Hi guys, is it possible to modify the existing crossover of Dynaudio Audience 52 for biwiring?
The reason I am asking this is because I am using Acram AVR300. It allows using surround back L/R for biamping.
I just bought this set of speakers 2nd hand. Its 4ohms and 86db, so I think this will provide more power to the speakers.
Thanks

It's possible with every multi driver speaker.
Bi-amping like you described is usually not for more power especially with a small 2-way, the tweeter uses only a little fraction of your amp capability. AVR-s is usually power supply limited, sometimes the nominal Wattage is only with 1 channel being driven.

According to the specs, its 120W per channel with 2 channels into 4ohms. I am just using the amp in stereo mode (for both movies and music). So, I am hoping to be able to drive the speakers.
No, it isn't. Serial crossovers need the other driver(s) as essential part of the filter function.
I forgot series crossovers. But can converted to a parallel one, even if it may not be exactly the same.
Anyway the main advantage i see with passive crossover bi-amp is that you don't need to use padding resistor on a more sensitive driver. But then you need to account that into the passive network and able to set different gains on the amps.
120W per channel is more than enough for this little speaker.
No, you just need a new crossover, whether this is difficult or not is an another thing.
Otherwise, if we want to give the OP an accurate answer, we must finally know the schematics of these Dynaudios. But I bet it doesn't have a serial crossover. Nonetheless, I wouldn't force the bi-amping in this situation.

I forget that often too. 😀
Yes, that's true. I find a different use also very appealing, a solid state amp with authority for the bass driver and a tube amp for the tweeter. That way the smaller output transformers for the tube amp cost only a fraction of the ones for real fullrange. With electrostatic mid/high you save transformers and even the high voltage power supply (anode voltage used for that).
Definitely. Most of the time the used power is even below 2W.
Here is the crossover of the Audience 42. The one of the 52 will be similar or even close for the tweeter. From the board + input leads a copper path to the first parts, the woofer coil and the tweeter capacitor. If you cut the copper path before the tweeter cap, you can solder the + pin for the tweeter to it and to the tweeter terminals, the - has to go from the common - to both of the - terminals (woofer/tweeter).
If you want a complete separation (the - too), you have to build one of the crossover branches on a new board, at least that makes it a lot easier and cleaner and is reversible since you don't have to cut a copper path on the board.

Oh i see... thanks everyone!!!
I think i will work on improving the crossover instead. It does look horrible.....

Well, that's exactly the same. Except you have to develop it completely yourself. The only thing you could actually improve without modifying it completely would be to replace the electrolyte capacitor, all other parts are already of very good quality.
It most certainly is, although next owner, if that ever happens, won't favor any mods made to the original design, so perhaps you should think ahead in that sense.
Chopping the crossover "in half" (assuming parallel) will change the impedance profile. Whilst this wont affect frequency response - it may cause 2 * 4 ohm loads to be seen by both crossover legs. Many receivers are multi-8 ohm speaker tolerant, but not 4 ohm.
Besides, I'd wager the total current supply is fixed and gets spread amongst each pair of speakers wired. therefore, you could wire up the surrounds, but leave less current draw available for the woofers (mains?).
Better quality amplification might be a better path. Look for a good used power amp (250w+) assuming the arcam has pre-outs.
