how to connect to symmetric out?
I built small el-pipe-os with 15cm diameter and
tuned them to 30Hz or so (had some cheap drivers lying around)
The problem is, I run symmetric D1- and aleph-ono- output into the aleph 30 power amp (passive pre) and want to use an old Rotel for the pipeos.
How can I connect the active subwoofer filter described in the article? Do I need a transformer or is there a cheap trick that would do it?
Every time I tried connecting it so far I got big hum
I rather don't want to take the power amp output for a passive filter because they're too far away.
thanks -
