I am thinking about adding a non B&O passive sub woofer to my 7700. I currently have a pair of Redline 60.2 connected as the primary speakers, and a pair of CX50s as secondary speakers.
Does anyone have any experience with adding a subwoofer? I'm not really sure about the best way to do this or if it is even possible. I imagine I'd need to splice cables into each other, or sacrifice my secondary speakers in favour of the woofer. Is there enough output to drive all 5 speakers at once?
Any my ideas or suggestions greatly appreciated.

A passive subwoofer could deffinetly be connected parrallell to spekaer A output with yone our Redlines. but if you want to run all 5 speaker, my recommendation is that the 60.2 should have a passive HP crossover,so the impedance load in the low frequences isnt to heavy for the amp ( asumed that the passive sub already have a LP filer built in )A simple 6dB Hp crossover for your 60.2 could be done with a simple capacitor .Its 25 years since I did the math for it, but i amsure there are people here that can help you with caps suggestions.Passive subs have disadvantages, as it will be tricky to levelize them propertly, either the sub or the other speakers needs to be levelized with resistors.I have a large passive sub in my living room, I run it more or less active from a separate amplifier that is connected to pre out from my home cinema amp, just because of the ability to levelize it twoards the LCR speakers.
If crossovers, or adding capacitors in the chain seems complicated for you, then just hook up the sub parallell to speaker A output, but stay away from run all 5 speakers at the same time, is my advice.
My re-capped M75 are my precious diamonds.
Another VERY simple solution without crossover is a speaker switch for speaker output BThat would make it possible for you to switch the speaker out B between the sub and the CX speakers.
In that way you wont need to sacrifice the lovely CX speakershttp://www.conrad.com/ce/en/product/350732/B-TECH-BT-12-SPEAKER-SELECTOR
