I appreciate the last video posted because it showed the insides of the speaker......great cabinet and damping for the money......but the xover, and wires and push on connectors and input connectors are just ordinary Chinese good parts. Wait till someone removes the xover and does a super outboard xover using state of the art parts and wires and hardwired inputs. If someone in the Bay area gets a pair they can bring them here and I will do what I just suggest. Will blow your mind how much better they will be with super outboard xover.....................However, even better would be to just hardwire some super wire directly to the voice coil wires of the drivers and remove the crossover and store it away somewhere. Remove the binding posts from the plate and run the wires outside long enough so they go to the floor underneath the speaker where you hook the wires up to a Peachtree Gan1 digital amp......one stereo amp per channel. You get a Minidsp Flex all digtial xover and you bi amp using the two Peachtree amps......all connected together with coax digital cables. You can use a streamer into the xover or if you just want to play a cd player you can run that into the xover and use the volume control in the xover. Digital amps like the Peachtree (more coming....real soon) allow you to get rid of your DAC, preamp, normal amps, and analog cables......the purity is amazing and when you get rid of the ordinary xover parts in the speaker and bi-amp you will be in heaven. You set the xover point at where Andrew started (1.6K) but with steeper slopes you could probably run the tweeter to 1 K or lower with even more transparency. With the digital xover you can do anything you like....eq, crossover freq....slope....delay......super fun.
This speaker biamped using two GaN based digital amps will simply blow, blow blow your mind.....gently down the stream....he he.
