Congrats on getting those Scott's. I would keep watching ebay for a pair of Scott S 197 woofers or 197b Woofers. I have seen them up for sale from time to time and I'm pretty sure they are the same Woofer. You will probably have better luck finding the midrange driver as many of the smaller models share the same driver, Good Luck! Specs I found are: crossover is 700hz and 3500hz. Max input 125 watts. 4 ohms. Response 20hz to 25khz.

A little more info.
Thanks woofercooker, really appreciate your info. Going to spend a little to make them my main pair to use with an ultra linear EL34 amp I am building. Having no experience with selecting from a range of 15 inch woofers, I would also really value suggestions to buy new. My question is do I look for a speaker with an overlapping frequency range, like 20 to say 900 Hz? Probably want to stay under $ 300 per speaker, and where to source them.
FWIW, the cabs are solid walnut not veneered, so I'll be stripping and staining. A long project.
Thanks again.

I have HH Scott PRO 100 but have some problems. Main problem is that I doubt the crossover is not original and front switches are disconnected . There are some components ( resistors) soldered on switches, hoping original. Everything else seems OK. Cabinet, grill , speakers. ( Badges missing).
Does anybody have schematic of crossover network and wiring of front switches? Is it possible to publish it here or to be sent by email to me?
This forum is my only hope as I have been searching the internet for schematic for a long time and nowhere to find anything.
Thanks in advance

I have been on the road last few weeks but as soon as I clean them up. I will take pictures for you
I also have the phone number of the guy who has the other complete pair, if you want it.
I also put up a post with some pictures asking for help before I picked up my pair, just search for Scott pro 100.
I just liked the design and cabinet build quality.

I just grabbed a pair of these Scott’s. Came with a Kenwood receiver. Can’t find any info on these and don’t know if it’s worth investing in a restoration. They are not even close to original. The woofers have been replaced with Kicker subs. Original components have torn cones. Overall in rough shape. Any help is appreciated.

Hello all !
As I said in my introduction, I bought a pair of PRO 100 last year.
They were in a prety good conditions and I found the sound quality very good (even better than my PEL M3) so I used them as daily speakers...
I became a real fan of these speakers !!!
As their woofers wera not the right one, it tooks me almost 1 year to find 2 woofers (coming from 197B speakers) ; their foams were really bad so I sent them to a refoam specialist...
Waiting for the 197B woofers to come back, I checked also the crossover to find the references of the caps (to change them).
That's why I'm here now reading and answering this post...
I'd like to thanks Yamaha for the schematic above ; it helps me a lot !
But it looks like my crossover is a little bit different (may be yours is from PRO 100B ?) :
The main difference I don't understand is the added inductance (I called it "L ???" on the schematic)
I also didn't mesure the 3 other inductances to check if they are same values as on Yamaha schematic...
I just commanded the 2 caps for retrofit and I wonder if the sound quality will increase with the new caps and the 197B woofers refoamed...

Bonjour Bruno,
I too have a pair of HH Scott Pro 100 speakers with replacement 15" woofers. Do you know what the impedance of the original 15" woofers was? I'm pretty sure these replacement woofers are 8 ohm and the originals were not.

Hello Wray & Ting
As I wrote, I unfortunately don't have the original woofers :-(
I am replacing the unknown woofers that were on the speakers when I bought them by SCOTT 197B woofers (15'') because I think they are same as PRO 100 woofers.
I just tried to mesure the impedance on the 197B ones (not so easy with so big coils), I mesured around 7 Ohms.
Hope it can help you...

Thanks very much, Bruno, for the impedance info. If they are the same as the original woofers from the Pro 100 speakers, then my replacement woofers, which I'm quite sure are nominally 8 ohms, shouldn't measure too far off. Their other specs are probably wildly different than the originals though! I need to pull my woofers soon and see what's going on in those cabinets.
Did you get your 197B woofers refoamed? How do the speakers sound now?

I just popped out my woofers, and confirmed that they are Radio Shack 40-1035 drivers (8 ohm), and measure 7.5 ohms each. The odd thing is, my speakers measure about 8 ohms and 9 ohms each, where they should be 4 ohms. Do yours measure close to 4 ohms?

Regarding sound quality :
Yes I got my 197B woofers refoamed (very nice job by the way). I just installed one in the cabinet where I also changed the caps. The first listening was a little bit disappointing (means worst compared to the non-modified cabinet)... This last WE, I checked again and I felt the difference disapeared ? It may be need some time to break in ?
I also think that the previous woofers are good quality ones. The previous (and only) owner of my PRO 100 made them changed by a specialist.
Regarding full speaker ohms measure :
I will let you know...

Hi Bruno,
Glad you are happier with your refoam/recap job than when you first had the woofers reinstalled.
I too am puzzled why my speakers read 8-9 ohms when they are nominally 4 ohm speakers. If the woofers are supposed to be 8 ohms, both of us would expect the measured values to be closer to 4. In my case, I thought maybe the aging electronics in the crossover circuits could be to blame, but you at least have replaced your capacitors. I wouldn't expect inductors to change much as they age, and that only leaves the resistors and the drivers themselves. I should replace my caps as well.
