Help required for B&W DM 620 Speakers

[RossM]

Hello,

I appreciate you may get some pretty basic questions on here - sorry if this is very amateur, I am trying to work my way in!

A friend of a friend was clearing out his stuff before he emigrated and had an old set of speakers he was looking to get rid of - B&W DM 620. In terms of the outside they have been marked a fair bit but he insisted they still worked, allowed me a listen and they sounded great so bought for £50.

I am now looking to connect them to an audio receiver and they have four connectors in each speaker (see photo). Most of the videos I have seen online show either two connectors, or 4 with 2 red/ 2 black - could anyone give me advice on how to connect these through? Should I buy red/black connectors and connect this way or do I use open wire to connect these? And with the 4 ports, most advice I can see online connect 2 of the ports to the receiver and 2 to the other speaker, is this the best way to get maximum use from them?

Any help would be greatly appreciated, cheers!

This article gets technical but there's some nice diagrams on the first page that may help - Bi-Wiring From Amplifier To Loudspeaker | Audioholics

The two jumpers are missing from what I can see.

Connect the two +ve posts together and the two -ve posts together.

Now connect a +ve from the receiver to the respective connected +ve posts and the -ve of the receiver to the respective connected -ve posts.

Bi-wiring is a con and useless. Adding the terminals to the low pass and high pass terminals, rather then just one set, causes endless confusion, like it has for you.

use short wires to short out the + together and a separate wire to join the -
then use a banana plug connectors to a single wire (+ & -) to receiver
or just buy something like this :
Dayton Audio PJMP-G Dual Binding Post Jumper Gold 091-650

Here's a link to the manual for your speakers. You may find it useful as it has instructions for how to hook them up. http://bwgroupsupport.com/downloads/manuals/bw/DM620-DM630-DM640-OM.pdf
