+'S AND I MUST SAY WOW FOR A BOOKSHELF. I'VE HAD MANY MANY SMALL BOOKSHELFS IN THE PAST, KLIPSCH,ADVENT, JBL,EPI,ESS,B&W ECT. THESE REALLY SSURPRISED ME ESPECIALLY THE BASE. PROB. THE BEST BASE I'VE HEARD IN ANY BOOKSHELF ALL IN ALL VERY NICE JOB POLK .I CAN HEAR WHY PEOPLE STILL USE THEM. WOULDN'T MIND TRYING THEM IN MY HT SYSTEM. SHORT OF REPLACING THE SL2000 WITH RDO94'S IS THERE ANY WAY TO SMOOTH OUT THE TWEETS?

Vintage Monitors always did play above their price point. Now on the used market some 20 years later, there isn't a better sounding speaker going in it's price range and several hundered dollars above.

I will probably never get rid of my 5B's.

Now add RD0's and some decent caps in the crossover and prepare to be WOW'ed again.

I love my 5Jr+ Series 2 (Piano Black), they were my first pair of Polks. I just recently loaned them to a friend of mine who has them hooked up to a Marantz 2238B. I helped her set it up and they sound great with the Marantz. I told her she can have them as long as she wants, as I have upgraded to 7C's & SDA II's, but that if she ever moves outta state or decides to get new speaker she'll give them back. Congrats on your 5jr+'s!!!!!

I would not consider them small.
These are pretty good size speakers.
I have the 5's (with SL2000) that are few inches larger than the 5Jr's and have amazing sound.
Currently using them as my surrounds in HT and I like the bright tweeters. They bring surround sounds like broken glasses, winds, explosions etc... very nicely.
On smoothing out the tweeters, I read somewhere that covering tweeters with fabric helps. You can try with different fabrics and see what works best.

heiney9

The problem you have with adding fabrics, foam, attenution is it radically alters other frequencies outside the natural 5dB spike at about 13kHZ. SO you end up causing a different issue trying to fix the original issue.

There really isn't a fix that doesn't create other issues. Except getting the silk domed RD0 tweeters.

Bingo.:biggrin:

FIGURED AS MUCH! I downloaded the schematic and there isn't much to them ( compaired to the rta's ) might be a good learning exp. Moding them. Got to look close to the xovers as to disasembly. Cap's can't be too much. What would u recomend reguarding cap's? The rdo are a given I guess. I have them in my rta 12c's and like them a lot. I can switch them into the Jr's and see or hear the diff. Right away befor i buy but I think your right. With a little dynamat thrown in these might get stupid good, they are surprising just stock.

heiney9

I used Clarity Cap PX for the high pass and Solen for the low pass and Mills resistors. I also splurged and bought a set of Larry's rings and tweeter brackets. And of course the RD0 tweets.

Yea, I'm always pleasantly surprised when I hook up my 5B's.:biggrin:

soundfreak1

The rdo's r deff. In the future for these, do the sl2000 have a market here? Could partially from the rdo's.

heiney9

Sure they do, IIRC, about $15-20 a piece is the going rate.

soundfreak1

Make that "partially fund the rdo's."

soundfreak1

Thanks.that would help. Might have too put them up when I get the rest of the money for the rdo's.

heiney9

The boxes the RD0's ship in, make perfect shipping boxes for the sl2000. Fit like a glove.

soundfreak1

That's a great idea h9, was just thinking about to ship them properly. That was a great idea, glad I thought of it.lol

When you call Polk to order the RD0's be sure to tell them you're a member here. With the discount they are really not that bad price wise. I put a pair into my 5B's, used Clarity Cap PX caps and Mills resistors and love the sound.

I was not aware of the discount for forum members.
How much are we talking about?

Are you sure your 5jr+'s have SL2000's? Mine came from Polk with SL2500's.

EDIT: I just checked the schematics in the Vintage Speaker section and found mine are technically "5jr+s" where that "s" must mean it has SL2500's from the factory.

I guess we are creating a problem trying to show 5jr+ speakers in the plural form with an apostrophe s ('s). There is a 5jr+ with SL2000's and a 5jr+s with SL2500's.

Just noticing that the only difference from 5jr+ to 5jr+s is a 13.5uf cap for the SL2500 instead of a 12uf cap for the SL2000.

What is the RDO replacement for the SL2500 ???

Can't remember the discount but shipping was free in the Continental US.

Just found this: http://www.polkaudio.com/forums/showthread.php?121702-Differences-between-SL2000-and-SL2500&highlight=SL2500+replacement

If you decide to replace tweeters, and also decide to replace caps (caps are old and should probably be replaced either way) you can buy 13.5uf caps and "move up" to the RDO198-1. (Also remove and jumper the polyswitches).

You'll pay the same approx $50 each for the tweeters whether you go 194 or 198, and the bigger cap would only cost a couple bucks more than the 12uf.

For about $130 you can move those speakers to the top-shelf.

Mystery

From what I read:
SL2000 --> RDO194
SL2500 --> RDO198.

$130 -- hmm...
Expensive upgrade...too much for my Monitor5.

heiney9

Inspired, have you priced caps lately? I was a little surprised when I was pricing out some caps and resistors for my newly aquired RT25i's (Dayton and Clarity). Almost $60 for pretty much the same values as in my 5B's. Although the RT25i's have an extra resistor so that's about $9 extra right there.

H9

soundfreak1

I think its 20% if memory serves me.

soundfreak1

Not a bad suggustipm inspired..

soundfreak1

The discount IS 20% I believe. And they deff. Have sul2000

pdxfj

IIRC it was $40 something for each 194 and free shipping. Very much worth the expense. Much smoother sounding tweeter.

Well, you could have some 5As with a Peerless! I agree with Brock. What a value 5s are! In the collection permanently. In fact, I find myself listening to these more and more as time passes and there are a LOT of other "vintage" speakers in my room!

Go for the RD's!

I haven't replaced the SL2500's (yet), but finished the caps, resistors and Dynamat Extreme today (this thread finally got me off of my butt to complete this "rainy day" project ). I also have TFLF rings and new BRGM gaskets for a future upgrade.

I upgraded the left crossover about 5 months ago to contrast and compare the sound in stages. The 13.5uf Sonicaps and 1 ohm Mills Resistors were purchase 14 months ago from Sonic Craft during one of their sales for not much over $30, but I see they are a bit higher now.

Don't forget, you can resell the removed SL2000's or SL2500's (depending upon your exact model) and recoup some value to defray the cost of the mods.

The improvement to the left speaker was noticeable and worth it. As you can imagine, the right speaker just completed today sounds like a fingernails on a chalkboard.

The 2000s can bring even better money on ebay, if no one bites here.
