Hello, everyone! I’m in the process of building the Lepai powered / active DINAS and I am looking for a couple of clarifications from the build plans which I couldn’t find in the forums
* the plans indicate the tweeter & woofer are wired with reversed polarity. possibly for phasing? is that the correct wiring?
* there isn’t any mention of internal damping, either for the full range driver (sealed internal enclosure) or the woofer. Has anyone tried damping materials and are they beneficial?
* there are 3-4 reports in the forums of audible hum (60hz) which are traced to either bad or mis-matched switching PSUs. Is this common and should I consider running both speakers from a single PSU (with a pigtail to split the feed to each speaker)
FWIW, I’m leaning towards having the plate amp on an external mount (separate enclosure on the rear) so that if I change my mind and go with the passive setup in the future I don’t have to fill in a big hole where the amp was mounted.
Thanks in advance for any help!
