Rogers DW2 Subwoofer connections

[TheFinisher]

I ordered the caps this morning along with a bunch of others for a Philips cd207

I’ve not looked at the maroon ones

Great! The maroons will be film capacitors and so won't need changing.

Sorted now , up and running but the sub makes very little difference though I can feel that it’s working.
Perhaps those very old Alcap capacitors need replacing?

Ok

Orange - input
Blue + input

White - satellite ( jr149 )
Blue + satellite

Since all three blue wires on the crossover input, output and to woofer are connected together, so the blue wires should be negative (-) and the orange wire should be + input.
Please connect the amplifier output + to orange wire and the amplifier output - to blue wire. Also connect the JR149 + to white wire and - to blue wire.
This may bring the subwoofer and satellites in phase and improve bass response.

Thanks , that’s how I have it wired now . 👍🏻

 

[Galu]

And the bass has improved?

 

[TheFinisher]

I haven’t had time to try it yet .

I see two resistors and a 3 positions selector on the low pass filter to set woofer level of 0dB, -2dB or -4dB.
Maybe it would be better to move it to the high pass filter?

I have only just joined the forum as a result of finding this thread - following my retirement I have just recently ressurected my old 1980's system which has been in storage for the best part of 40 years and includes a DW2 - I even have the original typed instructions which I will try and insert here. Happy to post some photos is anyone is interested - it all works a treat and I can't believe how brilliant it sounds after all this time! Cheers Andy, Yorkshire UK

Thanks @Famandy for your contribution to a thread which was left unfinished by TheFinisher!

 

[Galu]

Happy to post some photos is anyone is interested...

Go for it Andy! 😎

 

[Famandy]

Here you go - stands have been updated to Attacama with dedicated LS3/5a baseplates, otherwise all is pretty original from mid to late 1980's - eagle eyed will spot the Samsung blu ray recorder and the Cambridge Streamer

 

[Galu]

Wow!

I'm impressed with the way the incorporation of your retro equipment has resulted in a system with such a modern vibe!

P.S. Next to the DW2 subwoofer, is that a big congratulatory 'A' for Andy?
