Bi-amping a DR250

#1 Post by SingeStepper »

Hey guys,
So I've inherited from the internet a pair of DR250s and I keep having trouble with the DIY crossovers inside. From literally falling apart, a capacitor blowing etc....

So I'm wondering has anyone tried Biamping their DR250s?
Reckon my biggest concern is what to power the tweeter array with... Anyone have any insight here?

Which tweeter array do they have? If caps are blowing it could only be because they're not up to spec.

Sorry you are having crossover issues, Bill is right though maybe the crossover wasn't built correctly in the first place.

I was bi amping my DR200s that I had built, quite successfully and was able to use a pretty small amp. Peavey IPS150, then Peavey IPS400 for the mids, crossed over using the DBX Driverack. I started by setting the voltage limit for the mids, then just brought up the highs till it sounded right. Required very little gain.
Totally overkill, but it was fun :D
I downsized to OTop 8's with a crossover.
