I am trying to recreate the old SDA CRS model - trhere is nothing like them especially with a carver magnetic amp behind them with the holography. But the passive Radiator is tough? What should the weight be? there are no specs available for the old polk drivers. I already have the original crossover design from 1986 and the drivers are ordered except the PR which is not available from polk and I havent the equipment to figure them out. there are tons of 10 PR's available what may be the most efficiant way to make this work out?

The middle drivers (in the photo) are SW100's.
I have no idea about the other two.

Please explain how you are re-creating the CRS+'s.
I recently purchased a pair of these used from Hoosier21.
Yes, they are fine, fine speakers.

Plz give all the dirty details of the project - including
why you are recreating vs buying used.

You could just buy these and save yourself a lot of hassle.

DEQ15,

I have an original set of blade/blade CRS+'s in black with original Polk stands. New, this was an $1100 setup.
I'll sell them to you for $800 and you pickup the shipping costs.

Condition is very good. New replacement Polk SL2000 tweets too.

Lemme know.

Ron S.

Note: The stands are critical to proper setup.

That is a fair deal but I cannot afford it at this time. can you tell me why the standa are critical? my pla is to fly them from the celing anyhow - independant of all surrounding objects. Do you by chance have the paperwork that comes with them? - I am a pretty good cabinet maker and I think the solid oak will look better than the flake-board and formica the originals have - it will be interesting to see the effects with regards to resonance.

Deq,
Yes, I have the original paperwork - including schematics.
Placement is absolutely critical because of the rear passive radiators. Distance from rear wall makes a BIG difference in lower end. Also, being a book-shelf type speaker, the height of the speaker is critical for SDA effect. You want the tweeters at about ear level.

My $800 price was a bit negotiable. Oh well. I love them anyway.

Take Care.

Ron

Here's what I paid for my three pairs of CRS+ speakers, all 1989 models with pin/blade interconnets:

Pair 1: Very Good Condition, black oak cabinets. Some minor wear, nicks, etc. on the wood veneer. A little black wood stain brough 'em back up to "like new" condition. Original Polk stands included. Price: $463.00 ($425+$38 shipping). Found on Audiogon.com. Currently assigned to duty as the center channel speakers of my home theater rig.

Pair 2: Mint Condition, medium oak cabinets. Cabinets were re-veneered in teak. Original Polk stands, boxes, and manual included. Price: $550.00 ($500+$50 shipping). Found on Audiogon.com. Currently assigned to duty in my home office rig.

Pair 3: Mint Condition, walnut cabinets. Cabinets were re-veneered in teak. Original Polk stands, and manual included. Price: $550.00 ($500+$50 shipping). Found on Polk Flea Market forum. Currently in storage (and they are NOT for sale).

While 4 to 5 Franklins is the usual range seen in the market place for this item, the buyer must be aware that some owners have a strong sentimental attachment to their speakers and that these owners expect to be compensated for their "separation anxiety" to the tune of an additional 3 to 4 Franklins.:lol:

DEQ15,

$700 + shipping for "speakers only" is quite do-able.
I live in Indianapolis.
Send me an e-mail: ronskarvan@aol.com
My tweets have recently been replaced with the new SL2000
replacement models (from Polk). They are not the silver-coil domes. I think the new Polk ones are better - personally speaking.

Mine are black, they are the blade-blade model, and they are the one tweet per cabinet model. Not the oldest..... not the newest.
But, they do sound very sweet.
