Hello DiyAudio,
I recently acquired a pair of Duntech Sovereigns (mid-west US) and am trying to figure the feasibility to convert them from single to biamp inputs. Attached are a few pics. While I have done some basic repairs, I have limited experience with crossovers having this many components. Yikes, they are even on drawer slides.
My wife and I collect equipment from the Sov's era, back when I was school-aged, when seems all the cool kids in the magazines had more than one amp. I have some amp pairs that are not easily bridgeable that I'd love to use with the Sovereigns.
Ask any questions. I'll do my best to respond. Thanks in advance for any input.

Hello
Sure you want to modify them? If they are in good shape and it's your first time doing this might want to use something else.
Wow the drawer is a great idea you have a schematic? Can you determine the component values? Looks like the caps are all painted. If you are talking full up Bi-amp you need to know what the voltage drives are and be prepared to make changes. If you remove 1/2 of a bandpass circuit you will typically need to make adjustments to the remaining half.

I assume you want to passively bi-amp this speaker.
Please unplug the 2 red wires and 2 black wires connected to the binding posts, measure the relative resistance of all four connectors on the crossover board with an ohmmeter and post the results.
In this way, it should be possible to determine which pair of connectors belongs to high-frequency and which pair of connectors belongs to low-frequency.

Using two amp sides per speaker won't gain much (if any) headroom, the peak power demands are still the same for a given SPL.
The woofers are crossed ~300Hz, where most of the highest peak (and sustained) power is required.
What amps do you have, and what are you hoping to achieve?
