Pioneer HPM-900 speakers
« on: 7 Mar 2023, 04:01 pm »
Anyone out there upgrade the components on the crossover for the Pioneer HPM-900?

I want to do a full DIY upgrade with all new components from GR-Research.
New wire
tube connectors
zero rez

The crossover has a transformer on it for the super tweeter and I dont know if that can be upgraded. Thoughts?

  • To whom more was given more will be required.
    • Never go to a psychiatrist, adopt a straycat or dog. On the street they live only two years average.

Hi,
The Starting Block Circle is really for people to introduce themselves.
This question/thread is best posted in the GR Research Circle, so I will move it there for you now

You might consider sending one in. We can take some measurements on it and see what it is doing and make sure there are no issues that need to be resolved before upgrading the parts.
