Hi, 

I have recently been given some BeoVox 3700 speakers and a Passive amp as well as a BeoSound 3200. 

The bass drivers in the speakers had perished and so i set about replacing them and the best replacements i could find were Celestion drivers rated at 100W (8Ohms, 8"). The original drivers were rated at 50w and sounded great, but i couldn't find anything rated much lower than 100w that seemed any good. Now, the tweeters and old bass driver weren't the originals, so I'm not able to go through B&O. 

Now the drivers have been replaced, they are not as punchy as before (understandably). I have also purchased another passive amp. My questions are as follows:

- What is the rated output of the Passive amp as I have seen various answers on various forums?

- As the amps only have a Powerlink going into them, i am unable to separate the L and R signals and so I would be unable to bridge each amps without ruining the stereo imaging. However, If i took the L signal from both amps and combined it down one cable and into the speaker, would this work or would it overload the amps? Would this be okay regarding impedance? (Method A on the diagram and more convenient)

- If i changed the wiring inside the speakers so in effect i was able to Bi-Amp it, i could use one amplifier to drive the L+R bass drivers and the other amp to drive the L+R tweeters. This wouldn't overload the amp, and would keep the impedance the same, however, would be more difficult and require more work inside the speaker. (Method B on the diagram).

I appreciate it would be cheaper and easier for me to replace this with newer kit, however, it belonged to a family member who i was close too and so I really do not want to get rid of it.

Please let me know if you have any more questions and all help/suggestions are greatly appreciated.

Thanks, 
A.
