I can agree with you on this, but not to my liking though : I've had a pair of Pentavoxes [after I tried a pair of Redline 140] attached to my MB7000 and they sounded fine, but that all changed when I tried a pair of Pentalabs III with my BM7000. I kept them, sold my Pentavoxes promptly and never regretted it; aspecially when playing loud.................πŸ‘

Has anyone ever experimented on how much of this is due to the tiny DIN connectors and the typically really thin cable you can comfortably attach to them? I usually laugh at high-end cable voodoo, but it's easy to believe that there are audible effects when you think of the currents that flow in the passive speaker cables...

Don't worry about it - even lowly 1.0mm2 wire has only 0.019 Ohms/metre resistance. A 2 metre speaker cable will only be 0.076 Ohms!

You could also consider adding a Beovox Cona subwoofer to any passive speakers you use.

Smart4rse!!

What's even worse is I that even knew that - I didn't have to look it up. (BICC Tri-rated wire which is dual rated as 18AWG or 1.0mm2 is actually 0.0195 ohms/Metre) - How sad's that!😳Erm

Don't you think we're getting a little over-technical considering the OP only wanted to know which speakers to buy?

Again, I would recommend a bigger old pair of BeoVoxes, such as S120s or as Peter says, M100s...

thanks for all the responses! good info. i went to the local b & o store today to drop off a blown cx100. the guy showed me the 4000's. impressive and good looking. he said they were $4,000!! must have misheard him say on the phone that they were $2,500. also looked at the subwoofer ($2,900) anyway, alex posted that he uses non b & o speakers with his system. i did not know this is possible? how do i accomplish this? do i have to splice the speaker wires? also i did not understand the technical discussion about the cables. is something i need to know? thanks john

Johnny, any 4 to 6 ohm speaker pair (without amps) rated at about 80 to 120 watts RMS should be fine for your needs. Connect them to the 7000 with good figure-eight wire, your B&O seller will be able to point out where the positive pin and the negative spade are in the sockets --- he/she may even wire up some leads for you.

Non-B&O brands are good too, but hear them first!!! I'd suggest to listen in a similar sized room with similar furnishings to what you have---sound bounces of smooth shiny surfaces(!!) and more bounce equals less reality. Some sellers have carpets, thick curtains and sound-deadening furniture to give the impression that loud is great. Ears are just as important as other senses --- as they go (through deafness), you'll miss them!

Just to add to what Goldfrog said, the two-pin DIN B&O adapters are found easily on ebay.  If I recall correctly, the little round pin is positive, so the red speaker wire gets connected to that.  Then the black wire gets connected to the large rectangular pin.  Connecting non-B&O speakers to the system is pretty simple.  Don't get speaker wire that's too thick though, or the ends won't fit into the 2-pin adapters.  16-gauge speaker wire should be fine for your needs.

Here, this is what you need for the non-B&O speakers:

You can see the two little screw terminals in the plug.  You just strip the a little bit of the plastic covering from the ends of the red and black wire and insert the copper wire into the little screw terminals.  Then tighten the screws.  That's it.

 And no that technical bit going on about the speaker wires wasn't anything you need to know.
