I have just joined the forum to try and find out more about my JR150's and a DW2 Subwoofer. I had a pair of JR149's in the 80's and stupidly let them go.
I recently regained an interest in getting a sound system again rather than relying on the Pioneer surround for all musical things.
I saw an advert for the 150's complete with DW2 and on impulse bought them. Now I have to make them work properly.
I have the 150's connected to a JVC J-SA22 amp. I understand the DW2 should be connected to the amp and the speakers to the DW2.
The wiring on the DW2 does not have any indication as to what goes where.
Two chocolate blocks with four off wires each.
Orange/Green with Yellow trace/ Red with Blue trace/Red
Can someone point me in the right direction please

Hi Simon and welcome to AOS. I'm afraid that I've no experience of the DW2 sub. There are others here who have used one (JacHawk for one). Someone may know the schematics. I'll split this post into another thread where it might attract more specific notice.
Hi Simon, any chance of getting a picture or two up of the connections? I'm just a little lost as to the colour scheme of the cables. If you happen to have a simple multimeter (or a camera & screwdriver ) we can easily work out what's what given a bit of time. It'd make things vastly easier if you could open the thing up by possibly removing a drive unit as well.
At the end of the day it sounds like the crossover in the sub has a high pass filter that'll feed the left & right speakers. If we can't find any info it's simply a case of establishing the order of the crossover by drawing out the circuit (by you taking a picture or two again ) & then we'll get it sussed for you with little or no problems

I have attached two photos. To get to the board inside is rather more difficult. Strip off the bottom remove bottom speaker then remove a rather crude chipboard circle. Remove opposing speaker. Reamove foam that is stapled into position. Inside is a foam stuffing that covers the board. Not sure how to get the board out. If required I can strip on the dining room table tommorow.

Hi Simon, yes i'd appreciate it if you could strip the thing (this is only for your benefit ) so i can work out what's going on. I'll need detailed pictures of the wires connecting to the boards, the side of the boards with the PCB tracks & the side with the components.
As long as you give me that i should be able to work out what the proper connections are

Tomorrow I have to put my car back together. Something I am much better at.
I am a mechanical maintenance engineer by trade. I can handle 3ph and low voltages but once you get down to millivolts and resistances I leave it to the professionals. Being colour blind all I can say is there are pretty coloured lines round resistors!

Oh dear... Is there any chance of you taking bigger pictures & following directions on this thread upload bigger pictures & then use the [IMG} files in a post?
They aren't 100% clear, oh by the way, it'd be helpful seeing as you are in there to take a pic of the wires connecting to the driver in the enclosure & again where it terminates on the crossover.
We'll get there

The link above should take you to the images. The board is duplicated on the other half. The black pot in the middle leads to the outside and has three positions 0 -2 -4 I take this to be db.
The white wire and the green with white trace are the speaker wires.
The two speakers are mounted opposite one another vertically and all the wires are sealed through the woodwork.

Hi Simon, well it looks to be sussed out chap Both crossovers are 12Db per octave which means that the connections need to be reversed to the satelite speakers (due to phase issues) & looking at the wiring colour they have done just that
Here are the connections... remember they are the same for left & right speakers
That should sort you out, please let me know how you get on
E2A:- I just had a thought... Depending on where in the room the sub is compared to the satelites you may need to reverse the positive & negative connections to each satelite or you might get cancelation near the crossover point. Best to try them both ways round & settle for the one with the most bass (in phase at the xover point). This will as i say though be dependant on the distance of the sub & satelites from your seating position
